Mainland China’s capital market will triple in size to US$100 trillion in next 10 years, Hong Kong stock exchange boss Nicolas Aguzin predicts
- A key driver of this growth will be a shift of China’s massive domestic savings towards investment in search of higher returns, says HKEX chief executive

Mainland China’s capital market, including both equities and bonds, will more than triple in size in the next decade to US$100 trillion, with Hong Kong playing a vital gateway role, according to the head of the city’s bourse operator.
If his estimate is accurate, the Chinese stock market in 10 years’ time will almost match the size of the entire US capital market today, including both stocks and bonds. That figure currently stands at US$96 trillion, according to data from the Securities Industry and Financial Markets Association.
Aguzin said a key driver of this growth will be a shift of China’s massive domestic savings towards investment in search of higher returns. China, the biggest saver in the world, had a gross savings rate of 45.7 per cent as of December 2020, he said.
A majority of these saving are now in either real estate or bank deposits, but he believes more will make its way into stocks and bonds.
“As the interest rate is staying at a low level, people will start to think of new investment opportunities and ideas,” he said.
Nineteen lenders in Hong Kong and seven in Macau are approved to sell products under the new cross-border scheme.
