Overnight, BTC fell rapidly from above $81,300, once dropping below $78,000. In the Asian session it was around $77,700, with a 24-hour decline of more than 3%. This time it is neither an on-chain incident nor a regulatory crackdown; rather, the market is repricing U.S. dollar interest rates. A hawkish speech by Federal Reserve Chair Warsh turned the once low-probability risk of “continued rate hikes in September” into a near coin-flip reality—about a 50/50 chance.
At Jackson Hole, Warsh clearly stated that the Fed should focus mainly on prices. His cited data were: U.S. PCE year-over-year is still 3.7%, and the annualized rate over the past six months is 4.1%, while the unemployment rate remains at 4.1% and the labor market is still stable. In other words, employment has not forced the Fed to ease, but inflation has provided a reason to keep tightening. Interest-rate futures then pushed the probability of a September hike from roughly 40% before the remarks to about 60%. The yield on two-year U.S. Treasuries rose to around 4.35%. The dollar strengthened, putting simultaneous pressure on BTC, tech stocks, and gold.
Why is BTC reacting so directly? Over the past two weeks, it rebounded from around $640,000 to $810,000. Behind it are two lines of funding logic: first, the U.S. Department of the Treasury has expanded its long-term Treasury buyback program, triggering discussions about dollar purchasing power and debt monetization; second, spot ETFs have been continuously attracting net inflows. Warsh emphasized that near-term interest rates are still the main policy tool, and he refused to give the market clear forward guidance—essentially putting the brakes on “trading in advance” for rate cuts or lower yields. Once real-rate expectations rise, valuations of high-volatility assets are compressed first.
ETF support also saw its first warning sign, but it’s still too early to conclude that institutions are撤退. Farside data shows that as of August 27, BTC spot ETFs posted net inflows for nine consecutive trading days, totaling about $3.04 billion. As of August 28, the net outflow disclosed for all projects combined was about $155.3 million, ending the streak of inflows with high likelihood. However, multiple funds such as IBIT and FBTC still show as not updated, so this figure is temporary and should not be taken as the final result. What really matters is whether the flow turns negative again continuously next week—not a single day’s data.
The bulls still have two layers of buffers: the earlier ETF inflow scale was far larger than the latest temporarily estimated outflow, and BTC has not fallen back below the start range of this round directly due to the remarks. The bears’ edge lies in the fact that there was already clear supply pressure in the $80,000–$83,000 zone. After the price surge failed, it then ran into weakening across three fronts— the dollar, short-end yields, and ETFs. With relatively thin weekend liquidity, stop-loss and leverage liquidations are easier to amplify.
Today, focus on three things: first, can BTC reclaim $78,000 and challenge $80,000 again; second, if there’s a rebound over the weekend, can trading activity and spot buying recover in sync; third, next week’s U.S. employment and inflation data—can it again push down the probability of a September rate hike. If $77,000 continues to be breached, be alert to a pullback toward around $75,000; if it quickly reclaims $80,000, it’s more likely to be a macro leverage washout.
The conclusion is: ETFs have not been proven to have failed, but the macro environment has shifted from tailwind to headwind. Don’t chase shorts based only on single-day outflows, and don’t treat the prior streak of inflows as permanent support. The above is for market analysis only and does not constitute investment advice; weekend volatility may increase, so control leverage and position size.
