Unlocking the Potential for Regional Bank Mergers

In a significant shift, regulatory barriers have been lifted, paving the way for large banks to pursue acquisitions. According to recent data, North America bank merger value has fallen by more than half in the first six months of 2026, with a total value of $30.1 billion, compared to the year-earlier period.

Among the top contenders, Wells Fargo and Citigroup stand out as the only U.S. megabanks with room under the 10% national deposit cap to buy a large regional bank. Both institutions have cleared key regulatory hurdles and are now in growth mode.

Wells Fargo CEO Charlie Scharf has signaled openness to a ‘transformative deal’, while Citigroup CEO Jane Fraser has emphasized the bank’s focus on organic growth, not mergers and acquisitions. However, there are reports that Citigroup executives have discussed the idea of buying a major regional lender to bolster its deposit base.

A viable target for either bank needs to be large enough to move the needle, but small enough to keep the acquirer comfortably beneath the 10% national deposit cap. On top of that, a complementary branch network, good cultural fit, and quality deposits are must-haves, making most deals hard to justify.

After running screens on those criteria, five regional banks emerge as strong contenders for either bank. These include Fifth Third, Huntington, Citizens, KeyCorp, and Regions. Each of these banks has a unique profile that could complement the acquirer’s existing business.

Beyond these five, a bank that would work specifically for Wells Fargo is Zions, which provides relationships across high-growth Western states, fitting well with its footprint. For Citigroup, a possible target that makes sense is First Horizon, with its presence across the fast-growing U.S. Sunbelt.

The moment is still favorable for mergers, according to Frank Sorrentino, a mergers banker at Stephens. However, few banks are eager to sell when profits and share prices are rising.

Activist investors have pushed banks to improve shareholder returns, creating more discipline around deals. The number of regional banks will shrink from 49 to as few as 30 by 2030, according to Bain’s predictive model. This consolidation will create one to three new megabanks with at least $1 trillion in assets by 2030.

While Wells Fargo and Citigroup are in the driver’s seat, they have yet to make a move. The question remains: will they take a swing, or will the regionals have to decide whether to sit on the bench or merge with each other to keep pace?

Five Regional Banks That Could Be Acquired:

• Fifth Third: commercial and retail engine across the Midwest and a fast-growing Southeastern footprint
• Huntington: low-cost deposit base alongside a growing branch presence in high-growth markets in Texas and the Carolinas
• Citizens: dense retail and commercial coverage across affluent Mid-Atlantic and New England cities
• KeyCorp: middle-market commercial business and branches stretching from the Great Lakes to the Pacific Northwest
• Regions: retail deposit footprint in the fast-growing Southern corridor, including Texas and Florida

Why Mergers Matter:

• Unlocking scale and cost-cutting opportunities
• Enhancing branch networks and deposit bases
• Improving competitiveness in a rapidly changing market

The Future of Regional Bank Mergers:

The moment is still favorable for mergers, but few banks are eager to sell. The consolidation of regional banks will create new opportunities for megabanks to grow and expand their reach.
