September CPI at 3.7%: what faster inflation means for households, six days later

As of 8:55 a.m. ET, Tuesday, Oct. 20, 2026

Consumer prices rose faster in September. The Consumer Price Index for All Urban Consumers (CPI-U) "increased 0.6 percent on a seasonally adjusted basis in September after rising 0.4 percent in August," the U.S. Bureau of Labor Statistics said in its Oct. 14 release. "Over the last 12 months, the all items index increased 3.7 percent before seasonal adjustment."

GROKsiNEWS.com reported the CPI figures on Oct. 15 alongside that day's wholesale price report. Here is what has changed since, and how the numbers connect to gas prices, Social Security benefits and the Federal Reserve's next meeting.

What BLS reported

BLS said the gasoline index "rose 9.1 percent in September, accounting for over half of the monthly all items increase." The energy index increased 5.2 percent over the month and 20.4 percent over the past 12 months, "due in large part to the index for gasoline rising 34.2 percent over the same period," according to the release.

The 3.7 percent annual figure was "a larger increase than the 3.4-percent increase reported for the 12 months ending in August," BLS said. The index for all items less food and energy rose 0.3 percent in September and 2.6 percent over the past 12 months.

Other household costs moved by different amounts. Over the 12 months ending in September, BLS reported that the food at home index rose 1.8 percent, food away from home 3.5 percent, shelter 3.2 percent, electricity 4.4 percent and airline fares 22.4 percent.

Gas prices since the report

Pump prices have eased but remain above year-ago levels. AAA's national average for regular gasoline was $4.2786 a gallon as of Oct. 20, down from $4.4761 a month earlier and up from $3.0361 a year earlier.

The U.S. Energy Information Administration's most recent weekly survey put the U.S. average for regular gasoline at $4.331 a gallon for the week of Oct. 12, down 2.3 cents from the week before. EIA lists Oct. 20 as its next release date.

Social Security: a 3.6% raise in 2027

The Social Security Administration announced on Oct. 14 a 3.6 percent benefit increase for 2027. "On average, Social Security retirement benefits will increase by $75 per month," the agency said.

Nearly 72 million Social Security beneficiaries will see the cost-of-living adjustment (COLA) beginning in January 2027, and increased payments to about 7.3 million people receiving Supplemental Security Income will begin on Dec. 31, 2026, according to SSA. The agency notes that some people receive both.

By law, the COLA is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). SSA says the adjustment is based on the percentage increase in the CPI-W from the third quarter of the last year a COLA was determined to the third quarter of the current year. In its September report, BLS said the CPI-W increased 3.9 percent over the last 12 months.

SSA also said the maximum amount of earnings subject to the Social Security tax will increase to $192,300, and the earnings limit for workers younger than full retirement age will increase to $25,560. People with personal my Social Security accounts can view their COLA notice online starting in late November, and those who have not enrolled in paperless notices will receive their notice by mail in December, SSA said.

Newer data: wholesale prices and retail sales

A day after the CPI report, BLS said the Producer Price Index for final demand increased 1.3 percent in September, seasonally adjusted. On an unadjusted basis, the index climbed 6.3 percent for the 12 months ended in September, "the largest 12-month increase since moving up 6.4 percent in December 2022," BLS said.

The Census Bureau's advance estimates, released the same day, put September retail and food services sales at $745.0 billion, up 0.8 percent from August. Those figures are adjusted for seasonal variation and holiday and trading-day differences, "but not for price changes," meaning they are not adjusted for inflation.

What comes next from the Fed

The Federal Reserve's meeting calendar lists the next Federal Open Market Committee meeting for Oct. 27-28, followed by Dec. 8-9.

Reuters reported on Oct. 19 that the Fed "is expected to keep rates steady at 3.75%-4.00%" at that meeting, and that "Fed officials say further hikes are likely needed and are now debating the pace and extent." The same report said Fed Chair Kevin Warsh, speaking at an International Monetary Fund meeting in Thailand, acknowledged AI investment was a "shock" to prices and demand.

In an exclusive interview with Reuters on Oct. 14, San Francisco Fed President Mary Daly said, "We are more likely than not to need additional adjustments, but the timing of those adjustments to me is something we're still deliberating." That Reuters report also said longer-term borrowing costs are even higher than the Fed's policy rate, with some, "like 7.5% mortgage rates," "putting a damper on demand in some parts of the economy."

BLS has scheduled the October CPI release for Nov. 10 at 8:30 a.m. ET.
