Issue 14| May 2011 Did nominal exchange rate flexibility matter during the global recession? A Czech and Slovak case study Anton Jevčák Introduction – a tale of two exchange rate regimes Summary On 8 July 2008, the ECOFIN Council decided that Slovakia would Prior to Slovakia’s entry into the join the euro area on 1 January 2009 and set the rate at which the euro area, Slovak and Czech NEER movements were highly correlated. Slovak koruna would be converted into euro. The conversion rate During the financial crisis, the Czech was set equal to the prevailing central rate of the Slovak koruna (SKK) koruna temporarily weakened against in the Exchange Rate Mechanism II (ERM II). The nominal exchange the euro, while the Slovak exchange rate against the euro was thus effectively fixed by this decision. This was rate versus euro was already de facto confirmed by subsequent market developments, with SKK trading close fixed since mid-2008. Given the to the conversion rate until the end of 2008 despite considerable global otherwise comparable economic structure and level of development financial market turbulences. Meanwhile, the Czech Republic continued of the two countries, this brief to enjoy full exchange rate flexibility. The exchange rate of the Czech analyses whether the switch in its koruna (CZK) depreciated sharply against the euro between July 2008 monetary policy regime (joining the and February 2009 and, despite a subsequent strong rebound, it euro area) had any significant impact remained weaker than its June 2008 level until the end of 2010. on how the Slovak economy coped during the recent crisis period as Graph 1: Exchange rate versus the euro compared to its Western neighbour. 90 The analysis suggests that both Index June 2008 = 100 economies continued to evolve in a 95 (inverted scale) highly similar manner.
