This week’s edition of The Economist is chock full of stories about the euro zone’s current sovereign debt troubles and their flagging currency, the cover story asking the same question that is no doubt on the minds of many bond traders these days.

Past financial crises show that this downward spiral can be arrested only by bold policies to regain market confidence. But Europe’s policymakers seem unable or unwilling to be bold enough. The much-ballyhooed leveraging of the euro-zone rescue fund agreed on in October is going nowhere. Euro-zone leaders have become adept at talking up grand long-term plans to safeguard their currency—more intrusive fiscal supervision, new treaties to advance political integration. But they offer almost no ideas for containing today’s conflagration.

Germany’s cautious chancellor, Angela Merkel, can be ruthlessly efficient in politics: witness the way she helped to pull the rug from under Silvio Berlusconi. A credit crunch is harder to manipulate. Along with leaders of other creditor countries, she refuses to acknowledge the extent of the markets’ panic (see article). The European Central Bank (ECB) rejects the idea of acting as a lender of last resort to embattled, but solvent, governments. The fear of creating moral hazard, under which the offer of help eases the pressure on debtor countries to embrace reform, is seemingly enough to stop all rescue plans in their tracks. Yet that only reinforces investors’ nervousness about all euro-zone bonds, even Germany’s, and makes an eventual collapse of the currency more likely.

This cannot go on for much longer. Without a dramatic change of heart by the ECB and by European leaders, the single currency could break up within weeks.

There’s also this story that, just in case you didn’t get the message from above, reiterates the point that “the risk that the currency disintegrates within weeks is alarmingly high”.
