Economists believe inflation will break through the target set by the Swiss National Bank and interest rates will have to rise again.
The OECD says inflation will hit 2.4% - the bank’s target is no more than 2%. But the organisation also predicts it will fall back to 1.2% next year.
The national bank is due to announce its interest rate decision tomorrow and its widely expected a to raise rates a quarter of a percent at 2%.
But the OECD says the economy should grow by more than half a percent this year and 1.2% next.
