KIEV, May 6 – Ukraine's international reserves 2016 expanded by 4.1%, or $519.5 million, to $13.241 billion, in April, according to rough estimates, the National Bank of Ukraine reported on its website on Friday.

"The reserves grew in April mainly due to foreign currency purchases by the NBU to balance excess wobbling on the interbank forex market and due to the replenishment of reserves. Net foreign currency purchases by the NBU during the month totaled $675.8 million. In particular, it conducted 13 forex auctions last month where it bought a net amount of $528.4 million. The NBU did not hold auctions to sell foreign currency in April," the central bank said.
