How the prime-to-credit-card pipeline works

When the Fed raises the federal funds target rate by 25bp, the Wall Street Journal prime rate rises by 25bp on the same day. Variable-rate credit cards indexed to prime adjust their APRs at the next billing cycle.

The Fed funds target range was 4.25-4.50% as of mid-September 2026. A 25bp hike would push it to 4.50-4.75%. The prime rate, calculated as the Fed funds upper bound plus 300bp, moves from 8.25% to 8.50%. Most major issuers index variable-rate card APRs to the prime rate published in the Wall Street Journal, so the change flows through within 30-60 days (Federal Reserve H.15, September 2026; WSJ prime rate, September 2026).

What variable-rate card holders should expect

Variable-rate card APRs rise 25bp at the next billing cycle after the Fed announcement. The exact timing depends on your card's billing cycle and issuer processing schedule.

Fixed-rate cards and promotional APRs

Most cards marketed as fixed-rate include language allowing the issuer to change the rate with 45 days notice. The marketing label can be misleading.

Under the CARD Act of 2009, issuers can raise APRs on existing balances only in limited circumstances: end of promotional period, end of card membership, or after 60 days notice for variable-rate indexes. Truly fixed-rate cards (rare in the US market) include some secured cards, some store cards, and certain credit union cards. Promotional 0% APR offers are unaffected by Fed hikes during the promo period, but the post-promo rate resets to the variable-rate card APR (CFPB CARD Act guidance, 2026).

How issuers differ on rate hike timing

Chase, Citi, Bank of America, Capital One, Discover, and Amex typically adjust variable-rate APRs within 30-45 days of a prime rate change. Smaller banks and credit unions take 60-90 days.

Subprime card issuers (Credit One, Indigo, Milestone) tend to adjust fastest because their customers carry the highest balances and the issuer has the most to gain. Store cards (Target Circle Card, Amazon Store Card, Macy's) typically follow within one billing cycle of the prime change. Cards issued by credit unions often lag the most because of manual review processes (Bankrate credit card rate tracker, September 2026; NerdWallet issuer survey, 2026).

Major card issuer APR ranges post-September 2026 hike

Average new-card APRs in Q3 2026 sit at 24.13% across all issuers, with subprime cards reaching 30-36%. The September Fed hike adds 25bp on top of these headline rates.

What happens after the hike lands on your statement

Cardholders will see the new APR on the next billing cycle statement after the Fed announcement. Most issuers send a notice 45 days before the change takes effect.

The new APR applies to new purchases immediately. For existing balances, the higher APR applies after the notice period. Cardholders can opt out of the rate change by closing the account before the effective date, but they must repay the balance under the old terms. Minimum payment calculations don't change with the APR, so cardholders who pay only the minimum will pay more in interest and take longer to clear the balance (CFPB CARD Act, 2009; Federal Reserve Regulation Z, 2026).
