Global investment bank Morgan Stanley has launched its bitcoin spot exchange-traded fund (ETF) MSBT with a total expense ratio of 0.14 percent, the lowest fee in the U.S. market. On April 9, blockchain media outlet BeInCrypto reported the product is 11 basis points lower than BlackRock's iShares Bitcoin Trust (IBIT).

The new ETF, the Morgan Stanley Bitcoin Trust (MSBT), listed on April 8. Net inflows on the first day were about $30.6 million, and the number of shares traded topped 1.6 million. Bloomberg ETF senior analyst Eric Balchunas rated the start as in the top 1 percent among all cases. He also saw MSBT reaching $5 billion in assets under management in its first year.

Market attention is focused on whether fee cuts will spread to BlackRock. Balchunas, however, saw a low chance BlackRock would respond immediately. He said of IBIT, "It has tremendous liquidity, and as it sits at the top of the market it also has pricing power." IBIT currently holds about $55 billion in assets, the largest among bitcoin spot ETFs.

The liquidity gap is cited as an important variable in attracting institutional money. IBIT has secured low trading costs and ample options liquidity. Those are factors institutional investors weigh when choosing a fund. Another Bloomberg analyst, James Seyffart, also saw it as difficult for MSBT to compete with IBIT on liquidity in the short term.

That does not mean there is no fee pressure at all. Balchunas warned MSBT's aggressive pricing could trigger fee cuts by other asset managers. Bitcoin spot ETFs all hold the same underlying asset, leaving limited room for differentiation. In that structure, fees become a core competitive tool.

MSBT's fee is in fact 1 basis point lower than Grayscale's Bitcoin Mini Trust (BTC) at 0.15 percent, and also lower than Fidelity's Wise Origin Bitcoin Fund (FBTC) at 0.25 percent. That means smaller managers could face more direct pressure to defend market share.

Morgan Stanley's distribution channels are also a variable. The firm's wealth management division has about 15,000 to 16,000 financial advisers in the United States, and client assets they manage total $9.3 trillion. Balchunas said, "I didn't expect it," as he pointed to Morgan Stanley's advisory network. Those advisers could in future recommend the firm's own ETF ahead of external products.

Some observers say the possibility that BlackRock revisits its fee policy depends on two conditions. The first is MSBT maintaining early inflows and drawing new money at a meaningful level. The second is rival managers treating that pricing signal as a real threat. The key, ultimately, is whether MSBT can go beyond being simply a low-cost product and change money flows.

The market environment is also a variable. Cumulative assets in the U.S. bitcoin spot ETF market have exceeded $100 billion since the products launched in January 2024. But in 2026 the pace slowed, with net outflows continuing for four consecutive months from November 2025 through February 2026. In March, the trend reversed with net inflows of $1.32 billion.

MSBT's ability to keep absorbing the post-March recovery in inflows, rather than ending its first-day success as a one-off, is expected to determine the intensity of future fee competition. Even if BlackRock does not move right away, the likelihood has increased that other managers will face pressure to cut prices first.
