Bitcoin ETF inflows resume, led by BlackRock ahead of Fed meeting

US spot Bitcoin exchange‑traded funds (ETFs) posted a net inflow of $159.9 million on Sept. 14, ending four days of withdrawals that had taken $462.7 million out of the market.

Key drivers of the rebound

The inflow was heavily concentrated in two products:

• iShares Bitcoin Trust (IBIT) – $134.3 million
• Wise Origin Bitcoin Fund (FBTC) – $53.3 million

Together they accounted for $187.6 million, more than the market’s net total, because outflows elsewhere offset part of the demand.

Other fund activity

Other ETFs showed mixed results:

• ARK 21Shares Bitcoin ETF (ARKB) – $42 million outflow
• Franklin Templeton’s EZBC – $4.6 million inflow
• Morgan Stanley’s MSBT – $9.7 million inflow
• Most remaining funds reported no net movement

Long‑term flow trends

Blockchain data indicate that IBIT added roughly $1.08 billion of Bitcoin over the past 20 days, with positive flows on seven sessions. In contrast, Grayscale’s GBTC reduced its Bitcoin holdings by about $254.7 million during the same period.

Implications ahead of the Fed decision

The inflow arrives just before the Federal Reserve’s Sept. 15‑16 policy meeting, a key test for Bitcoin ETF demand. A shift in rates or risk appetite could either sustain the rebound or trigger further redemptions, especially given the concentration of activity in BlackRock and Fidelity.

Outlook

If risk appetite improves after the Fed meeting, broader ETF demand could expand beyond IBIT and FBTC. Conversely, renewed redemptions would suggest the September 14 inflow was a temporary pause rather than a durable recovery.
