Bitcoin And The September Curse: Can This Time Be Different?

Bitcoin heads into the final days of August with choppy, two-way trade and a familiar seasonal question hanging over it: will September once again be a drag—or a reset into Q4 strength? As of Wednesday, August 28, BTC hovers near $112,900 after a stop-start month that has bulls and bears circling the same range rather than breaking ￰0￱ expectations, market positioning and Bitcoin’s own statistical quirks now converge in a narrow window before the Federal Reserve’s September policy meeting, making the next few weeks unusually ￰1￱ Fed’s rate-setting FOMC convenes September 16–17, and futures markets currently price a high probability of a cut, though officials continue to emphasize data-dependence.

Bitcoin’s September Seasonality Seasonality is the first prism through which traders are reading the ￰2￱ Crypto Trades captured the prevailing mood on X, noting a “choppy August” and pointing to a historical oddity: “During BTC’s history it has never closed both August & September in the green.” He added a pragmatic caveat about why this matters at all: “Whether you believe in seasonality or not, the thing that matters is if a lot of others ￰3￱ if enough people do, it can work as a self-fulfilling prophecy.” Related Reading: Bitcoin Selloff: $2.2 Billion In BTC Floods Exchanges Independent datasets support the caution around September. CoinGlass-based compilations show that across the past 12 years, September has delivered an average negative return for BTC of roughly 3.8%, making it the worst month on the ￰4￱ contrast, Q4—and especially October and November—has historically outperformed on average, a profile that helps explain why traders often look to buy late-Q3 weakness.

However, there is a silver ￰5￱ Bitcoin’s history, September has closed in the green on four occasions—most notably in 2015 and 2016, and again in recent ￰6￱ 2023, BTC gained 3.9%, followed by a 7.3% rise in ￰7￱ Pompliano offered a broader framing this week, starting with the simple, if stubborn, statistics: “September is actually the only month of the year that historically is negative.” He attributes the late-summer doldrums in part to investor behavior—“Everyone is on vacation… not in front of their screens”—and in part to unresolved macro questions from traditional finance. “There’s a lot of uncertainty still,” he said, even as “Jerome Powell has come out and said that he’s going to likely cut rates in September.” While markets have swiftly moved to price that outcome after the Jackson Hole speech, Fed officials have been careful to say the decision remains data-driven; major brokerages nonetheless shifted their base cases to a September cut following Powell’s labor-market warnings.

Pompliano’s second theme is about the path higher. A straight line from last November’s ~$69,000 to six-figure prices, he argued, would risk a “very big dump on the other side.” Instead, the market “wants… some sort of correction and resetting,” flushing leverage and “setting a foundation of the price.” He sketched a broad consolidation band—“call it $125,00 to maybe $110,000”—before buyers ￰8￱ is Bitcoin’s price going down?
