SEOUL, Aug 3 (Reuters) - South Korea"s consumer inflation accelerated in July, staying at a nine-year peak marked in May, as hot weather conditions lifted prices of fresh food, while oil products and housing rental and other services costs continued rising.

That was also same as a 2.6% rise in May when it marked the fastest pace since April 2012, and continued to stay above the central bank"s 2% target for a fourth straight month.

The cost of agricultural, livestock and fisheries and petroleum products jumped 9.6% and 2.8%, respectively, while that of housing rentals and dining rose 1.4% and 2.5% each. Inflation will likely slow going forward, economists say, due to an impact from toughened COVID-19 distancing measures and the fading base effect of oil and commodity prices. "Korea"s social-distancing measures due to the new wave of the virus pose downside risks to CPI ... which will likely affect services sector CPI," said Park Chong-hoon, economist at Standard Chartered Bank Korea, adding that he sees inflation easing below 2% in September. The country struggles to contain the highly contagious Delta variant, even as it stepped up social distancing measures to the toughest level for the Seoul metropolitan and neighbouring areas. read more Core CPI, which excluded volatile energy and food prices, came at 1.2% year-on year, unchanged from June.
