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:Some Relevant Current Articles
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.
- 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
- Apartment Rents "Plunge" in the West — The BLS rent measure still seems to lag reality.
- More on Falling Rents — The rental vacancy rate is at record levels, pressuring rents and ultimately home prices lower.
- Bill Gross: Fed on hold through 2010 — Pimco's Bill Gross apparently expects that unless we can sustain 5-6% nominal GDP growth over the coming years (a rate the economy is geared for) then debt deflation is likely to take hold. Unless I am misinterpreting these remarks, this is ominous, as true debt deflation dynamics would likely lead to an economy no one could deny was in depression.

- Nouriel Roubini, One on One: More Doom and Gloom — "Well in commodities, I look at oil prices. They fell from $145 last summer, came down to $30 earlier this year and now they’re back close to $80. But if I look at the fundamentals of demand and supply, demand is down to 2005 levels, supply and inventories are at all-time highs. In my view, the movement in oil prices is not fully justified by the fundamentals."

Price Level Charts for October
CPI-U 12 Month Changes, 1999 to Present (US) (source: BLS)

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.16% Trimmed CPI
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."
This chart of 16% trimmed mean CPI (generated from the Cleveland Fed site) removes the most extreme monthly price changes:

Components of US Consumer Price Index (May 1927 - Dec 1937, Great Depression)
Components of US Consumer Price Index (Jan 2006 - Oct 2009)
Annualized 3-Month Rate of Change for Components of US Consumer Price Index (Apr 2006 - Oct 2009)
The above chart shows the rate of change (over a sliding three month period) of the components whose absolute price levels are shown in the previous chart. 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.
Price Index Changes: Great Depression CPI versus Current PPI through October 2009 (US)
I added "Finished goods less food and energy" starting this month. It shows marked disinflation (and deflation for October, but that could be a blip for now).
Consumer Price Index Trends: 1990s Japan versus US Today (through October 2009) and US Great Depression
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
The measures I've been showing here recently haven't changed significantly this month, so I'm going to skip updating them this time. I'll bring them back when there are noteworthy directional changes.
