South Korea's consumer prices grew at the slowest pace in four months in October due largely to state subsidies for mobile phone bills. 

The consumer price index stood at 105-point-61 last month, down one-tenth of a percent from a year earlier, according to Statistics Korea on Tuesday. It's the smallest growth since June, when the reading remained flat.

Prices of agricultural, livestock and fisheries products jumped 13-point-three percent on-year in October.

Industrial goods prices, however, dropped one percent due to low crude oil prices, while prices of gas, water and electricity slipped four percent from a year earlier.

Core inflation, which excluded volatile food and oil prices, declined point-three percent on-year in October, marking the largest monthly drop since September 1999.
