The UK think tank IFS warns that Chancellor Rachel Reeves plans to achieve an average annual growth of 1.0% in public sector productivity by 2028/29. If this plan fails, she will face 'significant fiscal issues.' This target exceeds the historical averages of 0.7% (2009-2019) and 0.2% (1997-2019). Failure to meet the efficiency target could put pressure on public finances ahead of the budget release in November, as tax increases are expected at that time.
