Albert Edwards, the "uber bear" of economic predictions, has warned of "global deflation and recession" in his latest notes to clients, predicting that US stocks could lose almost three-quarters of their value.
The notorious analyst for Societe Generale believes that the coming market "carnage is an indirect result of the failure of the [US] Fed's quantitative easing". He argued that investors would "reap the whirlwind" of central bank attempts to support their respective economies with looser monetary policy.
Mr Edwards has made a name for himself as an outspoken bear, frequently forecasting that the global economy and stock markets are in for a terrible time. In his latest missive he declared that recent anguish over the Chinese economy should have come as no surprise to money managers.
"The impossible trilogy of maintaining an independent domestic monetary policy and a semi-fixed exchange rate while loosening capital account restrictions is hitting home," he said. Chinese companies have prepared themselves for a further fall in the yuan, Mr Edwards claimed, putting the country in "a better position to transmit a massive deflationary shock".

Western manufacturing "will choke under this imported deflationary tourniquet", he continued. "When an economy is hurtling towards recession it is almost always the manufacturing sector that takes the less volatile services sector by the hand and leads it into a recessionary underworld."
Continuing his pessimistic analysis, Mr Edwards suggested that stocks would soon fall from their "obscene" levels. As Mr Edwards admits, "most believe a 75pc equity bear market to be impossible", yet he predicts that the S&P 500 gauge of US stocks could fall to 550, from its recent 2,100 peak. His views put him starkly at odds with the Wall Street consensus.
