SEOUL (Reuters) - The South Korean won’s volatility has been greater than other Asian currencies of late and authorities are watching the situation very closely, a foreign exchange official told Reuters on Thursday.

The official’s comment comes a day after the won extended gains to reach its highest in more than a year on Wednesday and reiterated finance ministry officials’ remarks that the government is ready to take action in case of excessive market movements.
