Instant conclusion: Binance Perpetuals ONEUSDT U-margined contracts. Starting tonight, Binance will end the “Last Protected Price” (LPP) period; the mark price will gradually revert to the standard calculation.

According to the Binance official announcement: Beginning at 2026-09-17 14:00 (UTC) / 22:00 (UTC+8), ONEUSDT will end LPP. The mark price will smoothly transition from LPP to the standard formula (using the median of Price 1, Price 2, and the contract price). The transition will last up to about 3 hours, depending on volatility and whether the index stabilizes; trading is not affected during this period, and open orders and positions will not be cancelled.

Funding fee calculation updated in parallel: the cap is adjusted back from ±0.005% to the standard ±2.00%. In the table, the value shown at 08:00 UTC remains ±0.005%, and from 16:00 UTC it becomes ±2.000%. When a funding fee settlement reaches ±2.00%, the funding fee settlement interval changes from every 4 hours to every 1 hour. Contract parameters may be adjusted according to market risk; products and services vary by region.

Independent verification: Odaily and Coinlive reports on the same day match the effective time, the maximum ~3-hour transition, that trading/positions are unaffected, and the funding fee upper/lower limits and the 4h→1h trigger rule.
