SINGAPORE, Feb 16 (Reuters) - Chicago wheat futures hit a one-week high on Tuesday as arctic temperatures in key U.S. growing areas raised worries about global supplies.
Soybeans rose for a third consecutive session while corn bounced back.
The most-active wheat contract on the Chicago Board of Trade rose 2.4% to $6.52-1/4 a bushel as of 0202 GMT, after hitting its highest since Feb. 9 at $6.57 a bushel earlier in the session.
Soybeans gained 1.4% at $13.90-1/2 a bushel and corn added 1.4% to $5.46-1/2 a bushel.
Commodity Weather Group last week estimated that 10% of the U.S. soft wheat crop and 15% of the hard wheat crop were at risk of damage from winterkill caused by freezing temperatures.
Offering more support to agricultural commodities, global shares looked to extend their bull run to a 12th consecutive session on the back of optimism about an economic recovery.
The U.S. Department of Agriculture on Friday said private exporters reported the sale of 195,338 tonnes of corn to Costa Rica and 115,577 tonnes of corn to Guatemala. (Reporting by Naveen Thukral; Editing by Devika Syamnath)
