In a lot of jurisdictions there's no minimum reserve requirement anymore, in cash. It's not really a problem, because at the big bank level money on paper is barely real. If they need more, they can almost just ask. They do have to have a certain minimum amount of capital, though, which can take a number of forms.

I mixed up my exact terms a bit earlier, sorry about that. I'm not a professional macroeconomist, I only know enough to know they're not completely full of shit.

we are experiencing greater and greater asset bubbles and at no point in world history were things actually different.

I'm not sure what you mean by this. If things aren't any different from before, how can we have bigger and bigger asset bubbles? I don't know that we do, really. The niche for bear investors is very full, if something's overvalued by the whole market you and me won't know either.
