It’s good news when a monthly U.S. inflation report matches expectations. And October delivered, even though annual all-items inflation ticked higher and core remained too strong for comfort.
The U.S. Bureau of Labor Statistics reported that all-items CPI-U increased 0.2% on a seasonally adjusted basis in October, the same increase as in each of the previous three months. Over the last 12 months, the all-items index increased 2.6%, higher than September’s 2.4%. Core inflation, which removes food and energy, held steady at 0.3% for the month and 3.3% for the year.
All these numbers matched economist expectations in a clean sweep, which hardly ever happens. Inflation is hard to predict.
The BLS noted that shelter costs increased 0.4% in October, accounting for more than half of the all-items increase. Shelter costs were 4.8% higher year over year. Those increases were partially offset by a 0.9% drop in gasoline prices, which were down 12.2% year over year. More from the report:
- Food at home prices rose only 0.1% for the month, after rising 0.4% in September, and are up 1.1% year over year.
- Electricity costs rose 1.2% for the month and 4.5% year over year.
- Apparel costs fell 1.5% for the month and are up just 0.3% for the year.
- Airline fares rose 3.2% for the month and are up 4.1% year over year.
- The costs of motor vehicle insurance rose 1.2% and are up 14.0% year over year.
- Medical care services were up 0.4% for the month and 3.8% year over year.
- Costs of new vehicles were flat for the month and down 1.3% for the year.
- Used vehicle costs rose 2.7% but are still down 3.4% year over year.
Overall, while this October inflation report met expectations, it also clearly shows U.S. inflation has not been tamed. This is not good news. Here is the trend in U.S. inflation over the last year, showing the uptick in all-items costs:

What this means for TIPS and I Bonds
Investors in Treasury Inflation-Protected Securities and U.S. Series I Savings Bonds are also interested in non-seasonally adjusted inflation, which is used to adjust principal balances for TIPS and set future interest rates for I Bonds.
The BLS set the October inflation index at 315.664, an increase of 0.12% over the September number. We are heading into the time of year when non-seasonal inflation will be running lower than adjusted inflation. Don’t be surprised if we see one or two months of deflation in this index before the end of the year.
For TIPS. The October number means that principal balances for all TIPS will increase 0.12% in December, after rising 0.16% in November. Over the 12 months ending in December those balances will have increased 2.6%. Here are the new December Inflation Indexes for all TIPS.
For I Bonds. October marks the first month of a six-month string that will determine the I Bond’s new variable rate, to be reset May 1, 2025. After one month, inflation has increased 0.12%. It’s way too early to draw any conclusions from that. (But in October 2023, non-seasonal inflation fell 0.04%, the first of three consecutive deflationary months.) Here are the data:

What this means for future interest rates
Overall inflation rose in October, which was expected but can’t be welcomed. Because the numbers were in line with expectations, we can probably expect the Federal Reserve to go ahead with a 25-basis-point cut in short-term rates in December.
The effect of that cut on the economy would be minor because longer-term rates have increased dramatically in the last few weeks. U.S. 30-year mortgage rates have increased from about 6.1% at the beginning of October to 6.8% today.
From this morning’s Bloomberg report:
The figures underscore the slow and frustrating nature of the battle against inflation, which has often moved sideways — sometimes for months at a time — on its broader path down. …
“October’s CPI report remains in the same holding pattern as the past few months – inflation isn’t picking back up, but it’s also not cooling any faster,” said Anna Wong of Bloomberg Economics.
“October’s CPI report contains no information that would discourage the FOMC from cutting rates again at the December meeting,” said Michael Arnold, Bloomberg Economics Editor.
My impression is that this report changes nothing. Inflation remains well above 2.0% and will continue to be a long-term danger if the U.S. economy and stock market hold strong.

Interesting question, and it raises many issues, which I may write about later this week. My TIPS ladder ends in…
