The ECB has announced that it will launch in March its first round of quantitative easing. The announcement contains some good and bad surprises: the size of the ECB's plan is gigantic, while the Central Bank was unclear about the Greek issue. How was this announcement perceived by markets?

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 recycling of current account and/or financial account surpluses through the accumulation of foreign exchange reserves by emerging countries after the 1999-2001 crisis, particularly by China, has been described as “smoking but not inhaling in international financial markets”.

The ECB has confirmed its determination to counter the risk of deflation in the eurozone by evoking the possibility of sovereign bond purchases, but is confronted once again with the heterogeneity of the area. The need for compromise could jeopardize the effectiveness of its action.

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.

Currency swaps between central banks are quickly emerging as a key feature of the international monetary system.

For a long time considered as impossible to implement, the negative interest rates on deposits of commercial banks at the central bank is now often mentioned as an option for the European Central Bank (ECB).
