$12.2B Santander Webster Bank Deal Wins OCC Nod, Fed Looms

Banco Santander’s $12.2 billion Webster Bank acquisition cleared OCC approval on Friday, June 12, removing a key regulatory obstacle while leaving the Federal Reserve Board and European Central Bank still in the path to closing. Webster Financial, the holding company for Connecticut-headquartered Webster Bank, disclosed the approval in an SEC filing, according to PYMNTS.

The Office of the Comptroller of the Currency approved the application for the bank merger, but the deal is not done. Webster said the acquisition remains subject to customary closing conditions, including approvals from the Federal Reserve Board and the European Central Bank, according to the filing.

OCC approval moves the Santander Webster Bank acquisition into its final regulatory stretch

The Santander Webster Bank acquisition has now passed one of the clearest regulatory checkpoints in the transaction. The OCC’s approval matters because it moves the proposed bank merger out of the application stage at that agency and into a narrower closing process.

Santander announced the deal on Feb. 3, saying the acquisition would create a combined business ranking as a top 10 retail and commercial bank in the United States by assets and a top five deposit franchise across key states in the Northeast. Santander said at the time that it expected the transaction to close in the second half, subject to customary closing conditions.

The transaction terms give Webster shareholders $48.75 per Webster share in cash and 2.0548 Santander shares in the form of American Depositary Shares per Webster share, representing $26.25 per Webster share based on the volume-weighted average price of €10.79 per Santander share for the three-day period ended on 2 February 2026, and a EUR/USD exchange ratio of 1.1840 as of 2 February 2026. That totals $75 per Webster share, according to Santander’s announcement.

XOOMAR analysis: The OCC approval doesn’t guarantee completion. It does change the risk profile. The central question is no longer whether the merger can clear this agency. It’s whether the remaining regulators and closing conditions move on Santander’s expected timetable.

Webster gives Santander a bigger Northeast deposit and commercial banking base

Webster is valuable to Santander because it brings a U.S. regional banking franchise centered in the Northeast, with commercial relationships and a deposit base Santander has explicitly called strategic. Santander said the combination would pair its consumer finance business with Webster’s commercial franchise and high-quality deposit base.

For customers, Santander said the combined business would offer a broader branch and service footprint, enhanced digital and mobile banking capabilities, expanded product offerings, and local relationship-based service backed by one of the world’s largest banking groups.

That’s the operating case. Santander is buying scale, deposits, and commercial banking depth in a market where branch presence and client relationships still matter. The company has also tied the deal to profitability targets, saying Webster would help Santander’s U.S. return on tangible equity reach 18% by 2028 and its efficiency ratio fall below 40%.

Webster CEO John R. Ciulla framed the transaction as a client and growth move in the company’s April 28 earnings release.

“Our proposed transaction with Banco Santander will enhance our ability to support our clients and the communities we serve, while unlocking new opportunities for growth,” Ciulla said. “We are making significant progress planning for the integration of two highly complementary banking organizations.”

Santander Executive Chair Ana Botín used similar language in a March 27 release after Santander shareholders approved a capital increase required for the acquisition.

“The combination of Santander’s leadership in consumer finance with Webster’s commercial franchise and its high-quality deposit base positions us as a well-diversified regional bank and will enable us to capture new growth opportunities and generate synergies.”

The Santander Webster Bank acquisition also comes with a leadership plan. Santander said Christiana Riley will remain Santander’s country head in the U.S. and Santander Holdings USA CEO. Ciulla will be CEO of Santander Bank NA, into which Webster’s businesses will be integrated. Luis Massiani, Webster’s president and chief operating officer, will be COO of both Santander Holdings USA and Santander Bank NA, with responsibility for leading integration.

Those are separate stories, but they frame why execution after a financial-services deal can matter as much as the headline price.

Remaining approvals will decide whether Santander hits its second-half closing target

The deal still needs to satisfy customary closing conditions. The named remaining approvals in Webster’s filing are the Federal Reserve Board and the European Central Bank.

That leaves several practical questions for investors and customers. Santander and Webster have laid out the strategic case, the leadership structure, and the broad customer promise. They have not, in the supplied materials, detailed final branch plans, employee impacts, customer migration timing, or the exact technology integration sequence.

Those details matter because bank integrations are judged in daily customer contact: deposits staying put, digital access working, commercial clients getting clear answers, and staff knowing which systems and brands survive the handoff.

XOOMAR analysis: The OCC approval makes the Santander Webster Bank acquisition harder to dismiss as just an announced transaction waiting on regulators. It is now a live closing process with fewer visible gates. The next signal to watch is whether Santander and Webster provide firmer timing around the remaining approvals and integration plan before the second-half closing window narrows.
