The real reason for record-high credit card rates? It's not what you think.

Interest rates are coming down, but credit card rates remain stubbornly high.

The average credit card rate is 20.51%, Bankrate reports. That’s a hair below the all-time record, 20.79%, set in August.

Card rates are so high, in part, because of the Federal Reserve. The central bank raised rates dramatically in 2022 and 2023 to fight surging inflation.

But that’s not the whole reason. Credit card rates are higher now than they have ever been, including times when other interest rates were higher than they are today.

The real reason why credit card rates are so high

The hidden reason for sky-high card rates, credit experts say, is that card companies are charging record-high “margins.” That’s interest the card issuer charges above the prime lending rate.

“You can think of this as a profit margin,” said Odysseas Papadimitriou, CEO of WalletHub.

Credit card margins average 14.9%, as of August, WalletHub reports. In other words, the average cardholder pays roughly 15% in annual interest on top of the prime rate. The prime rate is, in theory, the rate lenders charge their most creditworthy customers.

Card margins have never been so high. The average margin was 13.2% in August 2020 and 10.7% in August 2015, according to WalletHub.

Much has been written about the effect of the Fed’s interest-rate campaign on card rates. But card rates are steeper now than ever before, including times when benchmark interest rates were higher than today.

For instance, in mid-2000, average credit card rates floated between 15% and 16%, according to WalletHub. That’s well below 2024 rates.

But the prime lending rate stood at 9.5% in mid-2000. Today, the prime rate is 8%.

Credit card margins have risen notably since the Great Recession

Credit card margins have risen markedly since the Great Recession, a span of years that saw the benchmark federal funds rate, set by the Fed, hover near zero.

“Over all the years of these zero-percent policies, the banks used those policies to jack up the margin between their cost for funds and how much they charge consumers,” Papadimitriou said. “That margin, over the years, has kept increasing and increasing.”

Card companies cite several legitimate reasons for raising their margins, according to industry experts.

For one thing, card issuers have to cover their costs when cardholders don’t make their payments. The credit-card delinquency rate is about 3.25%, its highest level since 2011. The rate represents overdue card balances.

“Card issuers are tacking on some additional profit margin to compensate for the fact that some cardholders won't pay them back,” said Ted Rossman, senior industry analyst at Bankrate.
