Warren Buffett is once again the second-richest person on the planet, and he has President-elect Donald Trump to thank.
Buffett added US$5.8 billion to his fortune this week, leading gains for the world's wealthiest as he leaped over Spain's Amancio Ortega and Amazon.com founder Jeff Bezos to reclaim the No. 2 spot on the Bloomberg Billionaires Index.
Buffett, who supported Democrat Hillary Clinton in the election and ferried voters to the polls in his Nebraska hometown, benefited as shares in Wells Fargo & Co soared 13 per cent in the two days after the November 8 election on speculation that a Republican administration would bring less regulation and sideline some of the industry's sharpest critics.
His Berkshire Hathaway holds a 10 per cent stake in the San Francisco-based lender.
The world's richest added US$15 billion to their fortunes this week at the close of trading on Thursday in New York, according to the Bloomberg index.
