Significant shift toward US-Iran rapprochement under Trump administration, with Iran's new supreme leader Mojtaba Khamenei asserting independent authority while maintaining hardline rhetoric. US leverage increased through port blockade lifting, but Iranian skepticism and delayed negotiations suggest limited trust. Regional powers (Gulf allies, Israel) face uncertainty over US-Iran realignment.
Similar to 1979 post-revolution period when US-Iran relations collapsed; current thaw parallels 2015 JCPOA negotiations but with greater uncertainty given leadership transition in Iran and Trump's previous JCPOA withdrawal.

Consumers face uncertain oil price trajectory; potential for lower energy costs if deal stabilizes, but risk of price spikes if negotiations collapse. Delayed implementation increases near-term volatility in fuel and heating costs.
Governments may need to adjust sanctions regimes, defense budgets, and trade policies. Central banks could face inflation management challenges depending on oil market stability. Potential for renewed diplomatic engagement frameworks or contingency planning for deal failure.
