Morgan Stanley filed an amended S-1 with the SEC on Friday for its proposed spot bitcoin ETF (ticker: MSBT), pricing the fund at 14 basis points — the lowest expense ratio of any spot bitcoin product currently on the market.

The Fee War

Grayscale's Bitcoin Mini Trust currently holds the low-cost title at 15 basis points. BlackRock's iShares Bitcoin Trust (IBIT), the largest spot bitcoin ETF by assets, charges 25 basis points. By pricing MSBT at 14bps, Morgan Stanley undercuts both, setting up what could be a new round of fee compression across the category.

In the ETF market, cost is often the decisive factor when products track identical assets. Advisors can move client money between funds in a single trade, keeping bitcoin exposure while lowering annual costs. That dynamic has already punished Grayscale's flagship GBTC, which held $29 billion at launch in January 2024 and now holds around $10 billion.

Scale Matters

Morgan Stanley's wealth management arm oversees several trillion dollars in client assets with one of the largest adviser networks in the U.S. Even a modest bitcoin allocation across that base could redirect billions in flows away from existing funds.

The NYSE has issued a listing notice for MSBT, signaling the exchange is ready to list the fund pending SEC approval. If approved, MSBT would be the first spot bitcoin ETF issued directly by a major U.S. bank.

The move signals that institutional interest in bitcoin exposure remains strong despite recent price weakness, and that the ETF fee floor has not yet been found.
