Global insurance and reinsurance broking group Aon has appointed Karl Hamann to Chief Executive Officer (CEO) of the Philippines, effective April 1st, 2026, subject to regulatory requirements.
Since 2022, he has served as the CEO of Indonesia, where he has implemented modernisation initiatives, strengthened commercial execution, and enhanced market connectivity.
Hamann will relocate to Manila in the coming months and continue to report to Andrew Minnitt, Head of Southeast Asia.
He succeeds Darren Oliver, who will transition to his newly appointed regional role as Head of Market Development, APAC Health Solutions, based in Singapore.
In his new role, Hamann will focus on advancing Aon’s integrated solutions strategy and helping clients navigate interconnected risks. Additionally, he will work closely with regional solution line leaders to align priorities, deepen client engagement, and support sustained growth.
Hamann has over three decades of experience across Asia Pacific and global markets, with deep expertise in insurance, risk advisory, and operational leadership. He has held CEO roles across the Philippines, Papua New Guinea, Malaysia, Singapore, and South Asia.
Minnitt commented on the appointment, “Karl brings a rare combination of on-the-ground experience, commercial discipline and an ability to lead with clarity through change. His familiarity with the Philippines market and his track record across the region make him exceptionally well-placed to guide the business forward. I’m confident he will build on the strong momentum that Darren established in recent years, supporting both our clients and colleagues as the market continues to evolve.”
He continued, “These leadership appointments reflect Aon’s continued investment in developing talent and strengthening alignment across Southeast Asia — creating greater opportunities for our colleagues while ensuring we remain well positioned to support clients’ evolving needs in a rapidly changing environment.”
Hamann said, “The Philippines has been an important part of my professional journey, and I’m excited to re- engage with the market in this new capacity. Darren has laid down a solid platform for the business, and I’m eager to work with the team to continue strengthening our support for clients and driving the next phase of growth.”
Earlier this month, Aon appointed Alexander Krasavin as Regional Managing Director covering Asia Pacific.
