The Trillion-Pound Question: UK Investment Assets

Determining exactly how much money exists within the UK investment system is a fundamental prerequisite for any government seeking to unlock capital for productive growth. Despite the UK possessing the second-largest pool of retirement capital in the OECD, business investment remains alarmingly low, indicating a severe failure in capital allocation. To assess the available capital, NCC analysed the "stocks" (accumulated pools of capital) and "flows" (activities moving money) within the system, treating it as a complex adaptive system. A major hurdle in this analysis is the extremely poor quality of official data, with varying estimates provided by the ONS, the Pension Protection Fund (PPF), and The Pensions Regulator (TPR).

By relying on the ONS Financial Survey of Pension Schemes (FSPS)—which accurately captures portfolio rebalancing, leverage, derivatives, and repo—this report establishes that total assets in occupational pensions stand at £2,209 billion as of early 2024.

  • Private sector DB and Hybrid pensions remain the largest pool, but their market value crashed dramatically by 36% (a £653 billion loss) from a peak of £1,834 billion in Q4 2021 to £1,181 billion in Q1 2024.

  • This massive destruction of capital was primarily caused by the Liability Driven Investment (LDI) crisis and the repricing of fixed-income assets in a higher interest rate environment.

  • Central government schemes and the Local Government Pension Scheme (LGPS) manage £547 billion; because they remained open and avoided LDI strategies, they maintained stable growth with higher allocations to equities and private markets.

  • The Defined Contribution (DC) market, fueled by auto-enrolment, is a rapidly growing pool currently holding £288 billion in private DC and £193 billion in DC Master Trusts.

The report dispels the myth that all existing asset stocks can be easily repurposed; a significant portion of these assets is strictly "locked-up" for specific purposes like annuities. The regulatory agenda's obsession with "safetyism" has inadvertently built massive systemic risk while severely hampering the institutional ability to channel capital into the real UK economy. Policymakers must rely on accurate data and acknowledge these structural realities before attempting to mandate new investment flows into diverse asset classes.
