Ukraine is starting to consider a shift away from the U.S. dollar, possibly linking its currency more closely to the euro amid the splintering of global trade and its growing ties to Europe, Central Bank Governor Andriy Pyshnyi told Reuters.

Potential accession to the European Union, a “strengthening of the EU’s role in ensuring our defense capabilities, greater volatility in global markets, and the probability of global-trade fragmentation,” are forcing the central bank to review whether the euro should be the reference currency for Ukraine’s hryvnia instead of the dollar, Pyshnyi said in emailed remarks.
