"We are going to use and make prepayments of between $1 billion and $1.5 billion in 2013, and this will serve to absorb some of the appreciating pressure that exists in the economy," the minister told a news conference.

Peru's sol closed on Friday at its strongest level in more than 16 years, with a bid price of 2.558 per dollar.

Yield-hungry investors have poured money into emerging markets such as Peru, which has expanded on average by 6 percent a year in the last decade. It currently ranks as South America's fastest-growing economy.

Castilla told reporters he forecasts 2013 economic growth at 6.3 percent, up from 6.0 percent previously. The new number matches the government's growth forecast for 2012.

He also estimated that Peru's exports will expand 3.3 percent in 2013 to about $45.45 billion, recovering from a projected 4 percent decline in 2012 stemming from weaker global demand and lower metals prices.

The minister said an expected increase in the volume of mineral shipments will help boost exports next year. Mining accounts for 60 percent of export revenue in Peru, the world's No. 2 copper and silver producer.

Castilla mentioned the possibility of debt prepayment during an interview with Reuters nearly two months ago. He said the debt prepayment was part of a "liability management policy" that seeks to improve and extend the Andean country's debt profile.

 Paying foreign bonds early would complement other measures the government has applied to curb the sol's rally, such as raising deposit requirements on bank accounts denominated in dollars or allowing local pension funds to invest more money abroad.

Peru has local and foreign debt in dollars and soles that are equivalent to about $36.6 billion, or nearly 20 percent of gross domestic product. About $20 billion is foreign debt, according to the central bank.
