NEW YORK, April 5 (Reuters) - Prices of spot gold notched a record high on Tuesday as a downgrade of Portugal's debt stirred a bid for safety, while Brent crude ended above $122 a barrel, at a 2-1/2 year high.
The rise in oil prices on unrest in oil-exporting countries overshadowed another interest rate hike from China and fed inflation fears, which supported gold prices. Spot gold <XAU=> rose to a record high above $1,450 an ounce.
"What it shows is that big money continues to believe gold will go higher ... because Bernanke wants to grow at any cost," said Axel Merk, portfolio manager of the $600 million Merk Mutual Funds, referring to Federal Reserve Chairman Ben Bernanke's comments late on Monday suggesting he was committed to completing a $600 billion stimulus program as scheduled in June.
"The other reason for gold to go up is that there was a downgrade in Portugal, so people realize there are still some issues," Merk added.
Corn futures also hit a record high, extending their biggest rally in six months as traders feared supplies could run out unless ranchers or ethanol makers cut back on purchases.
Corn futures <Cc1> on the Chicago Board of Trade set a new high of $7.70-3/4 per bushel after matching 2008's record high on Monday. Corn has surged more than 15 percent in four days since a U.S. government report showed unexpectedly low inventories as of March 1. [
