SEOUL, Sept 28 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares closed lower on Tuesday, in line with broader Asian markets on lingering fears over the fate of China Evergrande Group and worries about the potential impact of a widening power shortage in China. The won weakened to a one-year low, while the benchmark bond yield rose.

** The KOSPI closed down 35.72 points, or 1.14%, at 3,097.92.

** Chip giants led the decline on the benchmark index, with Samsung Electronics and SK Hynix falling 1.80% and 0.96%, respectively. Naver and Kakao dropped 2.61% and 2.08%, respectively.

** Without making a reference to ailing developer Evergrande , China's central bank vowed to protect consumers exposed to the housing market on Monday and injected more cash into the banking system.

** Widening power shortages in China, meanwhile, halted production at a number of factories including suppliers to Apple Inc and Tesla Inc and are expected to hit the country's manufacturing sector and associated supply chains.

** Further denting risk appetite were soaring U.S. Treasury yields that touched a three-month high overnight following the Federal Reserve's signals last week that bond purchases could be tapered as early as November.

** Foreigners were net buyers of 10.7 billion won ($9.07 million) worth of shares on the main board.

** The won ended at 1,184.4 per dollar on the onshore settlement platform, 0.64% lower than its previous close and marking the lowest close since mid-September last year.

** In offshore trading, the won was quoted at 1,184.2 per dollar, down 0.5% from the previous day, while in non-deliverable forward trading its one-month contract was quoted at 1,185.1.

** In money and debt markets, December futures on three-year treasury bonds fell 0.16 point to 109.35.

** The benchmark 10-year yield soared by 8.2 basis points to 2.249%. (Reporting by Joori Roh; Editing by Subhranshu Sahu)
