Odaily News Arthur Hayes, co-founder of BitMEX, wrote on the X platform that if investors want to predict when the Fed will restart easing, they should pay attention to the bond market volatility indicator MOVE index. When MOVE rises, traders who buy U.S. bonds or corporate bonds with financing will face higher margin requirements and be forced to close their positions. He said that once MOVE breaks through 140, the Fed may intervene in the market.
