The US dollar strengthened modestly on August 25, 2026, as new US sanctions targeting Iran’s oil exports and financial institutions triggered a flight to safety, while rising Treasury yields added support. The Mexican peso came under pressure even after domestic data showed annual inflation cooling, underscoring how geopolitical shocks can overpower improving emerging-market fundamentals.
Mexico’s INEGI reported a slower annual inflation rate, driven by lower agricultural and energy prices, though core inflation remained sticky. That gives Banco de Mexico more room to consider rate cuts later this year, but policymakers are likely to stay cautious amid external risks and a firmer dollar. Meanwhile, the US dollar index edged higher as investors weighed the impact of sanctions on global energy supplies and inflation, which could keep Federal Reserve policy tighter for longer.
Traders are now watching key dollar index resistance and support levels, upcoming US economic data, and Federal Reserve speeches for direction. Commodity currencies tied to oil may see divergent moves if crude prices spike, while broad risk assets including cryptocurrencies could face headwinds from a stronger dollar and higher yields.
