Annual inflation rose to 2.2 per cent in the first three months of the year, well above the central bank's forecast of 1.5 per cent, but Reserve Bank governor Graeme Wheeler looked through that jump in case it was only temporary when keeping the official cash rate unchanged at 1.75 per cent last month.
