[SEOUL] The South Korean won slipped to a one-week low early on Thursday, pressured by a broadly strong US dollar after oil prices jumped on Opec's agreement to its first output cuts since 2008.
The local currency trimmed some losses after data showed activity in China's manufacturing sector expanded more than expected in November and South Korean exports rose for the first time in three months in November.
The won was quoted at 1,175.2 against the US dollar as of 0200 GMT, down 0.5 per cent from Wednesday's close of 1,169.1. It was trading near lows seen last Friday.
With the US dollar's "breather" from a rally coming to an end, "the won may slump to 1,180 today," said Jung Sung Yoon, a foreign exchange analyst at Hyundai Futures.
The US dollar and regional stocks rose after the Organization of the Petroleum Exporting Countries on Wednesday agreed to its first output cut since 2008, aiming to reduce 1.2 million barrels per day (bpd), or over 3 per cent, from January.
