What the PRA is proposing

The PRA's proposals, published on 29 April 2026, introduce enhanced requirements for life insurers that cede longevity and investment risk to offshore or special-purpose reinsurers through funded reinsurance arrangements, according to the Bank of England's announcement. The measures target three core areas: concentration risk, asset quality, and recapture planning.

Funded reinsurance works by transferring liabilities from a UK life insurer to a reinsurer, which backs those obligations with a ring-fenced portfolio of assets. If the reinsurer were to fail, the UK insurer would need to "recapture" those liabilities, bringing them back onto its own balance sheet alongside whatever assets remain in the collateral pool. The PRA's concern, stated repeatedly since its 2023 Dear CEO letter and a subsequent thematic review, is that insurers may not be adequately prepared for that scenario.

Under the new proposals, insurers would face stricter limits on the share of their annuity book that can be ceded to any single reinsurer. They would also need to demonstrate that collateral assets meet minimum quality and liquidity thresholds, and maintain detailed, regularly tested recapture plans. The PRA has opened a consultation period for industry responses.

These proposals are not a sudden intervention. The regulator flagged funded reinsurance as a supervisory priority in 2023, and the thematic review that followed identified material gaps in how some firms assessed and managed the risks involved. The April 2026 package represents the culmination of that multi-year regulatory focus.

Why funded reinsurance grew so fast

The growth of funded reinsurance is inseparable from the expansion of the UK bulk purchase annuity (BPA) market. The BPA market exceeded £50 billion in annual transaction volume in 2024, according to industry estimates, as defined benefit pension schemes rushed to lock in funding surpluses and transfer risk to insurers.

That surge in demand created a capacity problem. UK life insurers needed to write far more annuity business than their own balance sheets could comfortably support. Funded reinsurance offered a solution: by ceding a portion of newly written liabilities to global reinsurers, often domiciled in Bermuda or other offshore jurisdictions, insurers could free up capital and write more business without breaching solvency requirements.

The economics were attractive on both sides. Reinsurers gained access to long-duration, relatively predictable liabilities. UK insurers gained capacity and, in many cases, pricing advantages that allowed them to compete more aggressively for pension scheme mandates. By the mid-2020s, funded reinsurance underpinned a significant share of the market's total capacity.

But the PRA's concern is that this rapid growth has outpaced the development of risk management frameworks. Concentration in a small number of reinsurers, opaque collateral structures, and untested recapture processes all feature in the regulator's published analysis. The question is whether the system would hold together under stress.

Implications for pension scheme sponsors and trustees

For corporate pension scheme sponsors and trustee boards, the PRA's proposals matter for three practical reasons: security, pricing, and timing.

Security of annuity contracts

When a pension scheme completes a buy-in or buyout with a life insurer, the scheme's members become dependent on that insurer's ability to pay. If the insurer has ceded a large portion of the underlying risk to a reinsurer, the chain of security extends further than many trustees may realise. Stronger PRA requirements on recapture planning and collateral quality should, in principle, reduce the risk that a reinsurer failure cascades back to affect policyholder outcomes.

Trustee boards conducting due diligence on potential insurer counterparties may wish to examine how heavily each insurer relies on funded reinsurance and how its arrangements compare with the PRA's incoming standards.

Pricing effects

Tighter rules could raise the cost of funded reinsurance for insurers, either by requiring higher-quality collateral or by limiting the volume of business that can be ceded. If insurers can no longer offload risk as cheaply or as freely, that cost is likely to feed through into bulk annuity pricing. Schemes approaching the market in the next 12 to 24 months should factor in the possibility that quotes may shift as insurers adjust their models.

The effect may not be uniform. Insurers with less reliance on funded reinsurance, or those already operating within the PRA's proposed limits, could find themselves at a competitive advantage. Market dynamics may therefore shift as well as overall price levels.

Timing considerations

The consultation period introduces a window of uncertainty. Insurers may pause or slow certain transactions while they assess the impact of the new rules on their capital positions and reinsurance arrangements. For schemes with transactions in progress, or those planning to go to market imminently, the regulatory timeline becomes a relevant variable.

Equally, schemes that are not yet fully funded or have not yet begun a formal de-risking process face a different calculus. If tighter regulation ultimately makes the BPA market more secure but marginally more expensive, there is an argument for sponsors and trustees to weigh the trade-off between cost and counterparty resilience more explicitly than before.

What operators should watch next

Several developments will determine how these proposals translate into practical consequences for pension scheme stakeholders.

First, the consultation responses from insurers and reinsurers will signal how the industry intends to adapt. Significant pushback could lead to modifications in the final rules; broad acceptance would suggest the market has already been moving in the PRA's direction.

Second, the implementation timeline matters. The PRA has not yet confirmed when the new requirements would take effect. A phased approach would give insurers time to restructure arrangements; an accelerated timeline could cause short-term disruption to capacity and pricing.

Third, the competitive landscape among insurers may shift. Firms that have diversified their reinsurance panels or built stronger internal capital buffers may emerge better positioned. Trustees and their advisers will need to update their assessments of insurer strength accordingly.

Finally, the broader trajectory of the BPA market remains relevant. If transaction volumes continue at or above £50 billion per year, the pressure on insurer capacity will persist regardless of regulatory changes. The PRA's proposals do not reduce demand; they aim to ensure that the supply side is built on firmer foundations.

For sponsors and trustees navigating pension de-risking decisions, the message is straightforward. The bulk annuity market is not becoming less accessible, but the terms on which it operates are being recalibrated. Understanding the regulatory backdrop is now as important as understanding the pricing.
