Inflation Begins and Ends with the Central Bank. If you are to decrease inflation, you've got to reduce the money supply. Although its a heavy handed measure. The more gentle approach would be to
raise interest rates and force the cost to borrow money to be unaffordable to most, thus reducing the availability of money to fuel inflation.
For example, if buying a new car cost $30,000 and rates are 15% on that 5/yr loan, you'll pay $713.69/month. Whereas a 5% rate would be $566.13/mo. That much extra money a couple
has to come up with per month might mean they opt not to buy that car. That in turn means less
cars from the factory. Which means less money to all the suppliers, which means everybody eventually ends up broke and unable to afford higher prices. That in turn forces companies to lower prices. And thus begins a softer downward spiral in curing inflation.
