See this is a perfect example of how banks use sleight of hand with language to confuse us. We're talking about the money multiplier effect and you use this ratio that makes it look like this system is completely reasonable. In fact I didn't believe it at first, so I looked it up. When I realized it's accurate my whole banking paradigm began to shift.... Until I remembered this statement from an economist "deposits don't create loans - loans create deposits."
That's when I realized the ratio you threw out measures deposit liabilities and not the reserves we had been discussing. Of course that ratio is going to be high, when a loan is issued to purchase something, the seller will eventually deposit the money into their bank. If the buyer and seller use the same bank the LTD ratio for that transaction is 100%. That ratio has nothing to do with what we were discussing.
Then I started wondering what kind of loans aren't eventually deposited into a bank. I'd appreciate any examples you guys can give. The only type I can think of are maybe foreign purchases, that get deposited in a foreign bank, and loans to hedge funds that are gambled in the stock market. If 30% of the loans banks make are going to the stock market, I'm actually pretty terrified.
