"The won rose against the dollar in March due to increased exports and inflows of foreign capital into local stock markets," the BOK said in a monthly report on international finance.

Meanwhile, the South Korean currency posted 6.1 won in daily value changes against the dollar in March, down from 6.8 won a month earlier, it said.

The won finished the month at 1,118.40 against the greenback, compared to 1,130.7 a month earlier.

Foreign investors poured a net $5.49 billion into the local financial markets -- $3.15 billion in stocks and $2.34 billion in bonds -- in March, the BOK said. It was an increase from $4.93 billion in net inflows a month earlier.

The credit default swaps premium for foreign exchange stabilization bonds came to 48 basis points in March, up from 46 basis points a month earlier, the BOK said. (Yonhap)
