SEOUL, Dec 6 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares ended higher for a fourth straight session on Monday, as foreign buying of chip shares offset the hit from worries around the Omicron coronavirus variant. Both the won and the benchmark bond yield fell.

** The KOSPI closed up 4.92 points, or 0.17%, at 2,973.25, with investors refraining from making big bets ahead of key U.S. inflation data.

** Chip giants Samsung Electronics and SK Hynix gained 0.93% and 0.42%, respectively, while Samsung SDI added 0.87%.

** On the main board, foreigners were net buyers of 58.2 billion won ($49.22 million) worth of shares.

** As Omicron emerged in more countries, South Korea, which has confirmed 24 cases of the variant so far, imposed stricter measures to contain the outbreak.

** Meanwhile, U.S. jobs data suggested an earlier-than-expected tapering by the Federal Reserve when they meet later this month, with the focus now shifting to the consumer price report due on Friday.

** The won ended at 1,183.0 per dollar on the onshore settlement platform, 0.25% lower than its previous close.

** In offshore trading, the won was quoted at 1,182.5 per dollar, down 0.2% from the previous day, while in non-deliverable forward trading, its one-month contract was quoted at 1,182.8.

** In money and debt markets, December futures on three-year treasury bonds rose 0.09 point to 108.95.

** The most liquid 3-year Korean treasury bond yield fell by 3.1 basis points to 1.870%, while the benchmark 10-year yield fell by 1.5 basis points to 2.218%. ($1 = 1,182.5100 won) (Reporting by Joori Roh; Editing by Devika Syamnath)
