The public sector pension discount rate is the interest rate which the Government uses to calculate how much employees and employers together need to pay for their pensions. For at least the last ten years, it has been 3.5% p.a. over inflation (in practice, RPI). Now it is to be 3% p.a. over CPI (the Government’s preferred measure of inflation), even though average real GDP growth in the UK over the past twenty and forty years has been about 2% p.a.. This full percentage point over historic growth is sleight of hand, but not my main complaint.
My complaint is this. Public sector workers are now almost the only section of the workforce who get, and will continue to get, defined benefit pensions. They are by far the best type of pension, and the defined contribution alternative, will, in my opinion, bring huge disappointment, anger, poverty and taxpayer-burden in the coming decades. But public sector workers do not just get something which private sector workers cannot, they also get an enormous and hidden subsidy – and this comes from the discount rate being artificially higher than that available to us – the general public. Although we cannot directly buy CPI-linked Government bonds, if we could they would yield about 1.5% p.a. Although the difference between 1.5% p.a. and 3% p.a. (the newly announced rate) may not seem much, it translates to paying about 40% of salary every year for a good defined pension scheme for the private sector investing at 1.5%p.a., compared to about 25% p.a. for the public sector, using the artificial 3% p.a. This c. £15bn p.a. hidden subsidy to public sector workers is paid for by all taxpayers both now and in the future. The Chancellor, who understands the arguments and the maths very well indeed, has thrown away a golden opportunity to demonstrate that he can see-off entrenched interests by applying sound principles of transparency and fairness. Instead he has opted for political expediency.
