SEOUL, March 17 (Reuters) - Round-up of South Korean financial markets:

** South Korean stocks closed lower on Wednesday, following a sell-off in Wall Street overnight, as most investors kept to the sidelines ahead of the outcome of the U.S. Federal Reserve’s policy meeting. The won ended nearly unchanged, while the benchmark bond yield rose.

** The benchmark KOSPI ended down 19.67 points, or 0.64%, at 3,047.50, reversing a 0.71% gain on Tuesday. It dropped over 1% in early trade, tracking declines in the S&P 500 and Dow Jones overnight as yields on longer-maturity U.S. Treasury bonds ticked up.

** “(Investors’) eyes are all-in on FOMC. The decline (in KOSPI) narrowed from early trade, but uncertainties are still high,” said Kiwoom Securities’ analyst Seo Sang-young.

** The U.S. central bank’s Federal Open Market Committee (FOMC) will end a two-day meeting later in the day.

** Foreigners were net sellers of 526.2 billion won ($465.72 million) worth of shares on the main board.
