As of September 25, 2026, the MOVE index, which measures expected volatility in the U.S. Treasury market, has surged from about 80 on Tuesday to 104, marking its highest point since March. This increase is driven by rising energy prices and bond yields, further intensifying inflation concerns.

In contrast, the volatility indices for bitcoin and the S&P 500 remain relatively stable. The 20-day correlation between the MOVE and the Cboe VIX indices has turned slightly negative for the first time since April 2024, indicating that rising volatility in the bond market has not yet permeated equity markets.

The current bond market signals caution about potential impacts on bitcoin and U.S. stocks. The annualized 30-day bitcoin implied volatility index, BVIV, is at around 37, close to its year-to-date low of 35, reflecting subdued expectations among bitcoin options traders. The Cboe VIX, which gauges expected volatility in the S&P 500, is similarly low, hovering near its own year-to-date low of 14.

This divergence suggests underlying resilience in both bitcoin and stock markets, despite the escalating volatility in Treasury notes. Typically, higher volatility in Treasuries can tighten financial conditions and deter risk-taking in other markets.

Compounding these dynamics, escalating government bond yields globally are influenced by the ongoing conflict in the Middle East, which has driven up oil and diesel prices, complicating the overall inflation outlook. The U.S. 10-year Treasury yield briefly reached 5.2% on Thursday before settling at 5.163%.

In March, when the MOVE index was last at a similar level, the S&P 500 was near 6,350; it has since climbed to 7,704, a rise of approximately 21%. However, bond traders are now paying significantly more for protection against fluctuations in interest rates.

The correlation between VIX and MOVE has slipped to -0.06, a notable decline, while the correlation between BVIV and MOVE is at -0.37, one of its lowest in years. Despite the increased volatility in bonds, bitcoin's expected volatility remains near a yearly low. According to CoinDesk, rising yields have shown little consistent relationship with bitcoin's returns.
