The warning was issued by Deloitte’s Chief Economist Debo De during Abta’s annual Travel Matters conference in Westminster.
In a presentation examining the current global economic challenges, De noted: "US stocks are now about as overvalued as they were at the peak of the dot-com boom, and well above levels of overvaluation that we saw on the eve of the great crash of 1929."
"This will also mean there'll be greater investor pressure and scrutiny on tech businesses and on how they're monetising AI. So if you're running pilots in your own businesses, and you've got specific cost assumptions, you should probably account for significant rises to those in the coming years."
