• Trump urges Iran to accept nuclear deal terms, warning of consequences without agreement.
  • Talks in late May 2026 remain fluid, with disagreements over enrichment limits and verification.
  • Market volatility persists as oil prices react to diplomatic uncertainty.

Trump's Ultimatum

Former President Donald Trump, leading U.S. negotiations, issued a stark warning to Iran on Thursday: "They should sign the deal, or there will be consequences." The statement came as talks in Vienna enter a critical phase, with both sides haggling over the terms of a renewed nuclear agreement. According to people familiar with the matter, Trump is insisting on strict conditions, including the dismantling of Iran's nuclear program and a cap on enrichment levels.

Negotiation Hurdles

The back-and-forth has been intense. U.S. negotiators are pushing for stringent monitoring and verification mechanisms, while Iran has drawn red lines on enrichment limits and sanctions relief. "The next few weeks are decisive," a diplomat involved in the talks said. Without a deal, the region could face heightened tensions, including potential snapback sanctions or military escalation. Oil markets have already priced in some risk, with Brent crude hovering near $85 a barrel.

Market and Regional Implications

A breakthrough could ease sanctions and stabilize the Middle East, offering relief to energy markets. However, skepticism remains. "Iran's willingness to accept robust inspections is an open question," a former IAEA official commented. The talks are also being watched closely by Gulf states, which seek assurances on regional security. For now, the clock is ticking.
