Bitcoin, Bonds, and Stocks Face September Risks Amid Midterm Election Year

September has traditionally been a volatile month for Wall Street, especially during U.S. midterm election years. Historical data shows that the average stock‑market low across the last ten midterm cycles occurred around September 2, with an average decline of 16.77% from the preceding high.

Midterm Election History and Market Lows

Hartford Funds examined ten midterm election years from 1986 to 2022. Each cycle saw a notable drop in equities after the yearly peak. The magnitude varied: the S&P 500 fell 33.75% in 2002, while the decline in 2014 was only 7.40%. The timing of the lows also differed, making September 2 an average reference point rather than a fixed deadline.

Current Market Context (2026)

In 2026, the S&P 500 remains near record highs, while long‑term U.S. Treasury yields stay elevated. The 30‑year Treasury yield reached 5.28% on August 21 and was around 5.20% at the end of August, compared with an effective federal funds rate of 3.63%.

Federal Reserve Stance

Federal Reserve Chair Kevin Warsh emphasized a continued focus on reducing inflation, reaffirming the 2% target as “firm and fixed.” Recent remarks highlighted a 12‑month PCE price index of 3.7% and a six‑month pace of 4.1%, indicating accelerating price pressures. Several Fed presidents have already voted for a rate hike in July, and market participants assign roughly a 53% probability to a September hike.

Bitcoin’s Position

Bitcoin entered September near $77,500, briefly reaching an $80,000 ceiling after a strong weekly gain driven by spot ETF buying. The cryptocurrency remains about 37% below its October 2025 peak of $126,080. The broader crypto market’s total value slipped 0.80% to approximately $2.66 trillion.

Potential Risks

• Historical midterm patterns suggest a possible equity drawdown in early September.
• A hawkish Fed stance could sustain higher bond yields and pressure risk assets.
• Bitcoin’s recent rally stalled, and a further decline could mirror the 2022 downtrend that saw a 65% drop to $15,500.

While past midterm cycles have also shown an average post‑low S&P 500 gain of 27.80% in the following year, the convergence of election‑related seasonality, elevated yields, and a cautious Fed creates a notably risky environment for September 2026.
