UBS weighs its future as Switzerland debates tougher bank rules

A proposed $16 billion capital charge has put UBS’s Swiss headquarters at the centre of a national argument over financial security. The Council of States backed tougher rules designed to prevent a repeat of the 2023 collapse of Credit Suisse, which UBS acquired in a rescue organised with state support.

The legislation still needs approval from the National Council, the lower house of the Federal Assembly. UBS executives nevertheless expect the political momentum to continue. The bank now faces a choice between carrying a much larger capital buffer, changing the shape of its international business, or reconsidering its legal home.

The stakes reach beyond UBS’s boardroom. The bank’s balance sheet is substantially larger than Switzerland’s economy, a scale that has intensified concern about the risks to taxpayers if another crisis were to require public intervention. The proposed rules aim to make UBS more resilient, while investors fear that the cost could weaken returns and reduce the group’s competitiveness.

Chair Colm Kelleher has acknowledged that UBS may rethink its Swiss base if the final framework becomes too demanding. That warning has turned a regulatory debate into a question about the future of Switzerland’s most important bank.

UBS investors are openly challenging Switzerland’s appeal as a base for global banking. Artisan Partners, a top-10 shareholder, wrote to the board last week to say that the country was “no longer an attractive or desirable location” for the largest Swiss lender. Cevian Capital, which owns about 1.5% of UBS, issued a similar warning last year.

The criticism reflects the unusual size of the group. UBS combines a major Swiss domestic franchise with one of the world’s largest international wealth-management businesses. Its balance sheet exceeds the size of Switzerland’s economy, making the bank systemically important at home and unusually exposed to rules tailored to the country’s ability to absorb a banking failure.

Investors have identified the United States as one possible destination because its capital framework is viewed as less stringent. A large eurozone economy, such as Germany, could offer a closer European base. The United Kingdom appears less attractive because its capital requirements are closer to Switzerland’s. Several governments have raised relocation with UBS in recent years, according to a person familiar with the matter.

A move would carry political and financial costs. Morgan Stanley analysts estimate that an exit tax could reach $10 billion, while Karin Keller-Sutter says leaving would be more expensive and legally more complex than accepting the reforms.

A foreign transaction could give UBS a route around Switzerland’s tougher capital regime. One option under discussion is a deal with an overseas bank after the integration of Credit Suisse is complete. UBS expects that process to remove much of the acquisition burden and lift profits, giving management greater flexibility.

A reverse takeover could involve a smaller foreign bank, potentially in the United States, acquiring UBS in an all-share transaction. UBS shareholders could still hold a majority of the combined group. Morgan Stanley analyst Giulia Aurora Miotto said such a structure might avoid the exit tax, although it would require a smaller bank to merge with UBS and potentially surrender control of the enlarged institution.

A larger merger with a Wall Street or European bank is another possibility. Morgan Stanley has attracted attention because Kelleher spent much of his career there, and because the two groups would combine major wealth-management franchises. The Financial Times reported no indication that either bank is pursuing such a transaction.

The strategy would also bring regulatory scrutiny in several jurisdictions, as well as difficult questions over governance, ownership and the location of key businesses. For now, the idea remains a contingency plan rather than an announced negotiation. UBS must first complete the Credit Suisse integration and see the final shape of the Swiss rules.

A two-part UBS could preserve the Swiss domestic bank while moving international operations beyond the reach of the new rules. A senior executive at a rival European bank told the Financial Times that splitting the group would be the preferred option if they were in UBS’s position.

The logic is straightforward. UBS’s Swiss business serves households, companies and the domestic economy, while the group’s international operations generate much of its global scale and complexity. A separation could leave the domestic franchise under Swiss supervision and place the international arm in another jurisdiction with a different capital framework.

Such a restructuring would be highly complex. UBS would need to divide legal entities, capital, technology systems, staff, risk controls and reporting lines. Regulators in Switzerland and abroad would have to approve the arrangements. Clients and employees would also need clarity about which entity would hold their accounts, investments and contracts.

The plan could satisfy some political demands by keeping a Swiss bank in Switzerland. It could also address shareholder concerns about the cost of holding extra capital across the entire group. Yet the structure might sacrifice some of the benefits that come from operating a single global institution, including shared funding, technology and risk management. The source material does not indicate that UBS has committed to a split.

The National Council will decide whether the proposed capital framework becomes law, and UBS must plan before that vote is complete. The debate follows the state-supported rescue of Credit Suisse and reflects a basic Swiss concern: a bank larger than the national economy must be able to withstand severe losses without relying on taxpayers.

For Switzerland, the choice carries competing risks. A tougher regime could strengthen financial stability and reassure depositors, businesses and international clients. It could also raise UBS’s funding costs, reduce returns and encourage the bank to move activities or its headquarters abroad. A departure would weaken the country’s position as a global financial centre and could affect jobs, tax receipts and the ecosystem around Zurich and Geneva.

For UBS, the decision will involve more than the headline $16 billion figure. Management must compare the cost of holding capital with the tax, legal and operational burden of relocation or a cross-border transaction. The timing matters too. The bank expects greater earnings and fewer integration costs once Credit Suisse has been absorbed, which could make structural options easier to pursue.

Keller-Sutter has made the government’s position clear: leaving Switzerland would be costly and complicated. UBS’s investors have made theirs equally clear: they want the bank to protect returns. The next stage belongs to Parliament, but the strategic review has already begun.
