FERMA and WBCSD Launch 'Open Sesame' To Finance Climate‑Resilience for Insurers

Why It Matters

The Open Sesame initiative tackles two intertwined challenges: the accelerating pace of climate‑related losses and the limited capacity of traditional insurance to absorb those shocks. By providing a dedicated financing pathway for preventive measures, the program could narrow the protection gap that leaves many assets under‑insured, thereby stabilising insurers’ loss ratios and preserving market solvency. For policyholders, the shift promises lower premiums and more resilient infrastructure, while for capital markets it opens a new asset class focused on climate adaptation. Beyond the immediate insurance implications, Open Sesame signals a maturing of climate‑finance thinking, moving from reactive disaster relief toward proactive risk reduction. If the framework proves scalable, it could serve as a template for other sectors—energy, transportation, agriculture—where climate exposure is high, amplifying its impact across the broader economy.

Key Takeaways

• FERMA and WBCSD launch Open Sesame to finance climate‑resilience projects before losses occur.
• Major insurers including Allianz Commercial, Aon, Marsh, FM and Howden have pledged participation.
• Boston Consulting Group will act as secretariat, coordinating risk‑modellers, reinsurers and brokers.
• The initiative aims to shift capital from post‑disaster reconstruction to preventive investments, addressing a growing protection gap.
• First financing agreements are expected within six months, with guidelines for measuring resilience impact to be published.

Pulse Analysis

Open Sesame arrives at a pivotal moment when insurers are confronting a double‑edged pressure: rising frequency of extreme weather events and the erosion of underwriting capacity. Historically, the insurance industry has relied on reinsurance and capital markets to absorb catastrophic losses, but the scale of climate risk is stretching those buffers. By institutionalising financing for pre‑event resilience, the initiative could fundamentally alter the risk‑transfer equation, turning mitigation into a risk‑reduction lever that directly benefits insurers’ loss ratios.

The involvement of heavyweight insurers signals that the market is ready to embed climate adaptation into its core business model. If insurers begin to offer premium discounts or more favourable terms to firms that adopt Open Sesame‑approved measures, we could see a rapid uptake of resilience projects, especially in high‑risk regions. This would not only reduce claim frequency but also generate a new data set for actuarial models, improving the precision of climate risk pricing.

Looking ahead, the success of Open Sesame could catalyse a broader wave of climate‑finance products, such as resilience‑linked bonds or insurance‑linked securities that reward verified adaptation outcomes. Such instruments would attract ESG‑focused investors seeking tangible climate impact, further expanding the pool of capital available for prevention. In essence, the initiative could create a virtuous cycle: more resilient assets lower insurer risk, which lowers premiums, encouraging further investment in resilience, and ultimately narrowing the protection gap that threatens both insurers and the economies they serve.
