A stronger-than-expected US inflation reading raised the likelihood of further tightening by the Federal Reserve (Fed). Against that backdrop, the Mexican Peso (MXN) regained ground against the US Dollar (USD) on Wednesday, having shed 0.45% in the previous week. USD/MXN stands at 18.60 at the time of writing, a decline of 011%.

Although October's US inflation reading surpassed forecasts, monthly headline CPI slowed to 0.4% from 0.6%. At 0.3% MoM, core inflation was unchanged for a third consecutive month and exceeded economists' 0.2% forecast while matching the scenario outlined by Fed Governor Christopher Waller, who predicted he could favour a 50-basis-point rate increase if underlying inflation reached 0.3%.
Money markets responded by assigning a greater probability to a 25 basis points Fed rate increase in December, according to the CME FedWatch Tool. A quarter-percentage-point December rise is also anticipated by banks including Deutsche Bank and Goldman Sachs.
With expectations of tighter policy providing support, the US Dollar Index (DXY) has risen 0.69% to 102.91. The index, which measures the Dollar against six currencies, earlier reached 102.96, its highest level in 18 months.
Figures released on Monday by Mexico’s National Statistics Agency, known as INEGI, showed annual inflation accelerating to 3.75% in October from 3.45%, exceeding forecasts. Inflation excluding volatile items reached 3.8% YoY, above the 3.78% estimate. Taken together, the readings suggest that last week's rate cut by the Bank of Mexico (Banxico) was unjustified, even though the Governing Board acknowledged that inflation risks were skewed to the upside.
In an interview with El Financiero, Banxico Governor Rodriguez Ceja said the board had been considering rate reductions since October. Following the cut, she added, “maintaining the rate at its current level – 6.25% – for an extended period will support the convergence of inflation to the target and will be adequate to address external macroeconomic challenges.”
With little on Mexico's upcoming economic calendar, traders are taking their lead from developments in the US. North of the border, jobless claims, housing figures, comments from Fed officials and producer inflation are due before the weekend.
At 18.60 on the daily chart, USD/MXN retains a bullish near-term bias, with spot trading comfortably above the cluster of three simple moving averages (SMAs) around 18.01. Having regained and extended above this gauge of the medium-term trend, the pair appears supported on pullbacks. Meanwhile, the Relative Strength Index (RSI) has retreated from earlier overbought extremes to 54, signalling more balanced, though still constructive, momentum following the recent consolidation.
Initial downside support lies around 18.01 at the cluster of three SMAs. A breach would be required to weaken the current positive technical structure and open the way to further losses. The next significant floor below that area is the horizontal 16.89 level, a more distant but notable zone of demand. Provided the pair remains comfortably above these supports, USD/MXN appears inclined to advance further once fresh resistance levels take shape on the charts.

Among Latin American currencies, the Mexican Peso (MXN) is the most actively traded. Its value largely reflects Mexico's economic performance, central bank policy, foreign investment inflows and remittances from Mexicans living overseas, particularly in the United States. Geopolitical developments can also influence MXN. Nearshoring, for instance, involves companies moving manufacturing operations and supply chains closer to their home countries. It is viewed as a potential driver for the Peso because Mexico is regarded as a key manufacturing hub in the Americas. Oil prices provide another influence on MXN, given Mexico's position as a major exporter of the commodity.
Keeping inflation low and stable is the primary aim of Mexico's central bank, Banxico. It seeks inflation at or near its 3% target, the midpoint of a tolerance range from 2% to 4%, and sets interest rates accordingly. If inflation becomes too high, Banxico seeks to restrain it through rate increases. These raise borrowing costs for households and businesses, dampening demand and wider economic activity. By offering higher yields and making Mexico more attractive to investors, higher interest rates generally support the Mexican Peso (MXN). Lower rates, by contrast, usually weigh on MXN.
Macroeconomic releases help gauge the health of the economy and can influence the valuation of the Mexican Peso (MXN). Robust growth, low unemployment and strong confidence underpin a healthy Mexican economy, supporting MXN. Such conditions attract greater foreign investment and may also prompt the Bank of Mexico (Banxico) to raise interest rates, especially when economic strength coincides with elevated inflation. Weak economic readings, however, are likely to result in MXN depreciation.
The Mexican Peso (MXN), an emerging-market currency, typically performs well when investors favour riskier assets. During these risk-on periods, perceived risks across markets are low, encouraging investors to take on higher-risk investments. In contrast, market turmoil or economic uncertainty usually puts pressure on MXN as investors sell riskier holdings and seek more stable safe-haven assets.
