Binance said its October 21 stock-futures funding calculation would exclude observations affected by an overnight connection problem. The adjustment covered its US-equity perpetual futures and targeted the inputs used to determine payments between opposing traders.
The exchange’s October 21 notice reported intermittent network connectivity problems at an unnamed US overnight alternative trading system from 03:46 to 06:30 UTC that day. It said premium-index data for the affected period would be removed from the 08:00 UTC funding-rate calculation for all TradFi perpetuals with US equities as their underlying assets.
How stock-futures funding payments work
Under Binance’s funding methodology, funding is a periodic transfer between holders of long and short perpetual positions. When the rate is positive, longs pay shorts; when it is negative, shorts pay longs. Binance says it charges no fees on these transfers. The amount depends on the position’s nominal value multiplied by the applicable funding rate.
The premium index is part of that rate calculation. It compares prices at which a specified amount could be bought or sold in the futures order book with a reference price index. Binance then averages premium observations over the applicable funding period.
Excluding the affected observations would change that input set. The announced intervention therefore addressed the data used to calculate funding, rather than promising to cancel the payment itself.
The timing sits within the broader challenge of offering equity derivatives around the clock. Binance’s TradFi perpetuals guide describes interrupted underlying-market schedules, vendor-based reference prices and session-dependent smoothing. During specified market closures, order-book-derived inputs are used. These are general pricing mechanics; the incident notice specifically targeted affected premium-index observations.
Funding also serves a different purpose from the mark/index relationship and stock-token collateral valuation covered in CryptoSlate’s recent Binance reporting. Those mechanisms concern how positions or the assets backing accounts are valued, rather than the periodic transfer between opposing positions.
Binance’s notice did not disclose resulting rates, payment amounts or customer-loss figures, and made no compensation commitment.
