How does reducing capital requirements on just new loans help much? My image of a commercial bank is that it's usually pretty much maxed out; if it has a lot of money sitting around to lend, it lends it. If the value of those loans drops, your assets-to-debt ratio drops, and you can't make new loans. If I say new loans are subject to a lower equity requirement, but the old loans are still subject to the old one, you still can't make new loans. If I say capital requirements are now 8% instead of 10%, period, you now have a bunch of unencumbered assets with which to make new loans.
Am I just way, way off in my mental model?
