Timing is everything. If you're looking at the Hong Kong Stock Exchange holidays 2025 list, you’ll notice something immediately. It’s messy. Unlike the predictable rhythm of the New York Stock Exchange, where things mostly stay shut on Mondays, Hong Kong plays by a mix of lunar cycles and colonial-era legacies. You can't just guess when the Hang Seng (HSI) is going to take a breather. If you miss a settlement date because you assumed the market was open on a random Tuesday in October, that’s on you.
The HKEX isn't just a local shop. It’s the gateway to China. When the mainland markets (Shanghai and Shenzhen) close for Golden Week but Hong Kong stays open for part of it, the "Southbound" and "Northbound" trading links through the Stock Connect get weird. Liquidity dries up. Volatility spikes. It’s basically a minefield for the unprepared.
The Lunar New Year Gap
The biggest disruption in the Hong Kong Stock Exchange holidays 2025 cycle hits early. January. While Western traders are just getting over their New Year’s Day hangovers (the market is closed Wednesday, January 1st, obviously), the real break happens later in the month. The Year of the Snake starts on January 29th.
The exchange shuts down starting Wednesday, January 29th, and stays dark through Friday, January 31st. That is a massive three-day trading void right in the middle of the week. Honestly, if you’re holding leveraged positions over this break, you better hope there’s no massive policy shift from the People’s Bank of China while the doors are locked. You've got no way to exit. Markets reopen on Monday, February 3rd. By then, the world might look completely different.
When the Weekend Steals Your Holiday
Hong Kong has this specific rule about holidays falling on Sundays. If a public holiday hits a Sunday, the following Monday becomes a general holiday. It’s great for office workers. For traders? It’s another day of zero volume.

Take Ching Ming Festival. In 2025, it falls on Saturday, April 5th. Because it's a Saturday, and Saturday isn't a trading day anyway, you don't get a "makeup" day. But then look at Easter. Good Friday is April 18th. Easter Monday is April 21st. The HKEX stays closed for both. That’s a four-day weekend including the Saturday and Sunday.
Then comes May. Labor Day is Thursday, May 1st. Closed. The Birthday of the Buddha is Monday, May 5th. Closed again. You’re basically only trading three days that first week of May. If you're a day trader, this is a nightmare for momentum. If you’re a long-term investor, it’s just noise. But for the person trying to hedge a portfolio against US Federal Reserve announcements, these gaps are dangerous.
The Mid-Autumn and National Day Collision
This is where it gets confusing. The Day Following the Chinese Mid-Autumn Festival is Monday, October 7th. But wait. National Day is Wednesday, October 1st.
Let's look at the actual Hong Kong Stock Exchange holidays 2025 schedule for October:
- Wednesday, October 1: National Day (Closed)
- Monday, October 6: Day following the Mid-Autumn Festival (Closed)
- Wednesday, October 29: Chung Yeung Festival (Closed)
October is essentially a Swiss cheese month for the HKEX. You have these one-day "on-again, off-again" trading sessions. It’s incredibly easy to lose track of which day the Connect is open. Usually, the Northbound trading (HK investors buying A-shares) closes a day or two earlier than the actual holiday to allow for currency settlement. If you don't account for the $T+2$ settlement cycle, your cash will be trapped in the system longer than you planned.
Why the "Stock Connect" Matters More Than the Holiday
You can't just look at the HKEX calendar in a vacuum. You have to look at the mainland. The Shanghai Stock Exchange often takes a full week off for "Golden Week" in October. Hong Kong doesn't.
This creates a "disconnect" in the Stock Connect. Even if the Hong Kong Stock Exchange holidays 2025 list says the market is open, you might not be able to trade certain mainland-linked stocks if the clearing house in Shanghai is closed.
Basically, liquidity becomes a ghost. You see a price on the screen, but when you try to hit the bid, the spread is wider than a canyon because the primary market for the underlying asset is asleep. Real pros know that the days between holidays in Hong Kong are often more treacherous than the holidays themselves.
The Full 2025 HKEX Holiday Breakdown
Don't skim this.
The first half of the year is heavy on breaks. New Year’s Day starts it off on January 1st. Then the Lunar New Year stretch from January 29 to 31. Good Friday on April 18 and Easter Monday on April 21 follow. Then the May Day / Buddha’s Birthday double-tap on May 1 and May 5. Tuen Ng Festival (Dragon Boat) falls on Saturday, May 31, so no extra day off there.
The second half is a bit more spread out. HKSAR Establishment Day is Tuesday, July 1. Then we hit the October madness: National Day on Oct 1, Mid-Autumn break on Oct 6, and Chung Yeung on Oct 29. Finally, the year wraps with Christmas Day (Thursday, Dec 25) and the first weekday after Christmas (Friday, Dec 26).
If you're counting, that's a lot of dark screens.
Actionable Steps for the 2025 Trading Year
Stop relying on your memory. If you are active in the Hong Kong market, you need to bake these dates into your risk management software now.
Check your margin requirements. Brokers often hike margin requirements before long breaks like the Lunar New Year. They don't want to be left holding the bag if the market gaps down 5% on Monday morning. If you're close to your limit, a three-day holiday could trigger a forced liquidation before the market even opens.
Watch the $T+2$ rule. If you sell a stock on the Tuesday before the Lunar New Year break, don't expect that cash to be in your bank account by Thursday. The settlement days only count when the banks and the exchange are open. In 2025, that three-day January break effectively pushes your liquidity back by nearly a full week.
Mind the currency conversion. If you're trading in USD but the HKEX is closed, the HKD/USD peg doesn't stop moving, but your ability to hedge your equity exposure does.
Final thought: Hong Kong is unique because it's where the East's lunar calendar smashes into the West's Gregorian calendar. 2025 is particularly choppy. Mark your calendars, double-check your settlement dates, and for heaven's sake, don't try to trade the day before Golden Week starts unless you enjoy watching your spreads disappear into thin air.
- Verify all specific "Northbound" and "Southbound" trading calendars on the HKEX official site at least 48 hours before any major Chinese holiday.
- Adjust automated trading bots to account for the lack of liquidity during the "bridge" days between October 1st and October 6th.
- Ensure your brokerage account has sufficient "cushion" for the January 29-31 gap to avoid volatility-induced margin calls.
