Mexican Peso weakens as Iran sanctions offset Mexico’s inflation data
- USD/MXN climbs as US-Iran sanctions weigh on Peso.
- Mexico inflation accelerates, but core price pressures ease slightly.
- Softer GDP growth limits support before Jackson Hole speech.
The Mexican Peso (MXN) loses ground against the Greenback on Monday, even though economic data showed that inflation accelerated in the first half of August, while economic growth was softer than expected. Consequently, the USD/MXN pair trades with gains of over 0.25% to 16.96.
USD/MXN weakens as US sanctions lift caution despite firmer Mexican inflation
Economic data from Mexico showed that headline inflation rose from 3.1% to 3.26% in the first 15 days of August, according to the national statistics agency. Underlying inflation, which excludes volatile items, cooled by two-tenths of a percentage point, from 3.95% to 3.94%.
At the same time, the Gross Domestic Product (GDP) for the second quarter expanded by 1.4%, up from the -0.3% contraction witnessed in Q1 2026, but missed estimates for a 1.5% increase.
Even though the data could have warranted further upside, US sanctions on Iran, levied by the Treasury Department, capped the Mexican currency’s advance.
Mexico's President Claudia Sheinbaum is seeking a trade deal with the US, following US President Donald Trump's imposition of tariffs on Canada. Worth noting that the US imposed 50% tariffs on certain Canadian goods as bilateral talks collapsed.
US Treasury Secretary Scott Bessent announced “unprecedented” economic measures against Iran, targeting vital lifelines such as digital assets, technology, Gold, aviation, and shipping. The economic D-Day called Operation Outcast sanctioned nearly 60 entities linked to Iran, including broker networks and shadow fleet vessels across several countries. The actions aim to cut funding for the IRGC.
Aside from this, traders eye the release of US growth, inflation and jobs data, as well as Fed Chair Kevin Warsh’s speech at the Jackson Hole Symposium on Friday.
USD/MXN Price Forecast: Technical outlook
In the daily chart, USD/MXN trades at 16.9564, extending its decline below the cluster of longer-term simple moving averages (SMA) which now cap the upside near 17.3341. Price also remains under the nearer downward resistance trendline break at 17.3653, reinforcing a bearish tone despite the Relative Strength Index (RSI) at 31.55 edging away from oversold territory and hinting at only modestly stabilizing momentum.
On the topside, initial resistance is seen at the triple SMA cluster around 17.33, followed by the more recent downward trend-line break near 17.37, where sellers are likely to reassert control if a corrective bounce develops. On the downside, the longer-term descending trendline break level at 15.51 acts as a distant structural support zone, with the current setup suggesting that any recovery will struggle while USD/MXN trades beneath the 17.33–17.37 band.

Mexican Peso FAQs
The Mexican Peso (MXN) is the most traded currency among its Latin American peers. Its value is broadly determined by the performance of the Mexican economy, the country’s central bank’s policy, the amount of foreign investment in the country and even the levels of remittances sent by Mexicans who live abroad, particularly in the United States. Geopolitical trends can also move MXN: for example, the process of nearshoring – or the decision by some firms to relocate manufacturing capacity and supply chains closer to their home countries – is also seen as a catalyst for the Mexican currency as the country is considered a key manufacturing hub in the American continent. Another catalyst for MXN is Oil prices as Mexico is a key exporter of the commodity.
The main objective of Mexico’s central bank, also known as Banxico, is to maintain inflation at low and stable levels (at or close to its target of 3%, the midpoint in a tolerance band of between 2% and 4%). To this end, the bank sets an appropriate level of interest rates. When inflation is too high, Banxico will attempt to tame it by raising interest rates, making it more expensive for households and businesses to borrow money, thus cooling demand and the overall economy. Higher interest rates are generally positive for the Mexican Peso (MXN) as they lead to higher yields, making the country a more attractive place for investors. On the contrary, lower interest rates tend to weaken MXN.
Macroeconomic data releases are key to assess the state of the economy and can have an impact on the Mexican Peso (MXN) valuation. A strong Mexican economy, based on high economic growth, low unemployment and high confidence is good for MXN. Not only does it attract more foreign investment but it may encourage the Bank of Mexico (Banxico) to increase interest rates, particularly if this strength comes together with elevated inflation. However, if economic data is weak, MXN is likely to depreciate.
As an emerging-market currency, the Mexican Peso (MXN) tends to strive during risk-on periods, or when investors perceive that broader market risks are low and thus are eager to engage with investments that carry a higher risk. Conversely, MXN tends to weaken at times of market turbulence or economic uncertainty as investors tend to sell higher-risk assets and flee to the more-stable safe havens.
