UBS reported second-quarter revenue of $12.3 billion, a 15% year-over-year increase, driven by its wealth management arm which posted $5.2 billion in inflows during the period. The bank announced a share buyback program of up to $2 billion through year-end, the first capital return since absorbing Credit Suisse fifteen months ago. The Zurich-based lender also confirmed integration expenses dropped to $1.1 billion for the quarter, down from $1.8 billion in Q1, signaling the final stretch of the largest emergency banking consolidation in European history.
The wealth management division generated $4.7 billion in revenue, beating consensus estimates by 9%, while net new assets climbed to $27 billion for the quarter. Americas wealth operations contributed $1.9 billion, marking the strongest quarterly performance in that geography since 2021. Investment banking revenue landed at $1.6 billion, flat sequentially but up 22% year-over-year, as dealmaking activity in Asia-Pacific accelerated. The bank's cost-to-income ratio improved to 73.2%, down from 79.8% a year earlier, as headcount reductions and technology platform consolidations began materializing in the expense base.
The buyback authorization matters because it signals UBS management believes the Credit Suisse integration risk is now quantifiable and contained. The bank has migrated 68% of Credit Suisse client accounts onto UBS platforms, ahead of its internal timeline, and expects full systems integration by Q1 2025. Credit Suisse-related legal provisions fell to $340 million this quarter from $890 million in Q4 2023, suggesting tail risks around litigation and regulatory settlements are declining faster than anticipated. The $2 billion buyback represents roughly 2.3% of outstanding shares at current prices, a modest but deliberate signal that capital allocation is shifting from defense to offense.
Allocators should watch three developments over the next ninety days. First, UBS will report September-end Assets under Management figures in mid-October, which will show whether wealth client retention held through the Northern Hemisphere summer, historically a period of heightened portfolio review. Second, the bank faces a Swiss regulatory review in November regarding capital requirements for the combined entity, where any increase above the Basel III minimums could pressure the buyback trajectory. Third, Credit Suisse's Asia private banking book, still being integrated, will report Q3 flows separately for the final time, offering a clean read on whether ultra-high-net-worth clients are staying or scattering to rivals like Julius Baer and Pictet.
The 73.2% cost-to-income ratio is the number that matters. It sits between the 68% UBS ran pre-acquisition and the 82% Credit Suisse carried into the merger. Every quarter it ticks lower, the market will reprice the equity higher, because the revenue synergies are proving durable while the cost cuts are arriving early.
