[SEOUL] The South Korean won skidded to a 2-year low against the dollar on Tuesday morning, as Greece's deal with is creditors allowed markets to refocus their attention on the greenback which is being bolstered by expectations of higher interest rates later this year.
The won was down 0.7 per cent at 1,138.0 per dollar as of 0233 GMT after falling as low as 1,140.7, the lowest level since July 10, 2013.
"The Greece issue is no longer in the spotlight and investors are now looking at US markets as the Fed chief is expected to keep her stance that interest rates will be raised within the year," said Jeon Seung-ji, a foreign-exchange analyst at Samsung Futures.
Market participants are keeping an eye on Federal Reserve Chair Janet Yellen's semi-annual testimony on monetary policy later in the week which is largely expected to mirror her news conference last Friday.
Mr Jeon added the won is expected to trade within 1,135 and 1,142 on Tuesday.
