Fed Continues Tightening After the September Rate Hike: What It Costs

The Federal Reserve raised the target range for the federal funds rate by a quarter of a percentage point to 3.75%–4.00% on Sep 16, 2026 — its first rate increase since July 2023 — and signaled the tightening cycle is not over. The Federal Open Market Committee approved the move by a unanimous 12–0 vote [1]. Federal Reserve Chairman Kevin Warsh characterized the U.S. economy as expanding at a solid pace, with the unemployment rate “little changed” and productivity growth strong — but described inflation as “too high and has been for too long” [1].

The move landed after the Fed held its policy rate at 3.50%–3.75% for most of 2026. At its June meeting the Committee held steady but raised its median year-end rate projection to 3.8% from 3.4% in March and removed language pointing to further rate cuts; it held again in July, and at the August Jackson Hole symposium Warsh said financial conditions could not be described as restrictive — hardening market expectations of a September increase [1]. By September 16, the Committee judged that its standard for holding rates — clear, sufficiently fast progress toward the inflation objective — had not been met [1].

More tightening appears likely. The Fed’s updated Summary of Economic Projections revised the median federal funds rate upward across every year through 2029 relative to its June projections: to 4.1% from 3.8% for the end of 2026, and to 3.9% from 3.4% for 2028. The inflation and growth projections moved only modestly by comparison: the Fed now projects Personal Consumption Expenditures inflation at 3.7% for 2026 versus 3.6% in June, and real GDP growth at 2.3% versus 2.2%, while its unemployment projection for 2026 fell to 4.1% from 4.3% [1]. Separately, the Fed’s Board approved a matching quarter-point increase in the primary credit rate — what the twelve Reserve Banks charge depository institutions for short-term backup funding — from 3.75% to 4.00%, with the secondary credit rate rising to 4.50% under its formula [3].

Where the pain actually lands

Higher revolving-credit costs are the point of a rate increase, and households are carrying more of that debt. The New York Fed’s Consumer Credit Panel shows credit card balances rising 4.5% year over year — up $54 billion — to $1.263 trillion in the second quarter of 2026, from $1.209 trillion a year earlier [1]. Balances rose most sharply among older age groups: up 7.8% among consumers aged 70 and over versus up 1.0% among those 18 to 29 [1]. The share of balances 90 or more days delinquent climbed from 7.6% in late 2022 to 12.8% in the first quarter of 2026 — due mostly to older, charged-off debt lingering on lenders’ books rather than a fresh wave of missed payments [1].

Mortgages are a different story. The Mortgage Bankers Association reported the average 30-year fixed mortgage rate rose to 6.97% in the week to September 16, from 6.85% the prior week — but those rates track the 10-year Treasury yield rather than the federal funds rate directly, and the 10-year yield climbed above 5% this week, a level not seen since mid-2007 [1].

The timing compounds pressures already squeezing households: gasoline averaged $4.17 a gallon in the week of September 14 — up 37.3% year over year — and headline inflation is on course for a sixth consecutive year above the Fed’s 2% target [1]. Lower-income households face the largest compounding effect, since they carry higher debt relative to income; higher-income households are generally better placed to keep spending — the “K-shaped” pattern [1]. Heading into the holidays, that matters: 41% of shoppers expect credit cards to be among their most-used payment methods this holiday season, and 26% expect to put a greater share of purchases on credit than last year — a group that skews toward incomes above $100,000 [1].

Terms

• Federal funds rate: the overnight interest rate banks charge each other; the Fed’s primary lever for influencing borrowing costs across the economy.

• Summary of Economic Projections: the Fed’s quarterly release of policymakers’ forecasts for rates, inflation, unemployment and growth — the so-called “dot plot.”
• Revolving credit: borrowing that can be used and repaid repeatedly, chiefly credit cards.
• PCE inflation: price growth measured by the Personal Consumption Expenditures index, the Fed’s preferred inflation gauge.
