（Singapore, 22.07.2026）Thousands of brokers and traders in Hong Kong could soon face longer working days as the city’s stock exchange considers extending trading hours, including scrapping the traditional lunch break and introducing an evening trading session to better align with global markets.
The proposals remain at an early stage, but they have already sparked debate across the financial industry. While supporters say longer trading hours could strengthen Hong Kong’s competitiveness as an international financial centre, many brokers question whether the potential increase in trading activity would be enough to justify the higher operating costs and additional workload.
Hong Kong Exchanges & Clearing (HKEX) has begun consulting major brokerages and trading firms on several possible changes. One proposal would move the start of equity trading forward by 30 minutes to 9 a.m. and eliminate the current one-hour lunch break. Another option under consideration would introduce an evening trading session, potentially from 8 p.m. until midnight, allowing Hong Kong investors to trade during the opening hours of US markets.
HKEX said it is committed to enhancing Hong Kong’s competitiveness and is reviewing opportunities to improve market accessibility, including trading hours. However, the exchange stressed that discussions remain exploratory and that any changes would require further consultation with regulators, market participants and Stock Connect partners.
If implemented, the reforms would represent Hong Kong’s first major extension of equity trading hours in more than a decade. The issue has long been a sensitive one. In 2011, HKEX shortened the lunch break from two hours to one and moved the morning session earlier, triggering protests by about 1,000 brokers and restaurant workers before the changes eventually took effect.
Unlike financial centres such as New York and London, which trade continuously throughout the day, several major Asian markets, including mainland China, Japan and Singapore, continue to suspend trading at lunchtime.
For many local brokers, particularly smaller firms that focus on Hong Kong and mainland Chinese stocks, the midday break serves purposes that go well beyond lunch.
Junior employees typically use the hour to reconcile morning trades, complete administrative work and prepare for the afternoon session. Senior traders and brokerage owners often schedule client lunches to discuss market developments, strengthen business relationships and identify new opportunities.
Speaking to Bloomberg, David Wong, permanent honorary chairman of the Hong Kong Securities & Futures Professionals Association, said the proposed changes would place an unnecessary burden on the industry without delivering meaningful benefits.
“The manpower and resources required are simply too great to justify the outcome,” Wong said.
Many brokers also believe longer trading hours would favour large international firms over smaller local brokerages.
Global investment banks generally have enough staff to rotate shifts throughout the trading day and already manage products such as futures that trade beyond regular cash market hours. Smaller firms, however, may struggle to maintain adequate staffing without significantly increasing operating costs.
The proposal to introduce an evening trading session has also received a mixed response.
Supporters argue that additional trading hours would give investors greater flexibility while increasing the overlap with overseas markets. David Friedland, Asia Pacific managing director at Interactive Brokers, said investor interest in after-hours trading has been growing as global investing becomes increasingly interconnected.
Others remain unconvinced. Some market participants worry that an evening session could attract more speculative trading while liquidity remains relatively thin, increasing volatility instead of improving market efficiency.
Lyndon Chao, head of equities and post-trade at the Asia Securities Industry and Financial Markets Association, warned that the growing competition among exchanges to extend trading hours may benefit only a small group of active traders rather than the broader market.
Another important question is how mainland China’s exchanges would respond if Hong Kong extends its trading day.
Mainland investors have become an increasingly important source of liquidity through the Southbound Stock Connect programme, which allows them to buy eligible Hong Kong-listed shares. Around 23% of Hong Kong’s equity market turnover in 2025 came through Southbound Stock Connect, meaning any extension of trading hours could require coordination with the Shanghai and Shenzhen stock exchanges.
Some industry participants believe there are more effective ways to strengthen Hong Kong’s competitiveness than simply keeping the market open for longer.
They argue that lowering trading costs, improving capital efficiency through cross-margining and expanding the range of derivatives available to investors would have a greater impact on trading activity.
Thomas Ip, executive director of Gaoyu Securities, told Bloomberg the proposal was a “non-essential piecemeal improvement,” arguing that broader structural reforms would do far more to enhance the market.
Hong Kong is not alone in reconsidering how long financial markets should remain open.
Around the world, exchanges are moving towards near-continuous trading as investors demand greater flexibility and competition from digital trading platforms intensifies. The London Stock Exchange recently announced plans to launch LSE 24, an overnight trading venue that will initially offer exchange-traded products before potentially expanding into equities. Similar initiatives have also been announced by the New York Stock Exchange, Nasdaq and Cboe, which are seeking to operate up to 23 hours a day during weekdays.
Elsewhere in Asia, South Korea is studying plans to extend trading hours to 12 hours a day, while Indonesia and Taiwan are also considering longer trading sessions as competition among exchanges continues to intensify.
Whether Hong Kong ultimately follows that trend remains uncertain. Many market participants believe the city’s long-term competitiveness will depend less on extending trading hours and more on reforms that lower costs, improve market efficiency and attract new investment. For many brokers, protecting the lunch break is not simply about preserving tradition, but about ensuring longer hours deliver meaningful benefits for the market rather than just a longer working day.
