Portugal Colonial - Oil jumps on Trump's Iran threat; gold retreats from highs

"With the Middle East tinder box looking set to ignite again, oil prices have moved sharply higher, lifting shares in listed energy giants," said Susannah Streeter, chief investment strategist at Wealth Club.

Stock markets mostly rose in Asia and Europe as investors also pored over company earnings and the US Federal Reserve's latest policy update.

Trump meanwhile warned that Tehran must negotiate a deal over its nuclear programme, which the West believes is aimed at making an atomic bomb.

"The next attack will be far worse! Don't make that happen again," he added, referring to US strikes against Iranian targets in June.

International benchmark Brent crude oil topped $70 a barrel Thursday for the first time since September with a gain of five percent. Prices later eased, showing gains of more than three percent.

"Strikes on Iran would risk causing oil prices to jump and threaten to boost inflation in much of the world, reducing the pace or number of interest rate cuts by major central banks," said Jason Tuvey, an emerging markets economist at research group Capital Economics, in a note.

- Gold falls back -

Gold tumbled back after hitting a new record at $5,595.47 an ounce as investors rushed to assets deemed safe, including silver, which reached its own record of $120.44 an ounce.

The dollar steadied after losing ground most of this week.

Gold declined more than five percent and silver plunged more than eight percent, while copper and nickel prices also fell, as traders reassessed the market.

"The parabolic rally had to come to an end," as commodity prices had "gone up too far, too quickly", Kathleen Brooks, research director at XTB trading group, told AFP.

Demand for the precious metals is also being spurred by worries about the weakening dollar, sparked by speculation that Trump is happy to see the world's reserve currency weaken despite the potential risk of pushing up US inflation.

An uneventful policy announcement by the Fed on Wednesday did little to inspire buying, though observers said traders were optimistic that US interest rates will come down as Trump prepares to name his pick as the next governor of the central bank.

On stock markets, Meta rocketed by 10 percent at the opening after the US parent of Facebook and Instagram published quarterly earnings that topped expectations, as revenue grew along with huge investments in artificial intelligence.

Microsoft, whose earnings disappointed analysts, tumbled more than 10 percent on concern for the return on investment for the software giant's spending on AI.
