Spain's largest bank completes its $12.3 billion purchase of Connecticut's Webster Financial

Today: Merger takes legal effect

Overview

Updated 1 hour ago

For years, Europe's big banks have found the United States hard to crack, and several have simply left. On August 20, 2026, Spain's Banco Santander went the other way. It closed a $12.3 billion purchase of Webster Financial, the Connecticut lender behind Webster Bank.

The deal makes Santander's US arm the country's 19th-largest bank, with about $253.6 billion in assets and the top deposit share in Connecticut. It is the biggest US bank takeover of 2026 and a bet that a European owner can build a lasting American retail and commercial franchise.

Why it matters

A European bank is expanding into US branch banking just as rivals retreat, testing whether foreign owners can compete for American depositors and businesses.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

January 2009

Santander acquires Sovereign Bancorp (2009)

Santander completed its takeover of Sovereign Bancorp, a struggling Northeast US lender, during the financial crisis. It was Santander's entry into American retail banking and cost a fraction of Sovereign's earlier value.

Then

Santander gained a Northeast branch network and rebranded it under its own name.

Now

The US arm leaned on auto and consumer lending, with uneven profits, setting up the search for scale that led to Webster.

Why this matters now

Webster is the follow-on that Santander has wanted for over a decade to make its US bank big enough to pay off.

November 2020

BBVA sells US retail unit to PNC (2020)

Spain's BBVA agreed to sell its US retail banking arm to PNC Financial for about $11.6 billion. BBVA had spent years and billions building a US branch network, mostly in the Sunbelt, but decided it could not earn enough to justify staying.

Then

PNC absorbed BBVA's US branches and became one of the largest US banks. BBVA exited retail banking in the country.

Now

The sale became a symbol of European banks struggling to profit in US retail and choosing to leave.

Why this matters now

Santander is expanding into the same market its Spanish rival abandoned, testing whether scale can succeed where BBVA gave up.

May 2021

HSBC exits US retail banking (2021)

Britain's HSBC agreed to sell or wind down most of its US retail branches, ending a long effort to compete for American consumers. It kept only a small wealth and international-banking presence.

Then

HSBC transferred branches to Citizens Bank and Cathay Bank and shrank its US footprint.

Now

It reinforced the pattern of large foreign banks retreating from US consumer banking.

Why this matters now

Santander is buying deeper into the US retail market that HSBC and others decided to leave.
