Bitcoin has moved through more than half of September, historically one of its weakest months, yet the usual seasonal selloff has remained relatively limited despite several major policy and macroeconomic challenges.
After gaining around 25% in August and reaching approximately $81,000, many expected Bitcoin to give back a significant portion of those gains in September. Since 2013, Bitcoin has recorded an average decline of roughly 3% during the month.
So far, however, Bitcoin is down only about 1.5% in September. With less than two weeks remaining in the quarter, BTC is up approximately 32% for the quarter and is on track for its first positive quarterly close since Q3 2025.
Bitcoin is currently trading near $78,000, close to the level it held before Wednesday's Federal Reserve rate decision.
The Market's Lack of Reaction Is Significant
Two major developments this week could normally have triggered a much larger move in Bitcoin's price.
The Clarity Act failed to receive the 60 Senate votes required to move forward, securing only 49 votes. Bitcoin briefly dropped below $74,887 on Tuesday before quickly stabilizing.
The Federal Reserve then increased interest rates by 25 basis points to a range of 3.75%-4.00%, marking its first rate increase since July 2023.
Mitchell Askew, head of Blockware Intelligence at Blockware, highlighted Bitcoin's limited reaction to both events. He noted that a rate hike and the failure of the Clarity Act would normally create significant selling pressure in a weaker market, yet Bitcoin showed relatively little movement.
Seller Exhaustion Could Explain the Resilience
Askew interprets Bitcoin's limited reaction as a potential sign of reduced selling pressure rather than strong new demand.
His view is that investors who wanted to sell because of negative developments may have already exited their positions. If that is the case, fewer remaining holders may be willing to sell, potentially creating a more stable market environment.
Market positioning provides some support for this interpretation. Santiment data showed BTC-denominated open contracts falling 13.5% between September 3 and September 11, while Bitcoin's price declined about 5%. This left positioning roughly 20% below its pre-rally level.
K33 Research also reported that open interest across Bitcoin futures and perpetual contracts remained below its yearly average.
However, there is another possible explanation. Lower positioning could also indicate a lack of buyers rather than exhausted sellers. Talos reported that Bitcoin buying conviction had fallen to 3% from 10%, while positioning showed a 28% net shift toward stablecoins ahead of the Federal Reserve decision.
This distinction is important because exhausted sellers and absent buyers can create a similar price chart while pointing toward very different future conditions.
Multiple Macro Headwinds Hit the Market
Bitcoin's resilience came despite several additional pressures across global markets.
WTI crude oil moved above $106 on Tuesday, reaching a five-month high as tensions in the Middle East continued. Saudi Arabia's closure of the East-West pipeline, which provides an alternative route around the Strait of Hormuz, contributed to production falling to 6.238 million barrels per day, the lowest level since 1990.
The U.S. Dollar Index also moved above 100, reaching its highest level in more than a month. Persistent dollar strength can tighten financial conditions and put pressure on risk-sensitive assets.
Meanwhile, the Bank of Japan raised its benchmark interest rate to a 31-year high, increasing the cost of the yen carry trade that has historically supported positions in dollar-denominated assets.
Rising Yields May Not Automatically Be Negative for Bitcoin
Fabian Dori, chief investment officer at Sygnum Bank, offered a different interpretation of the relationship between interest rates and Bitcoin.
According to Dori, higher yields do not necessarily mean that Bitcoin and other store-of-value assets must decline. If rising rates reflect concerns about currency debasement or sovereign risk, investors may instead increase exposure to assets such as Bitcoin and gold.
Bitcoin's recent correlation data also highlights the difference between the two assets. Its 90-day correlation with the 10-year U.S. Treasury yield stands at approximately -0.17, compared with -0.41 for gold.
Markets are currently pricing in three additional quarter-point rate increases by April 2027, potentially taking the federal funds rate to 4.50%-4.75%.
Dori argues that digital assets do not necessarily require falling interest rates to outperform.
Regulatory Developments Shifted Shortly After the Senate Vote
The regulatory environment saw another major development less than two days after the Senate vote.
The SEC introduced its long-awaited innovation exemption for tokenized securities platforms on Thursday. Under specified conditions, qualifying platforms can facilitate onchain trading of stocks.
SEC Chairman Paul Atkins had previously indicated that the agency could take action within its existing authority regardless of whether the legislation passed.
LMAX Group markets strategist Joel Kruger said the failure to advance the legislation delays the creation of a formal statutory framework, but does not prevent the SEC and CFTC from continuing to provide regulatory guidance under their existing authority.
The main uncertainty is durability. Regulations established through existing agency authority can potentially be changed by a future administration, while legislation would provide a more permanent statutory framework.
Bitcoin's Resilience Could Create an Asymmetric Setup
Kruger argues that Bitcoin's ability to remain stable during a difficult news cycle could become important if macroeconomic, geopolitical, or regulatory conditions improve.
His argument is based on the relatively limited downside reaction to recent negative developments. If conditions become more supportive, even a moderate improvement could potentially provide a catalyst for stronger market momentum.
The Federal Reserve's latest projections also provided some room for interpretation. The median projection indicates one additional rate increase in 2026, totaling 50 basis points, compared with the 75 basis points expected by Bank of America and RBC and approximately 87.5 basis points previously priced into markets.
September Seasonality Remains a Short-Term Risk
Historical seasonality remains one of the main concerns for Bitcoin in the near term.
According to CoinGlass, Bitcoin has historically declined an average of 2.5% during the year's 38th week and has recorded gains during that week on only four occasions.
However, the longer-term seasonal pattern tells a different story. CoinDesk data shows that Bitcoin has historically averaged a 77% gain during the fourth quarter.
These figures are based on relatively small historical samples and should not be treated as forecasts. The seasonal data simply presents two opposing historical patterns: potential weakness during the coming week and historically stronger performance during the fourth quarter.
The $80,000-$82,000 Zone Remains Important
Bitcoin's price structure also shows a significant concentration of supply around the $80,000-$82,000 range.
Glassnode data indicates that nearly 8% of Bitcoin's circulating supply was acquired between $80,000 and $82,000. The average cost basis of U.S. spot Bitcoin ETF investors is also around this area, while the 50-week moving average currently sits near $81,081.
For now, Bitcoin's ability to remain relatively stable despite several negative macroeconomic, monetary, and regulatory developments remains a key feature of the current market environment. The next major signals are likely to come from price behavior around the $80,000-$82,000 area, upcoming macroeconomic developments, and changes in market positioning.
Conclusion
Bitcoin has entered the latter part of September with a relatively limited decline despite historically weak seasonality and several significant market headwinds. The failure of the Clarity Act, higher interest rates, stronger oil prices, a firmer U.S. dollar, and tighter global monetary conditions have not produced the level of selling pressure that might normally be expected.
Whether this resilience reflects seller exhaustion, limited market participation, or a combination of both remains uncertain. Meanwhile, regulatory developments and Bitcoin's position near the $80,000-$82,000 supply zone could play an important role in determining the market's next direction.
