Delaying the planned increase in state pension age by seven years from 2037/39 to 2044/46 will likely cost the exchequer more than £60bn, according to Institute for Fiscal Studies (IFS).
Last week, it was reported that ministers have delayed plans to raise the state pension age to 68 amid falling life expectancy in the UK.
According to FTAdviser's sister publication, The Financial Times, there have been warnings from Tory MPs that hiking the state pension age could provoke a backlash from middle-aged voters.
It is expected that the government will no longer increase the state pension age from age 67 to 68 between 2037 and 2039, as had previously been announced in 2017.
Under current legislation, this would mean that it would instead rise between 2044 and 2046.
In a report by the IFS, it said based on evidence from previous increases, delaying the increase from 67 to 68, would mean around one in 10 people would retire at age 67 rather than 68 between 2037 and 2044.
It revealed this delay would cost the exchequer £8bn to £9bn for each year that it is delayed.
This means a seven year delay would certainly cost the government more than £50bn over the seven years, and more likely more than £60bn.
Most of this is simply due to paying the state pension for longer, the IFS said.
On the other hand, income poverty rates among 65 year olds more than doubled, rising from 10 per cent to 24 per cent, when the state pension age was raised from 65 to 66.
IFS said the government should consider what additional support should be provided to those on lower incomes, and those in poor health, in their mid-60s when the state pension age increases further.
Jonathan Cribb, an associate director of the IFS, said: “Men and women born more recently are expected to live longer than their predecessors. That in itself is a strong rationale for a gradually increasing state pension age.
“On the other hand, higher mortality rates in recent years mean that any given generation is expected to live less long now than was expected at the time of the last pension age review in 2016.
“This provides a justification for delaying the rise in the state pension age from 67 to 68 that was previously planned for the late 2030s. But to do so would cost money.”
For people born in any given year, life expectancy has fallen, particularly in the most recent set of projections by the Office for National Statistics.
For example, a man born in 1971 (and who turned 50 in 2021) is now expected to live to 83.9.
In 2016, which is the information used in the first independent review of the state pension age, ONS forecast his life expectancy at age 50 to be 85.6.
The equivalent life expectancies at age 50 for a woman born in 1971 was 88.1 back in 2016, but is now only 86.7.
These falls in life expectancy certainly provide a rationale for not increasing it as swiftly as previously intended, the IFS explained.
