* KOSPI falls, foreigners net sellers
* Korean won weakens against dollar
* South Korea benchmark bond yield rises
SEOUL, Sept 21 (Reuters) - Round-up of South Korean financial markets:
** South Korean shares lost more than 1% on Thursday, as traders gauged the U.S. Federal Reserve's more hawkish than expected stance.
** The won weakened to a one-month low, while the benchmark bond yield climbed to a 10-month high.
** The benchmark KOSPI was down 29.54 points, or 1.15%, at 2,530.20 as of 0217 GMT, after falling as much as 1.27% to its lowest intraday level since Aug. 28.
** The Fed held interest rates steady on Wednesday but stiffened a hawkish monetary policy stance that its officials increasingly believe can succeed in lowering inflation without wrecking the economy or leading to large job losses.
** "The idea of high interest rates for longer is materialising at a faster rate than previously thought," said Seo Jung-hun, an analyst at Samsung Securities.
** In a meeting to assess domestic implications, South Korea's finance minister said authorities would take measures to stabilise markets if needed.
** South Korea's exports for the first 20 days of September rose nearly 10% from the same period a year earlier, but it was largely due to calendar effects.
** Among index heavyweights, chipmaker Samsung Electronics fell 0.72% and peer SK Hynix dropped 2.12%, while battery maker LG Energy Solution slid 1.60%.
** Of the total 935 traded issues, 142 shares advanced, while 761 declined.
** Foreigners were net sellers of shares worth 57.6 billion won ($43.01 million).
** The won was quoted 0.64% lower at 1,338.7 per dollar on the onshore settlement platform, after hitting 1,340.0, its weakest level since Aug. 23.
** The most liquid three-year Korean treasury bond yield rose by 4.5 basis points (bps) to 3.935%, while the benchmark 10-year yield rose by 5.1 bps to 4.029%, touching their highest levels since mid-November. ($1 = 1,339.2300 won) (Reporting by Jihoon Lee and Youn Ah Moon; Editing by Rashmi Aich)
