NY -- Standard&Poor's CreditWire 1/30/97 -- Standard&Poor's today has assigned its triple-`B'-minus rating to the Republic of Argentina's Argentine Peso (ARP) 500 million Europeso bond due 2007. The rating outlook is stable. Additionally, Standard&Poor's has affirmed its `A-3' rating on the Republic's outstanding peso-payable Letes, and its triple-`B'-minus long-term Peso credit rating on the Republic, ratings which were first assigned in 1994. At the same time, Standard&Poor's has affirmed its double-`B'-minus rating on the Republic's long-term foreign currency-payable debt, including Brady bonds and its single-`B' rating on Argentina's short-term foreign currency debt. Standard&Poor's higher local currency rating acknowledges the government's relatively stronger proven and prospective ability to service peso-payable debt,
