The Trump trade has become a rollercoaster for equity investors
The US dollar fell and was poised for its worst week in more than a year while world stock markets edged up yesterday amid some calm following declines earlier in the week spurred by uncertainty relating to Donald Trump's US presidency.
On Wall Street, key stock indexes climbed, led by energy shares. The S&P energy index was up 1.1pc along with a jump in oil prices.
The US dollar slipped 0.7pc yesterday and was down about 2pc for the week, its worst week since April 2016. Besides worries surrounding Trump, the US currency has suffered from a resurgent euro, which has gained more than 2pc this week.
"The dollar overall, across the board, has been getting beat up this week and a lot of that has to do with the political risk here in DC," said John Doyle, director of markets at Tempus Inc in Washington. "While we saw a little bit of a reprieve yesterday, we're right back on that dollar weakness train."
In Dublin the Iseq was up 0.91pc to 6,930.76. Aryzta was a big mover, surging more than 5pc at one stage, and closing 4.1pc up on the day in the wake of Kevin Toland's appointment as CEO.
Elsewhere, US politics remains the big story.
Leading world equity markets scaled record highs on Monday, then plunged in one of the sharpest cross-asset routs in years amid uproar over Donald Trump's firing of FBI director James Comey.
Markets fear the political damage could hamper Trump's promised fiscal stimulus - which has spurred markets higher since November.
On Friday, the Dow Jones Industrial Average was up 115.62 points, or 0.56pc, the S&P 500 gained 17.23 points, or 0.73pc and the Nasdaq rose 0.71pc.
Emerging markets meanwhile have been rocked by an unfolding corruption scandal in Brazil that could engulf President Michel Temer.
