A severe market crash is coming which could see stocks lose half their value, according to Mark Spitznagel, Co-Founder and Chief Investment Officer of Universa Investments, a hedge fund specialising in tail-risk hedging, which seeks to prevent losses from so called "black swan" economic events.

In a recent interview with the Wall Street Journal, Spitznagel, a long-time associate of "The Black Swan" author Nassim Nicholas Taleb, said: "I think we’re on the way to something really, really bad – but of course I’d say that," acknowledging that his warning aligns with his longstanding market outlook.

Spitznagel, whose firm has achieved significant gains during past black swan events, including the Covid-19 pandemic, believes that despite recent market downturns, including the S&P 500 experiencing its worst week since April, the recent market rally will continue for several months due to the "Goldilocks phase" of slowing inflation and anticipated rate cuts from the Federal Reserve, which could fuel further market speculation.

However, he cautioned that Fed rate cuts often precede severe market reversals.

Drawing parallels to the dot-com bust, Spitznagel believes that the forthcoming selloff could be even more devastating due to current market extremes, which he believes constitute the "greatest bubble in human history". With US debt at historic highs, he argues that the federal government will have limited capacity to respond, potentially leading to a recession by year's end.
