The Mexican peso opened July 13 with a slight drop against the Us Dollar, trading at 17.48 per dollar around 7:40 a.m. in Mexico City after falling 0.08% at the start of the session. The move kept USD/MXN in a tight band between 17.46 and 17.53 pesos, but it was enough to show how quickly the market was reacting to the latest shock from Ormuz.
Janneth Quiroz Zamora said the peso began the day under selling pressure because geopolitical uncertainty remained elevated and demand for emerging-market currencies was weaker. That mattered today because the pressure was not coming from one market alone: the index dollar stood at 100.98 points, up 0.03%, while risk appetite also softened in equities and commodities as investors looked for safety.
The pull on the peso also reflects what happened over the weekend, when Estados Unidos and Irán carried out attacks and the dispute over the Estrecho de Ormuz sharpened. Teherán said the narrow passage had been closed to commercial shipping, while Washington said it remained open under American protection. Those conflicting claims helped keep the market on edge, because the route carries more weight as a source of fear when traders cannot tell whether traffic is restricted or merely threatened.
Kapital Grupo Financiero said confidence among investors and traders deteriorates when the escalation deepens and the messages around Ormuz do not match, because that mismatch feeds speculation about supply cuts. The firm added that the market will keep paying a geopolitical risk premium in oil while the strait operates far below normal, a description that matters operationally because it means shipping is moving with clear disruption, not with the steady flow that usually anchors pricing.
The pressure was visible beyond foreign exchange. This morning, the IPC of the Bolsa Mexicana de Valores was down 0.25% at about 66,330 points, the S&P 500 fell 0.32%, the Nasdaq Composite dropped 1.07%, and the Dow Jones Industrial Average rose 0.32%. That mix points to a market that is not fleeing all risk equally, but is still pricing caution into assets tied to growth and trade.
For now, the peso’s move looks less like a full break and more like a warning: as long as Ormuz stays at the center of conflicting claims, USD/MXN is likely to stay sensitive to every new headline.
