Marsh Elevates Marcus Baker to Marine Chairman as Michael Walls Takes Global Reins

Marsh's Marine Leadership Handover: Baker to Chairman, Walls to Global Head

Marsh has announced a leadership transition in its marine, cargo and logistics practice, appointing Marcus Baker to the newly created role of chairman and promoting Michael Walls to global head of the business. Both appointments take effect on 1 January 2027, and both executives will report to Andrew George, president of specialty and industry at Marsh Risk.

Baker brings 45 years of industry experience, 32 of them at Marsh, where he has been instrumental in building the marine practice. As chairman, he will maintain key relationships with global markets and lead strategic initiatives tied to world trade. Walls, who joined Marsh in 2005 and currently leads marine for Marsh Asia, will take over the global strategy.

The succession arrives at a challenging time for marine brokers. Shipping through the Strait of Hormuz remains severely disrupted, with at least 15 container ships attacked in a ten-day period in mid-October, according to Willis Re. This has caused sharp shifts in war risk cover and exposed gaps between policy wordings that brokers must navigate. Competition for specialist marine talent is also intense, with recent hires by Gallagher and law firm DAC Beachcroft underscoring demand.

Marsh's decision to keep Baker in a chairman role suggests a focus on continuity in client relationships, while Walls's elevation from Asia signals where the firm expects marine risks to grow—particularly as Chinese exports shift toward emerging markets and Asian trade routes become more central to global supply chains.

Why Marsh Is Betting on Asia Expertise and Continuity in Marine Brokerage

Why Marsh Is Keeping Baker Close

Marcus Baker's move to chairman is not a retirement but a deliberate retention of market relationships. With 32 years at Marsh and deep connections across global marine markets, Baker's continued presence is designed to reassure clients placing business through Marsh that their key contacts remain intact. In a sector where war risk and cargo cover are under strain, stability in relationships can be a competitive advantage.

The Asia Signal in Walls's Promotion

Michael Walls's elevation from head of Marsh Asia to global head is a clear indication of where the firm sees future growth. As Chinese exports shift toward emerging markets and Asian trade routes become more central to global supply chains, having a leader with direct experience in those corridors matters. For brokers with clients exposed to Asian trade, Walls's background should translate into better understanding of local risks and solutions.

Competitive Pressure in Marine Talent

The marine brokerage market is not standing still. Gallagher recently hired a veteran hull and war broker, and DAC Beachcroft added two marine and energy coverage partners. This competition for specialist expertise means Marsh's succession plan must not only retain Baker's relationships but also ensure Walls can hit the ground running. The firm's ability to attract and retain talent will be tested as demand for war risk and supply chain expertise grows.

What This Means for Clients and Competitors

For clients, the transition should mean continuity in service, particularly for those with complex war risk or cargo exposures. For competitors, Marsh's move signals a focus on Asia and a commitment to maintaining senior-level market connections. The real test will come after January 2027, when Walls assumes global leadership and Baker's chairman role evolves. If the transition goes smoothly, Marsh could strengthen its position in a market where expertise is at a premium.

What Marsh's Marine Succession Means for Brokers, Clients and Competitors

For marine insurance clients, the key takeaway is that Marsh is prioritising continuity and Asian expertise as war risk and supply chain disruptions intensify.

• 0–6 months: Clients with exposure to Strait of Hormuz routes should review war risk cover and policy wordings for gaps, as attacks continue and cover terms shift. Engage your Marsh broker to confirm coverage details before the January 2027 leadership change.
• 6–24 months: Expect Marsh to deepen its focus on Asian trade corridors under Walls. Clients with supply chains linked to China and emerging markets should assess whether their broker's expertise aligns with these shifting routes.
• 2–5 years: The marine brokerage market will likely see continued talent competition and consolidation of specialist expertise. Clients should monitor whether Marsh's new leadership maintains the relationships and market access that Baker built.
