Give credit where credit is due: Nouriel Roubini of New York University's Stern School of Business was right. On February 20 2008, I wrote a column entitled "America's economy risks the mother of all meltdowns", based on his analysis of the 12 steps to disaster. Alas, not only has the US taken those steps, but it has also - with help from others, including the UK - dragged the world behind it.

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.
