* KOSPI falls, foreigners net sellers

* Korean won weakens against U.S. dollar

* South Korea benchmark bond yield rises

SEOUL, April 12 (Reuters) - Round-up of South Korean financial markets:

** South Korean fell on Tuesday to their lowest level in nearly a month, as U.S. bond yields firmed ahead of inflation data, a reading that could help investors gauge the Federal Reserve's policy stance.

** The won weakened, while the benchmark bond yield rose.

** The benchmark KOSPI fell 19.25 points, or 0.71%, to 2,673.85 as of 0113 GMT, hitting the lowest intraday level since March 16.

** Technology giant Samsung Electronics fell 0.44%, while peer SK Hynix was flat. Battery maker LG Energy Solution and internet platform operator Naver dropped more than 2%.

** Foreigners were net sellers of 42.0 billion won ($33.96 million) worth of shares on the main board, extending selloffs to a fifth straight session.

** The market is in an anxious mood, with investors unsure of how much higher the U.S. bond yields would rise if consumer price index comes in higher than expected, said Cape Investment and Securities' analyst Na Jeong-hwan.

** The Bank of Korea is likely to stand pat at its meeting this week as its committee awaits the appointment of a new governor, but it will embrace a steeper rate hike path ahead to tame more than decade-high inflation, a Reuters poll showed.

** The won was quoted at 1,237.3 per dollar on the onshore settlement platform, down 0.34%.

** In offshore trading, the won was quoted at 1,236.7 per dollar, down 0.2%, while in non-deliverable forward trading, its one-month contract was at 1,236.7.

** In money and debt markets, June futures on three-year treasury bonds rose 0.08 point to 104.69.

** The most liquid 3-year Korean treasury bond yield rose by 0.1 basis point to 3.178%, while the benchmark 10-year yield rose by 6.5 basis points to 3.363%. ($1 = 1,236.9000 won) (Reporting by Jihoon Lee; editing by Uttaresh.V)
