HKEX extends overnight derivatives trading as Hong Kong chases global market flow

Bourse operator Hong Kong Exchanges and Clearing (HKEX) is taking a further step towards round-the-clock trading by pushing back the closing bell for its after-hours derivatives market by 75 minutes from next year, according to a statement released on Monday.

The derivatives After-Hours Trading (AHT) session would extend to 4.15am from 3am, Hong Kong time, starting in March 2027, subject to regulatory approval and system readiness, according to HKEX. It added it was also considering a further extension to 5.15am by November 2027. The AHT session starts at 5.15pm.

Separately, HKEX announced on Monday that it had begun accepting Bond Connect securities and Ministry of Finance bonds as eligible non-cash collateral, broadening collateral choice and supporting liquidity management, as part of efforts to extend Hong Kong’s offshore yuan ecosystem.
