The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.1 percent in September on a seasonally adjusted basis after rising 0.2 percent in August, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index rose 2.3 percent before seasonal adjustment.

The shelter index continued to rise and accounted for over half of the seasonally adjusted monthly increase in the all items index. The energy index declined 0.5 percent in September after rising in August. The food index was unchanged in September, as an increase in the index for food away from home offset a decline in the food at home index.

The index for all items less food and energy rose 0.1 percent in September, the same increase as in August. The shelter index increased 0.2 percent, and the indexes for apparel, motor vehicle insurance, recreation, and airline fares also rose. The medical care index increased as well, though its components were mixed. The index for used cars and trucks, which fell sharply, and the new vehicles index were among the indexes that declined in September.

The all items index rose 2.3 percent for the 12 months ending September, a smaller increase than the 2.7-percent increase for the 12 months ending August. The energy index rose 4.8 percent over the last year, a notably smaller increase than the 10.2-percent increase for the 12 month period ending August. The index for all items less food and energy rose 2.2 percent for the 12 months ending September and the food index increased 1.4 percent; these were both the same rate of increase as for the 12 months ending August.

The mortgage market around this release

This original analysis is separate from the source article. It compares observed benchmarks around ; historical averages and yields are not current mortgage offers.

Read consumer inflation on a consistent basis

The Consumer Price Index measures changes in prices paid by urban consumers for a basket of goods and services. Check the index, reference month and seasonal adjustment before comparing figures. A monthly change and a twelve-month change describe different periods; the all-items index and the measure excluding food and energy cover different baskets. Consumer inflation informs the wider policy discussion, but the benchmark comparison below does not isolate this release from other information arriving during the month. BLS Consumer Price Index.

What that benchmark difference would mean for a $300,000 loan

At the publication reference$1,592.18/month

4.90% · Oct 11, 2018

At the later reference$1,599.48/month

4.94% · Nov 8, 2018

The illustrative principal-and-interest payment is $7.30 higher per month. This holds the loan amount and term constant to show the arithmetic effect of the benchmark difference.

Assumptions: two separate hypothetical $300,000 loans, each fully amortizing over 30 years with 360 monthly payments and its stated fixed interest rate. Excludes points, lender fees, taxes, insurance, association charges and other costs. PMMS is a national average, not an APR or a personalized rate offer. These are not two payments on one existing loan.

Sources, historical coverage and calculation limits

The 30-day comparisons use calendar days. Each cell selects the last published observation on or before its target; no rates are synthesized for missing dates. Gaps greater than seven days for daily Treasury data or fourteen days for weekly mortgage data are marked unavailable. Forward comparisons require the date to have arrived and source coverage to extend through it.

Historical files may contain revisions and do not reconstruct precisely what every market participant knew at the time. Freddie Mac changed its PMMS collection methodology in November 2022. Cross-period comparisons should account for that change. These windows include other news and cannot establish causation or forecast the next rate move.
