Amid concern in financial markets that the debt crisis could break apart the euro zone,
European Central Bank 
President Jean-Claude Trichet warned of contagion dangers and called for more action by euro-zone governments to pool fiscal governance.
"We are now experiencing extreme tensions," Mr. Trichet said in an interview with Germany's Der Spiegel magazine. The ECB provided a transcript Saturday.
"In the market, there is always a danger of contagion—like the contagion we saw among the private institutions in 2008." Mr. Trichet said. Contagion can flare up quickly, he said, even in "half a day."
Financial markets sensed that danger over the past week, when the recent euro selling turned into a rout, despite the composition the previous weekend of a nearly $1 trillion safety net for problem governments. For many, the response to the Greek debt crisis didn't address longer-term concerns that the euro zone might have become unmanageable in its current form.
What's needed now, Mr. Trichet said, is "a quantum leap" in how Europe manages its fiscal economy, which he says in the most difficult situation since
World War II
.
"There needs to be major improvements to prevent bad behavior, to ensure effective implementation of the recommendations made by peers and to insure real and effective sanctions in case of breaches," he said.
Having thrown money at the problem and failed, the euro zone is coming to see centralized fiscal oversight as the only means of convincing investors that the Greek debt crisis won't recur. So far, nothing else seems to have convinced investors that the euro is durable.
Early proposals suggest the first steps to a kind of federal government that the euro's critics have said was needed from the inception of the currency project.
German Chancellor Angela Merkel 
has warned that the survival of the euro and even the European Union itself is at stake, adding calls for stricter fiscal governance that doesn't allow weaker countries to determine standards.
