In 1945, Finland implemented "setelinleikkaus," a policy requiring citizens to cut large banknotes in half to combat post-WWII inflation, with one half retaining value and the other becoming a government bond.- The policy was ineffective as it only targeted physical cash, a minor part of the money supply, unlike more successful reforms in other European countries like Belgium.- The article speculates that future inflation control might involve digital account freezes, a more precise but potentially controversial method.
In 1945, Finland uniquely addressed inflation by physically cutting banknotes in half, contrasting with modern methods like adjusting interest rates.
This historical approach has sparked discussions on current monetary policy, where central banks manage inflation through interest rates and open market operations.
The potential future control of digital money, possibly via central bank digital currencies, raises concerns about increased government oversight of personal finances.
