U.S. banks are in discussions to secure collateral or guarantees from the U.S. Treasury for a proposed $20 billion loan facility intended to stabilize Argentina's peso. The plan, which involves a USD-backed swap, remains in preliminary stages with no formal terms yet established. Argentina's peso has plummeted to record lows due to ongoing economic challenges, prompting the U.S. Treasury to intervene by purchasing pesos to enhance liquidity. Analysts emphasize that the success of this facility hinges on Washington's backing and clear collateral arrangements.
