Mexico's inflation data is the key basis for interest rate adjustments by the Central Bank of Mexico (Banxico). If inflation data unexpectedly deviates from forecasts, it will directly trigger fluctuations in the Mexican Peso (USD/MXN) exchange rate and price adjustments in the Mexico ETF (EWW), representing a typical tradable macro event.

April 6, 2026 - April 8, 2026, the price of '3.00% to 3.49%' surged from 11.3c to 35.5c. This was likely driven by market repricing following the latest domestic monthly price index data or central bank guidance, causing capital to flood into this target inflation bracket. March 20, 2026 - March 22, 2026, the price of '3.00% to 3.49%' crashed from 34.65c to 19.55c. This was likely due to capital re-evaluating the difficulty of achieving this lower inflation bracket after a brief pricing anomaly, leading to a liquidity drawdown. March 7, 2026 - March 9, 2026: Multiple mid-range options experienced a price crash: '3.50% to 3.99%' dropped from 30c to 16c, '4.50% to 4.99%' from 27c to 11.5c, and '3.00% to 3.49%' from 24c to 10.5c. Reason: This is likely a reaction to the monthly inflation data release combined with a liquidity crunch or correction from previously inflated levels (where Sum was > 150%). While prices corrected sharply, some buckets (like 3.5-3.99%) may have swung from overvalued to undervalued, while tail options remain expensive.

The total implied probability in the prediction market currently exceeds 100% (sitting near 161%), which is an extreme structural divergence. Additionally, the market prices a bimodal distribution (34.4% for 3.0-3.49% and 31.65% for 5.0-5.49%), which strongly contradicts the mainstream economic expectation of a normal distribution centered around a smooth convergence to target inflation. This divergence is primarily driven by fragmented platform liquidity and an absence of market makers, rather than a genuine macroeconomic disagreement.
