SINGAPORE: Chicago soybean and corn futures ticked higher on Tuesday, with both markets trading near multi-month highs as dry weather in South America sparked concerns over supplies.

"We are in the weather market as far as South American crops are concerned," said one Singapore-based grains trader. "If it starts raining, prices will come down."

Corn climbed 0.1% to $6.15-1/4 per bushel and was on track for a fifth consecutive session of gains, while wheat rose 0.3% to $8.06-1/2 a bushel.Soybean and corn crop harvests are expected to be smaller in southern Brazil this season as fields are suffering from dryness, weather forecasters and consultancies said.

Global markets are being underpinned by easing worries over the pandemic.

Asian shares gained on Tuesday, cruising in the slipstream of another record-setting day on Wall Street amid strong retail figures.

A variety of asset classes from oil to Japan's Nikkei Stock Average are now trading at around one-month highs, having walked back losses from late November when the Omicron variant of COVID-19 first emerged and sent investors scurrying for safe havens.

The US Department of Agriculture on Monday said 1,577,417 tonnes of US soybeans were inspected for export last week, which was within the range of trade estimates.
