After the financial crisis and currency chaos of the 1990s, the Riksbank made a drastic attempt in 1992 to maintain the value of the Swedish krona.
They panic raise the then marginal interest rate to as much as 500 percent.
That interest rate lasts only a few days but has major effects.
Various reform packages for the financial market are presented, the Riksbank's new stated target will be two per cent inflation and the current repo rate will be introduced.
23 years later, on February 18, 2015, the interest rate was lowered to −0.1 percent.
This is the first time in its history that the Riksbank has introduced a negative interest rate and made Sweden part of a club of very few countries that has ever introduced a negative interest rate.
