Total catastrophe bond and insurance-linked security listings on the Bermuda Stock Exchange exceeded $68.5 billion in the first-quarter of year, as the BSX further grew an already dominant market share to some 95 per cent, Artemis is reporting.

By the end of 2025, BSX listings had already grown to $65.2 billion, more than 93 per cent of the cat bond market, the news site reported.

Artemis is the news, analysis and data media service devoted to the catastrophe bond, ILS, non-traditional reinsurance capital, insurance linked investments and associated alternative risk transfer markets.

A recent quarterly market report detailed how sponsors and arrangers continue to select the BSX as the stock exchange of choice for the asset class.

During the first-quarter of 2026, the BSX welcomed 70 new cat bond and ILS related listings, recording volumes of over $6.63 billion of newly listed notes and structures.

Almost $6.3 billion of that was newly listed cat bond notes and programmes, a very significant proportion of total market issuance, Artemis said.

The total number of ILS related listings on the BSX reached 777 by the end of the first quarter of 2026, with catastrophe bond linked ILS listings contributing 557 of the total.

BSX listed ILS securities and programmes providing catastrophe insurance or reinsurance protection had a total value of $60.2 billion by the end of the first quarter of 2026, up from $57.2 billion at the end of 2025.

Total cat bond related listings, including non-cat risk exposed issuances and counting preference shares as well, reached almost $60.9 billion by March 31, 2026.

In addition, the BSX was also the listings home to a further almost $7.7 billion of mortgage insurance-linked securities, as of the end of the first quarter this year.
