Swedish central bank cuts key rate in surprise move

Sweden's central bank cut its benchmark interest rate to -0.35 percent in a surprise move on Thursday and expanded its asset purchase programme in a bid to reinforce tentative signs that long-stagnant consumer prices are finally picking up.

The bank said that uncertainty abroad had increased and it was difficult to assess the consequences of the situation in Greece.
