Summary
U.S. cryptocurrency ETF flows revealed a stark divergence on Friday, September 12, with ether funds capturing substantial institutional capital while bitcoin ETFs extended a losing streak. Bitcoin ETFs posted their fourth consecutive day of outflows, shedding $13.29 million as the asset's price remained stalled near $77,000. The week proved entirely negative for bitcoin funds, which accumulated $462.73 million in total outflows. BlackRock's IBIT, the largest bitcoin ETF, recorded a $19.23 million outflow on the session, though this was partially offset by inflows to Morgan Stanley's MSBT ($3.76 million) and VanEck's HODL ($2.18 million).
Ether ETFs moved decisively in the opposite direction, attracting $216.41 million across six funds on the same day and closing their fourth consecutive week with net inflows. BlackRock's ETHA dominated the inflows with $148.82 million, underscoring strong institutional appetite for ethereum exposure. Additional contributions came from Bitwise's ETHW ($29.09 million), BlackRock's ETHB ($18.32 million), Fidelity's FETH ($11.40 million), Grayscale's Ether Mini Trust ($5.09 million), and VanEck's ETHV ($3.71 million). The ether ETF complex's net assets climbed to $16.31 billion, reflecting gains of approximately $1 billion on the trading session alone.
The divergence highlights a significant rotation of institutional capital from bitcoin into ethereum, despite broader macro uncertainty. Bitcoin ETF trading value reached $2.60 billion on Friday, while ether ETF trading volume surged to $2.56 billion, indicating robust participation in the ethereum shift. Market participants identified Federal Reserve policy signals and inflation data as critical factors determining whether bitcoin can reclaim the $80,000 level, with institutional flows positioned as a key barometer heading into the following trading week. The sustained strength in ether inflows, even as bitcoin faces redemption pressure, suggests a tactical reallocation within institutional crypto allocations rather than broad-based sector weakness.
