When Does the Prime Rate Change: FOMC Dates and Your Loans

The prime rate changes only when the Federal Reserve moves the federal funds rate, and that happens at one of eight scheduled Federal Open Market Committee meetings each year. After the January 2026 FOMC meeting, the federal funds target range sits at 3.5% to 3.75%, which puts the prime rate at 6.75%.¹ Most major banks update their published prime rate within a day of the announcement, and borrowers with variable-rate credit cards or home equity lines usually see the new rate within one to two billing cycles.

The 2026 FOMC Meeting Dates

The FOMC holds eight regularly scheduled two-day meetings a year, and the calendar is published well ahead of time.² Outside of a rare emergency session, these are the only dates when the prime rate can move:

January 27–28: completed, rates held at 3.5%–3.75%¹
March 17–18*
April 28–29
June 16–17*
July 28–29
September 15–16*
October 27–28
December 8–9*

The starred meetings also release the Summary of Economic Projections, the chart often called the “dot plot,” where each committee member marks where they expect rates to end the year.² Markets watch those four meetings most closely, and rate moves are somewhat more likely at them, though the committee can act at any session. Each meeting ends with a public statement and a press conference from the Fed Chair.

Emergency meetings outside the normal calendar are possible when a sudden shock calls for a fast response. They are rare but not hypothetical; the committee held several unscheduled sessions in the early months of the COVID-19 pandemic.

Why Only FOMC Meetings Move the Prime Rate

The prime rate follows a fixed formula: the top of the federal funds target range plus 3 percentage points. That 300-basis-point spread has held for decades, so when the Fed cuts or raises by a quarter point, the prime rate moves by the same quarter point the same day or the next morning.

Because of that formula, the prime rate never drifts on its own. It does not shift with market sentiment, and no bank adjusts it independently. Every change traces back to an FOMC vote. If the committee holds, the prime rate holds, regardless of what else is happening in the economy. That is why the FOMC calendar, not the news cycle, is the thing to watch.

Checking the Odds Before a Meeting

You do not have to guess whether the Fed will move. The CME FedWatch tool translates futures market pricing into percentage probabilities for a hike, cut, or hold at each upcoming FOMC date. It draws on 30-day federal funds futures, which reflect what interest rate traders collectively expect the effective federal funds rate to average during a given month. As those futures prices move, the implied probabilities update in real time.

The tool assumes rate changes come in 25-basis-point increments and shows the odds of each outcome. An 85% probability of a quarter-point cut means traders are heavily pricing in that result. These numbers are not guarantees, but they are the clearest real-time read on market expectations available to a consumer. Checking FedWatch in the weeks before a scheduled meeting gives you a reasonable sense of whether your variable-rate payment is about to shift.

How Fast Banks Update After an FOMC Decision

Major commercial banks typically adjust their internal prime rates the same business day as an FOMC change or the following morning. The speed is partly competitive; no large bank wants to be the one still quoting yesterday’s rate.

The industry benchmark is the Wall Street Journal Prime Rate. The Journal surveys the 30 largest U.S. banks and publishes a new prime rate once at least 23 of them have updated. That threshold is usually hit within hours of a Fed announcement, so the published WSJ prime rate moves on the same day or the next. When a loan agreement references “prime” or “the prime rate” without further detail, this is almost always the figure it means.

When You Actually Feel the Change on Your Loan

How quickly a new prime rate reaches your statement depends on the loan. A change in January might not land on your budget until February or March.

Credit Cards

Most credit cards carry a variable APR calculated as prime plus a fixed margin spelled out in your cardholder agreement. When prime moves, your issuer does not have to send 45 days’ advance notice the way it would for other term changes; federal rules exempt rate changes that result from an index moving.³ The new APR usually takes effect within one to two billing cycles. If you pay in full each month, the rate change does not reach you at all.

Home Equity Lines of Credit

HELOCs are the consumer product most directly tied to prime. Most use a variable rate pegged to prime plus a margin, and adjustments flow through within roughly one to two billing cycles. For significant term changes beyond a routine index adjustment, federal rules require lenders to provide at least 15 days’ written notice before the change takes effect on a home-equity plan.⁴ A routine adjustment that just mirrors the index does not trigger that notice. HELOC balances tend to be large, so even a quarter-point move can add real dollars to a monthly payment.

Adjustable-Rate Mortgages

A common misconception: most ARMs are not tied to the prime rate. Since 2020, the standard ARM index has been the Secured Overnight Financing Rate (SOFR), which replaced LIBOR.⁵ SOFR tracks overnight Treasury repo transactions and can move independently of prime. ARM rates also reset on a set schedule written into the loan, often once a year after an initial fixed period, rather than right after every Fed meeting. If you have an ARM, check your loan documents for the specific index and adjustment dates instead of watching prime rate headlines.

Small Business and SBA 7(a) Loans

Small business owners feel prime rate moves directly through SBA 7(a) loans, the most common federally backed business loan. The SBA caps the maximum interest rate lenders can charge on variable-rate 7(a) loans using prime as the base, with the allowed spread depending on loan size:⁶

$50,000 or less: prime plus up to 6.5%
$50,001 to $250,000: prime plus up to 6.0%
$250,001 to $350,000: prime plus up to 4.5%
Over $350,000: prime plus up to 3.0%

With prime at 6.75%, a borrower on a $400,000 7(a) loan could be paying up to 9.75%. A quarter-point Fed cut would bring that ceiling to 9.5%. SBA 504 loans work differently; their rates are pegged to 10-year Treasury yields rather than prime, so Fed decisions reach them less directly.

Why You May Not Get a Warning Letter

Federal law separates rate changes caused by an index moving from rate changes a lender imposes on its own. For open-end accounts like credit cards, lenders must give at least 45 days’ written notice before raising your rate as a penalty, for delinquency, or because of a change in account terms.⁴ That window exists so you can pay down a balance or find a better offer.

Variable-rate increases triggered by the index itself, such as prime rising after an FOMC decision, are carved out of that 45-day rule.³ The reasoning is that you already agreed to a rate tied to a public benchmark, so the public benchmark is your notice. The new rate shows up on your next statement without a warning letter in the mail. For home-equity plans, the advance notice window for non-routine term changes is 15 days, and the same carve-out applies: a HELOC rate going up because prime went up does not require advance notice.⁴

That is the practical reason to keep an eye on the FOMC calendar. By the time your statement arrives, the decision is already weeks old.
