According to the announcement from Binance, the premium index for TradFi perpetual contracts, or TradFi Perps, with any US equity as the underlying will be excluded from the funding rate calculation at 2026-10-21 08:00 (UTC). Binance said the adjustment follows intermittent network connectivity issues affecting one of the largest US overnight alternative trading systems (ATS). The connectivity issues occurred from 2026-10-21 03:46 (UTC) to 2026-10-21 06:30 (UTC). The exclusion applies to the premium index for the affected time period and covers TradFi Perps whose underlying assets are US equities. The announcement identifies the ATS connectivity problems as the reason for removing that premium index from the funding rate calculation. The change is scheduled for 2026-10-21 08:00 (UTC), after the reported period of intermittent connectivity ended at 2026-10-21 06:30 (UTC). Binance’s announcement does not specify any other affected underlying assets or additional changes to TradFi Perps funding rate calculations.
