Bond volatility surges while bitcoin and Wall Street stay calm

The market's measure of expected moves in U.S. Treasuries has climbed sharply this week, with the MOVE index rising from roughly 80 on Tuesday to 104 on Thursday, marking its strongest reading since March. The pickup in bond-market volatility comes as global government yields have been moving higher and energy prices have risen, factors that complicate the inflation outlook. Despite the jump in MOVE, volatility gauges for equities and bitcoin have remained muted. Volmex’s annualized 30-day bitcoin implied volatility index (BVIV) sits around 37, close to its year-to-date trough of 35, while the Cboe VIX for the S&P 500 is trading near its YTD low of about 14. Those readings indicate limited demand for option-based protection in those markets even as bond traders pay more for rate-swing insurance. The 20-day correlation between MOVE and the VIX has slipped into slightly negative territory at roughly −0.06, the first negative reading since April 2024, though it remains near zero. The relationship between MOVE and BVIV is more notably negative at −0.37, among its weakest readings in recent years. Together, those correlations show that rising Treasury volatility has not yet propagated to expected volatility in equities or bitcoin. Observers point to several drivers behind the divergence. The war in the Middle East has pressured oil and diesel prices higher, adding to inflation concerns and prompting a re-evaluation of how far central banks may need to tighten. The U.S. 10-year Treasury yield briefly touched 5.2% on Thursday before settling around 5.163%. Historically, elevated bond volatility can tighten financial conditions and temper risk-taking, but so far equities and bitcoin have preserved relatively low implied volatility amid the shift in rates. When MOVE was last around current levels in March, the S&P 500 was near 6,350; it has since climbed to about 7,704, an increase of roughly 21%. That contrast underscores how market dynamics have evolved since March: bond traders are paying more for protection against interest-rate swings, while option markets tied to stocks and bitcoin remain comparatively calm.
