I went in search of the capital requirements, just to get a feel for what limits do exist--since they're no longer directly connected to deposits. I found them: https://www.ecfr.gov/current/title-12/chapter-I/part-3/subpa...

But then my eyes glazed over and I remembered that I am not proficient in this language. Presumably the following requirements do place some limits on how much money they can have created?

> A common equity tier 1 capital ratio of 4.5 percent.

> A tier 1 capital ratio of 6 percent.

> A total capital ratio of 8 percent.

> A leverage ratio of 4 percent.
