SEOUL, June 9 (Reuters) - Round-up of South Korean financial markets:
** South Korean shares closed lower on Wednesday, dragged by tech heavyweights and a sell-off by foreigners, with sentiment dented by investors avoiding big bets ahead of U.S. inflation data and European Central Bank policy meeting this week.
** The won weakened and the benchmark bond yield fell.
** The benchmark KOSPI ended 31.65 points, or 0.97%, lower at 3,216.18, marking the third decline in five sessions.
** Among heavyweights, technology giant Samsung Electronics fell 0.98% and peer SK Hynix dropped 3.92%. Battery maker LG Chem and internet giant Naver also slid 0.74% and 1.10%, respectively.
** Foreigners were net sellers of 329.5 billion won ($295.67 million) worth of shares on the main board.
** “Investors are seen taking a wait-and-see stance ahead of the U.S. inflation data release ... Outflow of foreign investors widened in afternoon trade, pulling KOSPI further down,” said Lee Kyoung-min, analyst at Daishin Securities.
** The won ended at 1,115.4 per dollar on the onshore settlement platform, down 0.11%.
** In offshore trading, the won was quoted at 1,115.1 per dollar, up 0.2%, while in non-deliverable forward trading, its one-month contract was quoted at 1,114.8.
** In money and debt markets, June futures on three-year treasury bonds rose 0.09 point to 110.99, while the 3-month Certificate of Deposit rate was quoted at 0.66% in late-afternoon trade.
