Italy Pushes Euro to Fore, the Last Place Europe Wants It

Through more than two months of tough negotiations to form a government in Italy after inconclusive March elections, global financial markets remained relatively calm. Italy’s uncertainties seemed contained to Italy, and Europe’s economy kept growing.

That changed this week when Italy’s president, Sergio Mattarella, effectively blocked two populist parties from forming a government. He judged that a crucial member of their proposed cabinet was intent on having Italy abandon the euro, though they had not explicitly campaigned on that issue.

In doing so, Mr. Mattarella may have laid the groundwork for a new election, one that amounts to a referendum on the euro. The European Union and financial markets reacted with dread. On Tuesday, the Dow plunged almost 400 points, the value of the euro plummeted and the cost of borrowing for Italy shot up.

For the European Union, another Italian election would be terrifically bad timing.
