Overview

HKEX’s Severe Weather Trading (SWT) arrangements have been in effect since 2024.

Hong Kong’s securities and derivatives markets, including Stock Connect trading, derivatives holiday trading and after-hours trading session, will continue to operate according to the pre-determined trading calendar, regardless of severe weather conditions.

Overview

Hong Kong’s role as a leading international financial centre has strengthened by increasing participation of both international and Mainland investors.

To enhance Hong Kong’s competitiveness as a trading and risk management hub and an international financial centre, HKEX, under the support of the HKSAR Government and in consultation with regulatory authorities, has completed a market consultation and decided to keep Hong Kong's securities and derivatives markets open to provide trading, clearing and settlement services during severe weather conditions.

This initiative will make Hong Kong's markets available for local, mainland and international investors to respond to the latest global market development during Hong Kong's trading hours, including trading and risk management on index rebalancing days, regardless of the weather conditions.

To ensure safety, remote working and the use of online services are strongly encouraged on a SWT day, and no public-facing physical outlets should provide services.  HKEX has made some operational adjustments to ensure the market continues operating in a robust and resilient manner, as certain services provided only via physical outlets will be unavailable.

Investors should consult their respective brokers and banks on their service provisions under severe weather conditions.

HKEX is pleased to have received confirmations from all securities and derivatives market participants declaring their readiness to operate under SW conditions.

All EPs and CPs are expected to fulfil their day-to-day operational requirements (e.g. fulfilling settlement obligations and regulatory reporting, etc.) on a SWT day.
