In 2001 the current account deficit dropped to about 2.2% of GDP (US$1.17 billion)--from 3.1% in 2000—while the trade balance registered a small deficit. Exports dropped slightly to $7.11 billion, while imports fell 2.1% to $7.20 billion. After being hit hard by El Niño in 1998, fisheries exports have recovered, and minerals and metals exports recorded large gains in 2001 and 2002, mostly as a result of the opening of the Antamina copper-zinc mine.

After several years of substantial growth, foreign direct investment not related to privatization fell dramatically in 2000 and 2001, as well as in the first half of 2002. Net international reserves at the end of May 2002 stood at $9.16 billion, up from $8.6 billion (2001), $17 billion at the end of 2006, over $20 billion in 2007, and over $35 billion in May 2008.
