The OCA index which is based on predicted value of nominal exchange rate variability is used to consider the suitability of monetary union membership. The index is estimated in two steps. First, relationship between the volatility of the nominal exchange rate and the fulfilment of the OCA criteria is estimated on a sample of 11 countries (EU-10 and the euro area) over the period 1999 – 2009. Subsequently, OCA index is calculated as the predicted value of the nominal exchange rate variability EU-10 countries to the euro.
