Much of the gains for the ultra-rich come down to a surge in US stocks, underscoring bets that Trump, on his return to the White House, will implement an agenda favouring lower taxes and less regulation. The S&P 500 jumped 2.5% in the best post-election performance in history, while the US dollar also gained.

The rich are already adding to their wealth after Donald Trump’s election. According to Bloomberg’s Billionaire Index, the world’s 10 richest people got even richer on Wednesday, collectively adding $64 billion to their coffers on the day Trump captured the presidency for the second time.
