* KOSPI falls, foreigners net sellers
* Korean won weakens against U.S. dollar
* South Korea benchmark bond yield rises
SEOUL, Feb 26 (Reuters) – Round-up of South Korean financial markets:
** South Korean shares tumbled on Friday, reversing almost all gains clocked in the previous session, as a tech rout on Wall Street and a steep rise in U.S. Treasury yields weighed. The won weakened, while the benchmark bond yield rose.
** The benchmark KOSPI fell 85.74 points, or 2.77%, to 3,013.95 by 0143 GMT, after jumping 3.50% in the previous session.
** A drop in technology shares sank Wall Street overnight, while the U.S. Treasury yields vaulted to their highest since the pandemic began on expectations of a strong economic expansion and related inflation.
** Most heavyweights slid, with technology giants Samsung Electronics and peer SK Hynix slumping 3.63% and 4.38%, respectively, while Naver and LG Chem fell 2.35%-4.83%.
** Meanwhile, South Korea’s exports likely grew for a fourth straight month in February, a Reuters poll showed, thanks to improving global trade, hopes of a vaccine-led recovery and demand for semiconductors and cars. Full-month data is due on March 1.
** The Bank of Korea plans to make outright purchases of treasury bonds worth around 5 to 7 trillion won ($4.5-$6.3 billion) during the first half of the year, a day after it kept
the benchmark interest rate steady.
** Foreigners were net sellers of 857.0 billion won ($764.34 million) worth of shares on the main board.
** The won was quoted at 1,120.9 per dollar on the onshore settlement platform, down 1.17%.
** In offshore trading, the won was quoted at 1,119.5, while in non-deliverable forward trading its one-month contract was quoted at 1,119.4.
** The most liquid 3-year Korean treasury bond yield rose by 2.8 basis points to 1.022%, while the benchmark 10-year yield rose by 7.8 basis points to 1.959%.
