SHANGHAI, Jan 8 (Reuters) - Asian shares tumbled on Wednesday, while oil, safe-haven Treasury prices and gold shot higher after Iran fired rockets at U.S.-led forces in Iraq, stoking fears of a wider conflict in the Middle East.
European equity markets were expected to open lower, with pan-region Euro Stoxx 50 futures STXEc1 down 0.77%, German DAX futures FDXc1 off 0.91% and FTSE futures FFIc1 0.45% lower.
Iran's missile attacks on the Ain Al-Asad air base and another in Erbil, Iraq, early in the day came hours after the funeral of an Iranian commander whose killing in a U.S. drone strike has intensified tensions in the region. reports of the attacks sparked a sudden rise in risk aversion on worries over how the United States would respond. Asian equities later trimmed losses, Japan's yen stabilised and U.S. bonds tempered their rally as investors paused for breath after U.S. President Donald Trump said in a tweet that "All is well!", and "So far, so good!". are getting exaggerated moves but that's of course volatility playing. Markets simply hate uncertainty. It's an old adage but it definitely holds true in the current situation - markets can price risks but they can't price uncertainty," said James McGlew, executive director of corporate stockbroking at Argonaut in Perth.
In his tweet late Tuesday, Trump said that an assessment of casualties and damage from the strikes was under way and that he would make a statement on Wednesday morning. A U.S. official said the United States was not aware of any casualties from the strikes. broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was down 0.72%, having dropped more than 1% earlier in the day. China's blue-chip CSI300 index .CSI300 was 1.18% lower.
Japan's Nikkei .N225 dipped 1.57%, paring earlier losses of more than 2%, while Australian shares .AXJO clawed back from a more-than-1% drop to shed 0.13%. U.S. S&P500 e-mini stock futures ESc1 , which had earlier tumbled nearly 1.7%, were down 0.38%.
Rob Carnell, Asia-Pacific chief economist at ING in Singapore, said possible further escalation of tensions between Iran and the United States could still provoke a prolonged negative market reaction.
"If you see U.S. treasuries rallying a bit this morning, expect them to rally quite a bit further should there be a forceful response from the United States, which I'd imagine there would be...from a market perspective I think this one could run and run," he said.
The yield on benchmark 10-year U.S. Treasury notes US10YT=RR last stood at 1.7742%, down from a U.S. close of 1.825% on Tuesday, but up from session lows. U.S. 10-year Treasury futures TYc1 had earlier peaked at their highest level since November, and were last up 0.29%.
The two-year yield US2YT=RR fell to 1.5061% compared with a U.S. close of 1.546%.
The yen, which had hit its strongest point against the greenback since October in morning trade, gave up most of its gains later in the day. The U.S. currency was last down 0.11% against the yen at 108.30 JPY= .
The euro EUR= was 0.03% weaker, buying $1.1147 and the dollar index .DXY , which measures the greenback against six major peers, was 0.06% lower at 96.949.
In commodity markets, global benchmark Brent crude futures LCOc1 shot back above $70 per dollar to their highest level since mid-September in the initial hours after Iran's strikes.
They were last up 1.08% at $69.01 per barrel, while U.S. crude CLc1 added 0.96% to $63.30 a barrel.
"I don't think many investors try and anticipate global politics, especially when it involves Trump ... they are probably more inclined to price things in as they come," said Hasan Tevfik, senior research analyst at MST Marquee.
Gold also fell below a key psychological level as initial fears eased. The precious metal was 1.30% higher on the spot market XAU= at $1,594.33 per ounce, having earlier blasted through $1,600. GOL/

Analysts say the escalating Middle East tensions are likely to keep markets on edge.
"If it does look like we've got U.S. casualties, then I don't think Trump is going to just stand back and take that," said Matt Simpson, a senior market analyst at Gain Capital in Singapore.
"World War III has been thrown around. I don't think we're there yet. But it does look like Iraq II."
