Where do they make money?

Answer 1

Money created by manufacturing a new monetary unit, such as paper currency or metal coins, is most often a responsibility of a government's treasury. In modern economies, relatively little of the money supply is in currency (i.e. coins and banknotes); most is created by lending or quantitative easing (see below) using fractional reserve banking. In the U.S., only about 2% to 3% of the total money supply consists of physical Coins and Paper Money. It is usually printed at a mint.
