Incoming information, while somewhat weaker than expected, remains overall consistent with an ongoing broad-based expansion of the euro area economy and gradually rising inflation pressures. The underlying strength of the economy continues to support our confidence that the sustained convergence of inflation to our aim will proceed and will be maintained even after a gradual winding-down of our net asset purchases. At the same time, uncertainties relating to protectionism, vulnerabilities in emerging markets and financial market volatility remain prominent. Significant monetary policy stimulus is still needed to support the further build-up of domestic price pressures and headline inflation developments over the medium term. This support will continue to be provided by the net asset purchases until the end of the year, by the sizeable stock of acquired assets and the associated reinvestments, and by our enhanced forward guidance on the key ECB interest rates. In any event, the Governing Council stands ready to adjust all of its instruments as appropriate to ensure that inflation continues to move towards the Governing Council’s inflation aim in a sustained manner. Let me now explain our assessment in greater detail, starting with the economic analysis. Euro area real GDP increased by 0.4%, quarter on quarter, in both the first and the second quarter of 2018. Incoming information, while somewhat weaker than expected, remains overall consistent with our baseline scenario of an ongoing broad-based economic expansion, supported by domestic demand and continued improvements in the labour market. Some recent sectorspecific developments are having an impact on the near-term growth profile.

But capital flows may also demonstrate an imbalance between demand and output in an economy, which must eventually correct if debt and wealth stocks are not to become unsustainable. Sharp corrections in rates of domestic absorption and/or capital flows could then result, with attendant output costs. In that sense, global imbalances may also be bad cholesterol. 1 So which are capital flows today? Historical evidence is illuminating. Chart 1 plots (the absolute value of) current account balances in thirteen countries, as a % of GDP, since 1880. Other than in wartime, global imbalances are at their highest in well over a century. They have surpassed levels which prevailed during the classical Gold Standard and are more than twice levels during the Bretton Woods period (Chart 2). For some individual countries, these capital flows look larger still, both absolutely and relative to historical norms (Chart 3). It is not just the size of these global flows that is unusual. So too is their direction. Contrary to theory, capital is flowing from developing countries with a low capital stock, towards developed countries with a high capital stock (Lucas (1990)). In other words, capital is flowing “uphill”, away from countries where the marginal product of capital should be high and towards countries where it should be low. This makes the pattern of global capital flows doubly perplexing. 1  Blanchard and Milesi-Ferretti (2009) discuss the causes of “good” and “bad” imbalances.
