Hamilton prices its cat bond at 1.6 times expected loss

Bermuda-based Hamilton closed its Easton Re 2027-1 catastrophe bond on 3 November at 300 million dollars, upsized from a 250 million dollar target. The spread tightened from initial guidance of 4.75–5.25% to 4.25%, against an expected loss of 2.66%. By our calculation the multiple is roughly 1.6.

Location: BERMUDA

According to Artemis, the bond covers named storms in the US, Puerto Rico and the Virgin Islands, as well as earthquakes in the US and Canada. Pricing was first revised to a 4–4.75% range, and the final spread settled at 4.25% rather than at the bottom of that range. The multiple is the ratio of the spread to expected loss; at 1.6 it sits well below the 2.4 market average Artemis reported for the first nine months. That the bond grew by 50 million dollars while getting cheaper shows capital is willing to carry modellable US catastrophe risk for a lower return.

The same trend shows up on the balance sheets of the big Bermuda reinsurers. Arch's gross reinsurance premiums fell 8% in the third quarter to 2.31 billion dollars. Chief executive Nicolas Papadopoulo said property pricing would stay under pressure after a light catastrophe year, and that Arch was cutting its share of business whose returns fell below target. According to Business Insurance, he sees demand for marine and terrestrial war cover as an opportunity; Arch's quarterly catastrophe losses rose to 234 million dollars, and the share linked to the Iran conflict was not disclosed.

Talay assessment

Bottom line

A 1.6 multiple shows capital competing on volume rather than price in US catastrophe risk. Traditional reinsurer Arch is trimming its share while bond investors accept thinner spreads, so property catastrophe protection will get cheaper again in January. The same capital is not flowing into war cover, which Arch reads as a pricing opportunity.

Likely effects

US property catastrophe coverPositiveWeeks
A spread down at 4.25% puts downward pressure on reinsurance costs for US insurers at the 1 January and June renewals.
Cat bond investorsNegative1–6 months
A multiple below the 2.4 average means the excess return over expected loss is thinning, and a major catastrophe would not be covered by the spread.
War coverNegative1–6 months
Arch treating war demand as an opportunity supports the view that pricing in this line will decouple from the broader decline.
