Central banks operate from the disutility channel

The way government fiat banks operate is simple.  When they try to match rates with economic yields, they do fine. When they suppress rates they raise the cost of financial services which then must bridge the gap between real yields and money rates.

This issue comes up repeatedly.  Real economic yields come from tractors and trucks and things.  They stick, fake rates from the fiat banker are intermediated, at great cost. Most fiat bankers and their government owners get caught in moral hazards, hence the reason we like democracy.
