The Case for Treasuries, Revisited

In April of 2009 I wrote a post called The Tentatively Bullish Case for Treasuries in which I listed the typical arguments against treasuries and presented my reasoning as to why each argument would likely prove wrong. My tentative conclusion was that the odds favor treasury yields moving lower in the medium term (i.e., on a timescale of several years or more... I had and have no idea about short term month-to-month movements.) The prior post is a bit long but the content is theoretical rather than tied to specific events in 2009 so it should still be a relevant read today.

The conclusions I made then (and have been arguing for several years) have not changed, and probably won't unless the private sector halts attempted deleveraging and starts adding debt in a sustained way. Such renewed debt growth is possible (Australia seems to have achieved it, though how sustained it will be is unclear) but there is no evidence of it yet for the US, and the odds are strongly against it given the fundamental forces in play. (Note, the theme of deleveraging has become a more mainstream view, as for example exemplified by this McKinsey report on the global debt bubble and its consequences.) Anyway, as of December, US consumer credit (which doesn't include mortgage debt) is contracting at a record rate:


Consumer credit is a key gauge, but total private sector debt is still being reduced too, as shown in the graphs in my summary of the last Fed Flow of Funds report in December.

In this post I'll attempt a condensed summary and update of the prior post on treasuries plus add in some relevant third party perspectives.

The Historical Record

Government bond yields declined during both the Great Depression in the US and in Japan since its bubbles burst around 1990. These represent two different resolutions to debt bubbles — debt deflation amid severe depression, or large ongoing government stimulus and slow semi-stagnant growth as private sector debt is serviced and reduced. We are currently tracking closer to the latter scenario, but the former is still a real risk. Both scenarios were friendly to government debt prices in the past. More details and charts are in the old post.

Inflation?

The Federal Reserve cannot create inflation in consumer prices or wages (see here for one of many explanations of why... or read my prior post). The Treasury can create inflation with sufficient deficit spending, but future attempts at fiscal stimulus large enough to do so are at significant risk of political gridlock.

And the actual outcome so far? Look at the price level trend as of December 2009 in the chart below (from this deflation watch post). The increases (since the plunge at the end of 2008) shown by the red line are losing momentum and flattening out earlier than occurred in Japan. If the current sell-off in commodities and risk assets intensifies (prices have been looking bubbly!), the already stalling CPI changes could be shocked back into negative month on month territory for long enough to feed a self-reinforcing deflationary psychology in consumers.

Potential for Default

My April 2009 post argued that sovereign debt default was not a risk given the historical precedents. Since then I have had this view reinforced by the discovery of Modern Monetary Theory (Neo-Chartalism). More on that another time as I have been meaning to write about it for months, but one point it explains is why a sovereign nation that spends and issues debt in its own freely floating currency never has to default on domestic currency debt (though in very rare cases it may choose to for political reasons).

Too Much Treasury Supply?

In the prior post I addressed the then near-universal concern in the econoblogosphere that the huge pending supply of treasury debt would overwhelm demand. I prefixed my reasoning as to why the government spending (via its associated increased supply of government debt) would create its own demand for government debt by saying "my perspective on [this] I have not seen detailed anywhere else, which suggests it is novel, wrong, or simply something that no source I read has bothered to explain in detail because they thought it obvious."

It turns out that through simple step-by-step reasoning via examining macroeconomic balance sheet impacts I had discovered by accident some of the core principles of Modern Monetary Theory (Neo-Chartalism). I have been trying to learn more of the strengths and weaknesses of Chartalism since early fall but have not addressed all my questions sufficiently yet to do a post on it (I do think the strengths outnumber the weaknesses). But one proponent, Warren Mosler, puts it succinctly in red text right on his site margin: "The funds to pay taxes and buy government securities come from government spending.". I'm putting something together to help give a more detailed overview of the accounting perspective, but the bottom line is that it is the government's spending that creates the private sector's wealth that can be used to [among other things] buy government debt. When the private sector is not issuing net new debt at the same time as government is, there is no competing supply of debt, so bond prices will not be driven down by excess supply.

Will China Stop Buying?

I continue to think this concern is mostly irrelevant but don't want to go into a lot of detail. However I will give one analogy.

I recently saw a posted graphic showing recent net migration between US states over recent years (now I can't find it). Imagine someone looking at how much Californians have spent buying US Treasuries in the last year, then seeing that migration trend (I think California was net negative) and declaring "uh oh, if Californians stop buying our treasury debt, who will?!?" The obvious answer is that now there will be more Oregonians, Arizonians, etc to buy the debt.

While it's not a perfect analogy, the China scenario is similar in that the US consumer decision to buy Chinese goods is what provides the buying power to China that allows them to buy dollar-denominated investments with the proceeds. If consumers save instead of spend, or buy US goods and services instead of Chinese ones, that flow of money and potential savings simply is in the hands of US investors instead. To suggest this would generate no increase in domestic treasury demand implies thinking only central banks are "irrational" enough to buy sovereign debt and that there are not enough relative-value arbitrageurs to move prices meaningfully in response. That may hold true for short periods of time, but indefinitely? I'm not convinced.

Quantitative Easing

Quantitative easing has likely supported government debt prices to some degree, and it is winding down (for now). I argued before that QE would be an extra demand support for treasuries, but I don't think prices must reverse when the buying stops. The direct treasury purchases by the Federal Reserve have already ended, and treasuries are doing just fine since then. I also suggested that the impact of reduced supply (as the Fed takes assets off the market) would also be supportive of prices. Chartalists also make the very insightful point that QE is actually net deflationary as it reduces non-government sector income by replacing higher yielding bonds in the hands of private investors with low-yielding "money" (currency and deposits backed by bank reserves).

Sentiment

Sentiment has been wildly bearish on treasuries throughout 2009 and they remain one of the most despised asset classes. I've seen reports that short interest on government debt is among the largest of any asset class (perhaps mostly due to inflation fears). I still suspect that this doesn't leave much room for more bearishness, and leaves sentiment-driven changes much more likely to drive prices up rather than down.

Reasons This Tentative Bullishness Could Prove Wrong

To address the reasons I listed under this heading in the old post:
  • "Though right now it seems politically unlikely, the government could end up trying to swap more private debt for public debt than can ever hope to be serviced by taxpayers.". This seems more and more unlikely to me, especially since I dug into the Japanese debt data and discovered that public debt issuance has exceeded private debt reduction over the last two decades and still yields plunged. Also the Chartalist perspective points out that paying taxes isn't exactly the same as servicing debt (again, more on this later), as sovereign governments are not revenue constrained.
  • "...potential for significant political instability as a result of the crisis could lead to very unpredictable consequences..." Still a risk, but probably not in the near term.
  • "A huge supply shock (energy, other natural resources, labor, etc) could potentially ignite meaningful inflation..." Still a risk, but the odds seem no higher than before.
  • "...underfunded obligations like social security..." Still unclear on how much and how soon this could impact on treasuries, but likely not an issue in the medium term.
  • "Perhaps my logic in this post is just plain wrong." On the contrary, my discovery of the Chartalist school suggests to me that the balance sheet based reasoning was accurate. Of course readers may still disagree and tell me where I'm wrong!

Gary Shilling is one of the minority who have remained publicly bullish on treasuries, and he gives his reasons.

The Asset Dearth and the Japanese example and Disappearing Assets, Continued
"Why are asset prices so high? One reason is that there aren’t enough of them... The net creation of private assets has actually fallen... The only sector of the US economy presently dis-saving is the US government... the banks use the cheap credit to buy government debt, because no other kinds of debt are available."
David Goldman makes the point I have made repeatedly while looking at the Z1 Flow of Funds releases starting last August in a post titled Why Treasuries Find Buyers and Interest Rates Will Not Rise (Much). For example I said: "people will buy (and have been buying) treasury debt because there are on aggregate less other fixed-income asset choices available on the market, and the new treasury issuance fills the 'hole' left by the shrinking supply of private debt as it is paid down or defaulted on."

Another post (from December) by David Goldman listing reasons to be bullish on treasuries.

Finally, Paul Krugman points out back in November that "the same people now warning about the alleged Treasury bubble dismissed warnings about the housing bubble."

Conclusion

I still do not understand why even most commentators who expect ongoing private sector debt reduction (as opposed to those in the full V-shaped recovery, new bull market camp) have been so bearish on treasuries. I think it is based on false (or out of context) textbook economic arguments about government deficits creating inflation, etc. The logic as to why government debt performed well during past deleveraging cycles seems clearer than ever to me now that I have learned some of the Chartalist/MMT perspective (again, more on that later).

So the real unknown is simply whether we can escape that outcome in any sustainable way. In the early 2000s it involved a new and even larger debt bubble in housing. Maybe this time we will have the miracle of rapidly growing exports and the rest of the world quickly achieving sustainable domestic demand (both of which were positive factors for Japan) and also escape private sector deleveraging (which Japan did not). If and when evidence of that appears I'll be likely to change my case regarding treasuries.

Deflation Watch (December 2009): Price Level Trends Relative to Past Debt Crises

This is another update (with November and December's data added) to the series of posts on US price level trends that started with Price Deflation Today versus the Great Depression and Post-1990 Japan — Comparative Charts (which had data through July 2009). The original post contains the most in depth discussion of the comparisons between the three episodes, so please look at that if you have not already.

This one will be briefer than sometimes as I want to focus on some new topics (on which I will post in the future).

In summary, headline consumer price level increases seem to be slowing markedly following their sharp early 2009 rebound from the late 2008 plunge levels. Clearly we have not followed the path of Great Depression deflation, but the US price level trend appears to be flattening out much sooner than occurred in Japan, as the graphs below show. While mild deflation may be more probable, we could still be at some risk of a sharp price deflation, in part because commodity prices in particular seem (to this observer among others) to have risen too far too fast. A lot may hinge on the combined questions of (1) how much investor speculation in commodities (which is subject to quicker reversal than end-user demand is) has impacted their prices, and (2) how much and how abruptly China's growth slows. Though of course other factors such as the direction of broader asset prices (stocks, housing) and government policy are also very relevant to the CPI outlook.

These are my definition related comments from a previous post:
As noted previously, "deflation" is often discussed in broader terms than simply price level:
  • Contraction of money and credit (broad money supply)
  • Deflation in asset prices
  • Deflation in a representative "basket" of consumer and producer prices
  • Deflation in wages
The various measures are often somewhat correlated but they only track to each other loosely. In the Great Depression prices fell faster than wages, yet wages (along with asset prices) still fell enough to propagate the adverse feedback loop of debt deflation in which income falls but debt obligations remain at the same nominal level, increasing the burden of the debt. Deflation in asset prices (triggered by the bursting of debt-financed asset bubbles) generally precedes the other deflationary trends.

CPI-U 12 Month Changes (source: BLS)

I think the year-on-year graph is deceptive when prices are as volatile as they have been. Compare it to the price level trend graphs below.

BLS Summary Comments:
"On a seasonally adjusted basis, the December Consumer Price Index for All Urban Consumers (CPI-U) rose 0.1 percent, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the index increased 2.7 percent before seasonal adjustment.

The seasonally adjusted increase in the all items index was broad based, with the indexes for food, energy, and all items less food and energy all posting modest increases. Within the latter group, a sharp rise in the index for used cars and trucks was the largest contributor to the 0.1 percent increase, while the indexes for airline fares, apparel, and lodging away from home rose as well. In contrast, the indexes for rent and owners' equivalent rent were unchanged and the index for new vehicles declined.

Grocery store food indexes showed broad-based increases, leading to the food index rising 0.2 percent, its largest one-month advance in over a year. The energy index also rose 0.2 percent; this was its smallest increase in five months. The indexes for fuel oil and gasoline rose, but the electricity index was unchanged and the natural gas index declined."

Deadlock! Total Borrowing Has Stabilized at a Mild Contraction Rate as Private Debt Reduction Stops Increasing and Government Borrowing Stays Steady

The latest Federal Reserve Flow of Funds report shows a rough continuation in Q3 2009 of the Q2 trends in borrowing. However, the big news is that it has become clearer that the private sector's negative rate of borrowing has stopped increasing and has stabilized at a level roughly opposite to the government's positive rate of borrowing.

(click on graph for a larger version)

The above chart shows the borrowing rate as a percentage of GDP for government (federal, state and local), the private sector, and the total of the two from 2003 to Q3 2009. Last quarter it was unclear whether the rate of private sector debt reduction would keep increasing or stabilize, and for now it has stabilized (actually a slight decrease, with the trend unclear). The result is that the rate of total borrowing has stayed between -1% and -3% of GDP for the first three quarters of 2009. Some thoughts on the details:
  • Steve Keen often discusses the "debt contribution to demand", i.e., borrowing adds to total demand and reducing debt subtracts from it. This stabilization in the rate of total borrowing (and its associated spending) since Q1 likely is one of the larger factors in the stabilization of GDP in Q2 and Q3 from a state of freefall (see graph on right). But see the following caveat on how this conclusion could be flawed.
  • This data is a somewhat crude proxy for debt's contribution to demand in the sense that some government borrowing (e.g., TARP) goes to propping up balance sheets rather than supporting spending on goods and services and thus incomes. Similarly, private debt contraction is still dominated by the financial sector, the debt of which likely has a less direct correlation to GDP-related spending than does household credit, for example. Perhaps I will try separating these in a later post, but it may not be feasible to do well.
  • One of the reasons why treasuries have no trouble finding buyers (more details in posts here and here) is that in a balance sheet recession, public debt simply fills the "hole" left by disappearing private sector debt.
Will this deadlock hold in future quarters? There are several possible scenarios that I still plan to cover in a separate post. A negative one of non-trivial probability is "double dip" recession with re-accelerating private debt reduction unaccompanied by sufficient public sector borrowing to offset the falling demand and therefore GDP. In another scenario, if the current "deadlock" were to continue as is, there would no longer be the ongoing annual increases in debt that have added to aggregate demand over recent decades (a point often emphasized by Steve Keen). This would imply a much lower level of annual growth in GDP than most expect, and is closer to the Japan outcome than the Great Depression outcome.

Evaluation of these debt trends is complicated by the huge size of both financial sector and Federal government changes in borrowing relative to other sectors:
(click on graph for a larger version)

Mortgage debt and consumer credit are being reduced (these are typically cited symptoms of attempted deleveraging) but they are dwarfed in absolute terms by the debt reduction of the financial sector, at least so far. In relative terms (debt reduction relative to stock of existing debt of that type) the rates are slightly closer: as of Q3 around -9% for the financial sector, -4% for home mortgage debt, and -3% for consumer credit. This chart shows the annualized rates by sector:

Dividends Are Still Trending Worse Than The Great Depression

With S&P 500 earnings reporting mostly (98%) complete for Q3 2009, it's time for an update to the charts from Dividends, Earnings, and Stock Price Trends have Tracked the Great Depression.

The following chart compares the decline in twelve month trailing earnings and dividends since the stock market peaked in October 2007 to the same measures following the stock market peak in September 1929:

(click on chart for a larger version in a new window)

Earnings have dropped more rapidly than during the Great Depression (dramatically so if you count reported rather than operating earnings), but they appear to have begun a recovery much sooner than occurred back then. Trailing 12-month dividends are still falling slightly faster than during the Great Depression, which is particularly remarkable given how much more severe deflation was then compared to now. These trends underscore that contrary to some claims, this is no crisis of confidence!

Since dividend changes tend to lag earnings changes, rising earnings could mean dividends will level out and start increasing soon (and in fact the quarterly fall in dividends from Q2 to Q3 was small). However, if earnings are being over-reported thanks to factors such as relaxed accounting rules or optimistic loan loss assumptions, dividends should ultimately reveal the truth about underlying cash flows.

And while we should all hope that this recovery can be sustained, there is a significant probability (details of which I hope to discuss in a separate post) that this is a temporary upturn in a longer term depression. A renewed fall in GDP, persistent unemployment, and intensifying deflationary pressures would not be good news for any fledgling recovery in earnings and dividends.

Here is a chart comparing the dividend yield today with the Great Depression trend. Yields are much lower today and are trending down again despite the significant upward yield trend back then. So is this a genuine early economic recovery, or a sign that the modern stock market tends to be a capital-gain seeking momentum machine with little regard for underlying fundamentals? Yes, interest rates are low, but they were back then too, and David Rosenberg suggests most current corporate bond yields are a lot more attractive than yields of the same companies' stocks.

The next chart compares price/earnings ratios earnings during the Great Depression with today using reported earnings. There is no comparison.

It is clear that the market has accepted Wall Street's encouragement to ignore reported earnings when valuing stocks, so here is the same price/earnings chart using operating earnings (for the recent trend — the measure had not been invented back then):

(click on chart for a larger version in a new window)

The P/E ratio based on operating earnings has soared above 25 just as it did at a later stage during the Great Depression. I just wish I had more confidence that this was the start of an earlier sustainable recovery rather than a sign of the irrationality of markets and reckless myopia.

Note: All of these charts use Robert Shiller's monthly stock data (with a single representative stock price for each month), not daily prices.

Deflation Watch (October 2009): Price Level Trends Relative to Past Debt Crises

This is another update (with October's data) to the series of posts on US price level trends that started with Price Deflation Today versus the Great Depression and Post-1990 Japan — Comparative Charts (which had data through July). The original post contains the most in depth discussion of the comparisons between the three episodes, so please look at that if you have not already.

I'm posting updated charts as the data is released each month, but for now since time is scarce I will keep the commentary minimal... I will have more to say if and when the current price level trends change more significantly.

October shows a minor increase in price level for many components of the CPI. According to the BLS much of this is energy and auto related, but while disinflation is still apparent when looking at 2009's trend, strong deflation has yet to reappear in any CPI components. The big question is if and when this will change. While I expect it will, time will tell.

These are my definition related comments from a previous post:
As noted previously, "deflation" is often discussed in broader terms than simply price level:

BLS Summary Comments:
"On a seasonally adjusted basis, the Consumer Price Index for All Urban Consumers (CPI-U) rose 0.3 percent in October, the U.S. Bureau of Labor Statistics reported today. The index has decreased 0.2 percent over the last 12 months on a not seasonally adjusted basis.

The seasonally adjusted all items increase largely reflected advances in the indexes for energy and for new and used motor vehicles. The energy index rose for the fifth time in the last six months, advancing 1.5 percent as the indexes for gasoline, fuel oil, natural gas, and electricity all increased. The index for all items less food and energy rose 0.2 percent in October, the same increase as in September. The indexes for used cars and trucks and for new vehicles both rose sharply and together they accounted for over 90 percent of the increase in the index for all items less food and energy. The indexes for airline fares and medical care also increased, while the shelter index was unchanged and the indexes for apparel and recreation declined.

The food index also increased in October, rising 0.1 percent after declining in two of the previous three months. The index for food away from home increased slightly, while the food at home index was unchanged. Within the food at home group, the index for dairy and related products rose significantly, while the fruits and vegetables index declined for the fourth straight month."

Global Price Level Trends Show Varied Inflation/Deflation Across Housing Bubble Countries

While looking at US consumer price level trends in prior posts (starting in September), I have pondered the differences between the Great Depression experience in the US of severe deflation and Japan's post-1990 slower-onset milder deflation to assess today's risks. Factors that could in some combination explain this historical difference in severity include:
  1. A greater amount of government stimulus applied by Japan to maintain aggregate demand.
  2. Japan's post-asset-bubble balance sheet recession occurring in the context of a booming global economy, which would support demand for Japan's output via strong exports to the rest of the world, as well as put a floor under commodity prices.
  3. Consumer prices in modern economies potentially much "stickier" than was the case in the 1930s, due to a larger share of complex goods in our typical consumption "basket", plus a large services sector, neither of which seem likely to be dragged down rapidly by falling commodity prices. (Labor prices are are generally not renegotiated daily like commodity prices). If accurate, this could suggest modern economies are less likely to enter the vicious spiral of self-reinforcing deflation.
  4. Larger upward inflationary momentum at the time of the asset bubble burst. In the US, when the stock market and credit bubbles started bursting in 1929, three out of four CPI components were already in mild to moderate deflation. Japan had roughly 3% inflation at the time of the stock market bubble peak and it was almost eight years before the consumer price level peaked.
In gauging the accuracy of the above potential factors and their relevancy to today's crisis, it may be helpful to look at the price level trends of various modern economies that have experienced asset prices bubbles leading up to the 2007-2009 global financial crisis. This post will include graphs for the following countries:
  • the US (for obvious reasons)
  • the UK, Ireland, and Spain (as the three most bubbly major European economies, at least with respect to housing prices)
  • Japan (the world's second largest economy, and of interest to see what happens decades after asset bubbles burst)
  • Australia (as a major commodity exporter that also has a housing bubble, and apparently the only major economy to so far escape a technical recession)
  • the Euro 27 area (the largest aggregation of Euro countries offered by eurostat)
  • Iceland (a bit of an outlier in part due to massive externally denominated debts and different crisis dynamics to date, but of interest for comparison purposes)
I initially attempted to include China's data, but only year over year changes are provided for each month, so there is insufficient data to reverse-engineer back to the raw price level data.

Here is a chart of consumer price level trends for these countries, with all price levels normalized to 100% at July 2008 (which was the peak of the non-seasonally-adjusted US price level):

Some observations:
  • The US CPI has been the most volatile — the fastest rate of increase leading up to summer 2008 (excepting Iceland), and the most rapid deflation in the second half of 2008. Perhaps this reflects a greater CPI weighting to energy than the other countries.
  • Iceland's price level inflation has been so dramatic relative to other countries that rather than show the full climb (from 87% to 118%), I zoomed in the chart to make the differences between other countries more visible. I'm not sure to what extent this inflation was driven by falling currency exchange rate versus other factors.
  • Spain and Ireland (but especially Ireland) appear to be in the strongest deflationary trend among European countries included here.
  • Spain and Japan have tracked closely to Ireland since mid 2008, but are in 2009 showing a little more price level stabilization than Ireland.
  • The UK and Australia each paused in their price level ascent in the second half of 2008, but their prices have marched higher again in 2009. Probably not coincidentally, both countries have seen housing prices rebound and set new highs (I have read this but not confirmed the data).
The next two charts show the annualized trailing three month inflation rate for each country. The charts are identical other than the Y-axis scale — the second shows the data in full, while the first is zoomed in, excluding most of Iceland's data points, to better see differences in the other inflation rates. Note these are probably extra volatile because many of the data series are not seasonally adjusted.

Some observations:
  • All the countries except Iceland experienced a dramatic decline in inflation at the end of 2008. Even the least affected, Australia, still had a negative three month annualized inflation rate lasting three months. This is very likely the result of global commodity price declines in the second half of 2008, underscoring that some price level influences truly are global.
  • Iceland's inflation rate soared in early 2008 and has been declining ever since. It is still the highest rate of the countries I've shown, at 8% (July-September 2009, annualized), but has been dis-inflating rapidly from a peak three month annualized rate of around 30%. I have wondered whether at some point Iceland could fall into deflation, since at least a couple years ago its domestic credit levels looked quite high relative to GDP. I don't know what the domestic debt dynamics are currently and perhaps the dynamics of a huge external debt level contribute more substantially to macroeconomic developments.
  • Only Australia has had a three month annualized inflation rate that has climbed consistently through 2009 (September is the latest data). The UK diverges from Australia with its three month inflation rate declining since April 2009 (but it did increase faster at the start of 2009).
  • Excluding Iceland, the most recent data point, September 2009, shows a range from around 4% inflation (three month annualized) in Australia down to around -4% inflation (i.e., deflation) in Ireland.
Concluding Thoughts

This was a very rough high-level look at relative price level trends and short term inflation rates over a sampling of housing bubble countries and other countries of interest (Japan, Iceland). More insights would be likely with additional analysis such as adjusting for exchange rate trends, comparing rates of government deficit spending, comparing changes in private debt levels, etc.

The price level trends across countries show some correlation at times (e.g., late 2008), suggesting global macroeconomic factors matter to some degree, but also diverge significantly at other times (e.g., the current -4% to 8% range of 3-month annualized inflation across countries), suggesting domestic country-specific dynamics are the dominant factors in price level trends, even at times of global recession/crisis.

There are at least three key domestic dynamics that could be most heavily influencing price levels. One is the degree of government stimulus relative to the contraction in private spending. A second is whether private debt bubbles have actually popped or are still growing. A third would be the relative size of these debt bubbles (total debt-to-GDP) and their recent rate of growth (since added debt contributes to annual aggregate demand).

I have not included enough data in this post to evaluate these factors for each country. But at the risk of being wrong, my current assumption is that size of government response is the number one differentiating factor, and some countries are maintaining a stronger private-sector bubble mentality than others (e.g., with respect to Australia's housing prices). If government stimulus proves politically unsustainable, or private sector debt bubbles collapse and prove to be overpowering, it could be that countries like Australia will simply lag countries like Ireland with respect to consumer price deflation. Ireland may be the country to watch — I've seen suggested that it may have begun a full scale debt deflation.

Endnotes

Note that different countries construct their CPI measures differently, so some trend differences likely reflect what each country considers a representative "basket" of goods and services. Also the US, UK, Ireland, Spain, Iceland, and Euro 27 price levels are not seasonally adjusted. I think the data I found for Japan's and Australia's are seasonally adjusted, but I am not certain.

The reason I like looking at absolute price level trends right now rather than just rate of change (typically year-over-year) is that when price levels are not moving in a single direction (until the recent deflationary trends, the direction of CPI indexes was primarily up), then the year over year change only incorporates two data points at a time, and is therefore especially volatile and doesn't reveal the big picture as well.

Deflation Watch (September): Price Level Trends Relative to Past Debt Crises

This post updates the charts from Price Deflation Today versus the Great Depression and Post-1990 Japan — Comparative Charts (which had data through July) and the August data update with the data for September. The original post contains the most in depth discussion of the comparisons between the three episodes, so please look at that if you have not already. My current plan is to update this post each month after PPI and CPI data is released as long as the comparisons remain interesting.

These are my definition related comments from the previous post:
As noted previously, "deflation" is often discussed in broader terms than simply price level:
  • Contraction of money and credit (broad money supply)
  • Deflation in asset prices
  • Deflation in a representative "basket" of consumer and producer prices
  • Deflation in wages
The various measures are often somewhat correlated but they only track to each other loosely. In the Great Depression prices fell faster than wages, yet wages (along with asset prices) still fell enough to propagate the adverse feedback loop of debt deflation in which income falls but debt obligations remain at the same nominal level, increasing the burden of the debt. Deflation in asset prices (triggered by the bursting of debt-financed asset bubbles) generally precedes the other deflationary trends.
Some Relevant Current Articles

In BLS Owner's Equivalent Rent Numbers From Twilight Zone, Mish looks at the surprisingly small decline so far in rent and owners-equivalent-rent measures:
"With home prices crashing year-over-year and both housing rents and apartment rents dropping as well one might think that falling rents would be reflected in the CPI."
Mish subsequently looks at the September CPI data in Year-Over-Year CPI Negative 7th Consecutive Month; Rents Decline First Time In 17 Years.

While many have expected falling rents and their eventual impact on reported CPI, Calculated Risk has been bringing the topic up more recently, for example, here:
"Anyone analyzing the tax credit should call the economists at the BLS and ask about how falling rents will impact owners' equivalent rent and CPI. Then call the economists at the Federal Reserve and ask how CPI deflation will impact consumer behavior and monetary policy. Welcome to the Fed's nightmare."
The BLS methodology for calculating owners' equivalent rent (weighted at 23.8% of the entire CPI!) is to survey homeowner households. Given people's likely lack of close knowledge of the current rental market, lack of objective perspective of their own home's rental value, and lag effects of changing home prices, rents and perceptions, it is no wonder that the BLS measure has not fallen at the rate anecdotal experience suggests it should have. The BLS says on its guide to Consumer Price Indexes for Rent and Rental Equivalence:
"However, the expenditure weight in the CPI for rental equivalence is obtained by directly asking sampled owner households the following question: If someone were to rent your home today, how much do you think it would rent for monthly, unfurnished and without utilities?"
In China’s September data suggest that the long-term overcapacity problem is only intensifying, China expert Michael Pettis discusses (among other topics) the level of China's commodity imports. He quotes someone else regarding China: "the recent pace of commodity import growth has been much faster than justified by the rise in current demand." Pettis then says:
"It seems that there may be another explanation, and that is stockpiling by private investors. From what I am being told, it seems that a number of wealthy Chinese investors have been speculating directly in commodities, and so some of this inventory buildup is occurring not at the company level but at the investor level."
The potential for a sharp drop in commodity imports by China (if this inventory build is accurate and if it turns out to not be sustainable and if real demand doesn't catch up quickly) is one of the reasons, even if the odds could be small, that I believe there could at some point be another commodity price "crash" similar to the second half of 2008. Those are a lot of "if"s, and they are not the only factors involved. But if commodity prices crashed in the context of other CPI components already in mild decline (food and shelter in particular have moved in this direction recently), then unlike in 2008 in which inflation in many CPI components was still high, the conditions would be more similar to the starting conditions of the self-reinforcing deflationary spiral during the Great Depression. To recap the 1930s experience, look at the Great Depression CPI Components chart later in this post (and past posts) — in 1929, before CPI started dropping rapidly, only food prices were in a rising trend — everything else was already declining.

In The September CPI with all the trimmings, Macroblog at the Federal Reserve Bank of Atlanta discusses whether the recent CPI changes really show "broad based" increases, and concludes:
"An interpretation of these data is that the September CPI increase was anything but broad-based. Moreover, the data seem consistent with the idea that prices overall are on a path of disinflation."
I'll start including a trimmed CPI chart with the others (below).

Price Level Charts for September

CPI-U 12 Month Changes, 1999 to Present (US) (source)

(click on chart for a larger version in a new window)

BLS Summary Comments:
"On a seasonally adjusted basis, the Consumer Price Index for All Urban Consumers (CPI-U) rose 0.2 percent in September, the Bureau of Labor Statistics reported today. The increase was less than the 0.4 percent rise in August. The index has decreased 1.3 percent over the last 12 months on a not seasonally adjusted basis.

The seasonally adjusted increase in the all items index was broad based, although tempered by a decline in the food index. The all items less food and energy index increased 0.2 percent in September after increasing 0.1 percent in each of the previous two months. Contributing to this increase were advances in the indexes for lodging away from home, medical care, new vehicles, used cars and trucks, and public transportation. The increase occurred despite declines in the indexes for rent and owners’ equivalent rent, the first decreases in those indexes since 1992. The energy index also increased in September, as increases in the indexes for gasoline, fuel oil and electricity more than offset a decline in the index for natural gas.

In contrast to these increases, the food index declined, falling for the sixth time in the last eight months. The index for food away from home increased, but the food at home index declined as the indexes for fruits and vegetables and for meats, poultry, fish and eggs fell sharply. Both the food and energy indexes have declined over the past 12 months. The decline in the food index is the first 12-month decrease in that index in over 40 years."
16% Trimmed CPI

This chart of 16% trimmed mean CPI (generated from the Cleveland Fed site) removes the most extreme monthly price changes, and it shows a rapid disinflation in progress (with the year over year rate of increase down to 1% so far, versus 1.5% for the core CPI), though the rate has recently slowed:

The annualized 3-month rate of change chart is new for this month. Despite being cluttered with too many lines (sorry), it does give a better sense for the rate of change of the components whose absolute price levels are shown in the previous chart. Most components are flat or down as of the three month last period. I also added the magenta line for shelter (even though it is contained within the yellow housing measure) to better show the effect of declining rents and owners' equivalent rents separated from other housing components such as energy. Shelter has been in a remarkably consistent disinflation and has just turned negative.

CPI in Japan (Jan 1980 - Jul 2009)

The peak of Japan's CPI occurred in October 1998, almost eight years after the stock market peaked, and Japan's notorious mild deflation has been in effect since then. A multi-year disinflation (of core CPI) leading to sustained mild deflation is one possible outcome for the US.

Factors Contributing to Deflation

This is a partial selection of measurable forces that contribute toward price deflation, though the core cause is the bursting of debt-financed asset price bubbles. Not all of these measures are in an outright deflationary trend, but most are suggesting at least disinflation. This data is US-specific, but US price levels will also be affected by global trends in the months and years ahead, for example with respect to whether China and other emerging economies falter meaningfully in their growth. I have kept the same set of charts even though same data updates are quarterly not monthly and as such some charts are the same as last time. No commentary on these for now — perhaps in the future.
