July 9, 2023

Key Takeaways:

  • Nayms has issued the world’s first crypto-denominated industry loss warranty (ILW) through the second segregated account within its marketplace.
  • The ILW provides retrocessional reinsurance protection to property reinsurers, specifically covering US named windstorm events.
  • By utilizing USD Coin (USDC) as collateral within an independently audited Ethereum smart contract, Nayms ensures enhanced transparency and efficiency in the collateralization process.

Nayms SAC Ltd., the leading crypto-native insurance marketplace, has achieved a significant milestone by issuing the world’s first crypto-denominated industry loss warranty (ILW). The ILW, facilitated through the second segregated account or ‘cell’ within Nayms’ marketplace, offers retrocessional reinsurance protection specifically for property reinsurers.

Innovative Features of the Crypto-Denominated ILW

In this groundbreaking program, Nayms provides coverage for US named windstorm events with a loss trigger above $60 billion. The ILW’s structure aligns with other industry loss warranties, but Nayms introduces innovative elements that revolutionize the traditional approach. One such innovation is the use of USD Coin (USDC) as collateral within the segregated account, which is secured through new mechanisms and concepts. These include a digital multi-signature process, offering enhanced transparency and efficiency in the collateralization process.

Dr. David Verbeeten, Chief Commercial Officer at Nayms, highlights the broad range of benefits offered by this deal. Insured parties gain access to alternative capital, while investors can earn regulated returns on their cryptocurrencies, which are not correlated to most other financial instruments. The deal exemplifies the advantages of Nayms’ business model and technology.

Prospero Re and Guy Carpenter’s Involvement

The purchaser of the ILW is Prospero Re, a Bermuda-based insurer that is wholly owned by Resolute Global Partners. Prospero Re, known for its commitment to innovation, partnered with Nayms to secure the first-ever property catastrophe reinsurance contract denominated in cryptocurrency. Notably, the ILW incorporates a loss trigger based on the advanced catastrophe modeling technology behind Resolute Global Partners’ Footprint product. This innovative ILW introduces a transparent, timely, and highly efficient way for investors to access the property catastrophe market.

The seamless placement of the ILW was facilitated by Guy Carpenter, a leading global risk and reinsurance specialist. Acting as the sole placing broker, Guy Carpenter provided guidance to both Prospero Re and Nayms throughout the placement process, ensuring a successful transaction.

The Significance of the ILW Market

The ILW market is part of the larger global property catastrophe reinsurance market, which generates over $300 billion in annual renewal premium. The introduction of the world’s first crypto-denominated ILW by Nayms opens up significant opportunities for insurers, insureds, and investors in this market. Building upon the success of this groundbreaking ILW, Nayms remains committed to reshaping the insurance industry through the deployment of emerging technologies. The company invites interested parties to explore other prospective segregated accounts within Nayms’ marketplace, which offer diverse investment opportunities and estimated returns.
