Switzerland’s largest bank, UBS, increased the reported value of its position in BlackRock’s spot Bitcoin exchange-traded fund by approximately 230% during the first half of 2026, taking the holding to nearly $90 million. A Form 13F filed with the U.S. Securities and Exchange Commission on August 13 showed UBS reporting approximately 2.5 million shares of the iShares Bitcoin Trust, or IBIT, as of June 30.
That compares with roughly 549,000 shares valued at about $27 million at the end of 2025. The number of shares therefore increased by approximately 355%, while the reported dollar value climbed about 230%. The distinction matters because IBIT itself declined substantially during the period. BlackRock data show a market-price return of approximately negative 33% during the six months through June 30, meaning UBS’s higher reported exposure primarily reflected an increase in shares rather than appreciation in the ETF.
UBS Significantly Expands Its IBIT Position
The filing represents a substantial expansion from UBS’s earliest reported exposure to U.S. spot Bitcoin ETFs. The bank initially disclosed only several thousand IBIT shares in 2024, shortly after the SEC approved spot Bitcoin exchange-traded products in January of that year. Its latest position illustrates how regulated Bitcoin exposure has increasingly moved into conventional institutional portfolios. However, the $90 million figure should be viewed in context.
UBS reported a record $7.3 trillion in group invested assets in its second-quarter results, alongside $2.8 billion in quarterly net profit and $5.8 billion for the first half of 2026. A $90 million IBIT position is consequently tiny relative to the overall scale of the bank’s wealth and asset-management operations. The filing also does not prove that UBS itself made a proprietary $90 million Bitcoin bet. Form 13F reports securities over which institutional investment managers exercise investment discretion and can include positions associated with client, advisory and asset-management accounts.
Bitcoin Moves Further Into Traditional Wealth Management
The increase nevertheless arrives as UBS expands its broader digital-asset strategy. The bank has been evaluating cryptocurrency trading services for selected private-banking customers, potentially allowing wealthy clients to trade Bitcoin and Ether through traditional banking infrastructure. IBIT provides another route. Rather than requiring investors to directly purchase Bitcoin, manage private keys or arrange cryptocurrency custody, the ETF provides exposure through a conventional exchange-listed security.
BlackRock’s fund has become the dominant U.S. spot Bitcoin ETF since its January 2024 launch, attracting institutional investors ranging from hedge funds and investment advisers to banks and asset managers. UBS’s latest filing therefore represents more than a percentage increase in a relatively small portfolio position. It demonstrates how Bitcoin exposure is increasingly being absorbed into the same regulatory reporting and investment infrastructure used for conventional securities. For a bank overseeing $7.3 trillion in invested assets, $90 million remains immaterial. But the trajectory is notable: UBS reported roughly 549,000 IBIT shares at the end of 2025 and approximately 2.5 million only six months later.
The next quarterly filing will show whether that expansion was temporary portfolio positioning or part of a longer-term increase in demand for regulated Bitcoin exposure across UBS-managed accounts.
