UBS shareholder calls for bank to leave Switzerland

A shareholder controlling about 1.8% of UBS shares is urging Switzerland’s biggest bank to leave the country. Artisan Partners, which manages more than 60 million UBS shares for clients, says proposed capital rules have made Switzerland an unattractive base for a global lender.

The intervention arrives as Parliament debates tougher safeguards for systemically important banks after the collapse of Credit Suisse and its emergency takeover by UBS. Switzerland’s upper house has backed a proposal that UBS estimates would require $16 billion in additional common equity tier 1 capital. The measure now moves to the lower house, and a final decision is unlikely before next year.

Artisan Partners portfolio managers, including Daniel O’Keefe, set out their position in a letter to UBS’s board on Wednesday. “The simple fact is that Switzerland is no longer an attractive or desirable location for UBS,” they wrote.

The dispute places shareholder returns, financial stability and Switzerland’s economic interests in the same legislative fight. UBS employs thousands of people in Switzerland, maintains its headquarters in Zurich and remains central to the country’s financial sector. A relocation debate therefore reaches beyond the bank’s balance sheet and into the future shape of Swiss banking.

The proposed rules would force UBS to hold substantially more loss absorbing capital, according to the bank’s own estimate. The measure approved by the Swiss upper house includes a 90% core capital ratio for UBS’s foreign subsidiaries, a requirement that UBS has rejected as excessive.

The capital debate follows the Credit Suisse crisis, which exposed the consequences of a failing institution with global operations and deep links to the Swiss economy. Policymakers want a stronger buffer around UBS, the country’s only remaining global banking giant. They are also examining how a parent bank should support foreign subsidiaries during a crisis.

UBS says the parliamentary decision does not represent a compromise. The bank argues that regulation should address the causes of the Credit Suisse failure while remaining targeted, proportionate and aligned with international standards. Its concerns centre on the amount of capital tied up under the proposal and the effect on returns for shareholders.

The next stage belongs to the National Council, Switzerland’s lower house. Lawmakers could dilute the measure, amend it or retain the upper house’s approach. Until Parliament completes that process, the precise capital requirement remains unsettled. The debate has already changed the terms of UBS’s relationship with Bern, however, by making the location of the group’s headquarters a shareholder issue.

Artisan Partners puts the potential shareholder cost at roughly $36 billion in lost market capitalisation. The investor says UBS could deploy the affected capital more productively in a country with rules similar to Switzerland’s current framework, estimating a 15% return on that capital.

Those figures form the financial backbone of the call for relocation. Artisan Partners has previously pushed for strategic change at other Swiss companies, including Novartis. Its UBS letter frames the issue as a question of capital efficiency and long term competitiveness, rather than a short term disagreement over one parliamentary vote.

A move abroad would carry consequences that the letter does not quantify. UBS’s headquarters, management functions and extensive Swiss operations support employment, tax revenue, professional services and Zurich’s position as a global financial centre. The bank also has longstanding ties to Swiss institutions and households through wealth management, corporate finance and investment services.

Finance Minister Karin Keller Sutter has played down the likelihood of UBS relocating abroad, according to a separate report. Her assessment reflects the practical barriers involved in moving a global bank, even as investors calculate the value of a different regulatory base. UBS has also made clear that it will keep lobbying Parliament with its own analysis before lawmakers reach a final decision.

UBS says it will remain headquartered in Switzerland and defend its shareholders through the legislative process. A spokesperson said the bank’s goal is to “continue operating successfully as a global bank from Switzerland”, while pressing for rules that are targeted, proportionate and internationally aligned.

That position leaves room for a prolonged dispute. The National Council will review the upper house proposal, and the final package could change before it becomes law. UBS will submit further facts and analysis, focusing on the capital requirement, the treatment of foreign subsidiaries and the lessons regulators draw from the Credit Suisse collapse.

For Switzerland, the stakes include the resilience of its financial system and the competitiveness of its principal international bank. For UBS, the issue affects how much capital it can place in lending, wealth management and other businesses. For shareholders such as Artisan Partners, it is a question of whether Swiss rules impose a cost that peers in other jurisdictions do not face.

The relocation threat has sharpened the political debate, but it has not produced a relocation plan. UBS remains in Zurich, Parliament has yet to settle the rules and the bank continues to argue that Switzerland can host a global institution while maintaining credible safeguards. The next decision will come from the lower house, followed by further negotiations over the final legislation.
