Wall Street Scrambles to Defuse Trump’s Credit Card Onslaught

President Donald Trump’s attack on two of the biggest ways banks make money off of credit cards has Wall Street racing to come up with an olive branch — even as they gear up for a potential fight.

While they privately fume about Trump’s recent broadsides, some executives are toying with ideas such as offering a card that would cap interest charges at 10%, according to people familiar with the matter. Others are considering promotional offers that would provide customers with temporary rate relief, the people said.
