UBS Group AG, Switzerland’s largest bank, dramatically increased its exposure to Bitcoin through BlackRock’s spot exchange-traded fund during the first half of 2026, even as the underlying asset’s price declined sharply. A regulatory filing shows the Zurich-based lender held roughly 2.5 million shares of the iShares Bitcoin Trust (IBIT) valued at nearly $90 million as of June 30.

The position, disclosed in a Form 13F quarterly holdings report submitted to the U.S. Securities and Exchange Commission on Aug. 13, represents a roughly 355% increase in share count from approximately 549,000 shares at the end of 2025. By market value, the stake grew about 230% from roughly $27 million six months earlier.

The expansion is particularly notable because it occurred during a period of significant price weakness for the fund. IBIT’s market price fell approximately 33% during the six months through June 30, meaning the increase in reported value stemmed entirely from additional share purchases rather than price appreciation.

What the Filing Does and Doesn’t Reveal

Form 13F filings require institutional investment managers exercising discretion over at least $100 million in certain securities to report their holdings to the SEC each quarter. The reports capture positions as of the quarter-end date, meaning UBS could have altered its IBIT exposure between June 30 and the Aug. 13 filing date.

Crucially, the filing does not distinguish between shares owned by UBS itself and those held on behalf of clients. The document combines securities managed under the institution’s investment discretion and may include positions in client, advisory, wealth-management, or asset-management accounts. As a result, the disclosure should not be interpreted automatically as a direct $90 million purchase using the bank’s corporate capital.

Even at nearly $90 million, the holding remains small relative to UBS’s overall operations. In its second-quarter results published July 29, the bank reported a record $7.3 trillion in group invested assets, along with $2.8 billion in net profit for the quarter. Against those figures, the IBIT position represents a limited allocation rather than evidence that Bitcoin has become a major component of the bank’s investment strategy.

Institutional Access Through Regulated Vehicles

The move fits a broader pattern of traditional financial institutions using regulated, exchange-traded products to gain Bitcoin exposure. The SEC approved U.S. spot Bitcoin ETFs in January 2024, creating a pathway for banks, asset managers, advisers, and brokerage customers to access the asset through familiar market infrastructure.

UBS had previously allowed certain wealth-management clients with brokerage accounts to buy spot Bitcoin ETFs after their U.S. approval, while applying eligibility and risk controls to access. In January, the bank reportedly planned to give select high-net-worth and ultra-high-net-worth private banking clients in Switzerland access to cryptocurrency investments.

Beyond IBIT, UBS’s SEC filing shows investments in other Bitcoin-related ETFs, including premium income and alternative vehicles, bringing the bank’s total cryptocurrency ETF holdings to nearly $90 million. The bank also reported an investment of approximately $1.5 million in American Bitcoin Corp., a mining company associated with Eric Trump and Donald Trump Jr.

IBIT’s Market Position

IBIT remains the dominant U.S. spot Bitcoin fund despite weak first-half performance. BlackRock reported the fund had approximately $47.34 billion in net assets and 1.32 billion shares outstanding as of Aug. 12. UBS’s reported 2.5 million shares would account for about 0.19% of IBIT’s outstanding share count.

The fund attracted $183.4 million on July 30, accounting for 78.7% of the $233.1 million entering U.S. spot Bitcoin products that day. The daily inflow was the fund’s largest since July 6, when it received $209.4 million.

Fund data show IBIT returned negative 32.97% on a net asset value basis during the first half of 2026 and negative 45.62% over the 12 months through June 30. The fund’s 52-week net asset value range stood at $33.19 to $71.32 as of Aug. 12.

Broader Institutional Trends

UBS is not alone in adjusting its Bitcoin fund positions. A July filing showed Wells Fargo trimmed its IBIT stake while adding to some other Bitcoin funds and increasing its exposure to Ethereum and Solana investment products. The bank also opened an IBIT call position and increased its put exposure, demonstrating that institutions use the fund for hedging and trading as well as long-only Bitcoin exposure.

Regulated derivatives around IBIT have also expanded. In July, the SEC allowed NYSE Arca to quadruple its options limit from 250,000 to 1 million contracts after the exchange said trading activity justified a higher ceiling.

UBS must disclose its next quarter-end U.S. securities positions in a later 13F filing, which will show whether the reported IBIT share count was increased, maintained, or reduced as of Sept. 30.
