BlackRock’s chief executive Larry Fink has written to shareholders in the $6.8tn asset manager to offer reassurance that the global economy will recover from the coronavirus pandemic — and that some early investment opportunities are already starting to emerge.

Fink, who has written to BlackRock investors in his capacity as chair of the US asset manager, told shareholders that the Covid-19 crisis, which has claimed the lives of more than 35,000 globally, would lead to a shift in the psychology of investors and businesses.
