When euro zone governments agreed last year to give the European Central Bank the power to supervise its banks, that looked like another victory for its president Mario Draghi. It is more like a poisoned chalice.
The ECB will certainly get a chunk of extra power. But it will also be blamed when banks run into trouble, as they inevitably will. Draghi himself is experiencing this first hand following the scandal at Monte dei Paschi di Siena (MPS), which has had to be rescued by the Italian state. He has been lambasted for failing to supervise the country’s third largest bank properly when he ran the Bank of Italy – although the criticism seems overdone and has often been fuelled by his political opponents back in Rome.
