Swiss lawmakers had a vote scheduled for Tuesday on new capital rules for UBS, the Swiss bank. It didn't happen.
The upper house's Economic Affairs and Taxation Committee put off the vote on Aug. 11, 2026, and a parliament spokesperson said the matter will come up again on Aug. 31. The delay keeps the government's plan in limbo and pushes back the first official signal on how lawmakers might change it.
That plan could force UBS to hold about $20 billion in extra highest-quality equity capital, the highest-quality cushion a bank can keep against losses. The rules were drafted following the collapse of Credit Suisse.
The finance ministry wants UBS to hold enough domestic equity to cover the full book value of its overseas operations, a measure the bank has fought since the idea surfaced in 2024.
A UBS representative declined to comment.
The real debate is about what should count as top-tier capital. Committee chairman Erich Ettlin, a centrist lawmaker, told reporters that lawmakers discussed letting UBS meet part of its capital needs with AT1 bonds instead of more expensive equity.
AT1 bonds, short for Additional Tier 1, are a type of debt that banks can write down or convert into stock when capital runs low. They cost banks less than raising equity, which is why UBS likes the idea.

Ettlin has a warning for anyone treating this as a simple fix. "The core question is, do AT1s work for this and if so, to what extent can they be used?" he said.
He also stressed that any changes have to pass an international test: "We want AT1s, which are accepted in an international context. Otherwise, they're useless."
Several proposals are on the table, the committee said, combining full capital backing with a partial option to use AT1 bonds. The bond terms would need adjusting so they help stabilize the bank early.
Investors who hold AT1 debt have their own worries. They fear more issuance would flood the market and that altered bond terms would make it harder for them to get paid.
UBS supporters, mostly from the center-right, back the proposal with extra safeguards built in. Those safeguards would bar coupon payments and shareholder payouts if UBS's capital ratio falls below a set threshold.
That is a direct response to problems that surfaced during Credit Suisse's collapse more than three years ago. The goal is to make sure AT1 bonds actually absorb losses in a crisis.
The committee says all members agree UBS should hold more capital. The disagreement is about how to balance public safety against the competitiveness of Switzerland's financial center.
The delay does not mean the plan is dead. The government's proposal is likely to be watered down rather than abandoned.
The stock barely moved on the news, losing just 0.6% by 2:30 p.m. in Zurich. That tells you the market did not see the delay as a shock.
But the bigger question is what happens to UBS's bonds. UBS ranks among the world's biggest issuers of AT1 bonds, so any change to how those instruments work would ripple through a market that already has reasons to be nervous.
Swiss financial authorities are expected to send the committee a report on the AT1 ideas under discussion. The whole process will likely stretch into next year, so there is time for the details to shift.
Banks that hold more capital are safer, but the extra cushion usually eats into returns for shareholders. For investors, the trade-off is simple: more safety usually means lower returns.
The coming weeks will be telling. If the committee leans toward accepting AT1 bonds as part of the solution, UBS may avoid the full $20 billion equity hit. If not, shareholders could feel the squeeze. Either way, the debate is far from settled, and the next hearing on Aug. 31 will offer the first real clue about which direction lawmakers are heading.
