[Besent Discloses U.S. Treasury's Purchase of Argentine Pesos at Unofficial Exchange Rate] According to a report by Jinse Finance, U.S. Treasury Secretary Besent announced on Friday via the social media platform 'X' that the U.S. Treasury purchased Argentine pesos on Thursday at the parallel exchange rate known as the 'blue chip swap.' This move boosted the performance of Argentine bonds. This marks the first time Besent has disclosed such foreign exchange intervention. Previously, the U.S. Treasury had purchased pesos in Argentina's local market at the official exchange rate. Following the announcement, Argentine dollar bonds rose, with bonds maturing in 2035 reversing early losses and gaining 0.2 cents per dollar. Despite the U.S. Treasury's intervention, the parallel market exchange rate still fell nearly 1.4% on Thursday. Argentina's official exchange rate is accessible through banking channels, but various unofficial exchange rates are widely used by the public in financial and cash transactions, some of which are legal while others operate in a gray area.
