U.S. and Iran Announce Provisional Deal Lifting Oil Sanctions and Reopening Hormuz

The United States and Iran announced on June 17, 2026, a provisional agreement establishing the lifting of oil sanctions on Iran and the reopening of the Strait of Hormuz, with the official signing scheduled for June 19 in Switzerland. West Texas Intermediate (WTI) crude fell 5.8% on June 16, settling at $76.05 per barrel, according to El Universal.

The deal closes a conflict that, per El Universal data, began on February 28, 2026, and kept Hormuz transit restricted for more than 100 days. Under terms reported by AP, Iran regains immediate access to oil markets and receives financial concessions in hard currency, while the United States committed to a phased rollback of sanctions in place since 2018. The agreement redraws the use of energy sanctions as a foreign policy instrument: the possibility of negotiating their removal in a matter of weeks reshapes the strategic calculus for actors who had until now treated them as a durable lever. For Mexico, which exports crude oil and imports natural gas, the recalibration of prices and flows in the Persian Gulf carries direct implications for international benchmark markets.

Analyst Enrique Quintana, writing in El Financiero, cautions that a formal reopening does not mean immediate normalization: demining operations may take 40 to 50 days, and insurance premiums for Hormuz transit have climbed to between 1% and 8% of cargo value (3 to 8 million dollars per voyage). The International Monetary Fund (IMF) has lowered its global growth forecast to 3.1% from 3.4% and raised its inflation projection to 4.4% as a direct consequence of the conflict. For OPEC+, in which Mexico participates as an observer producer, the return of Iranian crude to the market forces a reassessment of production quota strategy. Qatar lost 17% of its LNG export capacity and Kuwait requires three to four months to recover, Quintana notes.

The outstanding chapter is Iran's nuclear program, which was left outside the scope of the provisional deal. The June 19 signing in Switzerland will define the final timelines. If negotiations on the nuclear component break down, Quintana warns that a reactivation of the strait closure remains a credible risk.
