SEOUL (Reuters) -The vice chief of South Korea's financial regulatory agency said on Monday there is a high likelihood of the country's stock market being included in a key developed market index in the near future. "We see a very high possibility of being included soon, if not this time," Kim So-young, vice chairman of the Financial Services Commission, said at a press conference held in Seoul for foreign media. The stock market of Asia's fourth-largest economy is currently categorised as an emerging market by global index provider Morgan Stanley Capital International (MSCI), despite many other metrics indicating its developed-economy status.
