Ireland is forecast to borrow over 11bn euros and more this year. Like almost every developed and developing nation, it is in deficit. where is all the borrowed money coming from? The very smart Martin Wolf has the answer:

The world has run out of willing and creditworthy private borrowers. The spectacular collapse of the western financial system is a symptom of this big fact. In the short run, governments will replace private sectors as borrowers. But that cannot last for ever. In the long run, the global economy will have to rebalance. If the surplus countries do not expand domestic demand relative to potential output, the open world economy may even break down. As in the 1930s, this is now a real danger

To understand this, one must understand how the world economy has worked over the past decade. A central role has been played by the emergence of gigantic savings surpluses around the world. In 2008, according to forecasts from the International Monetary Fund, the aggregate excess of savings over investment in surplus countries will be just over $2,000bn (see chart).

The oil exporters are expected to generate $813bn. Remarkably, a number of oil-importing countries are also expected to generate huge surpluses. Foremost among them are China ($399bn), Germany ($279bn) and Japan ($194bn). As a share of gross domestic product, China’s current account surplus is forecast at an astonishing 9.5 per cent, Germany’s at 7.3 per cent and Japan’s at 4 per cent. In aggregate, the oil exporters, plus these three countries, are forecast to generate 83 per cent of all surpluses.
