From a Bermuda Cat Bond to Your HOA Master Policy

You already know your condo insurance is up. We have covered why condo insurance rates climbed the way they did and explained what a catastrophe bond is. This post follows one dollar of catastrophe risk from a tax-neutral island to the line on your HOA budget, and then to the part you carry personally and probably have not measured.

The short version: a condo owner pays for catastrophe risk twice. Once through the HO-6 policy you buy yourself, and once through your share of the building's master policy. In the worst case a residual-market assessment hits you a third time on top of both. The capital that prices that risk is offshore and largely tax-free. The losses, when the layers run out, land on you.

The chain, one link at a time

Start at the far end, where the money sits, and walk it back to your unit.

Link 1: the catastrophe gets turned into a bond. When a hurricane or wildfire exposure is too big for an insurer to hold, part of it is sold to investors as a cat bond or related insurance-linked security (ILS). This market is not small. Roughly $3.6 billion of new cat bonds priced in just the first part of 2026, across about 25 deals, averaging around $144 million each (Artemis deal data, mirrored on the Apprised.news insurance desk). The investor puts up cash that sits in U.S. Treasury money-market funds, collects that yield plus a fixed risk spread, and loses principal only if a covered catastrophe hits.

Link 2: the vehicle lives offshore, and that is the point. About 95% of cat bonds and ILS are listed in Bermuda, with the Cayman Islands as the other hub. The shell company that issues the bond pays no entity-level tax. Cayman charges no corporate income, capital-gains, or withholding tax and grants exemption undertakings for 20 to 30 years. Bermuda's 15% corporate income tax, new for 2025, only touches multinational groups above 750 million euros, which these stand-alone ILS shells fall outside. So the risk premium and collateral interest compound gross and are taxed only once, at the investor's own level. Run the same income through a U.S.-based vehicle and you would stack roughly 21% federal plus about 6.5% state corporate tax on top. The U.S. Government Accountability Office put it plainly: a U.S. corporate rate "would substantially reduce the return to investors." The offshore structure exists to delete that middle layer.

Links 3 and 4: the tower, then the master policy. Your building's insurer does not face the storm alone. It buys reinsurance, and the reinsurer lays off the biggest layers to capital markets through cat bonds. That stack of coverage is the reinsurance tower. Your condo association then buys a commercial property policy on the whole building, priced on the reinsurance the carrier had to buy. When the cat-bond market demands higher spreads, the tower costs more, the carrier charges more, and the master policy renewal comes in higher, sometimes a lot higher. That is the moment the offshore math becomes a local number.

Link 5: your dues and assessments. Insurance is not deferrable. The master policy renews annually and must be paid. So the association raises monthly dues, levies a special assessment, or raises the deductible and shifts risk back onto owners, usually some mix of all three. The cost is now on your statement, permanently.

Link 6: the gap you carry alone. This is the link condo owners miss. More on it below.

You pay for the same storm twice

Most homeowners buy one policy. Condo owners buy into two. The master policy covers the structure and common areas, funded through your dues, with the offshore catastrophe load baked into its premium. Your HO-6 covers your unit interior, belongings, and personal liability, and you buy it directly. The same reinsurance pressure lifts both, so the catastrophe risk on your building is in your dues and in your personal policy at the same time.

The per-state premium levels show how heavy that load is where catastrophe risk concentrates. Florida's average homeowners premium sits near $4,231 a year, second only to Oklahoma's $4,334, with Nebraska at $4,148 and Colorado at $3,349, against a national state-average closer to $2,165 and a low-risk state like Vermont down at $1,120 (NAIC averages, viewable per state on HomeStats). Those are full-home figures, but they map the same wind, hail, and wildfire geography your building's master policy is priced against.

The loss-assessment gap, in dollars

Here is link six, the one you carry personally.

When a covered loss exceeds the master policy or falls inside its deductible, the association can assess every owner for the shortfall. Your HO-6 has a loss assessment coverage line meant to absorb your share. The problem is the default amount. Standard policies include only about $1,000 to $2,000 of it. Real assessments in 2025 and 2026 have run into the tens of thousands per unit. The math does not survive contact with a real event.

That gap is the offshore chain landing in your lap directly. The cat-bond investor was paid a spread to take the tail risk. When the tail arrives and the layers below it are exhausted, the residual flows down through the master policy deductible to an owner assessment, and your $2,000 of coverage runs out almost immediately. The rest is your problem. Raising that limit to $25,000 or more is one of the few moves a unit owner controls, and it costs very little against the exposure it closes.

The third hit: the Hurricane Tax

In the worst-exposed markets there is a third charge, and it does not even require your building to file a claim.

In Florida, ILS managers and third-party capital backed about 52% of Florida Citizens' traditional reinsurance (Artemis). Citizens is the state's insurer of last resort, and it funds itself partly through its own Bermuda cat bonds. Its Everglades Re II program is a clean example: a 2026 deal of about $600 million in cat bonds covering Florida named-storm losses, priced with all-in coupons in the rough range of 9% to 12% (a floating T-bill base near 3.75% in June 2026 plus the risk spread). That is the offshore tower behind the state backstop.

Now the part that reaches everyone. When losses blow through Citizens' funding, it can levy what it openly calls the "Hurricane Tax." A policyholder surcharge of up to 15% per account. A regular assessment of up to 2% on nearly every Florida property-casualty policyholder, auto included, not just Citizens customers. And an emergency assessment of up to 10% per year on all Florida policyholders for as many years as it takes to clear the deficit. You can do everything right, carry a well-insured building, and still get assessed because the residual market priced its risk to offshore capital and the storm beat the tower.

That is the asymmetry. The upside of the catastrophe trade is privatized and shipped to tax-neutral islands. The downside, when it overruns the layers, is socialized onto the policyholder base.

Who is actually on the other side of the trade

The big buyers are pension funds, sovereign wealth funds, and endowments, which are largely tax-exempt at the investor level too. A Canadian pension plan, the Healthcare of Ontario Pension Plan, grew its ILS allocation to about $1.44 billion by 2025. A Dutch healthcare pension system, PFZW, run by the manager PGGM, holds roughly $8.7 billion in ILS and reported a 25.2% gross return for 2024. The appeal, in one industry phrase, is "noncorrelation, pure underwriting returns." Your building's storm risk does not move with the stock market, so it is a diversifier in someone else's portfolio.

One correction, since precision is the point of this site. A common myth is that the federal Thrift Savings Plan holds cat bonds. It does not. TSP holds passive index funds and the G Fund's special-issue Treasuries, no ILS. The institutions cycling tax-advantaged underwriting returns are public and foreign pensions, sovereigns, and specialist funds, not your government retirement account.

The other escalator on the same building

Insurance is not the only fixed cost climbing on a condo, and the others compound on the same building. California's Air Resources Board has adopted a target requiring 100% zero-emission, zero-NOx sales of new space and water heaters by 2030, with the rulemaking still being finalized. For an association, that means common-area boilers and unit appliances replaced with higher-upfront equipment, and the bill moves through reserves, dues, or an assessment too. Different cause, same ledger. (One terminology note: "green corridors" is a maritime shipping term, not a home-energy policy. The home-cost driver is building electrification and low-NOx appliance mandates.)

What a condo owner can actually do

You cannot opt out of the catastrophe market or the Bermuda tax code. You can stop carrying invisible exposure.

1. Raise your loss assessment coverage. Move it from the default $1,000 to $2,000 up to $25,000 or more. This is the cheapest fix for the most direct version of the offshore chain hitting your bank account.
2. Read the master policy before you buy, not after. Ask for the renewal date, the current premium, and especially the per-unit deductible. A high master deductible is exposure that flows straight to owners.
3. Stress-test the HOA against an insurance jump. A building with a thin reserve and a hardening master policy is one renewal away from a special assessment. Run the numbers the way we do in the special assessment crisis breakdown.
4. Know what backs your carrier. If you own in Florida, Louisiana, or the wildfire West, understand that part of your coverage rides on offshore reinsurance and that residual-market assessments are a recurring line item, not a remote tail.

The renewal notice and the dues increase feel personal. The machine behind them is not. It is a legal system for moving catastrophe risk to capital that pays little or no tax on the way through, with the condo owner at the end of the chain as the backstop, twice over and sometimes three times. Knowing its shape will not lower your premium. It will change which building you buy and how much loss assessment coverage you carry into it.

This is exactly the kind of hidden, structural cost The Condo Trap was written to expose: how to read a master policy, how much loss assessment coverage you actually need, and how to use insurance health as a signal before you sign.
