The £1 Trillion Pension Pot: How Britain's Retirement Savings Are Being Deployed

Britain's pension system manages approximately £2.5 trillion in assets — one of the largest pools of institutional capital in the world. For most of its existence, a significant proportion of this capital has been invested in overseas equities and bonds, reflecting the diversification benefits of international exposure and the relatively modest investment opportunities available in the domestic private markets.

That is changing. Under sustained political pressure from successive governments, Britain's largest pension funds have committed to directing an increasing proportion of their assets into UK infrastructure, private equity, and early-stage technology companies.

The Mansion House Compact

The Mansion House Compact — a voluntary agreement between the government and the UK's largest Defined Contribution pension providers — commits the signatories to allocating at least 5% of their default funds to unlisted equities by 2030. For the sector as a whole, this implies an incremental £50 billion of domestic private market investment.

The Infrastructure Opportunity

British pension funds are well-suited to infrastructure investment. The asset class offers long-duration, inflation-linked cash flows that match pension liabilities well; domestic infrastructure reduces currency risk; and the social and economic benefits of the investments sit well with the increasingly prominent environmental, social, and governance commitments that pension trustees are required to fulfil.

The Risks

Not everyone is enthusiastic about the direction of travel. Some trustees and investment advisers have expressed concern about the liquidity implications of increasing allocations to unlisted assets, particularly in periods of market stress when defined benefit schemes may need to meet increased collateral calls.
