Ageing population could cost Britain additional £750bn

12 April 2012

Britain is facing a pension time bomb that could cost the country £750 billion unless it raises the state retirement age above 70, the International Monetary Fund (IMF) has warned.

In a new report, the IMF has calculated that the additional pension costs needed to cover the ageing population could cause the national debt to soar from 76% of gross domestic product to as much as 135% in coming years - an additional cost of around £750 billion.


"Nearly all countries have continuously underestimated how long people will live by an average of about three years," says the IMF. "With the private sector ill-prepared for even the expected effects of ageing, it is not unreasonable to suppose that the financial burden of an unexpected increase in longevity will ultimately fall on the public sector," says Laura Kodres, spokesperson for the IMF.

This means state pension predictions may be inaccurate, leaving governments with a shortfall.

"One effective way to offset the risk is to encourage people to work longer," says Kodres. "This can be achieved by linking the retirement age to expected developments in longevity." George Osborne is considering linking the state retirement age to life expectancy but it would be hugely unpopular.
