With mainland markets and Stock Connect shut on the final day of the Trump-Xi summit, Hong Kong equities and the offshore yuan become the main channel for pricing any China-related headlines. Thinner cross-border flows can amplify moves in Hong Kong-listed China names, since southbound mainland buying is absent. The compressed three-day window before the National Day break raises the odds of pre-holiday de-risking in mainland assets. Commodity traders should note the pause in Shanghai futures, which removes a key source of Asian-hours price discovery for metals and energy through both holidays.

China’s markets take one day off now and a full week off soon, leaving Hong Kong to do the heavy lifting for China trading through the holiday season.
Summary:
- The Shanghai and Shenzhen stock exchanges are closed on Friday, September 25, for the Mid-Autumn Festival, reopening Monday, September 28
- Northbound and southbound Stock Connect are closed, while Hong Kong’s exchange stays open, with its holiday falling on Saturday
- Shanghai futures have no night session Thursday and are shut Friday through Sunday
- Mainland markets trade only Monday to Wednesday next week before closing for National Day from October 1 to 7
- Trading resumes on Thursday, October 8, and exchanges stay shut on the October 10 make-up working day
- The Friday closure coincides with the final day of the Trump-Xi summit, leaving Hong Kong and the offshore yuan to lead any reaction
Mainland Chinese financial markets are closed on Friday, September 25, for the Mid-Autumn Festival, and the break is only a warm-up for a much longer shutdown in early October, when the National Day holiday will keep onshore markets closed for a full week.
The Shanghai Stock Exchange and Shenzhen Stock Exchange are both shut for cash equity trading on Friday, with regular trading resuming on Monday, September 28. Northbound and southbound Stock Connect channels linking the mainland and Hong Kong are also closed, cutting off cross-border equity flows for the day. Hong Kong Exchanges and Clearing remains open on Friday, as the city observes its Mid-Autumn public holiday on Saturday, September 26.
Onshore futures markets follow a similar pattern. According to exchange notices, the Shanghai Futures Exchange will hold no night session on Thursday evening, will be closed from Friday through Sunday, and will reopen on Monday.
The more significant disruption comes next week. Once markets reopen, mainland investors will have only three trading sessions, Monday to Wednesday, before the National Day holiday. Exchanges will be closed from Thursday, October 1, through Wednesday, October 7, with trading resuming on Thursday, October 8. Futures markets will also skip their night session on Wednesday, September 30. Saturday, October 10, is a designated make-up working day under the official holiday calendar, but exchanges will stay closed in line with their regular weekend schedule.
The timing matters for markets. Friday’s closure coincides with the final day of the Trump-Xi summit in Washington, meaning any reaction from mainland investors to its outcome will be delayed until Monday, leaving Hong Kong and offshore yuan trading to carry the initial response. The shortened trading window next week also tends to encourage position squaring before the Golden Week break, as investors weigh the risk of holding exposure through a seven-day closure while global markets continue to trade.
With two holiday interruptions in less than two weeks, liquidity in mainland assets is likely to be patchy through early October, and Hong Kong’s role as the main outlet for China-related trading will be in focus until mainland markets fully reopen on October 8.
