Thanks a lot for your comment. You are right about the distinction between money and currency. However in economical terms we speak about the money supply and not the currency supply. Both terms are often used for each other.

The process of creating currency by bank giving out loans is also somewhat different to what you describe. A bank does not have to own €100.000 to give someone a loan of €100.000. But thats a subject for another day... :)

Exactly, it needs to own about 7 to 9% as collateral. The rest is made out of thin air. I was a bank manager and I created millions from accounts that I made out from nothing.
