Formal analysis of exchange rate co-movements • Data: Bloomberg, 01/01/1994 – 30/08/2005, Daily • Methodology: time varying correlation coefficient (estimated as bi-variate GARCH) where NC = national currency • Possible outcomes: 0 <= |corr| <= 1 corr = 0: NC is not related to Euro at all corr = 1: NC = Euro
Results: Dynamic correlations HUF/USD and EUR/USD CZK/USD and EUR/USD PLZ/USD and EUR/USD SKK/USD and EUR/USD Sources: Bloomberg, CNB calculation.
