What changed
HKEX has issued a circular establishing the trading arrangements for 25 May 2026, designated a Holiday Trading Day due to coinciding UK and US bank holidays. The key change from standard operations is the suspension of after-hours trading for all equity index products listed on HKATS, including MSCI Taiwan, MSCI China A 50 Connect, MSCI China, MSCI Philippines, MSCI Vietnam, MSCI India, MSCI Indonesia, and MSCI Malaysia futures and options. Currency products, however, will continue to trade after-hours under standard hours. Non-Holiday Trading Exchange Contracts will have no trading activity on that date.
Exchange Participants and their clients who trade equity index futures and options on HKEX should plan accordingly for the absence of after-hours trading sessions on 25 May 2026. Firms should update their trading systems, risk management parameters, and client communication protocols to reflect the modified hours. Staff responsible for trading operations and client advisory should be briefed on the specific product-level distinctions between holiday-affected and unaffected contracts.
What to do next
- Notify clients of the after-hours trading arrangement on 25 May 2026
