The new government won’t commit to a target date for joining the euro, even as exporters suffer from the strengthening koruna, Prime Minister Petr Nečas said. He said the country will benefit from a flexible exchange rate as consumer prices converge with those in richer European Union-member states, and rapid euro adoption would risk fueling inflation. The koruna has gained 3.7% against the euro this month, the most among 177 currencies tracked by Bloomberg.
