SEOUL, July 20 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares ended lower for a third straight session on Tuesday, as technology heavyweights tracked overnight losses on Wall Street over worries about surging coronavirus cases globally. The won weakened, while the benchmark bond yield also fell.

** The KOSPI closed down 11.34 points, or 0.35%, at 3,232.70, following a 1% decline on Monday.

** Chip giant Samsung Electronics fell as much as 0.76%, while peer SK Hynix slid 0.42%. Internet giant Naver and battery maker LG Chem also dropped 0.90% and 0.61%, respectively.

** Stocks on Wall Street fell as much as 2% on Monday, with the S&P and the Nasdaq suffering their largest single-day drop since mid-May, as a rise in worldwide coronavirus cases and increasing U.S. deaths drove investors out of risky assets.

** At home, the country reported 1,278 new cases as of Monday midnight, still in four-digit infections but lower than a record 1,615 cases marked last week.

** Foreigners were net sellers of 181.3 billion won ($157.56 million) worth of shares on the main board.

** The won ended at 1,150.4 per dollar on the onshore settlement platform, 0.23% lower than its previous close at 1,147.8, after hitting its lowest level since early October 2020 in early trade.

** In offshore trading, the won was quoted at 1,150.4 per dollar, unchanged from the previous day, while in non-deliverable forward trading its one-month contract was quoted at 1,150.3.

** In money and debt markets, September futures on three-year treasury bonds rose 0.16 point to 110.21.

** The most liquid 3-year Korean treasury bond yield fell by 5.1 basis points to 1.408%, while the benchmark 10-year yield fell by 8.0 basis points to 1.892%. ($1 = 1,150.6800 won) (Reporting by Joori Roh; Editing by Rashmi Aich)
