Hammond is aiming to cut the underlying deficit to 2% of GDP by 2020, but Samuel Tombs, chief UK economist at Pantheon Macroeconomics, said: “The Chancellor has plenty of scope to soften his austerity plans in the autumn, given that the Spring statement plans incorporated a £15.4 billion, or 0.7% of GDP, margin for error in meeting his main fiscal target. The removal of the drag on GDP growth from fiscal policy should enable the economy to gather some momentum next year, giving the monetary policy committee a freer hand to raise interest rates.”
