Bitcoin slid from around $79,500 to below $77,000 in the hours after Fed Chair Kevin Warsh's hawkish keynote at the Jackson Hole Economic Policy Symposium on Aug. 28. Warsh warned that inflation remains a bigger concern than the labor market and declined to rule out a rate hike, sending traders to price in higher odds of a September move. The drop came even as US spot Bitcoin ETFs recorded $924 million in net inflows for the week through Aug. 28, a sign that macro pressure is outweighing fund demand.
Warsh's inflation warning
Speaking at the annual symposium, Warsh made clear the Fed's fight against price pressures isn't over. He didn't commit to a specific path, but his refusal to take a September hike off the table was enough to shift rate expectations. The market responded quickly, and Bitcoin's slide accelerated as the speech wrapped. For a market that had been hoping for a dovish pivot, the message was blunt. Traders responded by pricing in higher odds of a rate hike at the September meeting, a sharp reversal from the easing bets that had been building through the summer.
ETF money keeps coming
The price action didn't stop money from moving into spot funds. BlackRock's iShares Bitcoin Trust led the way with $938 million in net inflows during the Aug. 24-28 stretch, and spot Ether ETFs added $824 million, with BlackRock's ETHA fund extending its inflow streak to 10 straight trading days. But the run hit a wall on Aug. 28, when Bitcoin ETFs posted a $201.81 million net outflow, ending a nine-day streak. August still stands as 2026's strongest month for Bitcoin ETFs, with more than $3 billion in net inflows. The disconnect is hard to miss: institutional demand is strong, but it hasn't been enough to push the price through resistance. The outflow on Aug. 28 came on the same day as Warsh's speech, suggesting some traders took profits into the hawkish news.
The $83,000 wall
CryptoQuant points to Bitcoin's 365-day moving average near $83,000 as a key bull market confirmation level. So far, BTC has repeatedly failed to close above it. That's the technical backdrop that's kept the price rangebound even as money pours into funds. Each attempt to break higher has been met with selling, and Warsh's comments only added to the pressure. The moving average has acted as a ceiling for weeks, and until Bitcoin can close above it, the rally lacks confirmation.
The next test comes at the Fed's September meeting, where Warsh's stance will be put into action. Until then, Bitcoin's inability to clear the $83,000 moving average leaves the bull case on hold.
