Can Super Mario save the euro? Mario Draghi said last Thursday that the European Central Bank’s job is to stop sovereign bond yields rising if these increases are caused by fears of a euro break-up. While this represents a sea-change in the ECB president’s thinking, it risks sowing dissension within his ranks. He will struggle to come up with the right tools to achieve his goals.
Draghi seemingly stared into the abyss and had a fright. Spanish 10-year bond yields shot up to 7.6 percent on July 24 while Italian ones rose to 6.6 percent. The high borrowing costs are not simply a reflection of the two countries’ high debts and struggling economies. Investors also fear “convertibility risk” – or the possibility that the euro will break up and they will get repaid in devalued pesetas and liras.
The central banker’s statement that dealing with convertibility risk is part of the ECB’s mandate is therefore highly significant. He rammed home his message, saying: “Within our mandate, the ECB is ready to do whatever it takes to preserve the euro. And believe me, it will be enough.”
Markets responded swiftly. Spain’s borrowing costs fell to 6.8 percent, while Italy’s dropped just below six percent. But these yields have to drop below five percent – and stay there – before confidence in the euro project will return. What’s more, it’s unclear what Draghi will actually do.
One possibility, immediately latched onto by investors, is that the ECB will relaunch its programme of buying government bonds in the market. But such an operation would be tough to calibrate. If the ECB was prepared to do whatever it took to drive yields below a certain level, the pressure would certainly be off Spain and Italy. But politicians might then stop reforming their economies. When the ECB bought Italian bonds last summer, that’s precisely what happened.
