Arch shrinks reinsurance premiums and leans on third-party capital
Arch's gross reinsurance premiums fell 8% in the third quarter to $2.31 billion. In remarks reported by Artemis on 2 November, the CEO described third-party capital as capacity with a lower cost of capital. The company is cutting its share of business where returns fall below its threshold.
War and catastrophes eroded earnings. According to Business Insurance, Arch's third-quarter net income fell 23.5% to $1.03 billion. The combined ratio rose from 79.8% to 82.5%, and catastrophe losses climbed from $72 million to $234 million. The company did not separately disclose losses arising from the Iran war. CEO Nicolas Papadopoulo said he sees demand for marine war and land war cover as an opportunity.
As prices fall, the capital structure is shifting. Papadopoulo expects pressure on pricing in short-tail property catastrophe and excess of loss business to continue. Excess of loss is reinsurance that covers losses above a set threshold. The company uses third-party capital through sidecars, catastrophe bond sponsorship and funds, but does not disclose the income from them. The finance chief said profit commissions from these vehicles could fall in a normal catastrophe year.
Talay assessment
Bottom line
Arch's results capture how a large Bermuda reinsurer behaves in a softening market: it shrinks premiums on its own balance sheet, passes risk to cheaper third-party capital and looks for growth in war cover. Property catastrophe capacity will therefore stay plentiful, and price declines will continue into January. Demand on the war line, by contrast, points to prices staying firm there.
Likely effects
- Property catastrophe pricingPositiveWeeks
Growth in capacity with a lower cost of capital keeps pushing catastrophe prices down at the January renewal.
- War coverNegative1–6 months
Arch's view of marine and land war demand as an opportunity supports the case that pricing on this line will diverge from the general softening.
- Reinsurer profitabilityNegative1–6 months
With premiums down and catastrophe losses up, profit commissions are carrying profitability; that support could fade in a normal catastrophe year.
