Why did banks stop lending

i know they create credit through loans. Even if someone did not pay the debt back, the banks can seize the collateral and sell it and they never lose.

Why would a bank stop lending when it’s not as though lending costs much?

Credit is really non-existent money waiting to created.

This is a very confusing topic.

but even if they did not get their money back, it’s not as though it’s a real loss to them. it’s just a number in a computer.

secured loans have collateral, and unsecured ones dont.

in the case of secured lending, on properties, if house prices fall less money is recouped from a reposession sale.

also banks can’t lend beyond their reserves, and

if people declare themselves bankrupt banks might not be able to get their loaned out funds back

The Fed pays banks a small sum, in effect, not to lend.
