Mind the Gap: A UK Microprudential Perspective on General Insurance Protection Gaps

Why It Matters

Protection gaps can amplify economic losses and strain financial stability, making insurer resilience and market availability critical for the UK economy. The PRA’s micro‑prudential stance influences both the supply of insurance and the broader effort to close these gaps.

Key Takeaways

• PRA sees protection gaps as indirect risk to insurer safety and stability
• FloodRe cut UK flood insurance from £4,400 to £1,100 (≈$5,600‑$1,400)
• Only ~7% of UK firms had dedicated cyber insurance in 2025
• PRA will consult on a 2026 captive regime to expand specialty cover
• Global pandemic business‑interruption insurance covered <1% of $4.5 trillion loss

Pulse Analysis

Protection gaps—where the economic benefit of insurance exceeds actual coverage—have become a focal point for regulators worldwide as climate events, cyber attacks, and pandemics generate losses far beyond traditional underwriting capacities. In the United States and Europe, insurers are grappling with data scarcity and pricing challenges that limit market depth, while the UK’s London Market, the world’s largest commercial reinsurance hub, faces similar pressures. The PRA’s review underscores that these gaps are not merely underwriting issues; they intersect with macro‑financial stability by influencing concentration risk, net exposures, and the ability of banks and corporates to manage their own risk portfolios.

Within the UK, the flood protection gap illustrates both progress and lingering vulnerability. The FloodRe scheme, a public‑private partnership, slashed average household flood‑insurance quotes from £4,400 to £1,100 (≈$5,600 to $1,400), yet exclusions for post‑2008 builds and multi‑unit dwellings leave millions exposed as climate‑driven inundation rises. Simultaneously, cyber risk remains starkly under‑insured: only about 7% of businesses reported dedicated cyber policies in 2025, despite an estimated annual UK cost of £14.7 billion (≈$18.7 billion). The PRA’s upcoming 2026 captive‑insurance consultation and reforms to insurance‑linked securities aim to broaden capacity for high‑frequency, low‑severity perils, encouraging bespoke solutions that traditional markets shy away from.

The broader implication for financial stability is clear: unchecked protection gaps can shift loss burdens onto public finances and the real economy, eroding confidence in the insurance sector’s ability to absorb shocks. By calibrating micro‑prudential supervision—balancing safety and soundness with proportional regulatory requirements—the PRA can foster a more resilient market that offers affordable coverage while avoiding over‑regulation that stifles innovation. Coordinated action across regulators, industry, and government, including risk‑reduction investments and public‑private risk‑sharing mechanisms, will be essential to narrow these gaps and sustain the UK’s role as a global insurance hub.
