Bitcoin spot ETFs flip to ~$84–$85M outflows as ether ETFs add ~$70M
The split hit as the U.S. 10-year yield held near 4.60%, a seven-week high that has pressured risk appetite.
U.S. spot bitcoin ETFs returned to net outflows on Wednesday at roughly $84–$85 million, snapping a three-session inflow run that totaled about $509 million. Spot ether ETFs moved the other way, adding about $70 million for a fifth straight inflow day as the U.S. 10-year yield hovered near 4.60%.
Key Takeaways
- U.S. spot bitcoin ETFs posted roughly $84–$85 million of net outflows on Wednesday, ending a three-session inflow streak totaling about $509 million.
- Spot ether ETFs added about $70 million on the day, extending inflows to five straight sessions, with Fidelity’s FETH contributing roughly $69 million.
- Bitcoin redemptions were spread across major products including IBIT (~-$59M), GBTC (~-$64M), and FBTC (~-$15M), partly offset by Grayscale’s mini BTC fund at nearly +$53M.
- After the session’s flows, aggregate assets sat near $75 billion for bitcoin ETFs and about $9 billion for ether ETFs.
ETF Flows Diverge: Bitcoin Back to Outflows, Ether Extends Its Streak
Wednesday’s U.S. spot ETF tape split cleanly by asset. Bitcoin ETFs swung back to net outflows of about $84–$85 million, reversing a three-session inflow run that had totaled roughly $509 million, per SoSoValue.
Ether ETFs kept leaning the other way. The group pulled in about $70 million, extending inflows to a fifth straight session. In a market that has been trading headline-to-headline, that divergence is the kind of near-term positioning signal flow-watchers latch onto, especially with both majors under pressure on the day.
Under the Hood: Broad Bitcoin Selling vs. Concentrated Ether Buying
The bitcoin outflow did not read like a single-product rotation. BlackRock’s IBIT was about -$59 million, Grayscale’s GBTC nearly -$64 million, and Fidelity’s FBTC about -$15 million. Grayscale’s mini BTC fund was the notable offset at nearly +$53 million, but it was not enough to flip the complex back to green.
Ether’s inflow streak continued, but the composition matters. Fidelity’s FETH accounted for roughly $69 million of the day’s ~$70 million total, while VanEck’s ETHV added just over $1 million and every other ether fund was flat. That concentration keeps the streak alive, but it also means “broad-based” ETH demand across issuers is not yet showing up in the prints.
After the day’s creations and redemptions, total assets across U.S. spot bitcoin ETFs were about $75 billion. Ether ETF assets were about $9 billion.
Rates Pressure the Tape: 10-Year Yield Near 4.60% as Crypto Slips
The macro overlay stayed hostile. The U.S. 10-year Treasury yield steadied near 4.60%, a seven-week high reached Wednesday, and was up by over 10 basis points month-to-date. The setup fits a familiar pattern: firmer yields tighten financial conditions at the margin and can coincide with softer crypto prices even when ETF flows are mixed.
Price action matched the risk-off tone. Bitcoin traded near $62,300 and ether near $1,740, both down about 3% at the time referenced. Even with that downtape, ether was described as outperforming bitcoin over the past two weeks, helped by the “Lean Ethereum roadmap” narrative and the return of consistent ETF inflows.
Next Flow Prints and the 4.60% Yield Level Traders Are Watching
The next 1–3 sessions of ETF prints matter more than any single day’s reversal. For bitcoin, the immediate question is whether flows snap back to net inflows or whether Wednesday marks the start of a renewed outflow run.
For ether, the real test is whether the complex can post a sixth straight inflow day and whether demand broadens beyond Fidelity’s FETH. A streak driven by one vehicle can persist, but it is more fragile if that one source pauses.
Rates remain the other lever. The 4.60% area on the U.S. 10-year is the level to watch for a hold and pullback versus a break higher, given the framing of yields as a headwind for risk assets. Participation signals also sit in the aggregate AUM trend, with bitcoin ETFs around $75B and ether ETFs around $9B after Wednesday’s flows.
Reading the BTC/ETH Flow Split as a Positioning Signal, Not a Verdict
I treat this tape as a positioning tell, not a final judgment on either asset. Bitcoin flows cooled fast after a three-day +$509M run, and the outflows were broad enough across IBIT, GBTC, and FBTC to look like de-risking rather than a neat reallocation story.
The threshold that matters is whether ether can keep printing inflows once FETH is not doing all the work, and whether bitcoin can reclaim consistent inflows while the 10-year yield is pinned near 4.60%. If those two conditions hold, the setup starts to look structural rather than narrative-driven, and that is when the flow split becomes tradable information instead of just a headline.
