The total term is no longer considered for calculating the minimum cash amount, but rather the time remaining until the customer can cancel. Furthermore, the minimum term is reduced from 180 to 90 days, and the interest rate will be freely agreed upon between the parties, eliminating the minimum of 1% nominal annual interest. On June 5, 2025, through Communication "A" 8252, the Central Bank of Argentina allowed the residual term of said securities at the time of their payment to be considered when integrating the minimum cash requirement in pesos with national government securities. On July 10, through Communication "A" 8277, the Central Bank of Argentina established that financial institutions may carry forward the excess minimum cash requirement in pesos recorded between July and October 2025 to the month following the month in which it was generated. The carryover is not cumulative and is subject to monthly limits. On July 17,2025 through Communication "A" 8281 and Communication "A" 8289 the BCRA raised the minimum cash requirements to 40% for demand deposits and term investments with early redemption that are part of mutual funds, and for borrower-liable securities in pesos, effective August 1. It also increases the demand-based guarantees in pesos by the same percentage. In addition, it reduces the demand requirement that can be paid with government securities by four percentage points. On July 24, 2025 through Communication "A" 8286, the Central Bank of Argentina established that as of July 25, 2025 repos in pesos will be subject to the minimum cash requirement rates for demand-based guarantees, i.e., 25% or 30% depending on their remaining term. On August 14, 2025, through Communication "A" 8302 the Central Bank of Argentina established that: • As of August 18, 2025, the calculation of compliance with the minimum reserve requirement in pesos is modified from the current average to a daily basis. The possibility of transferring shortfalls in the minimum cash integration requirement is eliminated, while transferring excess amounts is maintained. • The fine in pesos applied to minimum cash integration deficiencies is increased to three times the TAMAR (Tamar). • Effective from August 19 to November 28, 2025, the requirement rates in pesos for demand deposits, early redemption deposits for money market FCIs, passive repos, and borrower-liable stock market guarantees (Group A and non-Group A G-SIBs) are increased by 5 percentage points.
