mexicos peso experienced a modest decline Monday following teh release of bi-weekly inflation data, underscoring the currency’s sensitivity to economic signals.The peso’s movement comes as the Bank of Mexico assesses its monetary policy in the face of evolving price pressures, wiht general inflation edging above expectations while core inflation remained stable. Investors are closely watching these trends as they gauge the potential for future interest rate adjustments that could impact the peso’s value against the U.S. dollar, currently trading at 18.99 pesos at Banamex branches[[1]].
The Mexican peso experienced a slight depreciation on Monday, November 21, 2025, following the release of inflation data for the first half of November. The peso’s performance reflects ongoing sensitivity to economic indicators as the Bank of Mexico (Banxico) weighs future monetary policy decisions.
According to data released, Mexico’s general inflation rate rose to 0.47% during the first two weeks of November, exceeding the consensus expectation of 0.42%. However, core inflation remained subdued, increasing by only 0.04%, falling below forecasts. This mixed reading presents a complex picture for policymakers.
The Banco de México (Banxico) reported that the peso weakened by 0.15%, or 0.03 cents, against the previous day’s close, closing at 18.51 pesos per U.S. dollar. The peso’s reaction suggests investors are carefully assessing the implications of the inflation data for future interest rate adjustments.
Felipe Mendoza, CEO of IMB Capital Quants, noted that the inflation figures did not trigger a significant reaction in the currency markets. “The peso closed with a slight depreciation, more associated with a technical adjustment than a deterioration of fundamentals,” Mendoza said.
Dollar Exchange Rate Today
As of today, November 21, 2025, the U.S. dollar is being offered at 18.99 pesos at Banamex bank branches, according to reported data. This retail rate reflects the broader market movement following the inflation release.
Looking ahead, Mendoza anticipates the exchange rate will likely remain within a limited range, influenced by upcoming economic data releases from the United States, communication from Banxico, and any new trade-related announcements from the Trump administration.
“As long as these elements remain stable, the level around 18.40–18.60 will continue to act as a natural tactical equilibrium zone for the Mexican peso,” Mendoza indicated.
Meanwhile, the U.S. dollar index (dxy), which measures the dollar’s strength against a basket of six major currencies, fell 0.02% to 100.17 points. The Bloomberg dollar index (bbdxy) rose 0.03% to 1,226.81 points.
