When the Fed raises or lowers short-term interest rates, the impact doesn't ripple evenly through the economy. Different interest rate-related products will behave in different ways leading up to, and in response to, a Fed rate increase or decrease. Here's a look at how quickly your budget will take a hit, or benefit because of the Fed interest-rate moves.
Variable-rate credit cards typically
move in direct response to Fed interest rate action, as most are tied
to the prime rate. That gives issuers some latitude as the issuer's
policy may allow them to price your card on the highest prime rate
in effect during the preceding 45 days. In a rising rate environment
you'll feel the increase much more quickly. In a falling rate environment
you'll wait 45 days.
Fixed-rate cards don't provide
much of a safe haven in a rising rate environment because issuers
can change terms with as little as 15 days notice. That works against
you in a rising rate environment. It could, potentially, work to your
benefit as rates fall, but don't hold your breath.
Conclusion:
Variable-rate credit cards are sensitive to Fed moves, especially
when rates are rising.
