* KOSPI falls, foreigners net sellers
* Korean won weakens against dollar
* South Korea benchmark bond yield rises
SEOUL, Sept 6 (Reuters) - Round-up of South Korean financial markets:
** South Korean shares fell on Wednesday as a jump in global oil prices stoked concerns about inflation, souring appetite for risk assets. The won weakened, while the benchmark bond yield rose.
** The benchmark KOSPI fell 11.92 points, or 0.46%, to 2,570.26 by 0209 GMT.
** Saudi Arabia and Russia said on Tuesday they would extend their voluntary oil supply cuts to the end of the year, sending oil prices to the highest since late 2022.
** "Oil prices are the most important variable," said Choi Yoo-june, an analyst at Shinhan Securities. "Once faster inflation is triggered, monetary tightening will only continue for longer."
** Among index heavyweights, chipmaker Samsung Electronics fell 1.13% and peer SK Hynix lost 0.84%, while battery maker LG Energy Solution slid 0.19%.
