Underlying Issue:
Pension funds have spent two decades allocating to private equity (PE), private credit, and infrastructure. But as the baby boomer generation retires, pensions need liquidity to pay benefits. Selling PE stakes on the secondary market typically requires a 20–30% discount. A new solution has emerged in 2025–2026: pension buy-ins for private assets. A pension fund pays an insurance company a single premium; the insurer takes ownership of the PE portfolio and assumes the obligation to pay the pension’s future benefits. In return, the pension fund is off the hook. The UK’s Pension Protection Fund completed a £2.5 billion buy-in of a PE-heavy portfolio in February 2026; Canadian pension OTPP is exploring a similar transaction. The underlying issue is that insurers can hold illiquid assets longer than pensions because insurance liabilities are even longer-dated (30–50 years). This creates an arbitrage: the insurer buys the PE portfolio at a 10–15% discount to NAV (better than secondary market), locks in the carry, and earns the spread between PE returns (12–15%) and the cost of annuitizing benefits (5–6%).

Analysis:
The mechanics are complex but transformative. A typical pension buy-in for public assets is a straightforward longevity hedge. For private assets, the insurer must take legal title to hundreds of limited partnership interests, often with remaining lock-up periods of 5–10 years. The insurer must also manage capital calls (if the PE funds have unfunded commitments) and distribution waterfalls. Specialist insurers like Legal & General’s private asset unit and Canada’s Brookfield Annuity have built teams of PE legal experts to handle this. The pricing model: the insurer offers the pension a “buy-in price” equal to the present value of future benefits minus a discount for taking the PE portfolio. That discount is typically 10–15% of NAV. The insurer then holds the PE portfolio to maturity, avoiding secondary market discounts, and earns the full return. For a £500 million portfolio, a 12.5% discount equals £62.5 million of immediate value transfer from pension to insurer—justified because the pension gets certainty and liquidity.

Critique:
Progressives have long worried that private equity lock-ups lock pension beneficiaries into high-fee, opaque structures. A buy-in that transfers that risk to insurers seems beneficial—but only if the insurer is well capitalized. The critique is that insurers are taking on private asset risk that they do not fully understand. Regulators (PRA in the UK, OSFI in Canada) currently allow insurers to hold private assets as backing for annuities with a 30% risk weight, the same as public equities. But private assets are far less liquid; in a stress scenario, an insurer might need to sell at 40% discounts. A progressive reform would require a higher risk weight (e.g., 60–80%) for private assets backing annuities. Without this, buy-ins are a regulatory arbitrage: pensions dump illiquid risk onto insurers, who hold less capital than they should.

Capitalization Perspective:
For UHNW families and institutions, the buy-in market is a direct origination opportunity. First, launch a “private asset buy-in fund” that raises capital from family offices, purchases PE portfolios from pensions at a 12–15% discount, and holds them to maturity. You earn the full PE return (12–15% IRR) on a cost basis that is 12% lower—boosting effective IRR to 15–18%. Second, reinsure the buy-ins: after an insurer takes a PE portfolio, you offer to reinsure 50% of the longevity risk in exchange for a fee (3–4% of premium). This is pure spread capture with no asset management burden. Third, invest in the insurers doing the largest buy-ins (L&G, Prudential, Brookfield). Their shares trade at 8–10x earnings; as buy-in volumes grow (projected $200 billion by 2028), multiples should expand to 12–14x. Progressive angle: structure your buy-in fund as a cooperative where a portion of the discount (e.g., 2% of NAV) is returned to the pension beneficiaries as a one-time payment, rather than captured entirely by capital. This aligns profit with stakeholder welfare.
