We analyze time-varying exchange rate co-movements and volatility spillovers between the Czech koruna, the Polish zloty, the Hungarian forint and the dollar/euro from 1999 to 2016. We apply the dynamic conditional correlations (DCC) model and the Diebold Yilmaz spillover index to examine the periods prior to and during the GFC, plus during and after the EU debt crisis. We found declining conditional correlations between new EU exchange rates prior to both crises. During the GFC and the European debt crisis, the correlations reach the lowest level, and increase afterwards. Based on the DCC model results we calculate portfolio weights and hedge ratios. We show that during both crises portfolio diversification benefits increase but hedging costs rise as well. Based on the spillover index we document that during calm periods most of the volatilities are due to each currency's own history. However, during the distress periods volatility spillovers among currencies increase substantially. Terms of use: Documents in

Methodology to analyze intra-day data from 2011-2015. Our comprehensive analysis of the wide variety of macroeconomic information during the post-GFC period shows that: (i) macroeconomic announcements affect the value of the new-EU-country exchange rates, (ii) the origin of the announcements matters, (iii) the type of announcement also matters, (iv) different types of news (good, bad, or neutral) result in different reactions, (v) markets react not only after the news release but also before, (vi) when the U.S. dollar is a base currency the impact of the news is larger than in case of the euro, (vii) announcements on ECB monetary policy result in stronger effects than those of the Fed, and (viii) temporary inefficiencies are present on the new-EU-country forex markets.

We analyze the impact of Eurozone/Germany and U.S. macroeconomic news announcements and the communication of the monetary policy settings of the ECB and the Fed on the forex markets of new EU members. We employ an event study methodology to analyze intra-day data from 2011-2015. Our comprehensive analysis of the wide variety of macroeconomic information during the post-GFC period shows that: (i) macroeconomic announcements affect the value of the new-EU-country exchange rates, (ii) the origin of the announcement matters, (iii) the type of announcement matters, (iv) different types of news (good, bad, or neutral) result in different reactions, (v) markets react not only after the news release but also before, (vi) when the U.S. dollar is a base currency the impact of the news is larger than in the case of the euro, (vii) announcements on ECB monetary policy result in stronger effects than those of the Fed, (viii) temporary inefficiencies are present on new-EU-country forex markets, (ix) new-EUcountry exchange rates react differently on positive US news during the EU debt crisis when compared to the rest of the period.

This paper analyses the impact of German macroeconomic news announcements and ECB meeting days on the conditional volatility of the Czech, Polish, and Hungarian Foreign Exchange markets as proxied by CZK/EUR, PLN/EUR, and HUF/EUR exchange rate returns over six years (2010)(2011)(2012)(2013)(2014)(2015). A currency intervention period (11/2013-2015) in the Czech Republic is examined separately. EGARCH-type models with normal and Student's t-distributions are employed. The comprehensive analysis shows the following results. (i) The IFO index, Factory Orders increase and the PMI index from the Service Sector, the labour market data decrease conditional volatility of PLN/EUR. (ii) The IFO index and Industrial Production increase conditional volatility of HUF/EUR on the day of the announcement. (iii) Data from the labour market has a calming effect on CZK/ EUR after the central bank launched currency interventions. (iv) IFO index increases and the PMI index from the Manufacturing Sector decreases conditional volatility of CZK/EUR before currency interventions were introduced (2010-11/2013).
