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 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.
The U.S. dollar briefly rose to its highest in more than five months against the yen and gained versus the euro after minutes of the Fed's most recent meeting showed some officials said the central bank should move to tighter conditions before year-end. The minutes also showed some believed they would have to hold to an easy monetary policy course beyond this year.
A large U.S. technology company merger helped keep stocks afloat, but indexes were dampened by profit-taking late in the session.
