The International Monetary Fund is putting a bit of a damper on recovery optimism. Olivier Blanchard, director of the IMF's research department, warns that the turnaround will not be simple because the financial crisis has left deep scars which will affect both supply and demand for many years to come. And doesn't the forklift sector know that first hand? Blanchard's message is that we shouldn't underestimate the challenges ahead. "Sustaining the ... recovery is likely to require delicate rebalancing acts, both within and across countries. An understanding of the issues and the dangers, and some co-ordination across countries, is likely to be as crucial during the next few years as it was during the most intense part of the crisis," he says.
