Another corn purchase by South Korea’s largest feedmaker Nonghyup Feed Inc (NOFI) on Thursday brought a surge of Korean corn buying in the past week to just over 1 million tonnes. NOFI purchased around 137,000 tonnes of corn to be sourced from optional origins in an international tender that closed on June 07, while South Korea’s Feed Leaders Committee bought about 65,000 tonnes in a separate deal. Falling corn prices have generated a wave of purchasing by South Korean importers in the last week. Deals totalling 330,000 tonnes were reported on Tuesday, while Korean importers late last week also bought 522,000 tonnes. Corn prices are traditionally very volatile in the current time of the year, when weather changes can impact the US crop. It looks like importers are using the current low price level to get some supply cover bought. Chicago corn futures hit a two-month low as favourable weather in the US Midwest grain belt improved crop prospects and pushed the July and December contracts below technical support levels.
