Money supply in South Korea grew at a slower pace in September from a month earlier, the central bank said Thursday.

    The nation's "M2" totaled 2,383 trillion won about (US$2.07 trillion) for September, up 6.9% from a year earlier, according to the Bank of Korea (BOK). It marks a 0.3% rise from August, according to South Korea's (Yonhap) News Agency.

    M2 is a measure of money supply counting the currency in circulation, including bank debentures and deposits with a maturity of less than two years, along with stock investments. It's a key economic indicator closely monitored by the authorities.

    The on-year money supply growth rate stood at 8.3% in February before falling to 6.7% in May. In August, it stood at 7.2%.
