This will be based on official INDEC data, based on the Year-over-Year inflation from Dec 2024 compared to Dec 2023. This will presumably be reported in the report released in Jan 2025.

For reference, this is the latest report as of this writing:

This question will not resolve Yes early.

It will resolve No early if the following conditions are met:

• Inflation YTD exceeds 30% as of a given month, as does total YTD as of resolve time.

• The inflation in the following month (after breaking 30% YTD) is positive.

• The market has been consistently trading at or above 97% for at least a week.

• In my judgment there are no weird shenanigans going on and this early-resolve criteria still looks reasonable. If there are weird inflation / deflation things going on I'll bias toward waiting.

Hopefully that allows a good mix of adequate patience and resolving correctly, while also allowing an early resolution if the result is clear in advance.
