A SUMMARY of trading in key commodities markets overseas: Oil prices rose amid renewed concerns about the oil-rich Middle East ahead of US President Barack Obama's visit to Israel next week and a fall in a key US consumer confidence reading. New York's main contract, West Texas Intermediate for April, closed at $93.45 a barrel, up 42 cents from Thursday. Brent North Sea crude for delivery in May climbed 86 cents to settle at $109.82 a barrel in London trade. Obama's upcoming visit to Israel next week, expected to highlight tensions over Iran's suspected nuclear weapons program, was putting the market on edge, said James Williams of WTRG Economics. An unexpected increase in consumer prices lured traders to gold and other metals on Friday, lifting their prices. Gold for April delivery rose $US1.90, or 0.1 per cent, to settle at $US1,592.60 an ounce. Silver for May rose 4.4 cents, or 0.2 per cent, to $US28.85 per ounce. A measure of US consumer prices rose 0.7 per cent in February, the biggest one-month increase in more than three years, the Labor Department said. But it was mainly a result of a nine percent surge in gas prices. Traders turn to gold and other metals on signs of inflation, because they expect them to keep pace with rising prices. Other metals were mostly higher. Platinum group metals rose, and copper dipped. Platinum for April delivery rose $US2.60, or 0.2 per cent, to $US1,592.40 an ounce. Palladium for June delivery rose $US4.90, or 0.6 per cent, to $US775.65 an ounce. Contracts for May copper slipped 1.6 cents, or 0.5 per cent, to $US3.5205 per pound.
