Binance Futures Ends Last Price Protection on HUSDT Perpetual Contract

Binance Futures to Phase Out Last Price Protected Mechanism

Binance Futures announced today that it will be discontinuing the Last Price Protected (LPP) period for its USDⓈ-Margined HUSDT Perpetual Contract. The change will see the contract’s Mark Price gradually transition from the LPP mechanism to a standard Mark Price calculation.

The transition is scheduled to commence on June 18, 2026, at 09:45 UTC. Binance anticipates the transition period could last up to three hours, depending on market volatility and the availability of a stable index price. To mitigate abrupt price fluctuations and ensure stability, the process will involve a mark price smoothing technique. Trading operations will remain unaffected throughout this period, and existing open orders and positions will not be canceled.

New Mark Price Calculation and Funding Rate Adjustments

Upon the conclusion of the LPP period, the Mark Price will be determined using the following formula:

Mark Price = Median (Price 1, Price 2, Contract Price)

Users can find the specific formulas for Price 1 and Price 2 within the Mark Price and Price Index documentation for USDⓈ-Margined Futures.

Following the end of the LPP period, the funding rate will adhere to the standard rules for perpetual futures contracts. The capped funding rate will be adjusted from the current ±0.005% to ±2.00% at 09:45 UTC on June 18, 2026.

The funding rate adjustments will occur as follows:

• June 18, 2026, 08:00 UTC: Maximum Funding Rate: +0.005% / -0.005%
• June 18, 2026, 12:00 UTC: Maximum Funding Rate: +2.000% / -2.000%
• June 18, 2026, 16:00 UTC: Maximum Funding Rate: +2.000% / -2.000%
• June 18, 2026, 20:00 UTC: Maximum Funding Rate: +2.000% / -2.000%

The funding interval will also be adjusted from every four hours to every hour once the previous funding rate settlement reaches ±2.00%.
