Bermudian William Soares has been promoted to the role of chief executive officer of Arch Reinsurance Ltd in Bermuda.

At the same time, Arch announced the promotion of Jon Schriber to CEO of Arch Reinsurance Company in the US.

Both appointments are effective immediately and both executives will report to Jerome Halgan, the recently promoted CEO of Arch’s Global Reinsurance Group.

“William and Jon are outstanding leaders who have played significant roles in the success and growth of our reinsurance business; Jon having meaningfully strengthened our presence and expanded our portfolio in the US, and William having played a central role in building our industry-leading casualty and specialty business here in Bermuda,” Mr Halgan said.

“Their deep expertise, strong relationships and commitment to underwriting excellence position them well to further establish Arch Re as the leading, global reinsurer of choice. I am delighted to recognise their accomplishments with these well-deserved promotions.”

Mr Soares joined Arch in 2006 and has held various roles of increasing responsibility within Arch Re in Bermuda. He has served as president of Arch Reinsurance Ltd since 2025.

Mr Schriber joined Arch as president of Arch Reinsurance Company in 2023.

“I am honoured for the opportunity to lead and work alongside such an exceptional team,” Mr Soares said. “Together, we will continue to focus on delivering the insight, responsiveness and underwriting discipline our clients value while pursuing opportunities for sustainable growth.”

Mr Schriber said: “I am excited to take on this expanded role, and I’m grateful for the trust Jerome has placed in me.

“Our success is built on the strength of our teams, our underwriting acumen and the relationships we have cultivated over time. I look forward to continuing to build on that strong foundation.”
