The City of Buenos Aires received a credit rating upgrade to AAA for both local and foreign currency issuers from Standard & Poor’s, maintaining a stable outlook. 

The agency credited the upgrade to the city’s ability to maintain consistent fiscal surpluses, prudent financial management, and the accumulation of liquidity reserves. These factors have enabled the city to reduce debt and improve infrastructure despite Argentina’s volatile macroeconomic environment and reductions in government transfers. Local officials noted that the upgrade reflects the city’s financial order and should facilitate better access to financing for future investments.
