Wednesday's edition was about the price of money: a mortgage rate set by a Treasury market reacting to an oil shock. This one is about the price of risk, and it shows the same war moving through a different market.

In 2026, three kinds of insurance are sending three different price signals. War-risk cover for ships got far more expensive. Catastrophe reinsurance, the insurance insurers buy, got cheaper. And the homeowners policy on your house is still rising nationally, though more slowly. The gap between those three is where the story is, and the Florida exception explains why.

Before the Iran war, insuring a tanker for a Hormuz transit cost a sliver of the ship's value. Sources disagree on the exact baseline: Insurance Business puts it at about 0.10% to 0.125% of vessel value, while The National cites 0.25%. Either way, by March it was around 2% to 3%. At 3%, insuring a $100 million tanker costs about $3 million per voyage.

Then it moved with the news. After the June 17 US-Iran ceasefire, Insurance Business reported on June 25 that premiums fell from about 5% to 2% of vessel value within six days, still roughly 20 times the pre-war level. By July 17, with tensions escalating again, The National put the range at 3% to 10%. Marsh's global head of marine, Marcus Baker, told it: "War rates have been on a roller coaster mirroring the development of the price of oil."

Here is the part that surprised us. Washington built a $40 billion backstop. Per Insurance Business on May 18, the US Development Finance Corporation's facility, backed by insurers including Chubb, AIG and Berkshire Hathaway, had written zero business: "not a single ship has used it" and "not one dollar of coverage has been placed." One underwriter explained why: "The reduced traffic going through the Strait has nothing to do with what insurance is available or not available. It's purely just a captain or a shipowner not wanting to put their crew at risk." The market never closed. It just got expensive.

Reinsurance is the insurance that insurers buy. Per AM Best, September 29: "Property catastrophe reinsurance renewal pricing reached its peak in 2023, and began softening in 2024, a downward trend that persisted through the 2026 reinsurance renewals."

Fitch, via Insurance Journal on September 8, says 2026 renewals "demonstrated a strong shift to a buyers' market, particularly for property risk, where rates declined by double digits," and expects "further market softening in 2027." It puts alternative capital at "a record high of over $144 billion."

So one industry, in one year, raised one price by multiples within days and cut another by double digits over twelve months.

AM Best reports the homeowners line swung from "a more than $1.3 billion net underwriting loss in 2024 to a $16.5 billion net underwriting gain" in 2025. The first-half 2026 loss ratio was 48.4%, "its lowest midyear mark in five years."

Yet rates are still going up. "The average approved homeowners rate increase nationwide dropped to 4.3% through the first half of 2026, down from 7.6% in 2025 and 13.5% in 2024." AM Best does not say whether insurers are passing savings through or keeping them, and we are not claiming either. The fact is narrower: the price is still rising, more slowly, in an industry that just posted a record underwriting gain.

Florida is the opposite case. Per Fox 13, the state's 30-day average requested homeowners rate is -4.8%, versus -1.1% a year earlier and +5.2% five years ago. Since January 2024, 48 carriers have filed for decreases. Regulators approved cuts at four private insurers covering more than 62,000 policies, from 3.2% to 10.4%, and Kin announced decreases averaging more than 20% for coverage in Broward, Miami-Dade and Palm Beach counties. Fox 13, citing S&P Global, says Florida had the lowest rate change nationally in 2025, 0.92% against a 5.5% national average.

What changed? Per Beinsure on September 25, Florida's share of US homeowners lawsuits fell from 79% in 2020 to 41% by 2025, which lawmakers credit to the 2022 reforms, and "Global reinsurers are very confident in supporting Florida regional insurers."

Louisiana shows the mechanism more plainly. Per Reinsurance News, SURE, a reciprocal exchange, said its 7.5% decrease was "primarily driven by a reduction in reinsurance costs." Commissioner Tim Temple said reinsurers had asked the state to address its three-year rule and clarify catastrophe claims processes.

That is the transmission mechanism, as far as the sources show it. Reinsurers are global capital. They price a state's legal system as well as its storms. Cheaper reinsurance reaches a homeowner where the state gave reinsurers a reason to trust its courts. Where it didn't, the savings stay upstream.

The government is not simply absorbing more risk everywhere. It depends on whether private pricing can clear.

In shipping, the government facility sits unused because the market priced the risk. In Florida, the state insurer is shrinking: Citizens Property Insurance went from roughly 1.4 million policies in September 2023 to about 270,000, per Insurance Business on September 4, including 45,000 non-renewal notices. A Citizens spokesperson acknowledged that "private market premiums are often higher than Citizens' rates." In California the opposite is happening: as we reported in our July 23 edition, the FAIR Plan had about 668,000 policies and $724 billion in exposure by January 2026.

If you own a home in Florida: your renewal is the moment to shop, since filed rates are falling. If Citizens non-renews you, you have about a year to find private coverage, and per Citizens the private price is often higher. Compare before assuming the cut applies to you.

If you own a home in a state that hasn't changed its legal environment: the national 4.3% average increase is the more relevant number. A reinsurance price cut does not reach you automatically.

If you underwrite property deals: model insurance by state, not by national average. The national and Florida figures above point in different directions.

If you import goods through the Gulf: war risk is a freight cost, and the premium moves with the headlines, as Baker's comment about oil suggests.

War risk reprices in days, because underwriters reassess in real time. Catastrophe reinsurance reprices at annual renewals. Retail homeowners reprices when a regulator approves a filing. Same industry, same war, three clocks.

In the gap between the fastest clock and the slowest, whoever sits in the middle keeps the difference. We don't know how much of the 2025 underwriting gain is that spread, and the sources don't say. But the structure is visible: price signals travel faster than they are passed along, and legal systems decide where they land.

First, the Florida decline has several named causes, including litigation reform, reinsurance costs and insurer competition. The sources do not separate them, so we cannot say how much is reinsurance.

Second, the -4.8% is an average of requested rates, not approved or paid ones.

Third, AM Best gives no statement on pass-through, so "savings are staying upstream" is our inference, not a finding.

Fourth, war-risk sources conflict on the pre-war baseline (0.10% to 0.125% versus 0.25%), and the DFC facility figure is as of May 18 and may have changed.

Claim: US property-catastrophe reinsurance pricing at the January 1, 2027 renewals will be lower than a year earlier, with broad-based rate declines across the market rather than isolated concessions.
