According to mainstream theory theirs should be accelerating to the stratosphere and it isn't.
Almost like interest rates are a distributional variable, not a control variable...
High interest encourages people to stop borrowing which means the rate of repayment will exceed the rate of new borrowing, which results in a decrease of the money supply. I won't deny this but you can only do this until some regions or sectors of the economy have run out of money. Then a crisis sets in and the government will do the opposite. This is why the money supply tends to go up. It is because economists haven't figured out how to do internal distribution properly, which is kind of a big deal because the wrong internal distribution can mean that all your macroeconomic theory becomes meaningless. So the go to answer is 'infinite economic growth' because that is how you can remain clueless and yet pretend that everyone benefits from even the most unfair distribution.
The amount of times economists say that "X is an internal redistribution so it is not relevant on the macro scale" is irritating.
