South Korea's consumer sentiment fell for the first time in six months in September amid concerns over an export slowdown following the United States' new tariff scheme, the central bank said Wednesday. The composite consumer sentiment index stood at 110.1 this month, down 1.3 points from August, according to a survey conducted by the Bank of Korea. The index had climbed for five straight months through August, reaching its highest level since January 2018, on the back of solid exports and optimism over the government's supplementary budget. A reading above 100 indicates that optimists outnumber pessimists, while a figure below 100 means the opposite. Bilateral talks are under way to set details of the agreement, with no formal agreement having yet been finalized.
