Europe's gas and power concerns have been fading recently, driven by a fortuitous combination of a mild winter and lower demand for energy. This is good news. But the current gas prices are not low and Europe's gas supply remains fragile. Elevated energy prices are a significant contributor to inflation and a large drag on European growth for this year, at least. 

With inflation running at its highest level over several decades and forecasted to stay high in the next year, many people are concerned that the sharp increase in the price level will erode their standard of living and hence their life satisfaction. 

Inflation is running at its highest level over four decades and is forecasted to stay high and far above central banks' targets also next year. Central banks failed to deliver on their commitment to keeping inflation under control. Fed and ECB can only restore their credibility by acting aggressively to bring inflation down and compensate for their policy, forecasting and communication errors.
