SEOUL, May 13 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares jumped more than 2% on Friday, after U.S. producer prices in April rose more-than-expected, but the benchmark index posted its third weekly decline due to concerns around policy tightening and economic growth. ** The benchmark KOSPI rose 54.16 points, or 2.12%, to close at 2,604.24. For the week, it declined 1.5%

** The firm won triggered more buying from foreign investors in the afternoon, and the Nasdaq futures rising in after-hours also helped, said Lee Kyung-min, an analyst at Daishin Securities.

** South Korea's new President Yoon Suk-yeol said he was worried about slower economic growth for the year ahead, with the country logging a trade deficit and currency markets growing more volatile.

** Foreigners were net buyers of 60.5 billion won ($47.10 million) worth of shares on the main board.

** In offshore trading, the won was quoted at 1,283.7 per dollar, up 0.5% from Thursday, while in non-deliverable forward trading its one-month contract was quoted at 1,283.6.

** The KOSPI has fallen 12.54% so far this year, and lost 7.2% in the previous 30 trading sessions.
