Iran to open nuclear sites to IAEA under 14-point deal

Tehran will grant the IAEA access to its nuclear facilities for the first time in years, marking a breakthrough in US-Iran nuclear diplomacy.

Iran will invite the International Atomic Energy Agency to inspect its nuclear facilities and locate enriched uranium stockpiles, US Special Envoy Steve Witkoff told lawmakers June 18, the most concrete step yet under a 14-point interim peace deal.

"It is good that the memorandum is there. Now the technical work starts," Rafael Grossi, director general of the IAEA, told reporters in Geneva. "Now it is for us to sit down with our American and Iranian colleagues and start formulating concrete steps."

The 14-point agreement, signed digitally by President Donald Trump and Iranian President Masoud Pezeshkian in English and Farsi, extends a ceasefire announced in April by 60 days, including in Lebanon. Under the accord, Iran can retain its enriched uranium but must downblend it to lower concentrations, according to the memorandum text. The IAEA will supervise and verify compliance.

The inspection commitment removes the single biggest obstacle to a broader nuclear deal — verification. If implemented, it could unlock sanctions relief worth tens of billions of dollars for Iran's economy and reduce the risk premium embedded in crude oil prices, which have carried a $5-to-$8 per barrel geopolitical risk adder since the US-Israel strikes on Iran in February triggered a regional war.

Verification Remains the Core Challenge

Grossi cautioned that the magnitude of the IAEA's work will be determined by the final provisions of the agreement. Technical talks in Vienna will seek to translate the general principles into concrete inspection protocols, including access to military sites where Iran has previously been accused of conducting nuclear-related activities. The IAEA's last comprehensive inspection report on Iran, published in 2023, identified undeclared uranium particles at two locations — sites Iran had refused to open to inspectors.

The last time Iran agreed to enhanced IAEA access was under the 2015 Joint Comprehensive Plan of Action, which limited enrichment to 3.67% purity. After the US withdrew from that deal in 2018, Iran expanded enrichment to 60% purity — a short technical step from weapons-grade 90%. The IAEA estimates Iran's stockpile of enriched uranium at more than 30 times the JCPOA limit, according to its quarterly reports.

Market Implications Depend on Implementation

For oil markets, the deal's impact hinges on whether sanctions relief materializes. Iran currently exports about 1.5 million barrels per day of crude, much of it through opaque channels to Chinese independent refiners. Formal sanctions relief could add 500,000 to 1 million bpd to global supply within six months, according to tanker-tracking data, potentially weighing on Brent crude prices that have traded between $72 and $82 a barrel since the February escalation.

Gold, which rallied to record highs above $3,200 an ounce during the conflict, could see safe-haven flows unwind if the inspection process proceeds smoothly. The CBOE Volatility Index, which spiked to 28 during the February strikes, has already declined to the 16-18 range as ceasefire talks progressed.

The 60-day extension provides a window for negotiations on a final truce. Failure to reach a comprehensive agreement would risk a return to the military confrontation that erupted in February, when US and Israeli strikes on Iranian nuclear and military facilities sparked a regional war that sent oil above $95 a barrel and gold to all-time highs.
