The Pension Fund That Secretly Allocated 3% to Crypto — and Outperformed Every Traditional Peer Fund

A group of pension trustees sits in an office somewhere in the United Kingdom that resembles every other defined-benefit pension fund office. It is quiet, methodical, and has the distinct feel of a place that takes its responsibility to manage other people’s retirement funds seriously. In October 2024, those trustees made a first for a UK pension fund: they put about £1.5 million, or 3% of the scheme’s assets, straight into Bitcoin. Not via an ETF for Bitcoin.

Not using a digital asset tracker. directly, with custody divided among five separate institutions and a rebalancing system intended to systematically take profits as prices increased. The total assets of the fund were approximately £50 million. The names of the trustees have not been made public. The plan’s name has not been made public. However, because Bitcoin had returned 76% twelve months after that allocation, what transpired next has been discussed more and more at institutional investment conferences and in publications related to the pension industry.

For comparison, during the same period, gold, the asset that pensions usually turn to for non-correlated protection against currency devaluation, returned 37%. The FTSE All-World index, which measures global equities, saw a 15% return. Even in a year when Bitcoin was the top-performing major asset class, the unnamed fund’s 3% Bitcoin position beat both by a significant margin.

UK Defined Benefit Pension Fund — Bitcoin Allocation

The implications were significant for a small defined-benefit plan with a long runway prior to buyout and a weak employer covenant. In the best-case scenario, the Bitcoin allocation could advance the fund’s buyout horizon by about two years, according to the investment consultancy Cartwright, which guided the trustees through the process. The wider portfolio impact was deemed insignificant even in more conservative stress-test scenarios. A buyout timeline that is two years off is not insignificant. That is important.

The choice was not made hastily or carelessly. According to Cartwright, the procedure entails thorough scenario modeling, extensive due diligence, and rigorous trustee training. The trustees had to convince themselves that the distribution made sense within their fiduciary framework because they are legally obligated to manage members’ retirement assets prudently.

This required addressing issues with volatility, custody, liquidity, and unfavorable outcomes. The answer to the volatility question was intriguing: the model suggested that adding 3% Bitcoin would raise overall portfolio volatility by about 2 percentage points, a manageable amount considering the asset’s asymmetric return profile. Sam Roberts, director of investment consulting at Cartwright, frequently used the term “asymmetric risk-return profile” to explain the reasoning, which is that, especially for a fund with a long enough time horizon to absorb short-term volatility, a small Bitcoin position can yield outsize gains relative to the downside it introduces.

The decision to hold Bitcoin directly instead of through exchange-traded products was well-considered and represented a specific perspective on counterparty risk. Some pension consultants started reevaluating which assets carried true zero counterparty risk when Russian government bonds were frozen after the invasion of Ukraine in 2022 and sovereign debt momentarily lost its “risk-free” status in the eyes of many institutional investors. Gold is eligible. In the model that Cartwright and its partners developed, direct Bitcoin custody also qualifies; the asset is either in custody or it is not, and there is no clearing house that can freeze, no issuer that can default, and no government whose cooperation is necessary for the value to be accessible. Since 2022, this once-fringe line of thinking has gained traction in discussions about institutional investments.

The degree to which the initial reaction to this allocation was different from its final outcomes is difficult to ignore. Early in November 2024, a number of wealth managers and pension specialists described the story as “irresponsible” and “speculative.” According to Kingsfleet director Colin Low, Bitcoin is an asset with no inherent value that pension funds should not deal with. Wiltshire Wealth’s Daniel Wiltshire described it as a lack of caution. Pension funds that misjudge volatility can jeopardize the retirement security of workers who are unable to recover losses. This is a legitimate argument made by serious people, and it is not wholly incorrect. The criticism is worthy of serious consideration. However, the data presented a different picture, at least through October 2025.

This unidentified UK scheme is not the only example of the pattern. In 2024, the State of Wisconsin Investment Board discreetly increased its exposure to spot Bitcoin ETFs, accounting for about 0.1% of its $156 billion portfolio. A similar action was taken by the State of Michigan Retirement System. Under the direction of organizations dedicated to union adoption, a number of firefighter unions in the US have started allocating to Bitcoin. Bitcoin’s appeal to defined-benefit and labor-backed funds, according to Dom Bei of Proof of Workforce, who has worked with a number of these unions, is partly philosophical—a store of value born out of the 2008 financial crisis that devastated workers more than almost any other group, being adopted by the very institutions meant to protect those workers’ long-term financial security. There is a narrative coherence that is difficult to completely refute but simple to ignore.

Whether this UK scheme’s 12-month performance will lead to wider adoption or if it will continue to be an intriguing data point in a tiny area of the institutional investment world is still genuinely unknown. There are about 500 defined-benefit trusts in the UK alone, and many of them have similar structural issues, such as long time horizons, weak employer covenants, and the requirement for assets that can grow without taking on excessive risk. The consequences for Bitcoin demand are significant if even a tiny portion of those schemes take the same course. As the institutional investment community considers this specific outcome, it appears that the trustees of the unidentified fund made a thoughtful choice that the industry is currently closely monitoring—not because they were careless, but because they were correct.
