AM Best released a special report detailing significant growth and emerging risks in the U.S. property casualty fronting insurance market. The study found that unrated or unauthorized reinsurers are increasingly introducing credit risk into these complex transactions.
Why it matters
Fronting arrangements allow managing general agents to launch programs with greater speed and autonomy. However, reinsurers are now demanding that fronting companies retain more risk to ensure discipline in underwriting and decision-making.
Fronting specialists grew their premium base from $1.8 billion in 2015 to nearly $20 billion in 2025. The broader industry, including roughly 30 fronting organizations, now generates over $30 billion in annual premiums.

Market Dynamics
The fronting market reflects a structural shift toward outsourcing risk within the broader property and casualty sector. This trend mirrors cycles of rapid expansion in alternative risk transfer, where non-traditional players play an increasingly large role in underwriting.
Increased credit risk in fronting arrangements could lead to tightened underwriting standards and higher costs for managing general agents. Investors in insurance-linked portfolios should monitor whether retained risk requirements affect the profitability of these underwriting programs.
The takeaway
The rise of fronting arrangements has provided significant operational flexibility for insurance programs nationwide. However, the reliance on unrated reinsurers serves as a reminder for stakeholders to verify the financial security behind their insurance products.
