If you are covering the OBR's fiscal risks and sustainability report and in particular its forecasts around the State Pension costs, please see the following comment form Jon Greer, head of retirement policy at Quilter:
 
Many retirees rely significantly on the State Pension to sustain their standard of living, particularly amid persistently high inflation and interest rates. Yet, while its role in safeguarding older generations is well-meaning, the long-term fiscal implications of the triple lock cannot be ignored. The Office for Budget Responsibility (OBR) has now forecast the cost of moving from an earnings-link in 2012 to the triple lock uprating mechanism is set to reach £15.5 billion annually by 2030, three times higher than its original estimate, highlighting the strain placed on public finances from fluctuating wages and inflation.
 
Despite its good intentions, the triple lock lacks a defined benchmark for pension levels and risks placing an unsustainable burden on both taxpayers and future generations. This concern was echoed by the Institute for Fiscal Studies (IFS) in its recent Pensions Review and further amplified by the Adam Smith Institute, which warned of fiscal unsustainability as early as 2036. The OBR described the UK’s fiscal position as “relatively vulnerable,” citing demographic pressures and policy reversals that amplify spending commitments.
 
In light of these realities, the government should start a formal consultation on pension uprating, coupled with a comprehensive review of the State Pension’s adequacy, to determine a fair and financially viable future path.
 
Such a review should also involve a cross-party agreement on what proportion of mean full-time earnings the State Pension ought to reflect. Once this standard is set, the uprating mechanism could then be reformed to track average earnings growth, with built-in flexibility to accommodate periods of high inflation. For instance, if earnings growth temporarily lags behind price increases, the pension could be linked to inflation until real wages recover,  at which point it would revert to its earnings-based benchmark.
 
This approach would better reflect the overall health of the economy, protect pensioners’ purchasing power, and embed a principle of intergenerational fairness. A modernised system, aligned with economic conditions and demographic shifts and is imperative for the sustainability of the state pension system.
