Bitcoin is up about 7% in September after gaining 25% in August, putting it on track for a third consecutive monthly advance. With two calendar days left in the month, a positive close would be the first time a positive August has been followed by a positive September since 2013. It would also leave the third quarter up more than 40%.
Why it matters
The streak would mark a break from a decade-long seasonal pattern, but it does not remove the macro risks facing Bitcoin. Global bond yields are rising, the U.S. 10-year yield is above 5.2%, and the MOVE index, which tracks bond-market volatility, is above 100 and approaching its year-to-date highs. Oil above $90 a barrel is adding to inflation concerns.
The fourth quarter has historically been Bitcoin’s strongest, with CoinGlass data putting its average gain at roughly 77%. That seasonal record is context, not a guarantee, particularly as markets face competing demands for liquidity and shifting risk appetite.
Market impact
Bitcoin is trading at $84,000. Gold fell about 3% on Monday to just above $4,000 an ounce, another sign of movement across markets as investors weigh the outlook for inflation and rates.
Two November events could add volatility in the fourth quarter: Anthropic’s reported IPO plans and the U.S. midterm elections. The IPO’s timing and size have not been finalized, while election-related policy uncertainty could influence investor positioning. Bitcoin’s monthly close and the response to the higher-yield environment will be key near-term signals for whether its run can carry into Q4.
