U.S. inflation rose 0.2% in November, slightly higher than expected

The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.2% in November on a seasonally adjusted basis, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all-items index increased 1.2%.

Both the 0.2% increase in monthly inflation and the 1.2% increase in year-over-year inflation were higher than the consensus estimates. Core inflation, however, which strips out food and energy, matched the consensus estimate of 0.2% for the month and 1.6% year over year.

The BLS said the month’s inflation was broad based, with no one sector dominating the results. Food prices dropped 0.1% for the month, but remain up 3.7% over the last year. Gasoline prices, often a key factor in monthly inflation, dropped 0.4% for the month. Gas prices are down 19.3% over the last year.

Apparel prices were up a sharp 0.9%, and costs of transportation services were up an even higher 1.8%. The index for airline fares rose 3.5% in November after increasing 6.3% in October. Airlines took advantage of a bump in holiday travel, but this trend could begin reversing as pandemic lockdowns begin taking effect across the nation.

Here’s a look at the one-year trend in rates for all-items and core inflation, showing the gradual rise higher and then stabilization after the economic turmoil of February and March:

What this means for TIPS and I Bonds

Investors in Treasury Inflation-Protected Securities and U.S. Series I Savings Bond are also interested in non-seasonally adjusted inflation, which is used to adjust principal balances on TIPS and set future interest rates for I Bonds. The BLS set the November inflation index at 260.229, a decline of 0.06% from the October number.

For TIPS. The new November inflation index means that principal balances for all TIPS will be adjusted 0.06% lower in January 2021 after rising 0.04% in December. In essence, TIPS are losing a very small amount of principal over the two months. Here are the new January Inflation Indexes for all TIPS.

For I Bonds. The November inflation number is the second of a six-month string that will determine the I Bond’s new inflation-adjusted variable rate, which will be reset on May 1, 2021. After two months, inflation has been running at -0.02%, which would translate to a variable rate of -0.04%. A lot can happen in the next six months, so this shouldn’t concern I Bond investors. Not yet, at least.

We saw a similar pattern in 2019, when non-seasonally adjusted inflation fell 0.05% in November and 0.09% in December, but then rebounded higher in the next three months. That pattern was even more dramatic in 2018, when inflation fell 0.33% in November and 0.32% in December, then rebounded higher.

Here are the inflation data so far for this rate-setting period:

You can see this data going back to 2012 on my Tracking Inflation and I Bonds page.
