This is very confused "Internet economics" take on the issue. Money in band account that is not used is just a number. As Fed puts more money into the economy, the velocity of money decreases as the money is used less. https://fred.stlouisfed.org/series/M2V Federal Reserve can increase and decrease effective money supply as it pleases. Money supply does not determine the prices as we have learned over last two decade…
That's assuming, contrary to the motivation for loose monetary policy, that there wouldn't have been deflation without it. It's not loose money produces low velocity but loose money as a reaction to low velocity.
