Morgan Stanley launched the cheapest US spot Bitcoin ETF at 0.14%, undercutting BlackRock's IBIT by 11 basis points, but analysts say the market leader will not blink unless outflows accelerate or Vanguard enters the fray.
Morgan Stanley entered the spot Bitcoin ETF arena on April 8 with a clear message: we will compete on price. The Morgan Stanley Bitcoin Trust, trading under the ticker MSBT, carries an expense ratio of just 0.14%. That undercuts BlackRock's dominant iShares Bitcoin Trust (IBIT) by 11 basis points and edges past Grayscale's Bitcoin Mini Trust, which sits at 0.15%. Fidelity's Wise Origin Bitcoin Fund (FBTC) now looks comparatively expensive at 0.25%.
The debut was strong by any standard. MSBT pulled in roughly $30.6 million in net inflows on its first day and processed over 1.6 million shares. As BeInCrypto reported, Bloomberg senior ETF analyst Eric Balchunas ranked the launch among the top 1% of all ETF debuts and projected the fund could reach $5 billion in assets under management within its first year.
Yet BlackRock has no reason to panic. IBIT holds approximately $55 billion in assets, giving it a liquidity advantage that matters far more to institutional traders than a few basis points in fees. Tighter bid-ask spreads and a deeper options market make IBIT the default choice for large allocators who prioritize execution costs over headline expense ratios. Balchunas put it plainly: when you sit at the top of the hill with enormous liquidity, you set the price.
Fellow Bloomberg analyst James Seyffart reinforced that view, noting that matching IBIT's liquidity is not something MSBT can achieve in the near term. For institutions moving serious volume, the hidden costs of trading a less liquid fund can easily exceed any savings from a lower management fee.
MSBT's aggressive pricing is less a threat to BlackRock and more a problem for the middle tier. Smaller issuers lacking scale will face uncomfortable choices: absorb the cost of a fee cut to stay competitive, or accept a shrinking share of new inflows. In a market where every spot Bitcoin ETF holds the exact same underlying asset, fees become one of the few levers available to differentiate.
Morgan Stanley also brings a distribution advantage that most rivals simply cannot match. The bank's wealth management division fields roughly 16,000 financial advisors overseeing $9.3 trillion in client assets. Those advisors can now recommend an in-house product instead of routing clients to third-party funds. That built-in distribution network gives MSBT a structural edge that pure-play crypto issuers like Bitwise or Ark Invest cannot replicate, regardless of how low they push their fees.
What Would Force BlackRock's Hand
Balchunas identified only two realistic scenarios that could push BlackRock to lower IBIT's fees. The first is sustained outflows from IBIT toward cheaper competitors. A single strong debut from MSBT does not qualify, but a multi-quarter trend of assets migrating to lower-cost alternatives would force a reassessment. The second would be Vanguard entering the market at roughly 0.10%, though Balchunas assigned that outcome a probability of just 0.01%. Vanguard has historically avoided crypto exposure and has shown no public indication of changing that stance.
The broader spot Bitcoin ETF market has now surpassed $100 billion in cumulative assets since the segment launched in January 2024, according to MacroMicro data. However, the growth trajectory has not been smooth. The market endured four consecutive months of net outflows from November 2025 through February 2026 before March reversed the trend with $1.32 billion in fresh inflows.
Whether MSBT sustains its opening momentum will determine how seriously competitors treat its pricing signal. If Morgan Stanley's fund captures a meaningful share of new monthly flows while maintaining its fee advantage, smaller issuers will face increasing pressure to cut costs or accept irrelevance. BlackRock, meanwhile, will keep watching from the top, confident that liquidity and brand trust matter more than a price war it can afford to ignore.
