Iran offered to halt its uranium enrichment program for up to five years in talks with the United States in Pakistan over the weekend, but the proposal was rejected by Washington, according to officials briefed on the discussions.
The U.S. delegation, led by Vice President JD Vance, insisted on a 20-year suspension instead, underscoring how wide the gap remains between the two sides and reducing the likelihood of a swift diplomatic breakthrough.
Us conditions: no nuclear weapons, open strait
Speaking earlier in the day, Vance did not directly confirm the five-year offer but repeated that Washington’s conditions were unchanged.
He said any agreement must ensure Tehran fully abandons nuclear weapons development and reopens the Strait of Hormuz, framing both as non-negotiable requirements for the U.S. administration.
The Islamabad talks form part of broader efforts to calm tensions and explore terms for a more stable regional security framework after months of indirect contacts and failed mediation attempts.
Nuclear timeline at core of future talks
The length of any enrichment suspension and guarantees of Iranian compliance are expected to remain central in upcoming negotiations.
The sharp difference between the proposed five-year cap and the U.S. demand for 20 years indicates that prolonged bargaining is likely, extending geopolitical uncertainty and complicating planning for governments and markets.
Global oil flows exposed to prolonged uncertainty
The stalemate carries direct implications for energy security because U.S. conditions link nuclear de-escalation to the status of the Strait of Hormuz, the world’s key oil transit chokepoint.
Data from the U.S. Energy Information Administration show that roughly one-fifth of global daily petroleum flows — about 21 million barrels per day — passes through the strait. Historically, any disruption there has driven immediate, sharp increases in crude prices, feeding directly into headline inflation in major economies.
Market impact: volatility and risk aversion
With negotiations at an impasse and rhetoric still hardening, financial markets are likely to remain highly sensitive to any news of progress or breakdown.
Signs of increased military activity or sharper language from Washington or Tehran would likely trigger broad risk-off moves, pressuring equities and riskier credit while supporting perceived havens such as the dollar and U.S. Treasuries.
For traders, the environment favors close monitoring of sudden price swings and policy headlines. Maintaining higher-than-usual liquidity and defining clear exit levels on positions may help manage downside risk in the event of an abrupt escalation.
What to watch next
Market participants will be watching for:
- official readouts or leaks from mediating officials in Pakistan
- statements from Washington and Tehran that might hint at softening or hardening positions
- reports of unusual naval deployments or incidents near the Persian Gulf and the Strait of Hormuz
In the near term, tone and messaging from both capitals are set to be the main drivers of short-term directional bias across energy and broader asset markets.
