The Central Bank of Argentina opened a public consultation on a draft regulation to create the Tasa de Intereses Moratorios (TIM), a reference rate intended to help courts determine late-payment interest under Article 768(c) of Argentina’s Civil and Commercial Code. Under the proposal, TIM would be calculated from the average of a passive rate (30-day ARS time deposits) and an active rate (a weighted average of rates on ARS loans granted via signature-only documents and personal loans). The resulting daily effective rate would be bounded by bands linked to the daily change in the Coeficiente de Estabilización de Referencia (CER), with a ceiling of CER plus 3% effective per annum and a floor of CER minus 3% effective per annum. The central bank also made available the draft resolution with a methodological annex, a historical TIM series in Excel, and a calculator to estimate interest and total amounts for a given principal and period. The consultation is open until 19 December and submissions are non-binding but will be considered during the review stage.
