The reserves shrank by 4.4% in the first six months.
Ukraine saw a 1.1% decline in its international reserves in June 2018, to US$17.978 billion as of July 1, 2018.
The National Bank of Ukraine said on its website that the reduction in the reserves was related to the payment of public debt in foreign currency.
Since the beginning of the year, the reserves have decreased by 4.4%.

It is noted that the main source to replenish the reserves in June was the sale of government bonds denominated in foreign currency, while the purchase of foreign currency by the National Bank in the interbank market was no longer the main source of the replenishment of the reserves.
This was due to certain deterioration in prices on foreign markets for Ukrainian exports and a reduction in international investors' interest in emerging markets.
In addition, the reserves were affected by the revaluation of financial instruments (change in market value, the hryvnia forex rate against foreign currencies) in the amount of $38.2 million.
The NBU also said that the amount of the reserves as of July 1 covers 3.2 months of future imports and is sufficient to fulfill the obligations of Ukraine and the current operations of the government and the National Bank.
