Wintermute Reports First BTC ETF Net Outflows Since June

Wintermute reported that BTC ETFs saw $463 million in net outflows for the week ending September 14, the first negative reading since June. ARK and Grayscale accounted for $371 million in outflows, while BlackRock remained flat. BTC fell 4.4% to $76,838, while ETH dropped 1.5%. Macro factors, including higher-than-expected US CPI and PPI data, have led Goldman Sachs to shift its forecast to a rate hike, with markets pricing in an 87% probability of a 25bp increase this Wednesday. Wintermute maintains a neutral stance. Key upcoming events include the US Senate procedural vote on the CLARITY Act (US digital-asset market-structure bill) on Tuesday and the Federal Reserve's rate decision on Wednesday.
