Key Takeaways
- Wells Fargo and Citigroup can pursue large bank acquisitions.
- Both banks have indicated differing strategies regarding mergers.
- Regulatory barriers have eased, yet merger activity has declined.
- Several regional banks are potential targets for acquisition.
Room for Growth
Wells Fargo and Citigroup stand out among U.S. megabanks as the only ones with the capacity to acquire a large regional bank under the 10% national deposit cap. However, neither has yet taken action. Wells Fargo’s CEO, Charlie Scharf, has expressed a willingness to consider a “transformative deal,” while Citigroup’s CEO, Jane Fraser, maintains that the bank’s focus remains on organic growth rather than mergers and acquisitions.
Current Market Dynamics
Despite a more favorable regulatory environment, the total value of bank mergers in North America plummeted by over 50% in the first half of 2026, according to EY. Analysts from Bain predict that the number of regional banks could shrink from 49 to as few as 30 by 2030, potentially leading to the emergence of one to three new megabanks with assets exceeding $1 trillion.
Potential Acquisition Targets
While there are more than 4,200 banks in the U.S., only a select few would be suitable for acquisition by Wells Fargo or Citigroup. A target must be large enough to make a significant impact but small enough to keep the acquirer below the 10% cap. Additionally, a compatible branch network and quality deposits are essential. Based on these criteria, five regional banks emerge as strong candidates:
- Fifth Third, with a solid presence in the Midwest and a growing footprint in the Southeast.
- Huntington, known for its low-cost deposits and expansion in Texas and the Carolinas.
- Citizens, which has extensive coverage in affluent Mid-Atlantic and New England areas.
- KeyCorp, with branches from the Great Lakes to the Pacific Northwest.
- Regions, offering a retail deposit base in the rapidly growing Southern corridor.
For Wells Fargo, Zions could be a fitting target due to its relationships in high-growth Western states. Citigroup might find First Horizon appealing, given its presence in the expanding U.S. Sunbelt.
Strategic Considerations
When asked about the possibility of acquiring a large bank, Jane Fraser reiterated Citigroup’s commitment to organic growth. However, discussions have reportedly occurred within the bank about acquiring a major regional lender to enhance its deposit base, although Citigroup has dismissed such speculation as unfounded.
Analysts believe that Citigroup is still working to demonstrate that its internal strategies can yield better returns. Acquiring a large regional bank could complicate matters by introducing additional branches, employees, and integration risks at a time when the bank is focused on simplification.
Conversely, Charlie Scharf has indicated a readiness to explore transformative deals, including potential acquisitions, while also emphasizing the importance of organic growth. He acknowledged in a shareholder letter that regulatory attitudes have become more favorable towards such transactions.
Market Conditions
Despite the favorable conditions for mergers, the anticipated wave of consolidation has yet to materialize. The value of North American bank mergers fell to $30.1 billion in the first half of 2026, a significant drop compared to the previous year. While regulatory hurdles may be diminishing, many banks are reluctant to sell when their profits and stock prices are on the rise.
As activist investors push for improved shareholder returns, bank executives are increasingly weighing the benefits of acquisitions against stock buybacks, leading to a more cautious approach to mergers.
Future Outlook
Experts believe the current environment is conducive to mergers, with some describing it as the best since the financial crisis. Recent legislative changes have relaxed merger restrictions, allowing for expedited reviews and lowering the bar for regulatory approval.
Wells Fargo possesses a stronger stock currency than Citigroup, which could facilitate justifying a deal, especially if it addresses a geographic or product gap. Alternatively, regional banks may consider merging with one another to remain competitive if Wells Fargo and Citigroup choose not to pursue acquisitions.
Bain’s research suggests that mergers among regional banks could lead to the formation of new megabanks by 2030, as the industry continues to evolve and adapt to changing market conditions.
