The U.S. Treasury finalized a $20 billion currency swap framework with Argentina and bought pesos in the open market on Thursday, making good on President Donald Trump's pledge to prop up the wobbling country and sending the peso and Argentine dollar bonds sharply higher. Milei, who is due to meet Trump next week during the IMF and World Bank annual meetings in Washington, thanked Bessent and Trump in a message on X. "Together, as the closest of allies, we will make a hemisphere of economic freedom and prosperity. We will work hard every day to provide opportunity for our people," Milei wrote.
