In 2025, there were 179 bank deals, indicating a strong M&A trend that analysts believe continues to gain momentum, largely due to accelerated regulatory approvals. Current regulatory conditions allow for quicker deal evaluations, a significant change from the past. During the Biden administration, approval could take up to 17 months, while the duration has now shortened to three to four months, as noted by Margaret Tahyar of the law firm Davis Polk.
Rahul Chandarana from EY-Parthenon highlights increased capital among banks and previous merger activity as signs of forthcoming M&A activity. David Danielson from Wolf & Company explains that smaller banks often pursue acquisitions due to aging leadership and rising costs, while larger institutions leverage mergers to optimize technology and compliance expenses, expand into new markets, and enhance their competitive positioning. However, analysts caution that this merger trend could be affected by ongoing geopolitical tensions, such as the war in Iran.
