Floating Bands of the Argentine Peso (Sebastian.Waisgold)

The BCRA (Central Bank of the Argentine Republic) announced that as of Monday, April 15, 2025, the Argentine Peso (USDARS) will float within a system of divergent exchange rate bands.
The upper band was set at ARS 1400 per USD on 15/04/2025, with a +1% monthly adjustment distributed daily, rising by a fraction each day.
The lower band was set at ARS 1000 per USD on 15/04/2025, with a –1% monthly adjustment distributed daily, falling by a fraction each day.
This indicator is crucial for anyone trading USDARS, since the BCRA will only intervene in these situations:
- Selling: if the Peso depreciates against the USD above the upper band.
- Buying: if the Peso appreciates against the USD below the lower band.
Therefore, this indicator can be used as follows:
- If USDARS is above the upper band, it is “expensive” and you may sell.
- If USDARS is below the lower band, it is “cheap” and you may buy.
It can also be applied to other assets such as:
- USDTARS
- Dollar Cable / CCL (Contado con Liquidación), derived from the BCBA:YPFD / NYSE:YPF ratio.
A mid band—exactly halfway between the upper and lower bands—has also been added.
Once added, the indicator should look like this:

User Configuration
By double-clicking any line you can adjust:
- Start day (Dia de incio), month (Mes de inicio), and year (Año de inicio)
- Initial upper band value (Valor inicial banda superior)
- Initial lower band value (Valor inicial banda inferior)

It is recommended not to modify these settings for the Argentine Peso, as they reflect the BCRA’s official framework. However, you may customize them—and the line colors—for other assets or currencies implementing a similar band scheme.
