On December 8, HKEX announced that it will optimize the collateral arrangements for its subsidiary, Hong Kong OTC Clearing Limited (OTC Clearing), effective January 2, 2026.

Aligning with the enhancements implemented by HKEX's other stock and derivatives clearing houses on October 2, 2025, OTC Clearing will revise the interest arrangements for cash collateral (i.e., margin balances) provided by clearing members to meet margin requirements.

Interest, if applicable, will be calculated daily based on the reference rate of the respective currency, net of corresponding handling fees. The handling fee will be set at 0.8% per annum starting January 2, 2026, decreasing by 10 basis points annually until it reaches 0.5% per annum from January 2, 2029.
