A £2.2tn fall within the valuation of UK family wealth following a technique change by the nation’s statistics company was based mostly on a “essentially flawed” evaluation of pension wealth, in response to a number one think-tank.
The Institute for Fiscal Research on Friday accused the Workplace for Nationwide Statistics of “jumbled financial reasoning” after an adjustment by the company final 12 months knocked one-third off estimates of British family personal pension wealth between 2018 and 2020 in a single day.
The think-tank’s report is the newest setback for the ONS, which final week postponed the discharge of commerce information after figuring out an error and has come beneath fireplace from politicians and the Financial institution of England for long-running issues with a key survey on the labour market.
In December, the ONS made a number of adjustments to the way it values pensions as a part of its official estimates of family wealth.
The most important change was to maneuver away from the usage of market rates of interest to worth future pension advantages and in direction of better use of a rate-based on predicted financial development, often known as the superannuation contributions adjusted for previous expertise (Scape) price.
The company’s change in methodology was “essentially flawed” as a result of Scape was not in any significant sense a price of curiosity and didn’t replicate the true worth of a pension’s advantages, the IFS stated in its report.
The change minimize the ONS estimate of personal pension wealth from £6.4tn to £4.2tn, equal to a 14 per cent discount in complete family wealth, the IFS added.
It adopted a suggestion from the Authorities Actuary’s Division to “minimise undue volatility” within the worth ascribed to outlined profit pensions, which promise assured pensions based mostly on wage and size of service.
Nevertheless, the IFS stated the “misguided” valuation method was “a mistake, making an already flawed methodology considerably worse”.

A collapse in responses to the ONS labour power survey, which isn’t anticipated to get replaced till at the very least 2026, has left the BoE and ministers with out dependable information on employment for nearly 18 months.
It additionally triggered the Workplace for Statistics Regulation, the regulatory arm of the UK Statistics Authority, late final 12 months to warn that 14 related information units might not be categorised as “official statistics”.
The company has began utilizing Scape — now set at client worth inflation plus 1.7 per cent a 12 months — to worth the post-retirement section of a pension, having beforehand used a market-based annuity price.
Beforehand Scape, which is utilized by the federal government to calculate the price of offering public sector pensions, was used to worth outlined profit pension guarantees just for these not but retired.
The IFS added that the ONS had not revised historic information to replicate errors it had recognized, which means official estimates of DB pension wealth between April 2010 and March 2020 “needs to be thought to be unreliable”.
However the think-tank welcomed two different adjustments the company made to the way in which it values pensions in December, one to account for inflation earlier than a employee retires and the second to extra precisely replicate retirement age.
The ONS stated in an announcement that any technique should make “broad assumptions” about future financial development. “We sought recommendation from a variety of consultants and customers earlier than finalising the strategy used. We outlined these choices on the time of publication,” it added.
