US spot Bitcoin ETFs saw a sharp reversal in mid-September, shedding about $450 million in a single session on September 15 to mark their worst day since June. Fidelity's FBTC and BlackRock's IBIT recorded the largest withdrawals during the downturn, which coincided with declining Bitcoin prices, macroeconomic pressures, a Federal Reserve rate hike, and regulatory uncertainty surrounding the Senate CLARITY Act vote.

The negative momentum proved short-lived as demand returned to spot funds. By September 18, inflows reached roughly $433 million, nearly matching the earlier outflow and allowing the full week to end close to neutral. While spot Bitcoin ETFs managed a strong recovery, spot Ether ETFs finished the week with persistent net redemptions. [1]
