Wells Fargo and Citigroup are among the few U.S. megabanks able to acquire a large regional bank under current deposit caps, but rising profits and stock prices mean few sellers are eager to make a deal
After years of regulatory barriers, the landscape for major U.S. bank mergers has shifted, putting Wells Fargo and Citigroup in a rare position to pursue large acquisitions. Both banks remain below the 10% national deposit cap that blocks rivals like JPMorgan Chase and Bank of America from buying another major lender. This regulatory headroom, combined with a more permissive stance from federal agencies, has reignited speculation about which regional banks could become targets for a transformative deal.
According to reporting by CNBC, the Trump administration's approach to bank mergers and recent congressional actions have lowered hurdles for large-scale consolidation. The Federal Deposit Insurance Corporation has reinstated expedited merger reviews, and the Office of the Comptroller of the Currency has rolled back some Biden-era restrictions. These changes have made it possible for banks like Wells Fargo and Citigroup-previously limited by consent orders and growth caps-to consider deals that would have been off-limits just a few years ago.
Potential Targets
For a deal to make sense, a target must be large enough to impact the acquirer's business but not so big that it pushes the buyer over the 10% deposit threshold. Analysts and investment bankers point to five regional banks that fit these criteria: Fifth Third, Huntington, Citizens, KeyCorp, and Regions. Each offers a distinct geographic footprint and deposit base. Fifth Third is strong in the Midwest and Southeast, Huntington is expanding in Texas and the Carolinas, Citizens covers affluent cities in the Northeast, KeyCorp stretches from the Great Lakes to the Pacific Northwest, and Regions is anchored in the South, including Texas and Florida.
Beyond these, Zions could be a fit for Wells Fargo, given its presence in high-growth Western states, while First Horizon's Sunbelt footprint may appeal to Citigroup. Still, most regional banks have declined to comment on potential deals, and both Wells Fargo and Citigroup have publicly emphasized organic growth over acquisitions, at least for now.
Deal Economics and Market Dynamics
Despite the regulatory green light, actual deal activity has lagged expectations. In the first half of 2026, the value of North American bank mergers dropped to $30.1 billion, less than half the total from the same period a year earlier, based on EY data. Rising profits and strong stock prices have made regional banks less willing to sell, as executives weigh the benefits of a merger against the potential returns from share buybacks and continued independent growth. Activist investors have also pushed for greater discipline, forcing management teams to justify any acquisition against alternative uses of capital.
For Citigroup, acquiring a large regional bank could provide a much-needed boost to its U.S. deposit base, which remains smaller than its peers. However, integrating a major lender would add complexity, technology challenges, and operational risk at a time when Citigroup is still working to streamline its business. Wells Fargo, with a larger branch network and stronger stock currency, may be better positioned to pursue a deal if the right opportunity arises, but has signaled it will only act if the economics are compelling.
Industry Consolidation Outlook
While the current environment is favorable for mergers, the expected wave of consolidation has yet to materialize. Many regional banks see themselves as buyers rather than sellers, and the economics of a deal must overcome high valuations and strong earnings. Some analysts believe that if Wells Fargo and Citigroup remain on the sidelines, regional banks may instead look to merge with each other to achieve the scale needed to compete with the largest U.S. lenders. Bain & Company projects that by 2030, mergers among regionals could create one to three new megabanks with at least $1 trillion in assets, shrinking the number of regional banks from 49 to as few as 30.
For now, the race for scale continues, with regulatory conditions more favorable than they have been in over a decade. Whether Wells Fargo, Citigroup, or a pair of regionals will make the next big move remains an open question, but the window for transformative deals may not stay open indefinitely.
According to the Federal Deposit Insurance Corporation, as of March 2026, Wells Fargo held approximately 8.5% of total U.S. deposits, while Citigroup accounted for about 6.2%. The five regional banks most often cited as potential targets-Fifth Third, Huntington, Citizens, KeyCorp, and Regions-each manage between $150 billion and $190 billion in assets, making them large enough to matter but small enough to keep an acquirer under the regulatory cap. The overall number of U.S. commercial banks has continued to decline, falling below 4,200 in 2026, reflecting ongoing industry consolidation.
Deposit caps play a central role in shaping U.S. bank mergers. The 10% national deposit limit, established under the Riegle-Neal Act, is designed to prevent any single bank from dominating the country's deposit base. While this rule blocks the largest banks from further expansion through acquisition, it leaves room for others to grow-if they can find willing sellers. For regional banks, the decision to merge or remain independent often comes down to whether the benefits of scale, technology investment, and cost savings outweigh the risks of integration and cultural fit. As the industry evolves, these trade-offs will continue to drive both strategy and dealmaking.
