LIMA, Jan 16 (Reuters) - Peru posted a fiscal deficit of 2.1 percent of gross domestic product for 2015, its steepest since 2002, as tax revenue shrank on the back of falling prices for the mined metals it exports, central bank data showed on Saturday.
The nation's second consecutive annual deficit is just below 2.3 percent of GDP in 2002 and much bigger than 0.3 percent posted for 2014.
The 2015 deficit amounted to 12.8 billion soles ($3.74 billion), compared with 2.0 billion soles ($584.86 million) in 2014.
Tax revenue fell 8.3 percent in 2015 to 92.7 billion soles ($27.11 billion) on slumping prices for metals, one of Peru's top exports.
The economy of Peru, the world's third-largest copper, zinc and silver producer, is thought to have grown 2.9 percent in 2015 after a 2.35 percent expansion in 2014, the central bank has estimated.
Peru's economy is seen rebounding in 2016, with expected 4.0 percent growth, according to government forecasts.
