Binance will remove the premium index for all US equity-based TradFi perpetual contracts during a specific window from its funding rate calculation on October 21. The adjustment follows intermittent connectivity issues reported by one of the largest overnight alternative trading systems (ATS) in the United States between 03:46 and 06:30 UTC. The exchange stated that when settling funding rates at 08:00 UTC, the affected period's premium index data will be excluded entirely. This measure ensures that the technical disruption in the underlying market infrastructure does not distort funding payments for traders holding these positions.
