Bitcoin stalls under $80,000 as yields near 5% and stocks rise

Bitcoin failed to break $80,000 on Sept. 11 and traded around $77,000 as U.S. equity indexes closed higher. The S&P 500 gained nearly 1%, with the Dow and Nasdaq also rising. The 10-year Treasury yield briefly reached 4.9915%, its highest in almost three years, and the 30-year hit 5.424%, a 19-year high, before both yields pulled back modestly to about 4.95% and 5.341%.

Options markets showed elevated near-term volatility ahead of the Federal Reserve’s Sept. 15–16 meeting. At-the-money implied volatility for Bitcoin options expiring on Sept. 12 was near 46%, compared with roughly 38%–40% across later expiries. Trading activity concentrated in Sept. 12 calls at $78,500 and $80,000 and in $75,000 puts expiring on Sept. 11 and Sept. 18.

A trading desk identified support in the $76,300–$76,500 band and resistance in the $80,000–$82,000 range. The desk noted that a sustained move below the support band could shift attention to downside protection around $75,000, while a confirmed move above $80,000 would test the higher resistance area.

August inflation data showed core consumer prices up 0.3% month over month and headline inflation up 0.4%. Market pricing put about an 85% probability on a 25 basis point policy rate increase at the Fed’s Sept. meeting.

Bitcoin’s market capitalization was near $1.55 trillion with a circulating supply of about 20.08 million coins. The token recorded a notable 30-day gain even as near-term price action cooled.

Market participants said a weekend price break could set an initial direction for spot markets, but they expected the Fed decision and updated economic projections to be the decisive event for identifying the driving factor behind any sustained move.
