Arch Reinsurance has promoted Ondine Bourrut Lacouture to active underwriter of Arch Syndicate 1955 at Lloyd’s.

Ms Lacouture succeeds Simon Williams, who served as the active underwriter of the syndicate since it was acquired by Arch in 2019.

Mr Williams will continue in his role as chief strategy and distribution officer of Arch Insurance International.

Jerome Halgan, president and chief underwriting officer of Arch Re, congratulated Ms Lacouture on her promotion.

“It is a tribute to her underwriting acumen and our belief in her ability to meaningfully and thoughtfully continue to grow Syndicate 1955,” he said.

Arch’s insurance and reinsurance teams have grown the stamp capacity of Syndicate 1955 more than three times since the acquisition, deploying cycle management and portfolio optimisation to enhance profitability.

Syndicate 1955 is now a highly diversified and profitable vehicle for Arch and its supporting third-party capital.

“Under Simon’s leadership, Syndicate 1955 has emerged as a strong performer at Lloyd’s and has significantly expanded its footprint,” said Hugh Sturgess, president and chief executive officer of Arch Insurance International.
