US, Mexico deal sends Wall Street soaring

The United States and Mexico announced a breakthrough deal on trade on Monday, sparking a Wall Street rally that pushed major indices to fresh record closes.

Canada's dollar and Mexico's peso both strengthened against the US dollar, which in turn weakened against a basket of other currencies.

In Europe, trading was thin with London closed for a public holiday.

US president Donald Trump and outgoing Mexican president Enrique Pena Nieto hailed the new trade agreement, which raises hopes the North American Free Trade Agreement can be salvaged after Canada rejoins the talks on Tuesday.

The deal tightens local content requirements for autos, as well as updating provisions on labor rights, e-commerce and financial services, among other things.

"It's a big day for trade. It's a really good deal for both countries," president Donald Trump said in announcing the agreement from the Oval Office, with Mexico's president Enrique Pena Nieto participating by telephone.

In New York, the benchmark Dow Jones Industrial Average pushed past the 26,000 mark for the first time since January, closing up one per cent.

The broad-based S&P 500 and Nasdaq both finished at records, with the Nasdaq closing above 8,000 points for the first time.

Maris Ogg of Tower Bridge Associates told AFP that markets were banking on a successful outcome with Canada.

"Hopefully that will be the case but you just don't know," she said.

"Once you start to sweep some of the uncertainties away, the market feels a little more confident. That is what is happening."

The United States and Mexico had been holding bilateral talks for the past five weeks on updating the 1994 trade pact, while Canada had taken a pause from the negotiations.
