Billionaires have seen their fortunes hit record highs during the pandemic, with top executives from technology and industry earning the most. The world's richest saw their wealth climb 27.5% to $10.2trn (7.9trn) from April to July this year, according to a report from Swiss bank UBS. That was up from the previous peak of $8.9trn at the end of 2017 and largely due to rising global share prices. UBS said billionaires had done extremely well" in the Covid crisis. It also said the number of billionaires had hit a new high of 2,189, up from 2,158 in 2017. It comes as a World Bank report on Wednesday showed extreme poverty is set to rise this year for the first time in more than two decades due to the pandemic. Among the billionaires, the biggest winners this year have been industrialists, whose wealth rose a staggering 44% in the three months to July. "Industrials benefited disproportionately as markets priced in a significant economic recovery [after lockdowns around the world]," UBS said. Tech billionaires have also had a good pandemic, seeing their wealth soar 41%. UBS said this was "due to the corona-induced demand for their goods and services" and social distancing accelerating "digital businesses [and] compressing several years' evolution into a few months". Healthcare billionaires also benefited as the crisis put drug makers and medical device companies in the spotlight.
