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

** South Korean shares ended higher on Friday as upbeat U.S. retail sales data boosted sentiment, though investors refrained from placing big bets ahead of the country's three-day holiday. The won weakened, while the benchmark bond yield rose.

** The KOSPI closed up 10.42 points, or 0.33%, at 3,140.51, after logging a 0.74% decline in the previous session.

** It gained 0.47% on a weekly basis, following a 2.35% fall clocked in the previous week.

** Chip giants Samsung Electronics and SK Hynix led gains on the benchmark, adding 1.45% and 2.88%, respectively, while web portal operator Naver inched up 0.25%.

** Meanwhile, shares in Hyundai Heavy Industries leapt 85% from their initial public offering price in Friday's trading debut.

** Foreigners were net buyers of 45.8 billion won ($38.94 million) worth of shares on the main board.

** U.S. retail sales unexpectedly increased in August, which could temper expectations for a sharp slowdown in economic growth in the third quarter.

** Investors now await the U.S. Federal Reserve's upcoming policy meeting for more clues on the tapering of its bond-buying programmes.

** South Korea's financial markets will be closed from Monday to Wednesday due to the Korean thanksgiving Chuseok holiday.

** The won ended at 1,175.0 per dollar on the onshore settlement platform, 0.27% lower than its previous close at 1,171.8.

** In offshore trading, the won was quoted at 1,176.0 per dollar, down 0.1% from the previous day, while in non-deliverable forward trading, its one-month contract was quoted at 1,176.4.

** In money and debt markets, September futures on three-year treasury bonds fell 0.04 points to 110.14.

** The benchmark 10-year yield rose by 2.7 basis points to 2.070%. ($1 = 1,176.0200 won) (Reporting by Joori Roh; Editing by Devika Syamnath)
