This is the first I've heard, but it doesn't surprise me. I'm a hardcore CC churner and banks have tighten up so much on the lending side since Covid-19 started. The problem is banks have still not been able to price in their defaults and risk assessments due to Covid-19 so most are just treading water and waiting to see what happens. They know CC defaults will be the the canary in the coal mine so they limiting themselves anyway they can when it comes to Credit cards. Cutting back on approvals, lowering limits, not doing balance transfers ect.
