The Economist has a free special report 'on the turmoil in the world's financial markets': Heading for the rocks (hat tip Mike)

The tremors in financial markets have gone far beyond their beginnings in the US subprime mortgage sector, and indeed far beyond the borders of the US. The full impact on the markets, and the repercussions on the global economy, remain unclear, but we can sketch out three broad scenarios:

• Scenario 1. The Economist Intelligence Unit’s central forecast, to which we attach a probability of 60%, sees the impact being contained by timely monetary policy action, with only a modest effect on the global economy.

• Scenario 2. Our main risk scenario, with a 30% probability, envisages the US falling into recession, with substantial fallout in the rest of the world.

• Scenario 3. Should the US enter recession, another, darker scenario arises: that corrective action fails, and severe economic repercussions cascade from the US into the world economy with devastating effect. We attach only a 10% probability to this outcome, but the potential impact is so severe that it warrants careful consideration.

Since scenario 1 informs our regular output and Scenario 3 has a low probability, the bulk of the report focuses on scenario 2.

The full special report is here.
