US–Iran 21-hour Talks Fail: What will be the market impact? Anil Singhvi, Ajay Bagga explain

A high-stakes 21-hour negotiation between Iran and the United States ended without an agreement in Islamabad, dealing a setback to already fragile diplomatic efforts and raising fresh concerns over global markets, oil prices and geopolitical stability. US Vice-President JD Vance confirmed that despite “substantive discussions”, no breakthrough could be reached, as both sides remained far apart on critical issues including nuclear commitments and control over the Strait of Hormuz.

The development comes at a time when global markets were hoping for at least a temporary easing of tensions. With negotiations collapsing after nearly a full day of talks, experts now warn that the fallout could be immediate - particularly for energy prices and equity markets worldwide.

Why did the 21-hour Iran–US talks fail?

According to officials and expert analysis, the talks were weighed down by deep-rooted mistrust and structural flaws in how negotiations were conducted.

Market expert Ajay Bagga said the meeting was “designed for failure”, pointing to the absence of key global stakeholders such as European nations, China and Russia. He argued that a bilateral format was inadequate to bridge a geopolitical gap that has persisted for nearly five decades.

Bagga also questioned the choice of mediation, noting that Pakistan lacked the strategic leverage to influence either side meaningfully. Without broader international participation, the talks struggled to create the pressure or incentives required for compromise.

On the ground, the disagreements were substantial - ranging from Iran’s nuclear programme to shipping security in the Strait of Hormuz and financial conditions tied to sanctions relief.

What did the US and Iran say after the stalemate?

Speaking after the talks, US Vice-President JD Vance said Washington had presented its “final and best offer”, but Iran refused to accept key conditions, particularly around nuclear restrictions.

He stressed that while the US had been “flexible”, Tehran did not agree to assurances that it would not pursue nuclear weapons capabilities.

Iranian state media, however, blamed what it called “excessive demands” from Washington, suggesting that the US position made it impossible to reach even a preliminary framework.

Meanwhile, US President Donald Trump has signalled a more assertive stance following the failed talks, raising concerns about potential escalation in the region.

Market impact: Will Nifty and global equities react?

Zee Business Managing Editor Anil Singhvi believes the market had already priced in low expectations, but the outright failure of talks could still trigger a near-term reaction.

He warned that Indian markets could see a 1–2 per cent dip in the Nifty index, especially if crude oil prices spike on fears of supply disruption.

“The concern is not just the failure of talks, but what follows next,” Singhvi noted, adding that any escalation in the Strait of Hormuz - a key global oil transit route - could sharply push up energy prices and inflation.

Bagga echoed similar concerns, saying markets had become “complacent” and were expecting at least a temporary ceasefire or de-escalation. That expectation now stands broken.

Four global ‘timelines’ shaping the conflict

Market veteran Ajay Bagga outlined a complex geopolitical matrix driving the crisis, highlighting four competing priorities:

• The US, under Donald Trump, is under pressure to deliver quick results amid rising inflation and political challenges
• Iran is attempting to prolong tensions to gain strategic leverage
• Gulf nations want stability but not a stronger Iran emerging as a regional superpower
• Israel remains opposed to any quick compromise, citing existential security concerns

This divergence makes a quick resolution unlikely, especially through bilateral talks.

What happens next?

Despite the breakdown, some experts believe diplomacy is not entirely over. Backchannel communication and technical-level discussions may continue.

However, the risk of escalation - particularly in the Strait of Hormuz has increased. Any disruption in this critical oil route could have immediate global consequences, including higher fuel prices and pressure on economies already facing slowdown risks.

Bagga stressed that a multilateral negotiation involving Europe, China and Russia is the only viable path forward. Without it, he warned, repeated failures could deepen instability.
