SEOUL, Jan 26 (Reuters) - Round-up of South Korean financial markets: ** South Korean stocks fell on Tuesday as foreign investors turned net sellers due to liquidity fears after China’s central bank withdrew cash from its banking system and as uncertainty over a U.S. stimulus package lingered. ** The Korean won and the benchmark bond yield both fell. ** By 0630 GMT, the benchmark KOSPI fell 68.68 points, or 2.14%, to 3,140.31.

** Short-term borrowing costs in China jumped to their pre-COVID-19 levels on Tuesday, pressured by the combination of the central bank’s extended net drain of cash from the financial system and higher holiday demand. ** Worries over the $1.9 trillion U.S. stimulus plan rose after it faced opposition from Republicans in Congress.

** That overshadowed data showing South Korea grew at a faster-than-expected pace in the fourth quarter.

** Foreigners were net sellers of 1,976.0 billion won worth of shares on the main board. Retail investors net purchased more than 4 trillion worth of shares. ** Heavyweight chip giants Samsung Electronics and SK Hynix dropped 3.02% and 4.44%, respectively. ** The won was quoted at 1,106.5 per dollar on the onshore settlement platform, 0.52% lower than its previous close of 1,100.7. ** In offshore trading, the won was quoted at 1,106.8 per dollar, down 0.4% from the previous day, while in non-deliverable forward trading its one-month contract was quoted at 1,106.6. ** MSCI’s broadest index of Asia-Pacific shares outside Japan rose 1.33%. ** The KOSPI has risen 9.29% this year and gained 16.5% in the previous 30 trading sessions. ** The trading volume during the session in the KOSPI index was 859.77 million shares. Of the total traded issues of 910, the number of advancing shares was 237. ** The won has lost 1.8% against the dollar this year.
