The upcoming Federal Reserve interest rate decision has prompted an increase in short positioning on BTC futures traded on the CME. According to a report by Arcane Research analysts Vetle Lunde and David Zimmerman, this cautious positioning indicates that crypto investors are preparing for potential market volatility. Currently, the market anticipates a 65% likelihood of a 50 basis point rate hike by the Fed. This anticipation has likely contributed to the increase in short positions, as investors seek to hedge against potential downside risk.
