State pensions in Britain rely on the Triple Lock. Each year, the UK state pension is guaranteed to rise by the highest of three numbers: inflation, average wage growth, or 2.5%. First introduced under the Coalition Government, it has been applied since – besides a temporary suspension in 2022/23 due to anomalous distortions to average earnings from the COVID-19 pandemic. The Triple lock aims to protect the value of the State Pension by providing pensioner security from inflation and allowing pensioners to maintain rising living standards. However, the system is fundamentally unsustainable as it is both highly unpredictable and unaffordable. Politicians remain committed to an unviable, exorbitant system – shifting cost onto us as the younger generation.
Firstly, it has become a significant source of fiscal risk due to the phenomenon of a “ratchet effect.” This refers to a variable of the three triple lock indicators experiencing a permanent, one-way pension rise. In the occurrence of an economic shock, a spike to one of the three metrics enables a lock at a higher baseline that cannot be reversed. Its ratchet effect means it cannot be reversed once economic conditions normalise – resulting in an elevated State Pension value. Effectively, the State pension can trigger extreme baselines from periods of economic volatility – with future pension increases calculated from this new baseline. Therefore, the Triple Lock fuels inequality for working-age taxpayers as wages lag behind inflation, creating higher and greater unpredictability in Government spending. Projected costs are roughly three times expected than the original £5.2 billion annual cost, with estimates exceeding over £15.5 Billion per year by 2030 (Office for Budget Responsability, 2026). In short, funding pensions continues to ratchet upwards whilst working incomes face periods of decline – squeezing working age taxpayers of their income.
As the triple lock enables pension increases whilst outpacing wage increases, the upwards compounding of the lock means that not only is public spending highly unpredictable – it is also very expensive in the long run. According to the Institute for Fiscal Studies, the UK state pension triple lock is projected to drive total state pension spending up to 7.7% of GDP by the early 2070s (Jonathan Cribb, 2023). For context, it is currently at 5%. Whilst UK wage growth remains stagnant, younger workers are trapped in an economy that has several stationary, yet imperative issues: crippling student debts, surging unemployment across an exceptionally competitive job market as well as extraordinary housing prices. In addition, as our population Is ageing, the triple lock facilitates a heavier burden on working-age taxpayers – continuing to increase as the ratio of workers to retirees is shrinking (Office for National Statistics, 2026). Besides, fewer taxpayers are forced to support a larger pool of pensioners for longer retirement periods. Without Government Policy which considers the relative living standards of young taxpayers, the triple lock is undoubtedly an unsustainable practice and must be met with fiscal reform to ensure a more stable future.
A possible alternative to the system may be through the introduction of a double lock – removing the 2.5% floor guarantee. Rising pension value would match the highest metric between inflation or average wage growth. Although it leaves pensions protected, a double lock wouldn’t eliminate the issue of the ratchet. The problem is that pensioners would still get the better of wage growth or inflation, which would push pensions upwards at the benefit of temporary economic spikes. As a result, the most favourable solution to the triple lock comes by introducing a “smooth earnings link” which aims to keep the State Pension Value at a stable rate in relation to average earnings. If pension growth increases at an unusual rate, future increases beyond that are adjusted to the rates of its relationships with wage growth (Torsten Bell, Laura Gardiner, 2020). Not only does this eliminate the ratchet effect where pensioners can benefit from harsh economic spikes, it allows for a more predictable Government spending plan which forecasts based on wage growth. Nevertheless, a smooth earning links system removes higher pension increases per year – making a possible transition to this system as categorically unattractive to older voters with the removal of a guaranteed pension increase. Do we begin to prioritise future economic sustainability or carry on giving exceedingly high protection for pensioners?
Establishing that the system indubitably favours the older generation, the Triple Lock is highly favoured by Politicians. Older generations have higher turn outs of votes than younger demographics of voters. So, any outright suggestion to scrap or even adjust the system would place major electoral risk on a candidate. As a result, Political parties maintain a greater share of votes by remaining committed to the Triple Lock regardless of its economic controversies. Prime Minister Andy Burnham and the current labour government look to maintain the Triple lock as an effort to abide to the 2024 manifesto of Sir Keir Starmer (Jess Sharp, Sky News, 2026). However, in the 2025-26 tax year, Government state pension spending totalled over £146.1 Billion. With growing concerns over defence spending (£65.4 Billion) it seems that fiscal reform to the Triple lock system seems required (Office for Budget Responsability, 2026). Crucially, the system was introduced to provide a safety net for pensioners from rising living standards. However, relative pensioner poverty since 2011 has risen from 13% to 16-18.6% (Work and Pensions Committee, 2025).
Overall, the Triple Lock is not a viable system. It contributes to an intergenerational inequality that protects pensioners but ignores any similar guarantee for young workers. Our concerns over an excessively generous system must be formally recognised as it is a legitimate issue. Whilst young workers persist on financing a momentous fiscal burden – politicians place electoral safety over prospective economic instability. We must continue to address this issue; we must break the Triple Lock.
