Mexico Inflation Cools More Than Expected, Keeping Peso Under Pressure

Mexico’s headline inflation rose less than analysts had forecast in the first half of March, a development that reinforces expectations for further monetary easing by the Bank of Mexico (Banxico) and is likely to keep the Mexican peso trading with a soft tone in the near term.

Inflation data undershoots expectations

According to data released by Mexico’s national statistics agency (INEGI) on Monday, headline inflation for the first two weeks of March came in at an annual rate of 3.74%, below the median forecast of 3.83% from economists surveyed by Bloomberg. Core inflation, which strips out volatile energy and food prices, also moderated more than anticipated, easing to 3.64% year-on-year from 3.67% in the prior fortnight.

The deceleration was driven primarily by slower price increases in the services and processed food categories, suggesting that domestic demand pressures are continuing to ease. Energy prices, however, provided a slight upward push due to base effects from last year’s subsidies.

Implications for Banxico and the peso

The softer-than-expected inflation reading strengthens the case for Banxico to continue its rate-cutting cycle at its next monetary policy meeting in April. The central bank has already reduced its benchmark interest rate by 150 basis points since August 2024, bringing it to 9.00%. Markets are now pricing in a higher probability of a 25-basis-point cut next month, with some analysts even floating the possibility of a larger 50-basis-point move if inflation continues to surprise to the downside.

For the Mexican peso (MXN), the implications are clear. Lower interest rates reduce the carry advantage that has made the peso one of the best-performing emerging market currencies in recent years. The peso has already weakened by roughly 3% against the US dollar since the start of 2025, and the latest inflation data is unlikely to reverse that trend. The USD/MXN pair is likely to remain supported above the 17.50 level, with risks tilted toward further depreciation toward 18.00 in the coming weeks.

Broader market context

The peso’s soft tone is also being shaped by external factors. A resilient US economy has pushed back expectations for Federal Reserve rate cuts, keeping the dollar broadly bid. Meanwhile, lingering uncertainty over US trade policy and nearshoring dynamics continues to weigh on investor sentiment toward Mexico. The combination of a dovish Banxico and a hawkish Fed creates a challenging backdrop for the peso.

From a global perspective, the disinflation trend in Mexico mirrors developments across much of Latin America. Brazil and Chile have also seen inflation moderate, allowing their central banks to ease policy. However, Mexico’s relatively tighter fiscal stance and its deep integration with the US economy make it particularly sensitive to changes in the interest rate differential.

What this means for investors and consumers

For investors holding Mexican assets, the message is one of caution. The peso’s carry trade appeal is diminishing, and further rate cuts could accelerate capital outflows. Bond yields are likely to decline, which may provide some support for local currency debt, but currency risk is rising.

For Mexican consumers, lower inflation is a welcome relief after the post-pandemic price surge. However, the peso’s weakness could eventually feed through to higher import costs, particularly for goods priced in dollars. The net effect on household purchasing power remains mixed.

Conclusion

Mexico’s below-forecast inflation print provides Banxico with additional room to cut rates, but it also reinforces a soft outlook for the peso. The currency is likely to remain under pressure in the near term as the interest rate differential with the US narrows and external headwinds persist. Investors should watch for Banxico’s forward guidance in April for further clues on the pace of easing.

FAQs

Q1: Why did Mexico’s inflation come in lower than expected?
A1: The main drivers were slower price increases in services and processed food, reflecting easing domestic demand. Energy prices had a slight upward effect but were not enough to offset the broader deceleration.

Q2: How does lower inflation affect the Mexican peso?
A2: Lower inflation gives Banxico more room to cut interest rates. Lower rates reduce the peso’s carry trade appeal, making it less attractive for foreign investors and typically leading to currency depreciation.

Q3: What is the outlook for Banxico’s next rate decision?
A3: Markets now see a high probability of a 25-basis-point cut at the April meeting. A larger 50-basis-point cut is possible if inflation continues to undershoot expectations, though most analysts view that as less likely.
