Morgan Stanley's spot bitcoin exchange-traded fund (ETF) MSBT attracted $194 million in its first month, posting no net outflows on any day.

On May 10, blockchain media outlet The Block Crypto reported that no competing spot bitcoin ETF sustained that pattern over the same period.

On its first day of trading on April 8, MSBT logged $30.6 million of net inflows and about $34 million in trading volume. Amy Oldenburg (에이미 올든버그), head of digital asset strategy at Morgan Stanley, called it the strongest ETF debut in the bank's history. Bloomberg ETF analyst Eric Balchunas also viewed MSBT's early performance as in the top 1 percent among ETF launches.

Inflows later cooled somewhat. In the first 2 weeks after listing, daily net inflows stayed in the high $10 million range, but later fell to single-digit millions. Net inflows never turned negative. According to Sosovalue, the broader spot bitcoin ETF market posted net inflows of $663.9 million on April 17, then showed volatility with net outflows of $277.5 million and $145.7 million on May 7 and May 8, respectively.

MSBT posted net inflows of $5.7 million on May 7. BlackRock's IBIT recorded net outflows of $27.2 million, Fidelity's FBTC had net outflows of $97.6 million, and ARKB posted net outflows of $26.6 million. MSBT traded at a 0.24 percent premium to net asset value, higher than IBIT's 0.18 percent and FBTC's 0.13 percent. The market reads this as a sign demand was stronger than the supply of creation units.

The pace of inflows was also fast. MSBT exceeded cumulative net inflows of $103 million just 6 trading days after listing. That surpassed WisdomTree's BTCW, which has traded since January 2024 and had cumulative net inflows of $86 million.

Fee competitiveness is cited as a factor. MSBT's annual management fee is 0.14 percent, the lowest among spot bitcoin ETFs. Grayscale Bitcoin Mini Trust charges 0.15 percent, Bitwise's BITB 0.20 percent, ARKB 0.21 percent, and IBIT and FBTC 0.25 percent each. The existing Grayscale GBTC charges 1.50 percent.

Even so, low fees alone are hard to cite as the sole explanation. The fee gap with IBIT is 0.11 percent, which may not be large for retail investors, but for $1 billion of institutional money it becomes a $1.1 million annual difference. Grayscale Bitcoin Mini Trust, which also highlights similar fees, recorded net outflows on more than 1 day over the same period, and its average daily inflows were smaller than MSBT's.

The nature of the initial money also stands out. Most of the first-month inflows came from self-directed clients rather than advisory channels. Morgan Stanley has about 16,000 financial advisers and more than $9.3 trillion in client assets, but MSBT was not offered on the bank's advisory wealth-management platform during the first few weeks after launch.

Morgan Stanley has about 16,000 financial advisers and more than $9.3 trillion in client assets. If its advisory channel fully opens, MSBT would gain an in-house distribution network that other spot bitcoin ETF issuers would find hard to secure. The company is also running a pilot of E-Trade spot crypto trading services starting with bitcoin, ether and solana. Fees for the service are 0.50 percent.

Market conditions also turned supportive. Thirteen spot bitcoin ETFs posted net inflows for 6 straight weeks through May 8, attracting more than $3 billion. It was the longest weekly streak of net inflows since last summer. Total net assets stood at $106.6 billion, about 6.67 percent of bitcoin's market capitalisation, and cumulative net inflows since the January 2024 launch reached $59.3 billion.

MSBT's first-month results place more weight on the stability of flows than on the absolute amount of inflows. With its presence confirmed by low fees and early self-directed demand alone, whether advisory channels are opened is left as a variable that will determine the pace of the product's expansion.
