FED prints the money and generously loans it to the banks to back their swaps and speculative derivative investments.

Problem is, inflation has diluted the value of a dollar, so when a bank holds a mortgage for $100,000, and expects to make 5% compounded interest over 30 years, the buying power of each dollar (and future dollar) is deteriorating at an accelerating rate.

Now apply this to many thousand properties and business to get an idea of how fast this is imploding.
