US-listed spot Bitcoin exchange-traded funds (ETFs) experienced a significant influx of capital on April 17, marking the largest single-day inflow since January. This surge, amounting to approximately $664 million, was fueled by the reopening of the crucial Strait of Hormuz for commercial shipping, following a ceasefire announcement by Iran’s foreign minister. US President Donald Trump later confirmed this development, which alleviated concerns surrounding potential disruptions in global energy supply and spurred a broader market rotation towards risk assets.
Among the ETFs, BlackRock’s iShares Bitcoin Trust (IBIT) topped the list, attracting an impressive $284 million. Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed closely with $163.4 million, while the ARK 21Shares Bitcoin ETF (ARKB) saw an inflow of $117.9 million. Additionally, Morgan Stanley’s newly launched MSBT fund captured $16.6 million, indicating early interest from investors in this bespoke offering.
Despite the robust inflow figures, market analysts urged caution regarding the sustainability of Bitcoin’s current rally. Ecoinometrics, a digital asset analytics firm, pointed out that while recent inflows demonstrate active market participation, they lack the momentum generally associated with a significant breakout. The firm described the market’s present condition as one of “participation without urgency,” noting that the sector continues to experience periodic outflows alongside inflows.
Ecoinometrics emphasized the inconsistency in daily data, mentioning that large, single-day inflows, which typically indicate strong demand, have yet to materialize. Without substantial and steady capital injections, analysts warned that any attempts by Bitcoin to maintain a bullish trajectory could be precarious.
The notable influx on April 17 also contributed to the most substantial weekly performance for Bitcoin ETFs since January. Over a five-day period, total net inflows reached $996 million, sitting just shy of the $1.4 billion recorded in early January. This spike effectively reversed an atypical week that began with a $291 million outflow on Monday. However, positive sentiment returned with subsequent gains of $411.5 million on Tuesday, $186 million on Wednesday, and a smaller $26 million on Thursday.
This marked the third consecutive week of inflows for Bitcoin ETFs, with the total amount of fresh capital reaching approximately $1.7 billion over this period. As it stands, the total net assets held by spot Bitcoin ETFs exceed $101 billion, contributing to cumulative net inflows of $57 billion since their inception. Analysts and investors alike continue to monitor market dynamics closely, as the landscape for Bitcoin and its associated financial products evolves.
