Ofcourse this is perfect time for banks to make money and their main source of income is giving the loans and collecting the tax money which happens more when people don't have money and now people don't have money because they lost jobs, business due to covid 19 quarantine days.
Usual banks don't collect tax.
It's the tax bureaus job to collect it but banks are capable of loaning and they'll do it with or without covid. The difference is the interest rates are lower this time but I think the money that they loan is also coming from somewhere, mostly depositors money but still favorable to them and profitable to lend.
