Banco Santander completed its acquisition of Webster Financial Corporation, the parent company of Webster Bank. The completion was reported to the Comisión Nacional del Mercado de Valores (CNMV) on the morning of the announcement, after the relevant regulators in the US and Europe had approved the transaction. The purchase price is around 10.5 billion euros; the agreed consideration comprises 65 per cent cash and 35 per cent newly issued Santander shares, for which the group carried out a capital increase. In Madrid, the share price fell by around 0.8 per cent at the start of trading.
With the acquisition, Santander joins the ranks of the ten largest retail and commercial banks in the United States by assets. This reflects the institution’s ranking based on the combined balance sheet. The Federal Reserve gave its approval in early August, while the Europäische Zentralbank followed in July. The transaction was announced in February 2026.
Strategically, Webster gives Santander a strong foothold in New England and additional stable sources of deposits. Particular emphasis is placed on the business in Health-Savings-Accounts, which promise low-cost funding and recurring revenue. The group expects cost synergies and efficiency gains from the integration; the RoTE (Return on Tangible Equity) in its US business is also expected to improve by 2028. These expectations come from company statements and should be treated as forecasts.
Operationally, Webster is planned to be integrated into Santander’s US unit; the bank’s business will be transferred to Santander Bank, N.A. and systems will be harmonised gradually. Santander initially provided only a broad outline of specific timelines and organisational changes.
Regulatory consequences are foreseeable: with a larger presence in the US market, the American subsidiaries will face a stricter regime, including an annual Federal Reserve stress test. This increases governance and reporting requirements, but may strengthen the group’s market access and profile in the US over the medium term. Key risks include the effort involved in integration, possible operational friction, and US interest-rate and credit cycles, which can affect earnings and credit quality.
Statements from Banco Santander, the Federal Reserve and the CNMV confirm completion and the main details; independent financial statements and regulatory publications will show the transaction’s impact over the coming quarters.
