Buenos Aires: a Big Mac price that doubles every few months
Buenos Aires posts the most volatile Big Mac price in the entire dataset. The peso-denominated price has moved from ARS 7 in 2010 to over ARS 7,300 in 2025 — a 1,000-fold rise in 15 years. Anyone watching Buenos Aires Big Mac prices in real time has been reading more honest inflation data than INDEC's published CPI series for most of that period.
For Big Mac Index analysts, Buenos Aires is the cleanest single-city case of currency debasement showing up at the menu board faster than at the official statistics agency. The 2024-2025 Milei stabilization program has slowed the rate of peso-denominated price growth meaningfully, but the cumulative damage is permanent — the absolute price level can never reverse to 2010 territory. Watch the rate of price increase, not the level: a flattening rate is the actual stabilization signal.
