South Korea benchmark bond yield rises

SEOUL, Nov 21 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares began the week lower due to renewed worries about COVID-19 outbreaks in China, while weak exports data also weighed on investors' sentiment. The Korean won weakened, while the benchmark bond yield rose.

** The benchmark KOSPI fell 23.28 points, or 0.95%, to 2,421.20 as of 0105 GMT.

** Fresh outbreaks of COVID-19 were seen across major Chinese cities of Beijing and Guangzhou, stoking concerns of lockdown measures weighing on the economy.

** "The local market was weighed by Chinese authorities' expressions of concern over a surge in COVID-19 infections, overshadowing some U.S. Federal Reserve officials' dovish comments that could have provided support," said Seo Sang-young, an analyst at Mirae Asset Securities.

** Meanwhile, South Korea's exports for the first 20 days of November dropped 16.7% from the same period a year ago, dragged down by weak demand for chips and from China, with the trade balance set for an eighth straight monthly deficit.

** Technology giant Samsung Electronics fell 0.97%, peer SK Hynix dropped 2.38%, and battery maker LG Energy Solution declined 2.51%.

** Most other heavyweights, such as automakers and online platform operators, also fell more than 1%. Of the total traded issues of 924, the number of advancing shares was 205.

** Foreigners were net sellers of shares worth 143.7 billion won ($106.56 million) on the main board.

** The won was quoted at 1,346.6 per dollar on the onshore settlement platform, down 0.47%.

** In money and debt markets, December futures on three-year treasury bonds fell 0.11 point to 103.22.

** The most liquid three-year Korean treasury bond yield rose by 1.7 basis points to 3.823%, while the benchmark 10-year yield rose by 2.6 basis points to 3.837%. ($1 = 1,348.5400 won) (Reporting by Jihoon Lee; editing by Uttaresh.V)
