Europe and Asia face hard landings as bubbles burst
I am bullish on Asia but let's not get ahead of ourselves. The US is a $9.5 trillion (£4.9 trillion) consumption economy: China is $1 trillion, and India is $650bn. They are not yet at the stage where they can fill the void left by an over-indebted US," he said.
Mr Roach said US consumption reached 72pc of GDP in 2007. "
No country in the history of the world has ever consumed that much of its GDP.

A return to normal levels of savings would amount an economic shock equal to 5pc of GDP.
