Bitcoin enters September caught between solid institutional demand and tightening macroeconomic headwinds, with market makers and analysts watching key technical and policy levels. According to crypto market maker Wintermute, BTC is likely to remain confined to a trading range between $75,000 and $82,000 until the U.S. Federal Open Market Committee meeting scheduled for September 15–16.
Wintermute noted that selling pressure has repeatedly emerged near $82,000, while support sits at $75,000 and $72,000. A weekly close below $72,000 would remove a clear downside reference and could spark volatility. The firm added that spot Bitcoin ETF inflows have been the primary driver of the recent rebound, and its rangebound outlook would be challenged by weekly net outflows from ETFs or a break of the $72,000 floor.
A separate weekly report from Bitfinex reinforced this cautious tone. Bitcoin briefly climbed above $81,000 before retreating after Federal Reserve Chair Kevin Warsh struck a restrictive tone at the Jackson Hole gathering. The world’s largest cryptocurrency nevertheless held above the $77,100 support level, preserving a structure of higher highs and higher lows.
Bitfinex highlighted that U.S. spot Bitcoin ETFs attracted nearly $1 billion in net inflows last week, while Ethereum investment products pulled in $815.7 million and extended a ten-session positive streak. The report said August’s advance was driven mainly by spot purchases rather than excessive leverage, with gradual open interest growth and contained basis. Large holders reduced balances from late June, while custodial wallets tied to exchanges and ETF platforms increased, suggesting a rotation toward institutional structures.
Still, macro conditions remain the main constraint. The PCE inflation gauge stands at 3.7%, with the core reading at 3.3%, while private domestic demand expanded at an annualized 4.2% in the second quarter. The federal deficit reached $1.8 trillion through the first ten months of fiscal 2026, adding pressure to borrowing costs. Markets now assign a 57% probability to a September rate hike, and Warsh affirmed that the 2% inflation target is a firm constraint. The next major test will be August labor market and inflation data, which could confirm whether structural crypto demand remains intact.
