MSIG USA has appointed Oscar Aguilar as head of excess and surplus property.

Aguilar brings more than two decades of property insurance experience, particularly in E&S, shared and layered property, and complex commercial risks.
The executive joins MSIG USA from Liberty Mutual Insurance, where he most recently served as senior vice president and national manager of major accounts property, shared and layered.
He previously led US retail property for Liberty Mutual and spent six years at Ironshore Insurance, where he managed wholesale property across the Western and South Central regions.
Earlier in his career, Aguilar served as senior vice president at Brit Insurance, and also held underwriting and leadership roles at Maiden Reinsurance North America, GMAC RE, SRO Napa, St. Paul Companies and Sherwood Insurance.
“Oscar brings the depth of underwriting expertise and market perspective that are essential to building a differentiated E&S property business,” said Peter McKenna, CEO of MSIG USA.
