The national security law in Hong Kong won't affect the operation of its financial markets and the legal activities of any financial institutions or personnel in the region, said Paul Chan, financial secretary of the Hong Kong Special Administrative Region (HKSAR), in a blog on Monday.

Hong Kong's Securities and Futures Commission also assured that the regulating principals and methods, used by analysts in terms of the sources of information and data they use and the manner in which their views and opinions are expressed in their reports, and trading behaviors such as hedging and shorting would remain unchanged.

Since the national security law was officially implemented on June 30, the global market has been watching the potential uncertainties the law could bring to Hong Kong's financial markets.

Paul said that considering it's a newly-enacted important law, it's understandable that the market needs time to adapt and some financial institutions have questions on its applications.

What the financial institutions need to know is, Paul stressed: "As a global financial center, Hong Kong's success is based on a good rule of law, free flow of information and capital, freedom of speech and publication, the national security law protects those values, so it can ensure Hong Kong's long-term prosperity."

The national security law only targets actions and activities that will severely jeopardize national security, it won't affect the regular financial activities by institutions and individuals, Paul said.
