UBS Could Leave Switzerland. But Would It Actually Be Worth It?

UBS has just reported USD 2.7 billion in quarterly profit. Its wealth-management clients brought in USD 55.1 billion of net new assets. Yet alongside that commercial momentum sits a question few countries would welcome about their largest bank: could it be better off headquartered somewhere else?

The third-quarter results, released on 28 October, show a business generating substantial earnings. The argument with Bern concerns how much capital should support that business in future, and who should bear the risks when it encounters trouble.

UBS has announced no decision to leave Switzerland. Relocation remains a contingency discussed in reporting. Its economic merits are considerably harder to establish than its political significance.

The debate sharpened with the results: Reuters reported that CEO Sergio Ermotti said UBS was assessing its long-term ability to compete from Switzerland, while stressing there was no rush to act.

Credit Suisse’s emergency takeover in March 2023 explains the urgency. FINMA’s subsequent review identified management failures and lost confidence, followed by destabilising withdrawals. It also identified the parent bank as the group’s weakest link in capital adequacy. Capital and liquidity were both part of the problem; neither alone explains the collapse.

The Federal Council’s April proposal would require Swiss systemically important banks to back the carrying value of relevant foreign participations fully with Common Equity Tier 1 capital at the parent bank. In practice, those investments would be deducted from the parent’s CET1.

CET1 principally comprises ordinary shareholders’ equity and retained earnings, after regulatory adjustments. It absorbs losses while a bank continues operating. It is a source of financing, rather than a separate pot of cash gathering dust.

The Swiss National Bank argues that full backing would stop losses on foreign participations undermining the Swiss parent’s capital position, making recovery measures easier. FINMA supports the reform, while stressing the need for stronger preventive powers too.

The Council of States approved 90% backing on 23 September, rather than the government’s 100%. This is a requirement against participations, not a proposal for UBS’s group capital ratio to reach 90%.

UBS’s September calculation puts the additional CET1 needed at UBS AG at approximately USD 16 billion for that proposal, plus about USD 2 billion from ordinance measures. That explains the USD 18 billion figure. Separately, it identifies roughly USD 15 billion under existing regulations following the Credit Suisse acquisition.

Under the full-backing proposal, UBS’s April estimate was USD 20 billion for foreign participations alone. The government estimated approximately USD 20 billion of parent-bank strengthening overall, but only around USD 9 billion of actual shortfall had its package applied on 1 January 2026. Its explanation points to existing capital buffers. These are estimates of requirements and funding needs, not interchangeable invoices.

UBS argues the measures would damage competitiveness. The financial mechanism is straightforward: if earnings remain unchanged while the equity supporting them rises, the return on that equity falls. Retaining more profits can also leave less available for distributions during the build-up. Neither mechanism establishes the eventual share-price effect.

The latest results show reported return on CET1 of 14.8%, or 16.7% on UBS’s underlying measure, which excludes selected items. Its CET1 capital ratio was 14.7%. A consolidated ratio, however, cannot by itself answer how much capital a particular legal entity needs.

Reuters reported on 16 October, citing three people familiar with the matter, that UBS was examining scenarios including relocation and mergers. Its sources said no active talks were underway. London and the United States have entered the discussion; neither represents an approved destination.

America offers a growth rationale beyond regulation: UBS Bank USA’s national-bank conversion received final approval on 20 March, according to its first-quarter report. That supports expanding banking services there; it is not approval for relocating the group. Reuters’s October report also relayed Financial Times reporting of British government discussions with UBS about London.

An exclusive Reuters report on 29 October, based on an internal Swiss government assessment, describes substantial obstacles. Under a flat US holding structure, restrictions on debt-funded subsidiary equity and holding-company liabilities could absorb capital comparable to full backing of domestic and foreign units. Retaining UBS’s present parent-bank structure, if US authorities accepted it, could allow some relief. The assessment did not specifically examine merger routes.

For Britain, Reuters reported potentially softer treatment of foreign subsidiaries, offset by greater capital needs against the Swiss operation. We have not obtained the underlying assessment; its conclusions remain the government’s analysis as reported by Reuters.

The broader point is that regulatory treatment follows legal structure as well as geography. Federal Reserve rules constrain certain liabilities and activities at US global systemically important bank holding companies. A new domicile would require a credible structure acceptable to the relevant authorities.

Potential strategic benefits deserve consideration: closer alignment with a major business market, or a structure permitting capital to be used more efficiently. Against them, a transaction would need to resolve tax treatment, funding arrangements, contracts and operational continuity. Client retention and the value of Swiss identity would also need testing. No verified public budget establishes the net relocation cost.

The Swiss domestic business would remain an economic commitment requiring financing and supervision. Moving a headquarters would not remove its customers, loans or risks.

Johann Scholtz, a Morningstar DBRS bank analyst, told S&P Global Market Intelligence that shifting the holding company alone would leave UBS AG subject to Swiss standalone capital requirements. That distinction matters: changing ownership above the bank and moving businesses out of it are different transactions.

The decisive comparison is the value of future distributable earnings under each structure. Extra CET1 is not an expense equal to its face value: shareholders still own the bank financed by it. Its economic burden depends on returns earned, financing costs and opportunities forgone.

A move would therefore need lasting benefits large enough to outweigh transaction costs, disruption and any new capital constraints. Without a host-regulator-approved structure and a comparable financial model, a confident numerical verdict is unavailable.

Staying under tougher rules could depress capital efficiency while improving resilience. A compromise could preserve more distribution capacity and reduce uncertainty, although its effectiveness in a crisis would still need scrutiny. Relocation could improve flexibility, but expose shareholders to execution risks and a different regulatory bargain.

Management must consider those options. Taxpayers have a different priority: limiting another rescue. Switzerland’s wider economy has interests in lending, employment and financial services that do not map neatly onto UBS’s shareholder return.

The National Council committee’s 28 October update records agreement to consider the bill, with no further decisions. Detailed deliberations are planned for 23–24 November; National Council consideration is expected in the winter session. The final law remains unsettled.

Investors should also watch UBS’s February 2027 results, when it plans to announce 2027 capital-return ambitions. The bank currently intends to finish its USD 3 billion buyback programme by its fourth-quarter results; repurchase timing and amounts remain conditional, including on parliamentary visibility.

Track parent-bank capital disclosures alongside group ratios, dividend and buyback guidance, and wealth-management flows: a more flexible structure would offer little comfort if clients left.

Leaving could be worthwhile under a demonstrably better structure. The evidence so far establishes a reason to investigate that option, rather than a financial case for executing it. UBS’s strongest argument would be a credible improvement in what shareholders can earn and receive after all the new constraints are counted.
