SEOUL, Sept 27 (Reuters) - Round-up of South Korean financial markets:

** South Korean stocks rose on Monday as foreign investors bought local shares for an eighth straight session, although a ban by China on crypto trading weighed on the market. The Korean won weakened slightly, while the benchmark bond yield rose.

** The benchmark KOSPI rose 8.40 points, or 0.27%, to 3,133.64 by 0632 GMT.

** Among heavyweights, technology giant Samsung Electronics rose 0.52% and peer SK Hynix climbed 0.48%, while LG Chem advanced 1.18% and Naver fell 0.62%.

** Foreign buying drove the KOSPI index higher but a decline in Chinese stock markets capped the gains, said Kim Seok-hwan, an analyst at Mirae Asset Securities.

** China's most powerful regulators on Friday intensified a crackdown on cryptocurrencies with a blanket ban on all crypto transactions and mining, hitting bitcoin and other major coins and pressuring crypto and blockchain-related stocks.

** Foreigners were net buyers of 337.2 billion won worth of South Korean shares on the main board.

** Shares of Shinwon Corp, a South Korean apparel maker with a presence in the Kaesong industrial zone in North Korea, closed up 16.2% as hopes for inter-Korean cooperation rose over the weekend.

** The won was quoted at 1,176.8 per dollar on the onshore settlement platform, 0.03% lower than its previous close at 1,176.5.

** In offshore trading, the won was quoted at 1,176.9 per dollar, up 0.2% from the previous day, while in non-deliverable forward trading its one-month contract was quoted at 1,177.1.

** The KOSPI has risen 9.05% so far this year, but lost 4.1% in the previous 30 trading sessions.

** The most liquid 3-year Korean treasury bond yield fell by 0.8 basis point to 1.566%, while the benchmark 10-year yield rose by 1.8 basis points to 2.169%. (Reporting by Cynthia Kim; Additional reporting by Jihoon Lee; Editing by Subhranshu Sahu)
