MSIG Specialty Insurance America, Inc., MSIG USA’s newly established excess and surplus (E&S) insurer, has received an A+ financial strength rating and issuer credit rating with a stable outlook from S&P Global Ratings.

This rating is a significant milestone for MSIG USA and its ongoing development as a “leading data-driven specialty insurer,”, and strengthens its capacity to meet complex and changing risk requirements of its clients.

MSIG Specialty Insurance America, Inc. has been established to write non-admitted E&S business and expand the company’s capabilities in specialized commercial insurance segments.

S&P views the new entity as a core subsidiary of MS&AD Insurance Group, with its strategy being consistent with that of its parent company. Moreover, its ratings align with the broader group profile.

The A+ rating reflects MSIG USA’s strong financial foundation, disciplined underwriting approach, and global reach across 48 countries and regions.

The stable outlook mirrors that of the parent group and underscores the long-term role the new entity is expected to play in the organization’s strategy.

“This rating is an important step in the continued build-out of our specialty platform in the U.S.,” said Peter McKenna, chief executive officer of MSIG USA. “It reflects both the strength of our balance sheet and the discipline we bring to underwriting. As we expand into the non-admitted E&S market, we are focused on applying a consistent, data-driven approach to support brokers and clients navigating evolving risks.”

By incorporating MSIG Specialty Insurance America, Inc., MSIG USA can now offer a more complete strategy for specialty risk throughout its portfolio.

This addition significantly improves MSIG USA’s capacity to deliver adaptable, non-admitted solutions that complement its existing admitted products, the firm stated.
