KoinlyticsUS spot Bitcoin and Ethereum ETFs took in roughly $1.1 billion in combined net inflows for the week ending August 7. Bitcoin funds accounted for close to $854 million of that. Ethereum funds added $244.9 million, their fifth consecutive positive week.
On Friday alone, Bitcoin ETFs recorded $101.7 million in net inflows, with BlackRock's IBIT taking $86.7 million and Fidelity's FBTC adding $41.0 million. Those two figures exceed the day's net, which means at least one other fund was net negative.
Why the Week Turned
The trigger was Friday's jobs report. July nonfarm payrolls fell 23,000 against a forecast of plus 80,000, wage growth slowed to 3.2% year over year, and September Federal Reserve hike odds dropped from 61% to 44%.
The transmission into ETF flow is direct and mechanical. Bitcoin pays nothing. Its entire competitive position against Treasuries is a function of what Treasuries pay. Every basis point removed from expected policy rates lowers the hurdle Bitcoin has to clear in an allocation model, and allocation models are what drive ETF flow.
This is why July was a drought. Rate expectations were moving the other way all month.
The Composition
- Bitcoin ETFs: roughly $854 million for the week, with no day of net outflows recorded in August
- Ethereum ETFs: $244.9 million, a fifth straight positive week
- August 7 alone: $101.7 million into Bitcoin funds, IBIT $86.7 million, FBTC $41.0 million
- Combined: approximately $1.1 billion
The Ethereum Reversal Is the Real Change
Ethereum funds had been leaking for most of the year. Five consecutive positive weeks and $244.9 million in a single week is a different regime, and the explanation is not that ether suddenly became attractive.
It is that the product changed. Staked Ethereum ETFs pass through roughly 2.8% to 3.5% annually, which converts ether from a non-yielding asset into a yielding one inside the same wrapper. That reframes the Treasury comparison entirely, because the competition is no longer zero against 4.5%, it is 3% against 4.5%.
Institutional filings have made this visible. Intesa Sanpaolo's Q2 disclosure cut its Bitcoin ETF position by 93.7% while nearly tripling its staked Ethereum holding. That is not a view on which chain wins. It is a treasury desk choosing the instrument that pays.
A billion dollars in a week reads as conviction. It is closer to arithmetic. The Fed moved a probability, and allocation models recalculated.
What $854 Million Buys
Not much price, as it turns out. Bitcoin went from roughly $64,259 to $65,200 across the week, a gain under 1.5% on nearly a billion dollars of net demand.
Two readings. The charitable one is that supply is being absorbed quietly and the price effect shows up later. The skeptical one is that ETF buying is being met by sellers of comparable size, which is what you would expect in a market where more than 200 treasury companies are trading below net asset value and losing the ability to accumulate.
Both are consistent with the data. What the data does rule out is the idea that a billion dollars of institutional demand automatically produces a rally.
What to Watch
- Whether the streak survives the July CPI print due August 12, the next event with the power to move rate expectations
- Combined staked plus spot Ethereum ETF flow as a single figure rather than the spot number alone
- Daily Bitcoin ETF absorption against roughly 450 BTC of new issuance per day
- Whether IBIT's share of net flow keeps widening, which concentrates the complex in one issuer
- Whether the price response to inflow improves, which would signal the sell side thinning out
A billion dollar week is a useful reminder that flow and price are different variables, and that a portfolio built on one while watching the other will keep producing surprises. If your positions moved less than the headline suggested they should, that gap is information rather than an error.
