According to Bitfinex Alpha, Bitcoin broke below the key support level of $77,100 on September 15, closing at $75,702 with a daily decline of 3.2%, marking its third consecutive closing lower after breaking through the recent range bottom. On that day, US spot Bitcoin ETFs recorded a net outflow of $450.4 million, with Fidelity FBTC seeing an outflow of $214.8 million and BlackRock IBIT recording an outflow of $161.7 million, accounting for 84% of total outflows. This marks the 14th-largest single-day net outflow in 2026. The downturn was driven by multiple factors: the failure of the CLARITY Act to advance, the 10-year US Treasury yield rising to 5% (for the first time since 2023), accelerated selling by short-term holders (exchange inflows surged sharply from 19,400 BTC to 33,100 BTC, of which 23,200 BTC were acquired at a loss), and foreign demand dropping to a historic low during the 20-year US Treasury auction. From a technical standpoint, BTC has fallen below the market average value of $76,500 and Strategy's average holding price of $75,412, leaving the average holder currently underwater. If the downtrend continues, key support levels below are $73,500 (cost basis for 3-6 month holders) and $71,300 (realized price for short-term holders). A rebound requires reclaiming $77,100 backed by significant spot trading volume.
In a write-up by Wintermute OTC trader @Jjay_dm, BTC ETFs recorded a net outflow of $463 million for the week ending September 14, marking the first negative reading since June's lows. ARK and Grayscale alone accounted for combined outflows of $371 million, while BlackRock remained flat. As a result, BTC fell 4.4% for the week to close at $76,838, making it the worst-performing asset, while Ethereum dipped 1.5% and altcoins collectively gained 1.0%. On the macro front, the US August CPI came in at 0.4% month-on-month (core 0.3%), exceeding the expected 0.2%, while the PPI annual rate hit 5.4%, prompting Goldman Sachs to upgrade its September rate outlook from "hold steady" to "increase." The market has now priced in an 87% probability of a 25-basis-point hike on Wednesday. Meanwhile, ongoing escalation in Middle East tensions pushed Brent crude past $105/barrel, and the 10-year US Treasury yield reached a 20-year high. Wintermute stated that following the shift to negative ETF flows, it favors a neutral over a bullish market stance. Two key catalysts this week: ① On Tuesday, the US Senate will hold a procedural vote on the CLARITY Act (Crypto Market Structure Act), which requires 60 votes to pass; ② On Wednesday, the Fed will announce its interest rate decision. While the rate hike itself is already fully priced in, subsequent hawkish commentary (particularly any signals pointing to continued tightening into Q1 2027) could exert downward pressure on the crypto market.
