UBS repurchases $7.93B in Credit Suisse senior notes in largest post-acquisition debt reduction

UBS just pulled off its biggest single move to shed the financial baggage it inherited when it swallowed Credit Suisse in 2023. The bank repurchased $7.93 billion in principal amount of legacy Credit Suisse senior notes through nine concurrent cash tender offers, settling on September 14.

The numbers behind the buyback

The tender offers launched on September 2 and concluded on September 10, with UBS initially setting a maximum purchase consideration that it later upsized to approximately $5.85 billion. Strong investor participation drove that increase, suggesting bondholders were eager to cash out of legacy Credit Suisse paper.

The repurchased notes spanned multiple currencies: US dollars, euros, and British pounds. Maturities stretched as far out as 2033, and some carried coupons as high as 9.016%.

This latest buyback follows a $7.7 billion tender UBS conducted in November 2025, bringing the cumulative total of retired Credit Suisse debt to roughly $15.6 billion. The result: UBS’s legacy Credit Suisse debt now sits at approximately $29 billion, down from the $90 billion starting point.

Why UBS is moving aggressively

UBS is actively managing its total loss-absorbing capacity, known as TLAC. By retiring old Credit Suisse notes and issuing new UBS instruments, the bank can reshape this buffer on its own terms rather than inheriting the credit profile of a failed rival.

The broader integration of Credit Suisse is reportedly on track to wrap up by the end of 2026, with cost efficiencies from the merger exceeding $12 billion.

UBS shares did dip roughly 2.8% around the time of the announcement, though that movement appeared to reflect broader market trends rather than investor dissatisfaction with the buyback itself.

What this means for the banking landscape

The Credit Suisse acquisition was engineered by Swiss regulators over a single weekend in March 2023 to prevent a Lehman-style contagion event. Going from $90 billion in inherited debt to $29 billion represents meaningful progress, and the pace is accelerating: the November 2025 tender retired $7.7 billion, while this latest round retired $7.93 billion.
