Swiss Parliament Advances Compromise on UBS Capital Regulation
nashnova research
A Swiss upper-house committee is set to cut UBS's overseas subsidiary capital coverage from the government's 100% to 50%, potentially slashing a roughly $20 billion extra-capital demand — but the lower house is expected to push back harder, and final rules won't land before late 2026 at the earliest.
Why does the government want $20 billion more from UBS?
After UBS's emergency takeover of Credit Suisse in 2023, Switzerland demanded roughly $20 billion in additional Common Equity Tier 1 capital — CET1, the hardest, most expensive form of bank capital.
This means → regulators see UBS's "too big to fail" risk as sharply higher post-merger and want it backed by the strongest buffer available.
UBS argues the requirement is excessive and would weaken its competitiveness against global peers.
What is the upper-house committee's compromise?
The key concession: let UBS back its foreign subsidiaries with 50% CET1, not the government's 100%.
In plain terms = instead of covering every dollar of overseas risk with the most expensive capital, UBS would only need to cover half.
The gap can be filled with Additional Tier 1 capital (AT1) — a hybrid instrument sitting between equity and ordinary bonds — which is cheaper for the bank to issue.
Alternative proposals at 75% and 80% are also still on the table.
Is plugging the gap with AT1 safe enough?
The committee is still debating safeguards to make AT1 debt more resilient.
This reflects a core tension: AT1 is cheaper, but in the 2023 Credit Suisse crisis AT1 bonds were written down to zero — lawmakers need to ensure "bargain capital" won't evaporate again in the next storm.
What is the legislative timeline from here?
The upper-house committee is expected to decide on August 31; the draft bill goes to the full upper house in September.
It then moves to the lower-house committee and plenary — where the stance toward UBS is expected to be significantly tougher.
This means → even if the upper-house version passes, the lower house will likely tighten it. Final rules arrive no earlier than late 2026, with the process likely stretching into 2027.
