Bitcoin has retreated to approximately $83,500 following a pullback from $87,000, remaining roughly 33% below last October's peak. U.S. spot BTC ETFs recorded net outflows of $679 million last week, including a single-day withdrawal of $485 million on Wednesday that marked the largest since June. ETH ETFs also saw cumulative outflows nearing $700 million over nine consecutive trading days. Macro headwinds are intensifying with the 10-year Treasury yield reaching 5.37%, its highest level since 2002, while markets price in a 20% probability of an October rate hike. Bitcoin’s correlation with the Nasdaq has returned to its long-term average of 40%. CoinShares identifies this week's CPI release as the critical near-term catalyst; a core CPI increase of 0.3% could reinforce rate-hike expectations and risk retesting $80,000 support, while a 0.2% reading or lower would favor delaying action until December.
