Convertibility is distinguished between current account transactions — exchange for payment of goods, services, and income transfers — and capital account operations, that is, for investments and financial asset movements. The latter is established later and usually accompanied by numerous conditions.
With limited convertibility, a gap arises between the official and actual exchange rate, and currency access is distributed administratively. This distorts pricing and complicates investment valuation: calculated returns in national currency cease to correspond to what is actually achievable.
In Uzbekistan, the liberalization of the foreign exchange market in 2017 removed major restrictions on current account exchange and eliminated the gap between the official and market rate. This changed business operating conditions and made sum and foreign currency returns comparable.
For a private investor, the degree of convertibility determines the practical ability to redistribute savings between currencies and repatriate income. It should be assessed not by formal status, but by the actual transaction procedure, including limits, timeframes, and commissions.
