South Korea's inflation rate accelerated to 2.0 percent in September, but remained below the central bank's 3.0 percent target ceiling, government data showed as calls grow for an interest rate cut.
The consumer price index rose 2.0 percent year-on-year in September, quickening from a 1.2 percent gain in August, according to Statistics Korea.
The higher rate was partly attributed to the rise in grain prices following a series of typhoons that damaged large stretches of farmland.
Core inflation, which excludes volatile energy and food prices, stood at 1.4 percent in September, up from the 1.3 percent figure posted the month before.
With inflation still comfortably below the Bank of Korea's target, the central bank is likely to come under renewed pressure to cut its key policy rate to reinvigorate a weakening economy.
Last month, the International Monetary Fund lowered its growth outlook for South Korea to 3.0 percent from a previous estimate of 3.25 percent, citing the eurozone crisis and household debt.
South Korean exports fell for the third consecutive month in September as the global economic slump hit shipments from the world's seventh largest exporter.
The slowdown had raised market expectations of an interest rate cut in mid-September, but the central bank left the rate unchanged at 3.0 percent.
