  • J.P. Morgan's top quant, Marko Kolanovic, predicts a "Great Liquidity Crisis" will hit financial markets, marked by flash crashes in stock prices and social unrest.
  • The trillion-dollar shift to passive investments, computerized trading strategies and electronic trading desks will exacerbate sudden, severe stock drops, Kolanovic said.

Sudden, severe stock sell-offs sparked by lightning-fast machines. Unprecedented actions by central banks to shore up asset prices. Social unrest not seen in the U.S. in half a century.

That's how J.P. Morgan Chase's head quant, Marko Kolanovic, envisions the next financial crisis. The forces that have transformed markets in the last decade, namely the rise of computerized trading and passive investing, are setting up conditions for potentially violent moves once the current bull market ends, according to a report from Kolanovic sent to the bank's clients on Tuesday. His note is part of a 168-page mega-report, written for the 10th anniversary of the 2008 financial crisis, with perspectives from 48 of the bank's analysts and economists.

Kolanovic, a 43-year-old analyst with a Ph.D. in theoretical physics, has risen in prominence for explaining, and occasionally predicting, how the new, algorithm-dominated stock market will behave. The current bull rally, the longest in modern history by some measures, has been characterized by extended periods of calm punctuated with spasms of selling known as flash crashes. Recent examples include a nearly 1,600 point intraday drop in February and a 1,100 point decline in August 2015.

"They are very rapid, sharp declines in asset values with sharp increases in market volatility," Kolanovic, the bank's global head of macro quantitative and derivatives research, said in a recent interview. But those flash crashes occurred during a backdrop of a U.S. economic expansion; the new market hasn't been tested in the throes of a recession, he said.
