The Federal Reserve raised the target federal funds rate by 0.75 percentage point for the fourth time in a row on Wednesday, marking an unprecedented pace of rate hikes.
The federal funds rate, which is set by the central bank, is the interest rate at which banks borrow and lend to one another overnight.
As the federal funds rate rises, the prime rate does, as well, and your credit card rate follows suit within one or two billing cycles.
Still, it's not the interest rate but the sticker price of the vehicle that's causing an affordability problem, McBride said.
Federal student loan rates are also fixed, so most borrowers won't be impacted immediately by a rate hike.
