The South Korean economy barely grew last quarter as political chaos weighed on consumer spending, according to a Reuters poll of economists who expect the Bank of Korea to cut interest rates next month following a surprise hold last week. Asia's fourth-largest economy grappled with uncertainty from President Yoon Suk Yeol's brief Dec. 3 martial law attempt, weakening economic sentiment and sluggish domestic demand which overshadowed the recovery in exports. After only growing 0.1% in the July-September quarter, South Korea's economy likely expanded a seasonally adjusted 0.2% in Q4, according to the median forecast of 24 economists.
