Mexican peso stabilizes as US dollar falls on Fed rate hold and Middle East flare

Mexican peso US dollar Federal Reserve rate decision Middle East tensions oil price

The US dollar index slipped about 0.1% in late July 2026, trading near 101.3‑101.5 points, extending a roughly 8% year‑to‑date decline and reaching its lowest level in four years against a basket of currencies. The Mexican peso hovered between 17.44 and 17.49 per dollar on 29 July, showing a modest depreciation of around 0.3‑0.4% after three sessions of gains.

The Federal Reserve left its benchmark rate unchanged in the 3.50‑3.75 % range, with a 9‑to‑3 vote, prompting analysts to look ahead to a possible 25‑basis‑point hike in September. Meanwhile, renewed US‑Saudi strikes on Iran‑backed militia groups in Iraq drove oil prices up more than six percent, adding inflation pressure and risk‑aversion in markets.

Donald Trump’s comments that he is not interested in renewing the US‑Mexico‑Canada trade pact (T‑MEC) added further uncertainty for the peso. On the broader market, US consumer confidence fell to 90.8 points in July, and North Sea Brent crude dropped about 4.8% to $84.09 a barrel, while equities showed mixed performance.
