The Swiss National Bank has kept its key interest rate target at 0.25 percent, according to AP. The SNB has set the three-month interest rate band at zero to 0.75 percent since March 2009. The central bank warned in its announcement Thursday that the Swiss franc is dangerously strong compared to the dollar and the euro. This harms Swiss exports and the tourism industry. The U.S. dollar currently stands at little more than 0.85 francs while the euro is worth just over 1.20 francs. The SNB forecast real GDP growth in Switzerland of 2 percent for the year.
