2025 Global Transactional Risk Insurance Market: Premium Growth Returns

Walking through Midtown Manhattan or grabbing a coffee near the New York Stock Exchange, you can usually feel the temperature of the deal-making world before the reports even hit the wire. Right now, that temperature is rising. For years, the corporate world enjoyed a “buyer’s market” for transaction risk insurance, where premiums for Warranties and Indemnities (W&I) policies drifted downward. But as we move through 2026, the tide has officially turned. The global market has hit a pivot point, and for the high-stakes M&A environment in New York City, this shift is more than just a statistical quirk—We see a fundamental change in how deals are structured, and priced.

The Complete of the Premium Slump: A North American Rebound

According to the Global Transactional Risk Insurance Report 2025 from Marsh, the industry has seen a dramatic inversion of a three-year trend. After a prolonged cycle of falling costs, premiums for primary W&I policies are climbing again across most geographic regions. This isn’t a subtle nudge; in North America, primary W&I premiums surged by 16% year-over-year. To put that in perspective, this follows a 14% decline in 2024, representing a sharp V-shaped recovery in pricing that catches many corporate treasurers and legal teams off guard.

This pricing volatility is happening against a backdrop of explosive activity. The global value of M&A operations reached nearly $5 trillion in 2025, a staggering 37% increase over the previous year. When you glance at the sheer scale of these transactions, the pressure on the insurance market becomes clear. The number of deals rose by 12% compared to 2024, but the real story lies in the “mega-deals.” There were 70 operations valued at over $10 billion—an 81% increase year-over-year—and 617 operations exceeding the $1 billion mark. For firms operating out of the financial hubs of New York, these numbers signal a return to aggressive expansion and high-value acquisitions that require robust M&A strategy and insurance coverage.

Claims, Payouts, and the North American Paradox

While the volume of deals is climbing, the cost of risk is also intensifying. The insurance market is reacting to a rise in both the frequency and severity of claims. The global landscape shows a worrying trend: Europe has seen claims double, and the United Kingdom has hit record levels of notifications and payments. Asia has also seen strong increases in claims activity.

North America presents a fascinating paradox. In this region, the number of claim notifications actually decreased slightly. However, the actual payments made on those claims reached a new historical maximum. This suggests that while fewer things are going wrong, the things that do go wrong are significantly more expensive to fix. This “severity spike” is a primary driver behind why insurers are hiking premiums. When a single breach of warranty results in a record-breaking payout, the entire risk pool feels the impact, leading to the 16% premium hike we are seeing across the board.

The Surge in Specialized Tax Insurance

Beyond standard W&I policies, there is a burgeoning appetite for specialized protection. Tax insurance in North America has seen an unprecedented boom, with the number of policies jumping by 82%. This trend mirrors a similar move in Europe, where policy counts grew by over 50% and the total limits insured more than doubled. As regulatory scrutiny increases and tax laws evolve, the desire to ring-fence tax liabilities during a merger has become a priority for C-suite executives.

The scale of this activity is reflected in the data from Marsh Risk, which placed $91.6 billion in transactional risk limits in 2025. Here’s a 34% increase over 2024, achieved through more than 3,800 policies across nearly 1,800 distinct operations. For a city like New York, where the density of Fortune 500 companies and private equity giants is unmatched, these trends dictate the feasibility of upcoming deal pipelines and the necessity of updated risk management frameworks.

Navigating the New Risk Landscape in New York City

Given my background as an Executive Geo-Journalist focusing on the intersection of finance and local infrastructure, the “cheap insurance” era of the early 2020s is over. If you are navigating a merger or acquisition in the New York metropolitan area, the increased cost of W&I and tax insurance means you can no longer treat these as secondary line items. They are now primary levers in deal negotiations.

To manage these rising costs and the increased severity of claims, you need a specialized local team. Here are the three types of professionals you should be engaging right now:

Specialized M&A Legal Counsel

Look for attorneys who specialize specifically in transactional risk and W&I policy negotiation. You need a professional who can scrutinize the “exclusions” section of a policy to ensure that the 16% premium increase is actually buying you comprehensive coverage, rather than a stripped-down version of a previous policy.

Corporate Risk Brokers with Global Reach

Because the trend is global but the impact is local, your broker must have a direct line to the global underwriters who are setting these rates. Seek out brokers who can provide comparative data across North America and Europe to leverage better terms based on the current global volume of $5 trillion in M&A activity.

Transactional Tax Strategists

With the 82% spike in tax insurance policies, the demand for these experts is at an all-time high. Look for strategists who can perform a “pre-insurance” audit to clean up potential liabilities, which may help in securing more favorable limits and lower premiums from insurers.
