Brent Falls 4.3% to Three-Month Low After US-Iran Hormuz Deal

Brent crude fell 4.3% to $83.57 per barrel on June 15, 2026, its lowest level since March, following the announcement of a 14-point memorandum of understanding (MOU) between the United States and Iran to reopen the Strait of Hormuz on June 19, 2026, according to El Financiero. WTI (West Texas Intermediate) dropped 5.1% to $80.55 per barrel in the same session.

The Strait of Hormuz had been closed since February 28, 2026, driving up crude supply costs for Europe and Asia, whose import chains rely heavily on Persian Gulf flows, according to a report by the Energy Information Administration (EIA) published June 8, 2026. The MOU envisions a formal reopening on June 19, though the repair timeline for key facilities such as the Ras Laffan complex in Qatar keeps a geopolitical premium embedded in crude prices. For Mexico, the transmission channel is indirect: a lower Brent reduces maritime shipping costs, industrial inputs, and imported fuels, easing inflationary pressures on the domestic productive sector and creating room for Banco de México (Banxico) to maneuver on monetary policy.

Market reaction was broad-based: the Mexican peso appreciated to 17.17 per dollar on June 15, 2026, its lowest reading since February 20, 2026, according to El Financiero. Víctor Gómez Ayala, analyst at Finamex, noted that "cheaper oil translates into lower transportation costs, reducing inflationary pressures and giving Banxico room to deepen its rate-cutting cycle." Gabriela Siller, head of analysis at Banco Base, said the agreement "would contribute to easing inflationary pressures" in the Mexican economy. Equity markets across Asia and Europe posted gains in the same session.

The key indicator to watch is the formal signing of the MOU on June 19, 2026, and the repair schedule at the Ras Laffan complex. That timeline will determine whether crude price normalization holds and whether Banco de México has room to accelerate its interest rate-cutting cycle.
