In a more recent note, Professor Roubini predicts a combination of stagnation and deflation*. In doing so he points, with some glee, to the most recent analysis of the global outlook from JPMorgan Chase, once among the most bullish of analysts. Now, under the rubric “A bad week in hell”, JPMorgan states that: “Once again, we have taken an axe to near-term growth forecasts for the developed world and will likely follow up with additional downward revisions for emerging economies in the coming weeks. Already, our forecasts suggest that global gross domestic product will contract at a near 1 per cent annual rate” in the fourth quarter of 2008 and the first quarter of 2009.

JPMorgan expects shrinkage this quarter at an annualised rate of 4 per cent in the US, 3 per cent in the UK and 2 per cent in the eurozone. It is forecasting 0.4 per cent global growth in 2009, with advanced countries shrinking 0.5 per cent and emerging ones growing 4.2 per cent.

Given the near-disintegration of the western world's banking system, the flight to safe assets, the tightening of credit to the real economy, collapsing equity prices, turmoil on currency markets, continued steep declines in house prices, rapid withdrawal of funds from hedge funds and ongoing collapse of the so-called “shadow banking system”, these forecasts even look quite optimistic. The outcome next year could be far worse.
