Volatility changes in European currency exchange rates due to EMS announcements

This study examines the effects of announcements concerning European Monetary Union on the exchange rate volatilities of several European currencies. It is expected that when good news is portrayed in regard to a single currency this will be considered bad news, thus eliciting a negative reaction, for the German mark. Conversely, good news for a single currency should also be good news for weaker currencies, such as the Portuguese escudo, the Italian lira, the Greek drachma, and the Spanish peseta. In terms of volatility, a reaction to good news should be a reduction in volatility, as bad news should cause an increase in volatility. In total there are 22 announcements examined from January 1986 through September 1997. The German mark is observed to experience greater increases in volatility than decreases, as does the Italian lira. Portugal and Greece appear to react more strongly to positive news in that the decreases in volatility are on average greater than the increases.
