Overview
Updated Aug 29Spain's Banco Santander closed its $12.3 billion purchase of Webster Financial on August 20, folding Connecticut's Webster Bank into its US operations. The merged bank has about 8 million customers and more than 550 branches, with its US headquarters in Boston. Santander counts it at $327 billion in assets; the Federal Reserve, using a narrower holding-company measure, said $253.6 billion.
Integration is just starting, and customers see little change for now. Brands and systems stay unchanged for at least a year; a single platform under the Santander name is planned by the end of 2027. Santander targets $800 million in annual savings by 2028, and deposits from the two banks keep separate FDIC coverage for six months.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
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.
Santander gained a Northeast branch network and rebranded it under its own name.
The US arm leaned on auto and consumer lending, with uneven profits, setting up the search for scale that led to Webster.
Webster is the follow-on that Santander has wanted for over a decade to make its US bank big enough to pay off.
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.
PNC absorbed BBVA's US branches and became one of the largest US banks. BBVA exited retail banking in the country.
The sale became a symbol of European banks struggling to profit in US retail and choosing to leave.
Santander is expanding into the same market its Spanish rival abandoned, testing whether scale can succeed where BBVA gave up.
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.
HSBC transferred branches to Citizens Bank and Cathay Bank and shrank its US footprint.
It reinforced the pattern of large foreign banks retreating from US consumer banking.
Santander is buying deeper into the US retail market that HSBC and others decided to leave.
