HONG KONG, July 21 (Reuters Breakingviews) - In one of his first public initiatives, new Hong Kong bourse boss Nicolas Aguzin might be ready to take on the weather. When asked in an interview about potential changes, he noted a longstanding requirement to close during typhoons and severe rainstorms. Aguzin also pointed out that traders had successfully managed to work from home during the pandemic. Rewriting those rules isnât easy, however; the government would have to sign off. At least it signals a willingness to try and break with an often-arcane status quo. Aguzin also could, for example, consider offering some sort of market during Hong Kongâs whopping 17-odd public holidays.
