The fixed-income market is sending out an alarm that neither bitcoin nor equities in the United States have acknowledged yet.
According to information from CoinDesk, the MOVE index, which gauges anticipated volatility within the U.S. Treasury sector, escalated from roughly 80 on Tuesday up to 104 by Thursday, marking its peak point since March when it reached 199.
Volmex’s 30-day annualized bitcoin implied volatility index, known as BVIV, stays muted at approximately 37, sitting near its yearly low of 35. This metric captures options speculators’ projections regarding bitcoin price fluctuations across a four-week horizon. Concurrently, the Cboe VIX, which tracks expected fluctuations for the S&P 500, trades near its low for the year of 14. Neither asset class exhibits a matching hunger for volatility.
This divergence highlights an underlying resilience in both bitcoin and equities. Heightened turbulence in Treasury notes—which serve as the foundation for global finance and credit creation—typically tightens monetary conditions and discourages risk appetite across financial markets.
This split occurs as sovereign bond yields rise worldwide. The conflict in the Middle East has pushed petroleum and diesel costs higher, complicating the inflation outlook and fueling debates over how much further central banking institutions may need to restrict monetary policy. On Thursday, the 10-year U.S. Treasury yield touched 5.2% before receding to 5.163%.
When the MOVE index last hovered around this bracket back in March, the S&P 500 sat close to 6,350. It has since climbed to 7,704, marking a gain of about 21%. Nevertheless, debt traders are currently paying significantly steeper prices to hedge against interest rate swings.
Over a 20-day timeframe, the statistical link between the VIX and the MOVE has dropped to −0.06, dipping into negative territory for the initial time since April 2024, although that figure remains near zero. The correlation between the BVIV and the MOVE reads more decidedly negative at −0.37, representing one of its lowest marks in years. While fixed-income instability has escalated, bitcoin’s projected price turbulence has stayed close to its annual nadir.
