Bank mergers and acquisitions (M&A) stalled significantly in the first half of 2026, dropping to just $17.4 billion in deal value. This represents a substantial decrease from the 117 deals announced in the latter half of 2025 and the $50.5 billion in deal value for the entire year 2025. The period from March through June 2026 saw an even sharper decline, with only $2.3 billion in deal value. This downturn is largely attributed to the U.S.-Israeli attacks on Iran in late February, which introduced geopolitical and economic uncertainties, causing potential buyers and sellers to defer transactions.
Eighty-three transactions were announced between January 1 and June 30, 2026. A striking 87% of the total deal value for this period originated from deals announced before February 28, indicating the immediate impact of the conflict. Analysts like Laurie Havener Hunsicker of Seaport Research Partners noted that an environment of volatility and uncertainty leads buyers to pull back. This contrasts sharply with analyst predictions at the start of the year, which anticipated continued M&A momentum from 2025, driven by lower interest rates and a more favorable regulatory environment under the Trump administration.
Despite the overall slowdown in bank M&A, the wealth and asset management sector in North America experienced an increase in dealmaking during the first half of 2026, completing 213 transactions. However, this growth did not include major "mega-deals." Looking ahead, there is pent-up demand for deals, and a faster regulatory approval process is in place. Hunsicker is optimistic that M&A activity will "substantially accelerate" in the second half of 2026 and throughout 2027, provided geopolitical tensions ease and the Strait of Hormuz reopens for stable trade. The current M&A-friendly regulatory landscape, particularly regarding antitrust enforcement, is also seen as a crucial factor, with some experts suggesting that banks may feel pressure to complete deals before the 2028 presidential election, which could bring a less favorable regulatory environment.
