August turned out to be a surprise month for bitcoin: contrary to a long-standing tradition, the asset finished it in the green, demonstrating an impressive gain of about 28% and returning above the $80,000 mark. However, it is too early to relax. Ahead lies September, historically one of the most treacherous months for the first cryptocurrency, and now the market is frozen in anticipation of a key trigger that will determine its fate until the end of the month.
Hawkish signal: why the market got nervous
The main catalyst for uncertainty is the fresh rhetoric from the head of the Federal Reserve System. After his speech in Jackson Hole, the probability of a rate hike at the September meeting jumped sharply from 45% to 60% in just one hour. The market heard a clear signal: a rate cut in the near future is unlikely, and inflation is still far from the target 2%.
The Fed points to a resilient labor market (unemployment around 4.1%) and rising corporate capital expenditures, largely fueled by the artificial intelligence boom. At the same time, the regulator's preferred PCE index still shows inflation at around 3.7%, which forces investors to demand a higher risk premium for assets sensitive to global dollar liquidity. Bitcoin, as the most volatile of them, finds itself on the front line.
Key dates and levels to watch
The fate of the market in September will be decided not in a single day, but by a series of important events. The first half of the month includes labor market reports (September 1 and 4), then the producer price index (September 10), and, most importantly, the August consumer price index CPI (September 11). It is these data that will set the tone ahead of the Fed meeting on September 16, where economic forecasts will be updated.
Do not forget about the Bank of Japan meeting on September 18, which could shake up carry trades, as well as the expiration of quarterly bitcoin options on September 25. According to the structure of open interest, it is clear that many traders are pricing in a drop to $70,000, which creates the ground for increased volatility and false breakouts in the second half of the month.
My analysis and forecast for bitcoin
The base scenario is consolidation in a wide range of $74,000–84,000. To move toward the lower boundary, an inflow of $400–800 million into spot ETFs would be enough, but to storm $84,000–85,000, $1.5–2.5 billion would already be required. I expect that before the CPI release on September 11, some investors will take profits after a strong August, which could lead to a pullback to $74,000–75,000 and even to $72,000. The further scenario depends entirely on inflation data: a weak CPI will return bullish momentum and a target of $80,000–84,000, while a high one will intensify the correction to $70,000–72,000.
It is important to understand: the historical average return of bitcoin in September is about −3%, but over the past three years the month has closed in the green. Relying only on seasonality is a mistake. The key signal will come precisely from macroeconomic statistics. My benchmark for the month is movement in a wide range with a downward bias in the first half and an attempt to return to $80,000+ in the second, if inflation data does not deliver unpleasant surprises.
