Will Mexico enact additional mining duty or tax increases affecting CDE by year-end 2026?

Mexico increased mining duties by 1% in 2024. Enacting another increase within 2 years would be aggressive even by Latin American standards. While Morena's supermajority enables action, the political cost of discouraging foreign mining investment provides a check. Record commodity prices create political pressure but also generate record tax revenue under existing rates. Base rate of ~20-30% for any given year.

The 2024 mining duty increase was part of a broader fiscal reform. Standalone mining tax increases between major reform cycles are less common. Mexico's fiscal position is pressured but mining taxes are a small portion of overall revenue. USMCA renegotiation may constrain aggressive taxation. The base rate for consecutive-year mining tax changes is lower than the general annual rate.

Resource nationalism is a global trend that has been accelerating. Chile, Peru, and Indonesia have all moved toward higher mining royalties. Mexico's Morena government has been ideologically aligned with this trend. Record commodity prices make the political case easier. The question is whether legislative bandwidth exists for another mining-specific change so soon after 2024. I weight the global trend slightly higher than the 'too soon after 2024' argument.

Two mining tax changes in consecutive years would be unusual for Mexico. The 2024 increase was recent enough that political capital for another round is limited. Current rates are already generating record revenue. The resolution criteria require enacted legislation by year-end, which means the political process would need to start relatively soon. No specific proposals are currently on the table.

Without a specific legislative proposal on the table, the probability of enacting a new mining tax by year-end is low. Legislative processes in Mexico typically take 3-6 months from proposal to enactment. The clock is running and no visible movement increases my confidence in NO. The base rate for mining-specific tax changes in any given year is ~15-25%.

Mexico's fiscal trajectory is concerning and could force revenue-raising measures. However, mining-specific taxes are not the most likely vehicle — broader fiscal reform or energy sector changes are more probable. The mining sector has vocal defenders in Congress representing mining states. Probability slightly above the base rate given global trends but still a minority outcome.

Recent 2024 increase, no current proposals, record revenue under existing rates. Global resource nationalism trend provides some uplift but consecutive-year changes are uncommon. Low probability.

Morena supermajority and fiscal pressures create the possibility, but the 2024 change is too recent for another round. Mining sector employment provides political protection. Base rate suggests ~25% probability.

Balance of evidence points to ~25-30% probability. Global trend supports higher rates eventually but the specific 2026 timeline and recent 2024 change make it less likely for this particular year.
