The South Korean won fell to the lowest level in a month on Monday as better-than-expected U.S. jobs data spurred speculation the Federal Reserve would accelerate its move toward raising interest rates.

The local currency closed at 1,112.1 per dollar, down 13.4 won from the previous session's end, after falling to as low as 1,112.60 won at one point.

The closing price marks the lowest since 1,117.70 won on Dec. 8, 2014.

Beating the market median forecast, data by the Labor Department showed on Friday that the U.S. added 295,000 jobs in February. The data also showed that the unemployment rate sank to 5.5 percent during that month, down from 5.7 percent in January, the lowest since May 2008.

The data stoked expectations that the Fed would start raising borrowing costs in June, sooner than what market players have projected.

"Upbeat data regarding the job market boosted the dollar, but intervention concerns would limit the won's fall," said Jun Seung-ji, an analyst at Samsung Futures Co.

Foreign investors also turned to a net-selling position on Monday, snapping their 10th consecutive buying streak, further putting downward pressure on the local currency.

The country's key stock index, the KOSPI, fell back on Monday from its five-month high to close at 1,992.82, down 20.12 points or 1 percent from the previous session's close.

Meanwhile, the won-yen cross rate stood at 918.81 as of 3 p.m. (Yonhap)
