UBS Plans for Contingencies as London Courts Its Headquarters

The UK government has pitched London as a new home for UBS, while the bank says its base stays in Zurich and reportedly examined a move of its legal base.

The UK government tried to persuade UBS to move its headquarters and stock-market listing to London, the Financial Times reported on October 16, 2026. According to the paper, Rachel Reeves, while she was chancellor, raised the idea with UBS chairman Colm Kelleher, and the most recent discussion took place earlier this year.

The approach lands on top of a question inside UBS itself. The FT and Reuters reported in late 2025 that the bank had examined moving its legal base as contingency planning, a step linked to Swiss capital rules that UBS has criticized. The Treasury did not comment on those reports.

UBS has said it intends to stay in Switzerland and run the group from Zurich. That public position sits alongside the reported contingency work, and the tension between the two is the center of this story: a bank can keep its headquarters in Zurich while its planners test the alternatives.

Neither Reeves nor UBS commented to the FT. The UK Treasury did not respond to a request for comment, and the Swiss government did not comment. No public reply from Kelleher has been reported, so the pitch is, for now, an account of private conversations rather than a stated government policy.

The question has reached Washington too. In December 2025, Senator Elizabeth Warren, the ranking Democrat on the Senate Banking Committee, wrote to Treasury Secretary Scott Bessent asking whether he had discussed redomiciling UBS with its executives. Her letter, dated December 9, 2025, asked whether any official had promised favorable regulatory treatment in exchange for a move.

What London is offering

London's case rests on the bank's existing footprint in the UK. A headquarters is more than a mailing address. It brings boards, senior hires, legal and audit work, and the spending that follows a large employer, from office leases to professional services. For a city competing for global finance, the prize is less the letterhead than the jobs that would sit in the same building as the people making the decisions.

The tax question behind the pitch

There is a second thread. Chancellor John Healey is weighing a higher tax on UK bank profits ahead of the Budget. The Press Association reported on October 1, 2026 that he has summoned the chief executives of the largest UK banks to a meeting before the Budget, and the industry has argued that a higher bank tax would push business out of the UK. The government has not said what it will do. A bank comparing London with Zurich will price any such change into its decision, alongside the capital rules Switzerland is weighing.

Tax and capital rules are now the terms on which financial centers compete. A bank does not move for a pitch alone. It moves when the total cost of the new address, in taxes, capital and staff, beats the cost of staying put.

The Caribbean angle

The lesson carries south. The Ledger reported on September 24, 2026 that Bermuda's company count fell to a four-year low as a new tax took hold, a reminder that a tax change can move corporate presence faster than a speech can. Caribbean financial centers that compete for regulated firms face the same arithmetic. The rules a government writes can decide where a company puts its legal address, its staff and its board.

For the region's regulators and finance ministers, the UBS episode offers a plain test. Any offer to a bank has to be weighed against what it costs the public budget and the local tax base, and against what happens if the bank decides to stay. London's pitch, if it is made in earnest, is a bet that the reward for hosting a global bank exceeds the cost of changing the rules to win it.

What to watch: any statement from UBS or Kelleher, a reply from the Treasury, the Swiss capital decision, and the October 28 Budget.
