The Swiss National Bank has cut interest rates by a quarter point to zero but did not go so far as negative rates, as it battles to restrain its currency, which has surged on global trade tensions. 

It is the first time that the Alpine country, which is one of the few globally to experiment with negative rates, has an interest rate of zero as it tackles lagging inflation and a surging Swiss franc, a haven currency that investors have bought up amid US President Donald Trump’s trade war.

The cut comes after annual inflation in Switzerland dipped to minus 0.1 per cent in May, the first negative reading in four years. The appreciating Swiss franc — up 10 per cent against the dollar this year — has slashed the cost of imports, dragging down consumer prices.
