Our chart of the week is on UK public sector pension liabilities, analysing how the net pension obligations reported in the Whole of Government Accounts 2022/23 reduced from £2,639bn on 1 April 2022 to £1,415bn on 31 March 2023. 

The Whole of Government Accounts are prepared in accordance with International Financial Reporting Standards (IFRS), with net pension obligations calculated in line with International Accounting Standard 19 (IAS19): Employee benefits.

The chart starts with opening net pension liabilities on 1 April 2022 of £2,639bn, comprising £2,539bn for unfunded schemes (including the NHS, teachers, civil services, armed forces, police and fire service schemes, among others) and a net liability of £100bn for funded schemes (principally local government schemes, but also some central government entities such as the BBC and the Bank of England, for example). The closing position on 31 March 2023 was £1,415bn, being pension liabilities of £1,419bn for unfunded schemes and a net pension asset of £4bn for funded schemes.

Service costs added £117bn to pension liabilities during 2022/23 and net interest added a further £48bn. These increases were more than offset by £1,269bn in net actuarial gains, £50bn in payments to pensioners in the unfunded pension schemes, and £70bn in other movements.

Service costs principally arise from the additional pension entitlements earned by public sector workers during the year, while net interest comprises the unwinding of the discount on pension liabilities (£40bn for unfunded schemes and £11bn for funded schemes) less investment income on assets in funded schemes (£3bn).

The net actuarial gains of £1,269bn comprises £1,357bn from changes in the assumptions underlying the value of liabilities (£1,218bn on unfunded schemes and £139bn in funded schemes) less £60bn (£59bn on unfunded schemes and £1bn on funded schemes) in experience gains and losses, less a loss of £28bn on investments. The principal assumption changes related to a change in the discount rates used to calculate pension obligations, which for the unfunded schemes increased from a real (i.e. inflation-adjusted) rate of 1.3% on 31 March 2022 to 1.7% on 31 March 2023.

The unfunded scheme liability is reduced for pensions paid on behalf of the schemes by the government. This contrasts with the funded schemes where assets are used to fund settlement of pension liabilities, resulting in no change in the net position. Other movements include £35bn in opening balance restatements relating to the NHS and former Royal Mail pension schemes and £39bn from the failure of 198 local authorities and the Northern Ireland Teachers Superannuation Scheme to report numbers to HM Treasury, less a net £4bn in other movements. 

The omission of so many local authorities, and the lack of audit assurance for many others, has led to the first ever audit opinion disclaimer by the Comptroller and Auditor General on the consolidated financial statements for the UK public sector.

Not shown in the chart is the breakdown of the £1,419bn closing balance for unfunded schemes into its constituent schemes: £535bn for NHS workers, £335bn for teachers, £222bn for civil servants, £156bn for the armed forces, £104bn for police, £30bn for pre-privatisation Royal Mail workers, £23bn for fire services, and £14bn for public sector staff in other unfunded schemes. Also not shown is the £304bn of liabilities in local government and other funded pension schemes or the related £308bn in investments in those schemes that result in a net pension fund asset of £4bn on 31 March 2023.

The recognition of a £1.3tn actuarial gain in the statement of comprehensive income and expenditure appears positive for the reported financial position of the nation by contributing to a reduction in overall net liabilities from £3.9tn to £2.4tn. However, it is important to realise that the future obligations to pay pensions to public sector employees haven’t changed – it is how those obligations are converted into current values.

Irrespective of the discount rate used, we as a nation will need to pay out very large amounts of money in public sector pensions.
