REUTERS Governor of the National Bank of Ukraine (NBU) Yakiv Smolii has said political uncertainty did not affect the foreign exchange market of Ukraine, while the hryvnia exchange rate is formed only under the influence of market supply and demand. "Double elections are really connected with the expectations of certain risks in financial markets. But this absolutely in no way affected the exchange rate. It keeps being formed due to supply and demand," he told a briefing. According to Smolii, favorable conditions for Ukrainian exports, the inflow of investments from non-residents into Ukraine&#39;s debt securities, as a result of which the supply of currency in the market grew, have been the factors of strengthening the hryvnia in recent times.
