A senior director at Standard and Poor's ratings services said on Tuesday that low interest rates are not imperative for the long-term, sustainable growth that the agency looks for when assessing sovereign ratings.

“Low interest rates have never been the reason for long-term sustained growth we are interested in,” said S&P's KimEng Tan, senior director in the Asia-Pacific region in a media roundtable in Seoul.

Tan refrained from specifically commenting on South Korea's policy rate, which currently stands at a record-low 1.50 per cent.
