South Korea's benchmark Kospi fell 23.06 points, or 0.33%, to 7,057.86 in the first minutes of trading on Monday, Sept. 28, despite gains on Wall Street. The decline came as hopes for a diplomatic breakthrough in the Iran conflict pushed oil prices lower. U.S. stocks ended higher on Friday, led by technology and industrial companies, with the Dow Jones Industrial Average up 0.93%, the S&P 500 up 0.51% and the Nasdaq Composite up 0.48%. Brent crude settled at around $104 a barrel after reports that Iran had proposed a plan to end the conflict. The Kospi had extended its winning streak to four sessions on Wednesday before South Korean markets closed Thursday and Friday for the Chuseok holiday.
