HKEX Explores Extending Trading Hours, Midday Break May Be Abolished
nashnova research
Hong Kong Exchanges and Clearing is consulting market participants on extending trading hours, with scrapping the daily one-hour lunch break as the central question; this means → Hong Kong is being forced to respond to competitive moves by Nasdaq and the Korea Exchange, but whether the change would actually lift liquidity remains unproven.
What exactly is HKEX discussing?
The Financial Times reports that HKEX is in early-stage consultations with market participants on extending trading hours, focused on eliminating the noon-to-1 p.m. lunch break.
HKEX CEO Bonnie Chan posted on LinkedIn about "plans to optimize the trading session." SFC CEO Julia Leung said this month that regulators are "studying measures including extending securities trading hours."
No formal consultation paper has been issued. This means → what is happening now is a trial balloon, not a decision — implementation is still far off.
Why is this coming up now?
Nasdaq plans to launch up to 23 hours of daily trading as early as December — Hong Kong fears Asian-hours order flow migrating to the U.S.
The Korea Exchange added an after-hours session from 4 p.m. to 8 p.m. last month, directly extending its trading window.
In plain terms = competitors are all staying open longer. If Hong Kong doesn't follow, it risks losing business.
Do other Asian exchanges still take a lunch break?
Tokyo breaks from 11:30 a.m. to 12:30 p.m.; Shanghai and Shenzhen break for a full 90 minutes — Hong Kong is not Asia's only exchange with a midday pause.
But the London Stock Exchange dropped its lunch break in 1950. All major U.S. and European markets trade continuously.
This means → if HKEX becomes the first major Asian exchange to scrap lunch, its hours will fall out of sync with Shanghai and Shenzhen — a differentiation opportunity, but also a source of cross-market friction.
What does the industry think — for or against?
In favor: David Tsang, head of investment banking at Alliance Capital Partners, calls the lunch break "an antiquated practice" and argues Hong Kong must sharpen its edge against U.S. exchanges.
Barclays' head of Asia macro strategy, Mitul Kotecha, says dropping the break would "help improve liquidity because more people would be at their desks" — but adds the real-world impact may not be "huge."
A trader at a large Hong Kong financial institution put it bluntly: "The lunch break is already dead in practice. The nature of the market has made a long lunch somewhat redundant."
What is the real question here?
HKEX's lunch break was once two hours long, then cut to 90 minutes, then compressed to one hour in 2012. Scrapping it would end the tradition entirely.
Some traders still prefer to keep it. This reflects a deeper worry: longer hours ≠ more liquidity — opening for one more hour does not guarantee one more dollar of turnover.
In plain terms = extending operating hours is the easy part. Whether it actually attracts more trading volume is what the market still needs to prove.
