FINANCIAL MELTDOWN: In this grave crisis, the world’s leaders are terrifyingly out of their depth.

Certain years have gone down in history as great global turning points, after which nothing was remotely the same: 1914, 1929, 1939, 1989. Now it looks horribly plausible that 2011 will join their number. The very grave financial crisis that has hung over Europe ever since the banking collapse of three years ago has taken a sinister turn, with the most dreadful and sobering consequences for those of us who live in European democracies.

The events of the past few days have been momentous: the eurozone sovereign debt crisis has escaped from the peripheries and spread to Italy and Spain; parts of the European banking system have frozen up; US Treasuries have been stripped of their AAA rating, which may be the beginning of a process that leads to the loss of the dollar’s vital status as the world’s reserve currency.

There have been warnings that we may be in for a repeat of the calamitous events of 2008. The truth, however, is that the situation is potentially much bleaker even than in those desperate days after the closure of Lehman Brothers. Back then, policy-makers had at their disposal a whole range of powerful tools to remedy the situation which are simply not available today.

Out of bullets.
