But in many countries narrower external imbalances have come at the cost of demand compression due to recession and of increased internal imbalances (decrease in output and high unemployment). Now there is the risk that flow imbalances will increase again. At the same time stock imbalances have widened further. Imbalances within the euro area became more persistent with the adoption of the euro. The leading position of the US dollar in the world monetary system also contributes to global imbalances persistence. There are strong differences in views regarding the causes of global imbalances and their macroeconomic effects. But it is clear that there are strong political and economic imperatives that require consistent macroeconomic policy implementation needed to reduce remaining external imbalances and to prevent new emerging imbalances.
