Jamie Dimon, the boss of JPMorgan, has reportedly been approached to become Donald Trump’s Treasury Secretary, even though the Wall Street heavyweight would be considered by most to be an outsider for role because he has repeatedly insisted he would not want the job.

A member of the US president-elect’s team contacted Mr Dimon, who is well-respected in the banking industry, about the job, Reuters said.

Reports that Mr Trump’s advisers were considering the banking boss for the role were dismissed by a source close to the bank, who told The Telegraph that there was a “less than 1pc” chance of Mr Dimon becoming Treasury Secretary.

Meanwhile, former congressional aide Jeb Hensarling was also reported to be considered as a candidate for Treasury Secretary. Mr Hensarling is chairman of the House Financial Services Committee and has pursued top Republican priorities, such as rolling back the 2010 Dodd Frank law.

Billionaire-turned-reality-television-star Mr Trump has no government experience and faces the challenge of reassuring investors by filling his administration with respected individuals.

The tycoon stunned the world when he confounded pollsters to beat Hillary Clinton to the White House.

A JPMorgan spokesman declined to comment on the Reuters report. It is not known how Mr Dimon responded to the Trump team’s request, the news agency said.
