Eight months into the war between Iran and the United States, diplomacy has produced movement but no settlement. Talks involving Iranian and Qatari officials in Doha ended this week without a breakthrough, although Tehran said contacts were continuing and that revised proposals were circulating. The immediate question is whether negotiations can prevent a new round of US military action after America’s midterm elections—or merely postpone it.
The answer matters far beyond the battlefield. The conflict has disrupted global oil supplies, revived inflation fears and exposed how quickly geopolitical risk can collide with financial markets already strained by high public debt, trade tensions and enormous investment in artificial intelligence.
A narrow diplomatic opening
Qatar has emerged as an intermediary because it maintains relationships with both Washington and Tehran. The talks appear to focus on ending hostilities and managing the issues that made the war durable, but neither side has publicly accepted the other’s core terms. Iranian officials have demanded an end to attacks and security assurances; Washington has continued to keep military pressure available while insisting that diplomacy remains preferable.
That ambiguity is deliberate. For Tehran, negotiations can reduce immediate pressure without requiring capitulation. For President Donald Trump, maintaining the threat of force may be intended to improve the US bargaining position. Yet the same strategy carries a risk: Iranian leaders have warned that renewed attacks would prompt retaliation against US and Israeli targets in neighboring countries, while Trump has declined to rule out further operations after the election.
“Contacts between Iran and the United States to end their eight-month war are continuing,” Iran’s foreign ministry said after the Doha talks, Reuters reported.
The political calendar complicates the diplomacy. Trump has said there will be no new attacks before the US vote, creating an obvious point of uncertainty immediately afterward. China and Russia have opposed renewed military action, but their influence over the negotiations appears limited. The central bargaining problem is therefore not only what each side wants, but whether either government can trust the other to honor a pause once military pressure is reduced.
Why oil is the pressure point
Energy markets have so far absorbed the shock better than some early forecasts suggested. The OECD attributed that resilience to substantial inventories, supplies from outside the Gulf and government support measures. But the cushion is not unlimited. Oil prices fell more than 4% on hopes that the talks could ease supply disruptions, showing how strongly markets are pricing the possibility of diplomacy. Goldman Sachs has warned that Brent crude could reach $140 a barrel in 2027 if Gulf output remains 3.5 million barrels per day below its 2025 average.
That scenario would transmit the conflict into household budgets and central-bank decisions worldwide. Higher fuel and transport costs would raise headline inflation, while weaker real incomes would restrain consumption. Central banks facing renewed price pressure could delay rate cuts or tighten policy, increasing borrowing costs for governments, companies and households.
The OECD projects global growth of 2.9% in 2026 and 3.0% in 2027, down from 3.4% in 2025. Its forecast assumes that energy prices ease next year. A prolonged or expanded war would challenge that assumption, especially if shipping routes, production facilities or Gulf infrastructure came under sustained attack.
The AI boom meets geopolitical risk
The conflict is also testing the narrative that artificial-intelligence investment can carry the world economy through a period of weak productivity and political instability. AI-related spending has helped support production, trade and financial markets, but it depends on cheap and plentiful capital. An oil shock could keep inflation elevated and force central banks to maintain higher interest rates, raising the cost of data-center construction and reducing the value investors assign to long-term technology projects.
Optimists argue that AI investment remains a powerful source of productivity and that diversified energy supplies, inventories and government intervention can contain the damage. Skeptics counter that markets have become concentrated around a small group of technology companies and that heavy capital spending is vulnerable to any rise in financing costs. Reuters has described global markets as already fragile, citing stress in sovereign bonds and emerging-market currencies alongside the risks from wars and trade tensions.
What comes next
Three paths now appear plausible. The first is a limited agreement: a ceasefire, monitored military restraints and further negotiations. That would likely lower oil-risk premiums and give central banks more room to respond to slowing growth. The second is an unstable pause, in which talks continue while both sides prepare for renewed strikes. The third is escalation after the US election, potentially widening attacks and producing a much larger energy shock.
The most important signal will be whether negotiators can turn general promises into verifiable commitments. A durable settlement would require mechanisms for monitoring military activity, clear consequences for violations and enough political cover for both governments to claim that they secured national interests rather than surrendered.
For now, the conflict’s economic impact remains manageable but conditional. The OECD’s relatively resilient outlook depends on inventories, alternative supply and easing tensions. Diplomacy has bought time; it has not removed the underlying risk. The next phase will determine whether that time becomes a pathway to de-escalation or simply the interval before another shock.
