Hong Kong Exchanges and Clearing (HKEX) is considering extending its trading hours to align with global competitors and reinforce the city's position as an international financial centre.
The move comes as pressure mounts on the Asian market to modernise its infrastructure in the face of aggressive expansions by Western exchanges.
Nasdaq recently launched a 23-hour trading day, while the London Stock Exchange has pushed for round-the-clock access.
These developments have intensified scrutiny on Hong Kong's comparatively shorter trading window, prompting the bourse operator to evaluate structural changes that could improve liquidity and attract international capital.
The potential shift in trading hours complements broader efforts by Hong Kong authorities to overhaul listing rules and introduce new financial products.
City officials have previously signalled a comprehensive strategy to accelerate the renovation of market frameworks, aiming to sustain the hub's competitiveness against rising global alternatives.
