Aon Reinsurance Solutions has expanded its Thailand treaty reinsurance team with two senior hires from Lockton Wattana Insurance Brokers, as global brokers continue to invest in a market viewed as an increasingly important growth opportunity in Southeast Asia.
Chettanart Boonphayoong (pictured above) joined Aon Reinsurance Solutions Thailand in May, while Yawapa Thiamthom (pictured below) arrived in June. Both have been appointed treaty directors.

The pair previously held senior positions within Lockton Wattana's reinsurance division, where they focused on treaty placements and advisory services for insurers operating in the Thai market.
Their appointments add to Aon's existing treaty team in Thailand, which operates under the leadership of Khun Panchit and Khun Jukgrid. The hires also follow the appointment of reinsurance veteran Jukgrid Treesuttamas as senior adviser for Thailand in April.
The recruitment drive comes as international brokers and reinsurers continue to increase their focus on Thailand, one of Southeast Asia's largest insurance markets. Rising insurance penetration, economic development, infrastructure investment and growing demand for protection across both commercial and personal lines have contributed to long-term growth opportunities for insurers and reinsurers operating in the country.
Thailand has also emerged as an increasingly important market for catastrophe and climate-related risk management. The country's exposure to flooding and other natural perils has continued to drive demand for sophisticated risk modelling, capital management and reinsurance solutions, while insurers face growing pressure to manage accumulation risk and climate-related volatility.
At the same time, insurers across the region have sought to strengthen balance sheets and optimise capital following several years of inflationary pressures, catastrophe losses and changing regulatory expectations. These factors have increased the strategic importance of treaty reinsurance programmes and advisory services, creating demand for experienced reinsurance professionals with strong local market knowledge.
"Thailand is a key growth market for us in APAC, and we are committed to bringing the best talent and capabilities to our clients and partners here," said Musa Adlan, managing director of Aon Reinsurance Solutions Asia.
"Chettanart and Yawapa are highly experienced and well respected in the Thailand reinsurance market. Their market knowledge, client relationships, and treaty expertise speak for themselves."
Competition for experienced reinsurance talent has intensified across several Asian markets as brokers seek to expand advisory capabilities and deepen relationships with local insurers. Thailand has been a particular focus for investment, supported by continued economic growth and increasing demand for specialist risk and capital solutions.
The appointments also come against a backdrop of relatively favourable reinsurance market conditions. According to Aon, global demand for reinsurance increased by around 10% during the April 1 renewal season, while some Asia-Pacific markets benefited from rate reductions and ample capacity, providing insurers with greater flexibility when structuring reinsurance programmes.
Strengthening local expertise is increasingly seen as a key differentiator as clients seek support navigating a more complex risk landscape while taking advantage of evolving market conditions.
