Arch Insurance International has appointed Roger Moniz (pictured) as global head of transactional risk, giving brokers placing multi-jurisdictional M&A-linked insurance a single underwriting contact across nearly every major deal market simultaneously.
Moniz, promoted from executive assurance underwriting manager, will lead Arch's transactional risk portfolio from Bermuda - covering representations and warranties, warranty and indemnity, and tax insurance across North America, Europe, the Middle East and Africa, Asia-Pacific and Australia. He reports to Matt Smith, managing director of Arch Insurance Bermuda, and works alongside Maggie Munns, head of executive assurance at Arch Insurance International. Moniz joined Arch in Bermuda in 2021, having previously held roles at Aon and RenaissanceRe.
Smith said Moniz is well placed to lead the expansion of the transactional risk portfolio.
Global M&A deal values reached nearly $5 trillion in 2025, and the insurance market that travels alongside them has grown proportionally. Marsh placed a record $91.6 billion in transactional risk limits that year, up 34% year on year. The UK alone recorded historic notification and payout levels. Average W&I and R&W quoted rates rose from 2.5% in Q4 2024 to 3.23% in Q4 2025 as claims volumes increased alongside rising deal activity.
That combination - higher volumes, rising rates, more complex claims - is pushing both insurers and brokers toward more structured global platforms for the class.
Arch is not the first to move in this direction. In July, DUAL built a unified transactional risk practice spanning more than 80 underwriters across 11 jurisdictions, explicitly in response to rising multi-jurisdictional demand. The Arch appointment follows the same logic from the underwriting side.
For brokers running multi-jurisdictional M&A processes - deals spanning a US acquisition, a European target, and an APAC subsidiary, for example - the practical challenge has been coordinating coverage across multiple underwriting contacts at the same carrier, each handling their own geographic jurisdiction. A single global head with portfolio-level authority across all those markets consolidates that conversation.
Moniz's remit covers underwriting authority across Arch's transactional risk book globally, not simply a relationship management role. For brokers assessing whether to bring a complex cross-border deal to Arch rather than a competitor, the relevant question is whether a carrier whose transactional risk strategy is now coordinated under one leader can price and bind a multi-part programme more efficiently than one whose jurisdictions are still managed independently. The appointment signals Arch believes it can.
Capacity in some transactional risk lines has been tightening even as submission volumes rise - a combination that makes early engagement with a carrier's senior leadership more valuable than it was two or three years ago, when capacity was ample and any submission would find a market. Brokers with active deal pipelines should be establishing relationships with Arch's transactional risk team now rather than approaching the market at the point a specific transaction needs binding.
