That is not true. This is typically how bank loans work: You make an account at a bank and deposit, say, $1000. Before 2020, the Fed would require the bank to retain something like 10% of that $1000 (just using 10% in this example, I haven't looked up what the ratio was pre-2020). So they'd deposit $100 of your cash to keep on hand and could then loan out the other $900 to those seeking a loan.

However, the Fed set that reserve ratio to 0% in 2020, which is idiotic in the long-term and also likely a main contributor several banks collapsed in 2022/2023 as the Fed started raising interest rates (I'm no economic expert by any means, so I could be wrong on the main contributing factor).

I think you're mixing up regular banks with the federal reserve, who definitely can just print money out of thin air.
