Larry Fink, BlackRock's chief executive, said investors were too quick to conclude that high inflation was over, raising the prospect that bond yields would rise in the future as prices rose. "The biggest risk facing the world today is that the whole world thinks inflation is over," Mr. Fink told Bloomberg on the sidelines of the World Economic Forum in Davos, Switzerland, on Wednesday, adding that his views were at odds with those expressed by market forces. "I really think we're going to have high inflation." Referring to investments in artificial intelligence, Mr. Fink said that building data centres would require a lot of private sector funding. BlackRock is working with Microsoft and others to raise a $30 billion fund, and Mr. Fink said the private market needed to pay particular attention to how data centres were powered. " In the short term, let's be clear that it will be powered primarily by natural gas, which in the US is natural gas, "said Mr. Fink, adding that electricity demand should spark discussions about the future role of nuclear power.
