The Treasury expects the annual pace of inflation will slow even further in the March quarter as year-earlier petrol prices roll out of the equation and the government's 'fees free' tertiary education policy comes into effect.
In its monthly economic indicator, the government's financial adviser predicts the consumers price index will rise an annual 1 per cent in the three months ended March 31, slowing from a pace of 1.6 per cent in December when it was short of most forecasts, including the Reserve Bank's.
The Treasury said measures of underlying inflation remain subdued as the impact of earlier petrol price increases drop out of the annual calculation, and as new policies including the first year of tertiary education for free keep a lid on consumer prices.
However, inflation is expected to gradually pick up over 2018 and 2019 as capacity pressures bind further and global inflation begins to normalise, it said. In its half-year economic update released in December, the Treasury forecast annual inflation of 2 per cent in the June 2018 quarter and 1.9 per cent in June 2019.
The Reserve Bank will review monetary policy this week and is expected to keep the official cash rate unchanged at 1.75 per cent. The soft December inflation print saw some economists push out their expectations for the Reserve Bank to start raising interest rates until next year.
