Trump has ignited business confidence in US - JPMorgan boss Dimon

The election of Donald Trump as the president of the US has been a major boost to businesses in the country, according to the head of one of its biggest banks.

JPMorgan Chase chief executive Jamie Dimon told Bloomberg on Thursday that the President has "woken up the animal spirits" of the US economy, with the three major stock indices hitting record highs in the weeks and months following his victory.

Shares in the New York-based investment bank have gained almost 30% since Trump emerged victorious over Hillary Clinton in November 2016, with several other Wall Street giants romping to huge gains.

"It seems like he's woken up the animal spirits," Dimon said.

There was speculation that Dimon was being lined up to lead the Treasury department as part of Trump's administration, but the post was eventually filled by former Goldman Sachs chief executive Stevemn Mnuchin.

Dimon urged American citizens to "look at the policy, forget the tweets" in reference to the former reality television star's fondness of 147-character rants on social media throughout his campaign and short time in the Oval Office.

He added that he was confident that Trump's policies would be positive for growth in the long run, particularly his pledge to overhaul the US tax system in favour of businesses.

"If he gets it done, even part of it, it will be good for growth, good for jobs, good for Americans," Dimon added. "I'm really confident he will get that done."
