UBS, Switzerland's largest bank and one of the world's biggest wealth managers, has increased its position in Bitcoin through additional purchases of shares in BlackRock's iShares Bitcoin Trust (IBIT), according to a regulatory filing with the U.S. Securities and Exchange Commission.

The filing reveals that UBS now holds approximately 2.5 million shares in IBIT, bringing the total value of that position to over $83 million. The bank has been gradually expanding its exposure to the world's largest cryptocurrency by market capitalization since BlackRock's fund received regulatory approval in January 2024, ending a years-long SEC blockade on spot Bitcoin ETFs.

The SEC filing is the latest indicator that traditional financial institutions continue to seek exposure to Bitcoin through regulated investment vehicles. Exchange-traded funds such as IBIT enable investors to gain exposure to Bitcoin without the need to directly hold or store the cryptocurrency, making the asset class accessible within conventional custody and compliance frameworks.

Following the SEC's approval of multiple Bitcoin ETFs in January 2024, major financial institutions have been able to access the asset class through shares of funds that trade on conventional stock exchanges. BlackRock, the world's largest asset manager with over $10 trillion in assets, launched IBIT, which has emerged as the most successful cryptocurrency ETF by inflows, currently holding $47.3 billion in assets under management.

Pension funds and U.S. state governments have also acquired Bitcoin exposure through these ETFs, alongside more conventional holdings such as technology stocks and other U.S. equities, signaling a broadening of institutional adoption beyond hedge funds and crypto-native firms.

UBS's Bitcoin investments extend beyond IBIT. The filing indicates that the bank holds positions in other premium income and Bitcoin-related ETFs, bringing its total cryptocurrency ETF holdings to approximately $90 million. The bank, which significantly expanded its global wealth management footprint following its emergency acquisition of Credit Suisse in 2023, has been steadily building out its digital asset capabilities.

Additionally, UBS has disclosed a position in American Bitcoin Corp., a Bitcoin mining company backed by U.S. President Donald Trump's sons, Eric Trump and Donald Trump Jr. That holding is valued at just under $1.5 million.

Earlier this year, it was reported that UBS was planning to offer Bitcoin trading services to a select group of private wealth clients in Switzerland, joining other European private banks that have moved to accommodate growing client demand for cryptocurrency exposure.
