A recent regulatory shift has reopened the door to large bank takeovers, and two megabanks — Citigroup and Wells Fargo — are among the few with room under the federal caps to attempt a major acquisition. Such a purchase would reshape branch networks and deposit bases and could accelerate consolidation across U.S. regional banking.
Who can move — and why now
JPMorgan Chase and Bank of America are effectively blocked from buying another big bank because each already controls more than 10% of national deposits. That leaves Citigroup and Wells Fargo as the most plausible candidates to pursue a sizeable regional lender, according to bankers, consultants and investors.

Both Citi and Wells spent years constrained by regulatory limits — Citigroup by consent orders, Wells by enforced growth caps — but have recently cleared several hurdles and are back in growth mode. A major acquisition could instantly add thousands of branches and billions in deposits. For Citigroup, which operates roughly 650 U.S. branches, a purchase could supply cheaper funding. For Wells Fargo, an acquisition would boost scale and create opportunities for expense reductions.
“Two years ago, it was impossible for a bank of that size to get approval to acquire almost anything,” said Brian Graham, co-founder of advisory firm Klaros. “Now, it’s possible they can get a deal done. I’d be shocked if they aren’t exploring it.”
Potential targets in play
Few of the more than 4,200 U.S. banks meet the size and strategic fit required to move the needle without pushing an acquirer past the deposit cap. Investment screens identify a short list of regional institutions that could appeal to either Citi or Wells.
- Fifth Third — strong commercial and retail franchise across the Midwest, expanding in the Southeast.
- Huntington — low-cost deposits and a growing branch footprint in fast-growing Texas and the Carolinas.
- Citizens — dense retail and commercial coverage in affluent Mid‑Atlantic and New England markets.
- KeyCorp — middle-market commercial business with branches from the Great Lakes to the Pacific Northwest.
- Regions — retail deposit presence across the fast-growing Southern corridor, including Texas and Florida.
Analysts also single out a few single-target fits: Zions could be attractive particularly to Wells Fargo because of its ties across high-growth Western states, while First Horizon’s Sunbelt footprint might appeal to Citigroup.
Wells Fargo and Citigroup declined to comment. Most regional banks on the list also declined; Zions and First Horizon did not respond to requests.
Leadership signals and investor pressure
Citi CEO Jane Fraser has publicly emphasized organic growth over deal-making. Still, a March Bloomberg report said Citi executives discussed buying a major regional to bolster deposits — a report Citi called “baseless speculation.” The stock fell more than 4% on the day of that coverage.
Analysts warn that a large depository deal carries integration risks at a time when Citi is trying to simplify its operations. “A depository deal would be a major distraction,” said KBW analyst Chris McGratty.
Wells Fargo’s CEO Charlie Scharf, by contrast, has signaled openness to transformative transactions while also stressing organic growth. “We should always consider ways to increase franchise value, including M&A,” Scharf wrote in a March shareholder letter, adding that “if a great opportunity exists, we will look at it.”
At the same time, rising profitability and strong share prices have made many banks reluctant to sell. Frank Sorrentino, a mergers banker at Stephens, said the market’s strength raises the threshold for sellers. “Most companies have good profit margins, stock prices are really good, and it just raises the bar if they are going to sell,” he said. “Everybody thinks they’re a buyer, not a seller.”
Regulatory backdrop and deal economics
Regulators have recently eased the path for bank deals. In the past year, Congress rolled back Biden-era merger restrictions at the Office of the Comptroller of the Currency, and the FDIC restored long-standing merger guidelines that streamline reviews and lower the bar for approval.
Still, the expected surge in consolidation has not yet arrived. EY data show the value of North American bank mergers dropped to about $30.1 billion in the first half of 2026 — more than a 50% decline from the year-earlier period. The explanation is partly economic: many boards and activist investors now weigh acquisitions against share buybacks and other uses of capital, tightening discipline around M&A.
Regional consolidation as Plan B
If Citigroup and Wells Fargo opt not to pursue a major target, regional banks face their own strategic choice: grow independently or consolidate among themselves. Some bankers have long speculated that combinations among large super-regionals could create new challengers to the current giants.
Consulting firm Bain projects that mergers among regionals could produce one to three new megabanks with at least $1 trillion in assets by 2030, and reduce the number of regional banks substantially. “We expect more banks, particularly regional players, to use M&A to add capabilities,” Bain said, specifically noting technology and artificial intelligence as drivers of deal rationale.
With regulators more receptive and industry executives under pressure to boost scale and capabilities, the next wave of U.S. bank consolidation may come from multiple directions — whether from a bold move by a megabank or through a string of regional combinations. The timing and winners, however, remain uncertain.
