Argentina sells dollars to curb peso slide as new rules kick in
Argentina’s Treasury sold dollars Friday, looking to limit the decline of the peso on the first day that new FX rules kicked in.
Under the new framework, announced in December, the peso’s trading bands will expand at the same rate as monthly inflation instead of being capped at one percent per month.
In October I posted a community script which visualized these upper and lower currency bands. At the time I mentioned the flaws in that script. Well now there is a much better chart that someone has published this week. Reflects the Jan-01 changes of the fx bands following inflation that is discussed in the above posted article
Here is the link to that community chart and source code for review. The screenshots for today. The well documented script comments are copied here too, explaining how it will automatically update every month
Argentina FX Bands — Indicator by EcoValores

// ENGLISH DESCRIPTION:
// This indicator plots Argentina's exchange rate band system ("Bandas Cambiarias")
// implemented by the BCRA (Central Bank) starting April 11, 2025.
//
// The system defines a floor and ceiling for the ARS/USD exchange rate:
// - Phase 1 (Apr 11, 2025 - Dec 31, 2025): Floor decreases 1%/month, ceiling increases 1%/month
// - Phase 2 (Jan 1, 2026 onwards): Both bands adjust by inflation (with 2-month lag)
//
// When the exchange rate hits the floor, BCRA buys USD (accumulates reserves).
// When the exchange rate hits the ceiling, BCRA sells USD (defends the band).
// Within the band, the rate floats freely ("flotación entre bandas").
//
// For future projections, the indicator assumes next month's inflation equals
// the last known inflation, unless you specify a custom value.
