GLOBAL MARKETS-Gold, oil jump in Asia as U.S. and Iran trade threats

* Asian stock markets :

* Nikkei skids as Japan returns from holiday

* Oil prices jump on fears of supply disruptions

* Safe-haven yen, bonds and gold all in demand

SYDNEY, Jan 6 (Reuters) - Asian share markets ran into turbulence on Monday as a flare-up of tensions in the Middle East sent gold to its highest in almost seven years while oil flirted with four-month peaks.

The United States detected a heightened state of alert by Iran’s missile forces, as President Donald Trump warned the U.S. would strike back, “perhaps in a disproportionate manner,” if Iran attacked any American person or target.

Iraq’s parliament on Sunday recommended all foreign troops be ordered out of the country after the U.S. killing of a top Iranian military commander and an Iraqi militia leader.

Spot gold surged 1.2% to $1,569.47 per ounce in jittery trade and reached its highest since April 2013.

Oil prices added to their gains on fears any conflict in the region could disrupt global supplies.

Brent crude futures rose $1.02 to $69.62 a barrel, while U.S. crude climbed 81 cents to $63.86.

“The risk of further escalation has clearly gone up - given the direct attack on Iran, Iran’s threat of retaliation and Trump’s desire to look tough - posing the threat of higher oil prices,” said Shane Oliver, chief economist at AMP Capital.

“Historically though oil prices need to double to pose a severe threat to global growth and we are long way from that.”

MSCI’s broadest index of Asia-Pacific shares outside Japan was off 0.2% though China had yet to open.

Japan’s Nikkei slid 1.7% in a sour return from holiday, while E-Mini futures for the S&P 500 fell 0.4% in very choppy trade.

Sovereign bonds benefited from the safety bid with yields on 10-year Treasuries down at 1.77% having fallen 10 basis points on Friday. Treasury futures gained 7 ticks.

In currency markets, the Japanese yen remained the favoured safe harbour courtesy of Japan’s massive holdings of foreign assets. Investors assume Japanese funds would repatriate their money during a true global crisis, pushing the yen higher.

Early Monday, the dollar was flat at 108.00 yen, after touching a three-month trough of 107.78. The euro likewise eased to 120.45 yen having hit a three-week low.

The dollar was steadier against the other majors, with the euro little changed at $1.1166. Against a basket of currencies, the dollar was holding at 96.853.
