The U.S. Senate Committee on Banking, Housing and Urban Affairs’ Ranking Member, Senator Elizabeth Warren, published a letter to U.S. Treasury Secretary Scott Bessent calling for the termination of a USD 20 billion line of credit supporting Argentina’s financial markets and requesting documentation on the arrangement. Warren referenced Treasury’s September 2025 announcement of its intent to use the Exchange Stabilization Fund (ESF) to support Argentina, and noted Treasury’s statement that Argentina repaid an initial USD 2.5 billion draw by December 2025 and that the transaction was “closed.” The letter argues Treasury has not confirmed whether the underlying Exchange Stabilization Agreement (ESA) with the Central Bank of Argentina has been terminated, suggesting the broader USD 20 billion facility may still be available. The letter requests a copy of the ESA and written confirmation that it has been terminated, with a response due no later than February 12, 2026.
