U.S. spot Bitcoin exchange-traded funds attracted $2.386 billion in net inflows during the five trading days through Sept. 25, marking their strongest weekly intake in nearly a year despite a volatile backdrop for Bitcoin and other risk assets. BlackRock's IBIT led weekly inflows with $1.158 billion, followed by Fidelity's FBTC with $702 million, while total spot Bitcoin ETF net assets stood at $108.42 billion and cumulative net inflows reached $57.55 billion. Bitcoin later fell from about $84,500 to $82,800 as investors reduced exposure across equities, gold and crypto, QCP said. The firm linked the broad deleveraging to renewed concern over energy supplies after the U.S. rejected a proposed ceasefire condition related to the Strait of Hormuz, while rising oil prices reinforced inflation concerns. Investors are also watching the Personal Consumption Expenditures price index and U.S. nonfarm payrolls report following a recent Federal Reserve rate increase. QCP said short-dated crypto-options implied volatility remained elevated and downside protection was in demand, while spot Bitcoin ETF flows showed hesitation amid wider liquidations.
