CNB Vice Governor Mojmír Hampl warned yesterday that the launch of an EU financial-transactions tax would have a negative effect on the financial sector and is anti-growth. Such a tax was rejected in 2011, but 11 EU countries now want to impose one. They want it to apply to all transactions involving securities issued within the 11 countries (regardless of where the transaction occurred) or mediated by an institution from one of the 11 countries.
