An increase in net household demand for foreign currency to $270–280 million in June–July, up from $250 million in May, falls within the margin of statistical error and confirms the effectiveness of the policy of the National Bank of Ukraine (NBU) aimed at maintaining the appeal of hryvnia assets and relative stability in the currency market. This is in contrast to last year or early this year, when net demand reached as high as $1 billion per month, First Deputy Governor of the NBU Serhiy Nikolaychuk told Interfax-Ukraine.
