Is it working? To an extent, say economists. "A provisional verdict ... is that the Draghi bazooka has succeeded in stabilising bank balance sheets but has yet to lay the monetary foundation for an economic recovery," judges Simon Ward at Henderson Global Investors.
Under Mr Draghi's leadership, the ECB has also played a crucial role in the deal to secure a second Greek bailout, as the central bank agreed to forego profits it had made on its Greek government bond holdings. Instead, it would return them to the eurozone member states to pass back to Athens.
