Bitcoin (BTC) ETF Outflows Hit $462.7M as Fed Decision Looms

Spot Bitcoin ETF Outflows Reach $462.7M

Bitcoin (BTC) ended last week down 3.8%, underperforming Ethereum (ETH) and several top altcoins, and the clearest source of selling pressure sat in the US ETF complex. Aggregate flow data shows US spot Bitcoin ETFs posted net outflows on every trading session from Sept. 8 through Sept. 11, for a combined $462.7 million in weekly net redemptions. The tape was holiday-shortened — US markets only reopened on the Tuesday after Labor Day — so the fund count covers just four sessions, yet all four printed outflows. Ethereum ETFs told the opposite story, drawing $197.1 million of net inflows over the same window, a rotation that kept overall Bitcoin market sentiment fragile while risk appetite migrated elsewhere in crypto. The pressure now runs straight into a packed policy week: the Fed's FOMC convenes Sept. 15-16, the Bank of England decides on Sept. 17 and the Bank of Japan meets Sept. 17-18. CME FedWatch pricing puts the probability of a 25-basis-point US hike at 87.3%, while Polymarket — where a recent Yale study found 3% of traders capture 27% of Bitcoin betting profits — splits 43% on September being the only hike this year against 41% for two moves totaling 50 basis points. In the UK, a hold at 3.75% is the base case, a sixth consecutive pause with Hugh Pill, Catherine Mann and Megan Greene tipped to dissent in favor of a hike. Japan's 72.8%-priced lift to 1.25% would push borrowing costs to their highest since April 1995. With WTI front-month crude near $99.99, the inflation backdrop is unlikely to soften before any of the three votes — see our companion piece on Goldman Sachs Expects 25bp Fed Rate Hike on Sept. 16.

AI Slowdown Calls and a Hot August PPI

The softness carried through the weekend. On Japanese pairs, BTC slipped below the ¥12 million line and last traded around ¥11.87 million — down just 0.10% over 24 hours but 4.7% across seven days, with dollar quotes near $77,200 on Sept. 13, per the live BTC/USD chart. The wider picture is firmer than the week suggests: BTC remains up 22.34% over 30 days, so the recent dip sits inside a broader monthly recovery rather than a fresh downtrend. Two new overhangs explain the hesitation. The first is AI sentiment. On Saturday, Anthropic chief Dario Amodei called for a slower pace of model development and the use of independent third-party evaluators, and OpenAI's Sam Altman publicly aligned with him, saying safety concerns would push OpenAI's planned IPO back to 2027. Bitcoin has traded in recent months as a high-beta expression of the AI-capex narrative, so doubts about that spending pipeline transmit to crypto quickly. The second is producer inflation. The Bureau of Labor Statistics' August PPI, released Sept. 10, rose 0.4% month-on-month on a seasonally adjusted basis and 5.4% year-on-year unadjusted, with goods prices up 1.1% — energy, up 4.2%, accounted for more than three-quarters of that goods increase. With the FOMC statement due Sept. 16, the first real-time gauge of how markets digest the combination will be Monday's session in US tech equities, the proxy risk asset that has tracked BTC most closely this month.

Stablecoin Liquidity Waits Out the Fed

The thread linking both developments is caution, not capitulation. COINOTAG's aggregate market data shows capital still parked inside crypto: our tracked universe stands at $2,288,792,587,897, BTC holds a 68.1% share of it, stablecoin supply has swollen toward $309 billion, and the Fear & Greed Index reads 57 (Greed). Long-term holders — many in since the last halving — appear content to hodl through the policy fog; a Fed that avoids signaling prolonged tightening should let that idle liquidity rotate back into BTC, while a hawkish surprise keeps it sidelined.
