• The International Atomic Energy Agency (IAEA) warns that the risk of Iran developing nuclear weapons is now greater than before the Trump administration's maximum pressure campaign began, citing advances in enrichment and reduced verification.
  • Iran now possesses substantial quantities of 60% enriched uranium, nearing weapons-grade, while IAEA access and monitoring have eroded, heightening concerns about a potential breakout.
  • Diplomatic efforts remain stalled, raising the risk of escalation and potential military confrontation, with implications for global energy markets and regional stability.

The IAEA has issued a stark assessment that the nuclear threat from Iran is more acute today than at the start of President Trump's first term, according to people familiar with the matter. The agency's latest confidential reports indicate that Tehran's enriched uranium stockpile, particularly at 60% purity—a short technical step from weapons-grade—has grown significantly since 2025, despite intensified US sanctions.

“The window for diplomacy is narrowing,” a senior IAEA official said, speaking on condition of anonymity. “Without a deal, the risk of miscalculation or accidental escalation is higher than it has been in years.”

The erosion of the 2015 nuclear deal’s verification regime has been a key factor. Iran has restricted IAEA access to key sites and disabled monitoring equipment, leaving the agency unable to fully account for all nuclear materials and activities. This has amplified fears that Iran could rapidly assemble a nuclear device if it chose to.

International efforts to revive negotiations have faltered. Indirect talks between Washington and Tehran, mediated by European and Gulf states, broke down in late 2025 over disagreements on enrichment limits and sanctions relief. The IAEA has called for restraint but acknowledged that its ability to provide assurance is “diminished.”

The implications are already being felt in global oil markets. Brent crude prices have fluctuated on every headline about Iranian progress, with traders pricing in a risk premium for potential supply disruptions in the Persian Gulf. Analysts at several major investment banks have flagged the Iran situation as a top geopolitical risk for 2026.

“The market is on edge,” said a commodities strategist at a European bank. “Any military strike on Iranian nuclear facilities could send oil prices skyrocketing.”

Regional neighbors are also bracing for fallout. Gulf Arab states, while wary of Iran, have quietly urged Washington to pursue a diplomatic off-ramp to avoid a broader conflict. Israel, meanwhile, has reiterated its willingness to act militarily if it deems diplomacy has failed.

The IAEA's warning marks a sobering milestone. Critics of the Trump administration’s policy argue that the “maximum pressure” approach has backfired, pushing Iran toward the very outcome it was meant to prevent. Supporters counter that the deal was flawed and that only renewed pressure can bring Iran back to the table.

For now, the risk remains elevated. The IAEA continues to urge all parties to return to talks, but as stockpiles grow and trust erodes, the path to a peaceful resolution appears increasingly uncertain.
