REUTERS Deputy Governor of the National Bank of Ukraine (NBU) Dmytro Sologub says the country&#39;s public debt at the end of 2019 will be below 55% of GDP due to the strengthening of Ukraine&#39;s national currency, the hryvnia, while earlier this ratio exceeded 80%.

"But, at the same time, let&#39;s imagine an investor who looks at a country with a public debt of 60% of GDP, and an investor who sees a country with a public debt of less than 50% of GDP. And how does this translate into his expectations of the interest rate on this country&#39;s borrowings?" he said. As UNIAN reported earlier, Ukraine&#39;s national currency in September 2019 strengthened by over 4% against the U.S. dollar, and by over 12% from the beginning of the year. In late September, the hryvnia once again updated its four-year high historical maximum at UAH 24.08 per U.S. dollar against UAH 28.08 year-over-year.
