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:
