Mexico announced a sovereign debt default in August 1982, marking a major turning point in the Latin American debt crisis.
Mexico’s government said it could no longer service its external debt after international interest rates rose, oil revenues weakened, and foreign lenders became unwilling to roll over loans. The announcement alarmed banks and governments that had lent heavily across Latin America.
Many countries in the region had borrowed extensively during the 1970s, when international banks recycled large flows of petrodollars. Higher U.S. interest rates in the early 1980s sharply increased debt-service costs, while recession reduced export earnings.
The crisis led to rescheduling negotiations, austerity programs, bank losses, and a prolonged period often called the “lost decade” for Latin America. Mexico’s announcement did not mean every country defaulted at the same moment; it was the major warning that made the region-wide nature of the debt problem unmistakable.
