US Regional Bank M&A Poised to Accelerate

US regional banks struggle to compete with giants such as JPMorgan Chase because of constraints tied to their asset size and the cost of technology investment. The second Trump administration’s looser merger reviews have made consolidation an option for expanding market reach and spreading systems costs. Fifth Third Bancorp’s October 6, 2025, announcement of an all-stock, $10.9 billion acquisition of Comerica underscored the industry’s pressure to gain scale.

American Banker reported on July 7, 2026, that dealmaking came to an abrupt halt in the spring of 2026 as US and Israeli attacks on Iran triggered market turmoil, after activity had picked up in the second half of 2025. With the United States and Iran entering peace talks, Davis Polk partner Margaret Tahyar expects major transactions to resume. However, the favorable regulatory window could narrow in 2029, and the precise timing remains unclear.
