Swiss mega-bank UBS ramps up its Bitcoin exposure with a massive 24-fold surge in ETF call options
SkimNews Take
UBS's 24x call surge against only 12% growth in direct holdings reveals a leveraged bullish bet achieved with minimal capital, while the 53% drop in put options strips away the hedging cushion that would normally temper such positioning.

- UBS boosted its quarterly call option exposure to BlackRock's IBIT by over 24-fold, reaching 1.95 million underlying shares as of June 30, up from 80,000 three months earlier.
- UBS direct IBIT holdings rose 12% to 407,890 shares (worth ~$13.6 million), up from 364,371 shares at the end of Q1.
- UBS put option exposure dropped roughly 53% to 143,300 underlying shares, down from 303,300 at the end of March, reducing the bank's downside-hedging position.
- UBS current direct IBIT position of 407,890 shares remains below the 548,614 shares it reported at the end of 2025, per its fourth-quarter filing.
- UBS (~AUM $7 trillion) began preparing earlier this year to offer select Swiss private banking clients access to bitcoin and ether trading, though the filing does not confirm whether that initiative drove the options increase.
- BlackRock's IBIT filing omits strike prices and expirations, leaving UBS's net directional exposure unclear and leaving open whether the move reflects client initiatives, dealer hedging, market-making, or proprietary exposure.
- Cross-coverage from CoinDesk and The Block shows institutional Bitcoin ETF positioning diverging in Q2: Paul Tudor Jones' firm increased its IBIT stake after a year of selling, while Harvard left its position unchanged after a 43% prior-quarter cut.
Why it matters: UBS's call options now represent 1.95 million IBIT shares against just 407,890 in direct holdings — roughly 4.8x more synthetic upside than outright exposure — while put options fell 53%, signaling a sharp net bullish tilt even as direct shares remain below end-of-2025 levels. With $7 trillion in AUM, UBS is the largest bank yet to disclose this kind of leveraged Bitcoin ETF bet, and the optionality skew matters more than the headline holdings figure for where the bank actually sits on BTC direction.
