Korea Exchange Chairman Jeong Eun-bo is visiting the United States to sign a memorandum of understanding with the New York Stock Exchange covering market operations and infrastructure. The exchanges will share experience on extending trading hours and adopting T+1 settlement, and may establish a joint consultative body for follow-up discussions. Korea Exchange plans to open an after-market session next month and build a 24-hour trading system by the end of next year. Jeong will host a September 3 New York roadshow with Bank of America Securities for about 20 institutional investors, presenting South Korean capital-market reforms and seeking feedback on foreign-investor access. He will also visit Silicon Valley to meet technology companies and examine trends including artificial intelligence.
