But uncertainties arise not just because there will always be unexpected events, changes of technology and taste. We also continually review and update our views on the underlying relationships between countries, firms and people. And of course we are constantly learning more about the past not least as the statistics get revised. We try to emphasise those uncertainties by always publishing our forecasts in the form of fan charts which show not just a central projection but a probability distribution around it. If you go back a year to May 2006, our central projections for Q2 2007 were for growth of about 3% and inflation of around 2%. But we also showed about a one in four chance that growth would be a percentage point or more away and that inflation would be half a percentage point from the central projections (Chart 2). It follows that there is also a range of uncertainty around the right path for interest rates. The story of the last year has been that growth has been stable (between 0.7 and 0.8% each quarter) and kept quite close to that central projection but only on the basis of substantially higher interest rates than our forecasts were based on; inflation has been higher than we projected again despite the successive rises in rates. You might expect this range of uncertainty to be reflected in a range of independent forecasts, but you would be disappointed. Most forecasters operate models much like ours and, of course, they use the same data.
Christine Lagarde: ECB press conference - introductory statement Introductory statement by Ms Christine Lagarde, President of the European Central Bank, and Mr Luis de Guindos, Vice-President of the European Central Bank, Frankfurt am Main, 15 June 2023. *** Good afternoon, the Vice-President and I welcome you to our press conference. Inflation has been coming down but is projected to remain too high for too long. We are determined to ensure that inflation returns to our two per cent medium-term target in a timely manner. The Governing Council therefore today decided to raise the three key ECB interest rates by 25 basis points. The rate increase today reflects our updated assessment of the inflation outlook, the dynamics of underlying inflation, and the strength of monetary policy transmission. According to the June macroeconomic projections, Eurosystem staff expect headline inflation to average 5.4 per cent in 2023, 3.0 per cent in 2024 and 2.2 per cent in 2025. Indicators of underlying price pressures remain strong, although some show tentative signs of softening. Staff have revised up their projections for inflation excluding energy and food, especially for this year and next year, owing to past upward surprises and the implications of the robust labour market for the speed of disinflation. They now see it reaching 5.1 per cent in 2023, before it declines to 3.0 per cent in 2024 and 2.3 per cent in 2025. Staff have slightly lowered their economic growth projections for this year and next year.
