Institutional demand for spot Bitcoin exchange-traded funds rose sharply this week, with total inflows exceeding $2.3 billion across all U.S. issuers. The uptick came just days before the U.S. Federal Reserve’s scheduled September FOMC decision, which markets expect to include a 25 basis-point cut.

Why are institutions favoring spot Bitcoin ETFs now?

Institutions are favoring spot Bitcoin ETFs to gain regulated, custody-backed exposure without direct coin custody. Lower expected interest rates reduce the opportunity cost of holding risk assets, prompting reallocations into digital-asset ETFs for portfolio diversification and potential upside.

What do the data and surveys show?

Market data show a surge in daily flows and trading volumes for leading ETFs. Ecoinometrics and public fund flow trackers reported the weekly $2.3B total and the $642M single-day peak. A Reuters survey of economists indicated 105 of 107 respondents expect a 25 basis-point Fed cut on September 17, which is consistent with the market’s rate-cut pricing fueling ETF allocations.

How do Bitcoin ETF flows compare to Gold ETFs?

Gold ETFs have outperformed year-to-date, with reported gains near 40% in the first eight months of 2025, and steady inflows. Bitcoin ETF flows have accelerated recently but remain behind Gold in cumulative performance. This week’s inflows suggest a potential catch-up dynamic if momentum continues.

How did fund performance and trading activity reflect investor interest?

Shares of top Bitcoin ETFs rose more than four percent over the week, mirroring inflow strength. IBIT’s $3.2 billion daily trading volume on September 12 reinforced its liquidity profile. BlackRock has also begun exploratory tokenization initiatives for IBIT following strong market uptake (reported as plain text sources: Ecoinometrics, Reuters).
