The $129.62 million net outflow on March 18 marked the first negative day for US Bitcoin ETFs since March 6, when they saw $348.83 million in outflows [3]. Fidelity’s Wise Origin Bitcoin Fund (FBTC) accounted for the largest portion of the recent outflows, shedding $103.84 million, equivalent to 1,460 BTC [3]. Grayscale’s Bitcoin Trust (GBTC) also recorded $18.82 million in outflows, or 264.24 BTC, deepening its cumulative net outflow position to $25.95 billion [3]. Bitwise’s Bitcoin ETF (BITB) saw $6.96 million in outflows [3].
The seven-day inflow streak, from March 9 to March 17, saw daily net inflows ranging from $53.87 million to $250.92 million [3]. During this period, cumulative total net inflows across all US Bitcoin ETFs reached $56.54 billion before the March 18 outflow reduced it to $56.41 billion [3]. Total net assets across these ETFs had climbed to $96.74 billion by March 17, up from $88.34 billion at the start of the streak [3].
The outflows occurred as Bitcoin's price briefly dipped below $65,000, with US stocks also falling amid renewed tensions between the US and Iran [2]. Market sentiment for Bitcoin weakened, with the Crypto Fear & Greed Index dropping 3 points to 28, remaining in "fear" territory [2].
Ethereum ETFs also experienced a shift, recording $55.51 million in total net outflows on March 18, ending a five-day streak of positive flows [3]. Fidelity’s Ethereum Fund (FETH) led these outflows with $37.11 million, or 16,950 ETH [3]. Grayscale’s Ethereum Trust (ETHE) shed $8.89 million, or 4,060 ETH [3]. Despite the single day of outflows, Ethereum spot ETFs had posted $174.15 million in weekly net inflows for the week ending March 17, their strongest weekly figure in the current run [3].
ETF fund flows are often used to observe institutional allocation preferences and assess whether capital inflows are driving trend formation, particularly when compared with derivatives market indicators [1]. Steady ETF inflows without significant expansion in derivatives market leverage can suggest a healthy market structure dominated by long-term capital [1].
The recent outflow marks a break in a period of significant institutional interest in Bitcoin ETFs, highlighting the sensitivity of these products to broader market conditions and geopolitical events.
