Yes, but it appears that the banks are not over levered like they were during the housing crisis. They will take a hit, but presumably will not need bailing out.
Banks weren't over levered back then either because all the mortgages went straight into CDOs held by other people/institutions.
The problem was that nobody trusted each other because Lehman could just fail. So they stopped lending to each other (like the daily loans they give each other). Trust evaporated and the whole system stopped dead in its tracks.
Leverage is not the only thing that matters...

The rate of growth in this sector is "1. move so fast legislators can't keep up; 2. keep going until you hit a limit, then find a way to hack around that limit; 3. GOTO 2".
