Bamboo Insurance Launches MS Transverse Partnership to Expand Admitted Capacity and Improve Homeowners Affordability in California

New partnership adds $150M in capacity, introduces lower-premium options, and expands flexibility in high-demand markets

LOS ANGELES, July 17, 2026 /PRNewswire/ -- Bamboo Insurance today announced the launch of a new partnership with MS Transverse Insurance Company, expanding its admitted homeowners and dwelling fire capacity in California. The partnership adds approximately $150 million in new admitted capacity and introduces additional options within Bamboo's existing portfolio, increasing affordability and flexibility in high-demand, catastrophe-exposed regions.

The expansion strengthens Bamboo's ability to serve homeowners, landlords, and agents across constrained markets, including Los Angeles, San Diego, and San Francisco, where limited carrier appetite has restricted access to admitted coverage.

"Our partnership with MS Transverse represents a meaningful step forward in how we approach both affordability and capacity in challenging markets," said John Chu, CEO of Bamboo Insurance. "By expanding our carrier relationships and introducing more precise underwriting tools, we're able to deliver more competitive pricing while maintaining the discipline needed for long-term sustainability."

The partnership expands Bamboo's existing admitted program offerings by introducing options with flexible coverage structures, providing more accessible entry points into admitted homeowners' coverage.

These options are enabled by enhanced underwriting segmentation and structured coverage options that allow for more tailored risk selection. Key features include higher deductible options up to $10,000, allowing policyholders to tailor coverage to their needs, and mandatory water damage sublimits with flexible tiers, giving policyholders additional structural options.

The partnership also introduces a new claim-free discount structure that rewards policyholders for sustained claim-free tenure, with discount levels increasing incrementally over time.

Together, these enhancements strengthen Bamboo's competitiveness in the DIC and admitted homeowners' markets, enabling greater flexibility for higher-value homes and improving the ability for agents to place business within admitted markets rather than surplus lines.

The added capacity and refined underwriting approach come as California's homeowners market continues to face pressure from rising reconstruction costs, catastrophe exposure, and reduced insurer participation.

"MS Transverse enhances our ability to continue writing in challenging markets while offering more competitive and configurable pricing options for agents and their clients," Chu added.

The expanded capacity is available statewide for new business and renewals with effective dates beginning July 17, 2026. Policies are distributed through Bamboo Insurance's established agent and partner network and remain subject to underwriting guidelines, eligibility requirements, and regulatory approvals.
