SEOUL, Aug 20 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares tumbled 3.7% on Thursday, the sharpest fall in two months, as fears of rising domestic coronavirus infections persist, while a cautious outlook from the U.S. Federal Reserve weighed on investor sentiment. The Korean won weakened, but the benchmark bond yield rose.

** The benchmark KOSPI closed down 86.32 points, or 3.66%, to 2,274.22.

** U.S. stocks ended lower on Wednesday after the minutes of Fed’s late-July meeting revealed its members are considering tweaks to monetary policy, while remaining concerned that the U.S. economy’s nascent recovery from the pandemic-induced recession faced an uncertain path.

** South Korean health officials are struggling to contain an outbreak of the new coronavirus centred in the capital city of Seoul, as new cases levelled off but remained in the triple digits on Thursday.

** Asian equities showed weaknesses as investors were disappointed at the Fed’s minutes, which failed to meet the market expectations of liquidity supply, said Lee Young-gon, analyst at Hana Financial Investment.
