Binance announced that the Last Price Protected (LPP) period for the USDⓈ-Margined ONEUSDT Perpetual Contract will end at 2026-09-17 14:00 UTC. The Mark Price will gradually transition from the LPP mechanism to the standard calculation through a smoothing process intended to reduce abrupt price movements. The transition may take up to three hours, depending on price volatility and the availability of a stable index price. Trading will not be interrupted, and open orders and positions will not be canceled.
After the LPP period ends, the Mark Price will be determined by the function Median(Price 1, Price 2, Contract Price), with Price 1 and Price 2 defined by the formulas used for Mark Price and the Price Index in USDⓈ-Margined Futures.
The funding rate will also transition to the standard perpetual futures rules once the LPP period ends.
The capped funding rate for the ONEUSDT perpetual will change from +0.005% / -0.005% to 2.00% / -2.00% at 2026-09-17 14:00 (UTC). The schedule shows the maximum funding rate at 2026-09-17 08:00 (UTC) remaining at +0.005% / -0.005%, before increasing to +2.000% / -2.000% at 2026-09-17 16:00 (UTC), 2026-09-18 00:00 (UTC), and 2026-09-18 08:00 (UTC).
Binance stated that the funding interval will be adjusted from every four hours to every one hour once the previous funding rate settlement reaches +2.00% / -2.00%.
The notice also said that Binance may adjust contract specifications over time, including funding fee, tick size, maximum leverage, initial margin, and maintenance margin requirements, based on market risk conditions.
