Weakness in U.S. stocks could weigh on Bitcoin demand, with daily net inflows into spot Bitcoin ETFs reaching a one-month high.

Bitcoin fell around 1% over the past 24 hours, while Ethereum dropped 1.4%. Weak Asian equities and rising oil prices intensified market pressure. QCP Capital analysts warned that if U.S. stocks continue to fall and trigger broader deleveraging, risks could spill over to the crypto market, and Bitcoin’s $80,000 support level may face a test. In terms of fund flows, U.S. spot Bitcoin ETFs recorded a net inflow of around $526.6 million on Monday, marking the highest level in a month. Among them, BlackRock’s IBIT saw a single-day net inflow of roughly $665.2 million, its largest daily inflow since October 2025; products from Fidelity and Grayscale, by contrast, posted outflows. In contrast, Ethereum spot ETFs saw a net outflow of $103.3 million, marking the fourth consecutive trading day of outflows, indicating recent buying demand is concentrated in Bitcoin rather than the broader crypto market. The macro environment remains under pressure: the U.S. 10-year Treasury yield stands at around 5.13%, Brent crude oil prices are near $110 per barrel, and rising energy prices have stoked inflation concerns. The Federal Reserve is expected to hold interest rates steady next week, but markets have priced in a 25 basis point rate hike next month. QCP noted that if U.S. Treasuries continue to rally, real yields fall, and the U.S. dollar weakens, it could provide support for risk assets; conversely, if U.S. stock sell-offs persist, Bitcoin’s $80,000 level will be a key watch point.
