I would like to recall again that, in the euro area, banks are the main channel for mobilizing domestic savings and financing investment. This explains why ECB’s non-standard measures have primarily aimed at enhancing access of the banking sector to liquidity and at facilitating the functioning of the euro-area money market. Given the topic of the current conference, I would like to take the opportunity to elaborate on one of these non-standard measures, namely the Securities Market Programme, or SMP. Sovereign yields are central in the transmission of monetary policy, in particular because government bonds provide a floor to the private-sector funding costs. This is the reason why we launched the SMP. 2  BIS central bankers’ speeches  I insist that, through the implementation of all its non-conventional measures – including the SMP – the Eurosystem has fully played its expected role as a lender of last resort (LLR), by which I mean that we have and we will intervene to stem liquidity crises that threaten the stability of the banking system. Having said that, it is clear that engaging in large-scale asset purchases of sovereign bonds is well beyond what should be expected of a central bank’s role as a LLR. Moreover, largescale asset purchases are not without risks. While they may help to alleviate upward pressures on long-term interest rates in the short run, they could also affect price and financial stability in the medium-run, by endangering the value of the central-bank money.
The fact that both public and private indebtedness had followed an unsustainable pace of growth over the previous decade then makes area-wide adjustments both necessary and painful. Among the factors that contributed to the excess of the pre-crisis period stands in my view the misleading belief that sophisticated financial engineering was able to achieve close-toperfect risk diversification and market completeness led in fact to excessive risk-taking by banks. This is in sharp contrast with the current situation, in which investors have doubts about even the risk-freeness of sovereign bonds of developed economies. Restoring market confidence is a difficult and potentially lengthy task. That said, all actions that are consistent with the commitment of governments to address national fiscal imbalances and structural impediments to real growth are likely to accelerate this process. Besides, it is clear that nominal long-term anchors are also of the essence to reduce uncertainty and facilitate such reforms. The primary mandate and the best possible contribution of the Eurosystem is precisely to ensure price stability in the medium run. Then, to the extent that dysfunctional financial-markets are likely to jeopardize our ability to maintain stable prices in the medium run, the Eurosystem must intervene. This analysis has motivated our decisions in the past and will continue to motivate future ones. This brings me to the second part of my talk today. 2.
