Coffee prices on the world markets are up, due to the expectations of a freezing weather in Brazil. World market prices have increased to US$121 per 100 pounds, four points more than last week. The increases could benefit Dominican coffee exports that stand at 550 thousand bags per annum, generating US$65 million dollars last year. Coffee producers complain that the Central Bank buys their dollars at the official rate which is approximately 10% less than the market rate.
