Bitcoin and Wall Street Enter September Under a Long-Running Seasonal Shadow

Bitcoin is heading into another September marked by a historically weak seasonal record. The cryptocurrency has declined in eight of the past 13 Septembers, according to Decrypt, giving rise to the market’s “Red September” label. Wall Street has faced a similar pattern: the stock market has recorded the same September weakness since 1928. The trend was interrupted last year, when the usual pattern failed to hold, but the historical record remains a focus as the next September trading period begins. For Bitcoin investors and market watchers, the data highlights a recurring calendar effect rather than a forecast of a particular price move. The comparison with equities also places Bitcoin’s September performance within a broader market pattern, rather than treating it as an isolated crypto phenomenon.
