Sanders and AOC are planning on introducing the Loan Shark Prevention Act establishing, among other things a 15% cap on credit card interest rates.
Marketwatch has an interesting take on this that I hadn't considered, stating that this "could be the death knell for credit-card rewards programs."
I think death knell may be a bit strong and overly dramatic, but I could see significant devaluations happening across the board. I don't play the game nearly as intensively as most here, but I am a hobbyist so this piqued my interest and I'm curious how others may feel about the not-yet-proposed legislation and the effects it could (in theory) have on rewards programs.
Personally, I doubt the bill will pass in it's entirety (too many big bank lobbyists) but I wouldn't be surprised if some portion of it (namely, stricter regulations on loan sharks) did.
