Bitcoin retreated from levels above $80,000 to approximately $79,200, marking a decline of roughly 2% within the trading session.U.S. equity markets experienced modest losses. Treasury yields edged upward in response.Market participants increased their assessment of a September rate hike probability to 42%, rising from 35% just one day prior, based on CME FedWatch tool readings.Betting markets on Polymarket reflected a 68% likelihood the Federal Reserve will implement at least one rate increase before year-end, climbing from below 50% during the preceding week.Current market pricing suggests approximately even odds—around 50%—for a 25 basis point increase at the September policy meeting versus maintaining the status quo.Upcoming August CPI and PPI releases scheduled before the September FOMC gathering are anticipated to significantly influence the committee’s ultimate decision.The annual Jackson Hole symposium has traditionally served as a platform for Federal Reserve chairs to telegraph major policy direction changes, which amplified attention on Warsh’s commentary.Treasury Secretary Scott Bessent introduced additional uncertainty last week by pledging to intervene in Treasury markets in an attempt to constrain long-dated interest rates.Warsh has typically advocated for market-determined interest rates, while Bessent contends that market distortions are driving long-term borrowing costs unnecessarily higher.Market participants will now focus intensely on August inflation reports scheduled for release prior to the September Federal Open Market Committee policy decision.The post Fed’s Warsh Sounds Alarm on Persistent Inflation as Bitcoin (BTC) Tumbles appeared first on Blockonomi.
