The ECB will purchase a monthly €60bn of private and public debt instruments between March 2015 and September 2016 – a total worth over €1 trillion. While the timing and size of purchases are known, there is more leeway than it seems in the way purchases are allocated to each category of assets.

Instead of buying sovereign debt, the ECB could broaden further its purchases to include equity of all sorts. Fuelling an equity bubble is no worse than fuelling a bond one. It can be mitigated by intervening secretly and including non listed securities. Inhibitions to take risk should be lifted.

The long awaited Juncker Plan for investment in Europe has arrived a few weeks ago. Beyond the creation of a Strategic Fund, the Plan as a whole has disappointed: not adamant enough to eliminate the deep obstacles to cross-border investment, and opaque in generating the “List” of projects to be financed. Yet, even imperfectly, Europe has now done its homework.

European policymakers are currently busy addressing two issues: moribund investment and banks on extended sick leave. Some observers might be tempted to segregate these issues. While investment would be in the remit of States, the financial health of our economies would be under the responsibility of the ECB alone.

Some five years after the severe recession of 2009, private sector investment in Europe is still dangerously sluggish. And public investment has been cut further, reinforcing a long term downward trend. At a mere 2% of GDP, it has halved over thirty years.

The decline in investment rates in the euro area following the global financial crisis has been sharp. And it looks as though it will not reverse significantly. Rebooting investment and channeling investable funds to the right places on the continent is therefore a major challenge for policy makers.

For a fact, measures of headline consumer price inflation have decelerated sharply over the recent past. At 0.8-1%; inflation hovers around levels that are clearly below the ECB’s flagship 2% medium-term objective.

Strikingly, the debate about the Feb 7 ruling of the German Constitutional Court against the ECB’s flagship OMT programme has gone almost unnoticed in France. This is wrong. The French should care about it.
