Money creation can only happen through debt. Debt is a loan by a bank. The more dollars in loans, the more interest receipts generated by the banks. This type of money expansion can happen forever. It does not create a disequilibrium in the market, it just redistributes wealth from the working class to the money monopolists.
Many nations use the dollar as a reserve for their currency .
Bretton Woods established the dollar as the base for exchange rate equilibrium. Although this system is not presently used, many central banks still keep large amounts of U.S. dollars to help regulate their currency. Most of this money is idle, which puts no pressure on inflation. If this money was ever put into circulation inflation would be enormous. At present, the need to stabilize other country's currency by U.S. dollar intervention has caused deportation of inflation.
