Key Points

  • According to Marsh research, transaction risk insurance pricing is beginning to firm after several years of declines, amid a pickup in M&A activity with larger and more complex deals.
  • The 2025 Global Transaction Risk Insurance Report shows that pricing rose across all regions in 2025, reversing the post-pandemic downward trend. Average premiums for representations and warranties insurance, which protects buyers and sellers against deal-related losses, rose 16% in North America, 8% in Asia, and 5% in Europe. The UK and Pacific regions were broadly flat after years of declines.
  • "The pricing increase is primarily driven by claims activity," said Craig Schioppo, Marsh's global head of transaction risk, in an email. He cautiously characterized the shift as the start of a market tightening cycle, suggesting it more likely reflects pricing returning to levels seen several years ago.

Deeper Dive

The price increases come as global M&A deal value climbed to nearly $5 trillion in 2025, driven largely by a surge in "megadeals," including 70 deals exceeding $10 billion (up 81% year-over-year) and 617 deals above $1 billion, Marsh said.

The insurance brokerage said it arranged a record $91.6 billion in transaction risk insurance limits globally in 2025, up 34% year-over-year, reflecting increased demand for deal protection as transactions grow in size and complexity, with parties increasingly turning to insurance to manage risk.

Meanwhile, M&A-related disputes are also on the rise as deal activity regains momentum and macroeconomic pressures such as interest rate and currency fluctuations increasingly seep into post-closing disputes, according to a recent report from Berkeley Research Group (BRG), a consulting firm based in Emeryville, California.

The firm surveyed more than 200 lawyers, private equity professionals, and corporate financial advisors globally, with approximately 34% of respondents saying indemnification provisions and representations and warranties insurance were involved in disputes last year.

"In the U.S., if you have R&W insurance and there's a post-closing issue, it's almost customary to file a claim and then work it out later," said Frank Dery, a managing director at BRG in Chicago, in the report. "Few ultimately get paid, but the existence of insurance encourages parties to take the first step and file a claim to investigate the issue, which is more likely than when there's no insurance."
