UBS wins capital requirements victory

By the Editorial Team · Tuesday, September 1, 2026

Swiss lawmakers have backed a weakened version of proposed capital rules requiring UBS to partially meet foreign subsidiary capital requirements with additional tier 1 bonds instead of only the highest-quality common equity tier one capital. This compromise reduces the regulatory burden on UBS while raising concerns about systemic risk and sets the stage for further parliamentary debates that will determine the final framework.

UBS has secured a significant setback for proposed Swiss banking regulations after influential lawmakers supported a diluted version of capital requirements impacting the country’s largest bank. The revised approach would halve the amount of the highest-quality capital UBS must hold against its foreign subsidiaries, easing the burden on its Swiss parent company.

At the centre of the dispute is a federal government proposal requiring UBS to fully capitalise its overseas entities with common equity tier one (CET1) capital — the most stringent and costly form of bank capital. This measure was introduced as part of a broader regulatory overhaul following the 2023 collapse of Credit Suisse. UBS ultimately acquired Credit Suisse in a crisis-managed rescue orchestrated by Swiss authorities, highlighting vulnerabilities in the country’s “too big to fail” framework.

Under the compromise endorsed by the parliamentary committee, UBS would still have to wholly back its foreign subsidiaries but could comply by meeting up to half of the requirement with additional tier 1 (AT1) bonds instead of CET1 capital. Analysts at JPMorgan estimate that, under this model, UBS would need to raise approximately $400 million in extra CET1 capital alongside around $16 billion in new AT1 bonds.

UBS and its CEO Sergio Ermotti have argued that the government’s initial proposal was excessive and disproportionate, warning that it could undermine the bank’s competitiveness internationally and erode Switzerland’s status as a global financial hub. The bank said the original plan would have compelled it to hold about $20 billion in additional capital, which it deemed out of line with international regulatory standards.

Swiss authorities maintain that fully capitalising foreign subsidiaries helps shield the Swiss parent from losses arising abroad and addresses systemic risks revealed by the Credit Suisse crisis. Bern contends these changes are essential to strengthen the resilience of large banks with significant international operations, including in the United States and Asia.

However, the use of AT1 bonds remains controversial in Switzerland. Regulators wrote off roughly SFr16 billion of AT1 instruments during the Credit Suisse rescue—a move that investors have challenged in court. This sensitivity has added complexity to the ongoing regulatory debate.

The recommendation from the more business-friendly upper house committee marks only the initial phase of a lengthy parliamentary process. The full upper house is scheduled to debate the reforms in mid-September, when lawmakers may accept, reject, or modify the proposal. Subsequently, the measures will be considered by the lower house. Neither the committee’s endorsement nor the eventual parliamentary decisions are final, leaving significant uncertainty over UBS’s future capital requirements.

The Swiss finance ministry declined to comment on the matter. UBS did not respond to requests for further statements. The outcome will be closely watched by investors and regulators as Switzerland balances strengthening its banking system with preserving the competitiveness of one of its largest financial institutions.
