George Soros and Peter Bofinger present a measured approach for the intervention of the European Central Bank in eurozone bond markets, essentially envisioning it as a temporary liquidity provider of last resort. However, the ECB is already playing this role to a large extent. It has along with the eurozone bail-outs bought European politicians 18 months in which to devise the fiscal rules and growth strategy the authors call for. Unfortunately, leaders have repeatedly failed to reach any semblance of consensus on a lasting solution to the crisis.

Therefore, the exit strategy envisioned here for the ECB is dubious. Without a clear mechanism for winding down the ECB bond purchases, it becomes impossible to imagine a situation where the ECB could end its bond buying programme without causing huge market distortions.

The authors approvingly cite the example of the unlimited liquidity provision given to banks. However, this could equally be used as an illustration of the risks mentioned above. Although the ECB’s unlimited liquidity provision for the banking sector may have avoided a bank run, it simultaneously created a set of so-called ‘zombie banks’. Precisely because of the absence of an exit strategy, these banks have now become reliant on ECB liquidity to survive, while stripping them of the incentive to reform the bad practices and mismanagement which got them into this situation in the first place. The cost of this is now becoming clearer, with some banks on the precipice of failure, forcing a widespread recapitalisation of the banking sector – of which some cost will undoubtedly fall onto taxpayers. Against this backdrop, it becomes a huge risk for the ECB to stake its independence and credibility on the hope that such a solution will be achieved in the near term.
