A lot of people are becoming unemployed. To a credit card issuer that means late payments and eventually chargeoffs. The reason banks sometimes reduce credit lights, and tighten lending standards, in a down economy is because there is more repayment risk. This reduces their exposure to bad debt.
I’m still excited for the long term of rewards cards. Thanks to the government’s money printer go brrr right now the cost of credit to banks is unbelievably low.
