Hong Kong and mainland China stocks finish year with world-leading gains
City’s benchmark Hang Seng Index ends 2025 up 28 per cent, while the CSI 300 Index of mainland stocks rises 18 per cent

The Hang Seng Index finished the year with a 28 per cent increase as 2025 trading ended at noon on Wednesday – securing the 89-member benchmark its best yearly performance since gaining 36 per cent in 2017. The CSI 300 Index of the mainland’s yuan-denominated stocks climbed 18 per cent, the biggest gain since 2020.
Hong Kong’s market will reopen for trading on Friday, and China’s markets will be shut for the rest of the week.
The resilience of China’s growth also helped buoy sentiment. The mainland economy expanded by 5.2 per cent in the first three quarters of the year as exports defied the trade strife with the US and emerged as a bright spot. That put the annual growth target of around 5 per cent within reach. China’s yuan appreciated to its strongest level against the US dollar in two and a half years this week.
