Notice on Adjustments to Price Limits and Trading Margin Standards for Futures Contracts During the 2025 Labor Day Holiday

GFEX Notice [2025] No. 154

To All Member Units:

In accordance with the "GFEX Risk Management Measures," after careful consideration, the exchange has decided to adjust the price limits and trading margin standards for various futures contracts before and after the 2025 Labor Day holiday as follows:

Starting from the settlement on Tuesday, April 29, 2025, the price limit for silicon metal futures contracts will be adjusted to 8%, the speculative trading margin standard to 10%, and the hedging trading margin standard to 9%. The price limit for polysilicon futures contracts will be adjusted to 9%, the speculative trading margin standard to 11%, and the hedging trading margin standard to 10%. The price limit for lithium carbonate futures contracts will be adjusted to 10%, the speculative trading margin standard to 12%, and the hedging trading margin standard to 11%.

After trading resumes on Tuesday, May 6, 2025, starting from the settlement on the first trading day when the futures contract with the largest open interest for each variety does not experience a unilateral price limit without continuous quotations, the price limits, speculative trading margin standards, and hedging trading margin standards for the aforementioned futures contracts will revert to their pre-adjustment levels.

If the aforementioned price limits and trading margin standards differ from the currently implemented price limits and trading margin standards, the larger price limit and higher margin standard shall apply.

This is hereby notified.
