The Mexican peso lost ground against the US dollar on Friday, July 17, as renewed uncertainty surrounding US-Iran relations weighed on emerging-market currencies.
The greenback approached the 18-peso threshold in bank markets, driven by a lack of progress in negotiations aimed at ending hostilities in the Middle East.
This move marks a reversal from earlier in the week, when the peso had strengthened slightly on July 9 as traders assessed the immediate impact of the conflict.
The recent shift underscores how quickly sentiment can pivot when diplomatic channels stall, with investors returning to the safety of the dollar amid fears of prolonged instability.
The broader context reflects a sustained trend of dollar strength against a basket of peers, fueled by concerns over supply chain disruptions and rising energy costs linked to the escalating military conflict.
As the US intensifies its military posture, the risk premium embedded in emerging-market assets continues to expand, putting pressure on the peso and other regional currencies.
