The US Treasury market is experiencing significant volatility, with the MOVE Index, a measure of implied volatility, reaching its highest level in ten months. The 10-year Treasury yield has surged to 4.25%, the highest since July, driven by investor anticipation of a potential Republican victory in the upcoming election. This rise in yields is putting pressure on the stock market, with the S&P 500 experiencing its largest daily drop since September 6th. The Dow also ended down 400 points, suffering its worst day in a month. Bond market volatility has increased, with the MOVE Index climbing from 90 to 129 in less than a month. Analysts attribute these movements to concerns over potential budget deficits and economic policies under a possible GOP administration.
