First off, ignore the Compound Interest Paradox as it’s been discredited on multiple occasions yet the links seems to show up in every thread that has anything to do with money or interest.
Interest is related to the supply of available loanable funds.
If there is a bunch of money the cost to borrow that money will be low (low interest) and if there is a shortage then it will be high (high interest). The law of supply and demand at work.
Saving is showing a preference for ‘future goods’ over ‘present goods’ and in order to make the money ‘work’ most people will save or invest (really the same thing, deferring present consumption) which is the source of the loanable funds.
They increase the amount of loanable funds with no underlying change in time preference on the part of the market participants when they inflate the money supply. As there is a higher quantity of loanable funds available the price to borrow these funds drop.
Everything else gets more expensive because there is more money chasing the same amount of goods and services which makes each and every dollar worth less in comparison. The more of something there the less its worth and in the case of money this means it takes more of it to equal the same amount of goods pre-inflation.
I believe that’s the article where they talk about the three phases of inflation.
This is the final phase, hyperinflation. People trade their money for anything because if they hold on to it it will become worthless. The spending doesn’t create the inflation but is the inevitable result of runaway inflationary policies. Think Zimbabwe with their million percent inflation or whatever it is.
I think since there is only a two hour difference between want satisfactions there would be no effect from artificial interest rate changes unless he happened to be in Zimbabwe and the money is devalued as fast as they can run the printing presses and buy stuff.
It means they will increase the money supply to drive down the cost of borrowing money.
I don’t know how Romania’s central bank does this but the US Fed usually just buys something in exchange for newly created money, doesn’t really matter what they buy but they mostly buy government bonds off the open market.
I would suggest reading the part about time and interest in Man, Economy and State–or the whole book for that matter as they take you from the very basics up through the complex stuff–as Rothbard does a much better job of explaining it than I do.
