The Office for Budget Responsibility (OBR) has warned that state pension spending in the UK could nearly double as a share of the economy over the next 50 years, driven by the triple lock policy. According to the OBR's latest fiscal risks report, spending on the state pension is projected to rise from 4.8% of GDP in the last fiscal year to 8.6% by 2075-76 if the triple lock remains in place.
Triple Lock Mechanism and Cost Pressures
The triple lock, introduced in 2010 by the coalition government, guarantees that the state pension increases annually by the highest of average earnings growth, inflation, or 2.5%. The new state pension currently stands at £12,548 per year, having risen by 55% since its introduction in 2016. The policy has been a key factor in the rising cost of the state pension, which currently costs taxpayers around 5% of GDP.
The OBR report also cites increasing life expectancy as a contributing factor to the projected cost increase. As people live longer, the total number of years for which pensions are paid rises, adding further pressure to public finances.
Expert and Charity Reactions
David Brooks, a director at financial services consultancy Broadstone, questioned the universal nature of pension increases. He said: "At a time when many pensioners are asset rich and younger generations face significant barriers to wealth accumulation, it is reasonable to ask whether universal increases remain the most effective use of public resources. The real policy question is not whether pensioners should be protected from poverty – they absolutely should be. It is whether taxpayer support should be targeted more effectively towards those who genuinely need it, rather than continuing to provide identical increases across the entire pensioner population regardless of income or wealth."
However, Caroline Abrahams, charity director at Age UK, defended the triple lock. She said: "Politicians and think tanks seem to be queuing up to call for the triple lock to be scrapped. The triple lock continues to play a vital role in buoying up pensioner incomes, especially if you haven’t got much money coming in and are struggling to afford bills and constantly cutting back on the basics. We accept that the triple lock may not be needed forever, but it is certainly needed today. More older people would be pushed into poverty without it."
Government Response
A Treasury spokesman reaffirmed the government's commitment to the triple lock, stating: "We are committed to supporting pensioners and giving them the dignity and security they deserve in retirement. The chancellor committed to the triple lock, as stated in the manifesto this Government was elected on, benefiting over 12 million pensioners. We recognise the long-term economic realities highlighted by the OBR, which is why we remain committed to our non-negotiable fiscal rules that ensure economic stability and sustainable public finances."
