The catastrophe bond market is entering the 2026 Atlantic hurricane season at a record size. Outstanding cat bond and insurance-linked securities (ILS) risk capital stood at $69.9 billion at the end of May, with year-to-date issuance of about $15.5 billion already on the books before the official June 1 start of hurricane season, according to data tracked by industry source Artemis.
Sponsors rushed deals to investors throughout May, and pricing has continued to soften as capital chases an asset class that pays high-single-digit spreads over Treasury bills with returns largely uncorrelated to broader credit and equity markets. The market backdrop matters more than usual this year: NOAA’s Climate Prediction Center released its 2026 outlook on May 21 calling for a below-normal season, with 8 to 14 named storms, 3 to 6 hurricanes, and 1 to 3 major hurricanes at 70% confidence, driven by an expected El Niño during the August-October peak.
The numbers behind the record
Several data points frame how stretched the cat bond market has become going into peak peril season:
- $69.9 billion outstanding — total catastrophe bond and ILS risk capital on issue, per Artemis’ market dashboard.
- $15.5 billion issued YTD — already through the first five months of 2026, with the bulk of US wind exposure traditionally placed by end of May.
- Florida property cat bonds: $3.2 billion YTD from 12 sponsors, per a Guy Carpenter analysis cited by Artemis on May 28 — pricing came in below 2025 comparables.
- Traditional reinsurance pricing -20% at the June 1 Florida renewal versus 2025, per a KBW research note on May 29 — though analysts call current pricing “still adequate” for capital providers.
The combination — record cat bond capacity, softer reinsurance, and a below-normal NOAA forecast — has compressed risk premia on the new deals priced this month.
Five deals tell the story
| Sponsor | Deal | Size | Peril | Notes |
|---|---|---|---|---|
| California Earthquake Authority | Sutter Re 2026-1 | $400M | California EQ | Upsized from $300M target |
| Palomar Insurance Holdings | EQ tower (cat bond layer) | $1.28B | Earthquake | Part of $3.92B multi-year tower |
| Oak Global (debut) | Quercian Re 2026-1 | $150M | Retrocession | 100% upsize; priced below guidance |
| Government of Jamaica / World Bank IBRD | CAR Jamaica 2026 | $200M | Tropical cyclone (parametric) | Sovereign deal via IBRD |
| Heritage Insurance | $2.2B reinsurance tower (renewal) | $2.2B | FL property | Multi-year, “substantial cost savings” |
The CEA’s $400 million Sutter Re 2026-1 upsizing is notable: it priced through guidance and was lifted by a third over its initial target, a familiar pattern this year. Oak Global’s debut Quercian Re 2026-1 took $150 million on a retrocessional basis (reinsurance for reinsurers), doubling its initial $75 million target — the kind of execution that signals an oversubscribed bid.
The Jamaica deal is structurally different: a parametric cat bond intermediated by the World Bank’s IBRD Capital-at-Risk Notes program, where payout is triggered by an objective metric like minimum central pressure rather than measured insured losses. Parametric structures pay quickly, which matters for sovereign disaster response.
Why investors keep bidding
The bid is structural. Pension funds, sovereign wealth allocators, and dedicated ILS funds have grown steadily as a buyer base because cat bond returns sit largely outside the global macro and credit cycle — what an asset allocator calls “low correlation.”
Yields are the other half of the story. With the 3-month Treasury bill near the federal funds effective rate of 3.62% as of May 28 and risk premiums on diversified cat bond portfolios historically running 4-7 percentage points over T-bills, the all-in coupon on a typical seasoned cat bond comfortably clears mid-single-digit yields available in investment-grade corporate credit, while bringing a different risk profile.
That math is part of why fee income is rising at the platforms that run third-party ILS capital. Aspen Insurance reported on May 29 that its capital markets unit grew Q1 fee income by 11% to $50.6 million, with a focus on third-party reinsurance vehicles.
What could go wrong
Cat bonds are not riskless — that’s the point. When a triggering event occurs, principal can be partially or fully written down to cover insured losses. NOAA’s below-normal forecast is a probability, not a guarantee: 2025’s season similarly started with a modest outlook and was reshaped by a small number of high-intensity landfalls. A single Florida major hurricane can trigger losses across multiple aggregate bonds.
The El Niño signal NOAA cites — a 98% probability for August through October — tends to suppress Atlantic activity via stronger vertical wind shear, but does not preclude individual intense storms. Investors holding aggregate-trigger bonds, which can accumulate losses across multiple events, carry tail exposure that does not show up in any single-event probability.
The other risk is more mundane: spread compression. With pricing softening 20% at June 1 renewals and 2026 cat bond issuance pricing through guidance, returns to new ILS capital are coming down even before a single storm rotates off the African coast.
Outlook
Expect issuance to continue through June as sponsors finalize hurricane-season placements, then taper into Q3. Watch for the first Florida wind event of the season as the market test of how tight pricing has become. And watch sovereign and multilateral issuers — Jamaica’s deal this week is part of a broader trend of cat bond use by emerging-market governments and the World Bank to pre-fund disaster response. The structural growth story of ILS as an asset class is intact; whether 2026’s vintage delivers the returns its coupons promise depends, as always, on the weather.
