• Bank of England proposes higher capital charges on funded reinsurance
• Capital requirements to rise to around 10% from current 2% to 4%
• UK insurer exposure estimated at £40bn and growing rapidly
• Private equity-backed reinsurers driving market expansion
• Regulators warn of systemic risk and offshore concentration
• Industry raises concerns over divergence from global standards

The regulatory arm of Bank of England has unveiled plans to tighten capital requirements on funded reinsurance deals, marking a significant intervention aimed at curbing risks in one of the fastest-growing areas of the insurance market.

Under the proposals, UK life insurers will be required to hold around 10% capital against these transactions, up sharply from the current range of approximately 2% to 4%.

The move by the Prudential Regulation Authority reflects mounting concern that existing rules underestimate the risks embedded in such arrangements.

Funded reinsurance allows insurers to transfer liabilities, often to offshore reinsurers, in exchange for upfront funding.

While the structure can improve capital efficiency, regulators are increasingly wary of the opacity and interconnectedness it introduces into the financial system.

The PRA estimates that UK insurers currently have around £40 billion of exposure to funded reinsurance, a figure expected to rise to £100 billion over the next decade.

That rapid growth has heightened concerns about concentration risk and the potential for systemic vulnerabilities to build unnoticed.

Gareth Truran, executive director at the Bank of England, said the regulator was acting pre-emptively to address the issue. “We want to act now to correct this imbalance before it grows to pose more material risks across the sector,” he said.

The regulator has previously described the current treatment of funded reinsurance as a structural anomaly that favours these transactions over other forms of risk transfer.

Officials are also concerned that the trend may be diverting investment away from assets that support the domestic economy, instead channeling capital towards offshore entities.

Much of the growth in the sector has been driven by private equity-backed reinsurers. Firms such as Apollo Global Management, KKR, CVC Capital Partners and The Carlyle Group have expanded aggressively into the market, attracted by the steady returns associated with long-term insurance liabilities.

Major UK insurers including Aviva, Legal & General and Standard Life are among those making use of such arrangements, further underlining the scale of exposure across the sector.

The UK is not alone in scrutinising these developments. Regulators in both Europe and the United States are also examining the growing links between insurers and private capital, amid concerns that risk may be migrating outside traditional regulatory perimeters.

Industry reaction has been mixed. Huw Evans, UK head of insurance at KPMG, suggested the proposals could put the UK at odds with international peers.

“The PRA has gone further than its global peers in regulating funded reinsurance,” he said, adding that insurers may question the move given broader ambitions to support growth and competitiveness.

The proposals will now enter a consultation phase, with feedback sought by the end of July. If implemented, the new rules would apply to transactions completed from October, giving firms a limited window to adjust their capital planning.

The tightening stance signals a broader shift in regulatory thinking, as authorities seek to address risks arising from increasingly complex links between insurers, private equity, and offshore financial structures before they become systemic.
