KIEV, Nov. 15 – Weakening of the hryvnia exchange rate seen this week, despite favorable fundamental external factors, is linked to political instability, Deputy of the National Bank of Ukraine Governor Oleh Churiy said.

"Ukraine continues receiving large currency income from exports of grain and oil and the steel and iron ore prices on the global markets started growing, worsening of political tension causes nervousness on the currency market and neutralizes the influence of favorable factors," the NBU's press service reported, citing Churiy.
