Portugal Colonial - Asian stocks rise on Trump U-turn but unease sees oil bounce

Equity markets in New York jumped and crude plunged Monday after the US president made the surprise announcement that he would hold off fresh attacks on energy infrastructure for five days following negotiations with an unidentified "top person".

The news ramped up hopes for an end to the conflict and the reopening of the Strait of Hormuz, through which a fifth of oil and gas flows.

Brent slumped as much as 14 percent at one point to $96, while all three main indexes on Wall Street climbed more than one percent, with commentators suggesting prices could drop to as low as $90.

However, the mood was deflated somewhat after Iranian media said there had been no talks between Tehran and Washington.

And the Fars news agency reported that Deputy Speaker of Parliament Ali Nikzad said there would be no talks, while the Strait of Hormuz would remain effectively closed.

Asian markets enjoyed a positive start, with Tokyo, Hong Kong, Shanghai, Sydney, Seoul, Taipei and Manila all up, though the gains were pared as the morning wore on. Singapore and Wellington both fell.

Crude bounced, with both main contracts up more than three percent as investors remain sceptical about the chances of a breakthrough in talks.

And the dollar climbed against the euro, pound and yen after sinking on Monday.

Markets had started the week deep in the red after Trump warned Saturday that Iran had 48 hours to allow traffic through Hormuz or he would strike the country's energy infrastructure. Tehran replied by saying the waterway "will be completely closed" should he act on his threat.

His decision to U-turn hours before the deadline came up was pounced on by observers as another example of a TACO moment -- an acronym of "Trump Always Chickens Out" -- in which he escalates before pulling back from the brink.

But Stephen Innes at SPI Asset Management warned the president may have overplayed his hand.

"You can talk down a market. You can jawbone crude lower. You can release emergency reserves and tweak sanctions to flood the tape with supply optics," he wrote.

"But you cannot instantly repair disrupted shipping lanes, fractured refining capacity, or the insurance black hole forming around tanker traffic. The market may trade the headline in the short term, but it settles on the barrel in the medium term. And right now the barrel is still constrained."

Meanwhile, the Wall Street Journal reported that Saudi Arabia and the United Arab Emirates were considering joining the fight following persistent and damaging attacks from Iran since the US-Israel strikes began on February 28.

The article said they were not deploying troops but pressure was building on them to do so as Tehran looks to exert greater sway over the region.

Elsewhere, the European Union and Australia struck a long-awaited free trade deal on Tuesday as they completed years of negotiations to boost exports in the face of global uncertainty over trade.

They also signed an agreement to step up defence cooperation as well as critical raw materials.
