US-Iran Deal Reshapes Middle East: Iran Gains, Rivals Alarmed

A provisional agreement signed between the United States and the Islamic Republic of Iran, marking the first such step by leaders of both countries since the 1979 Iranian Islamic Revolution, has opened a new chapter in the Middle East. This memorandum of understanding, signed by US President Donald Trump and Iranian President Masoud Pezeshkian on the sidelines of the G7 Summit in Versailles, has the potential to fundamentally alter geopolitical balances by ending a three-month conflict. While hailed by its proponents as the “deal of the century,” the accord has become a source of deep concern for Iran's regional adversaries, including Israel and Gulf states.

The 14-point agreement extends a ceasefire by 60 days, including in Lebanon, to allow negotiations for a permanent settlement and address sensitive issues such as Iran's nuclear program. Key provisions of the deal include Iran's commitment to dilute its stockpile of highly enriched uranium under the supervision of the International Atomic Energy Agency (IAEA). Furthermore, the lifting of US-backed sanctions on Iran and immediately allowing Iran to freely sell its oil stands out as a significant economic gain for Tehran. The reopening of the Strait of Hormuz for free navigation is also a critical point of the agreement.

This development has elicited diverse reactions among regional actors. Lebanese commentator Sarkis Naoum described the agreement as a “grand bargain with no turning back” for Washington and Tehran, while Israeli analyst Danny Citrinowicz characterized it as a strategic “catastrophe.” Citrinowicz stated that the deal failed to meet any of Israel's core demands, such as curbs on Iran's missile programs or proxies, and effectively legitimized and strengthened Iran. Sources from Gulf states also indicated that the deal erodes confidence in US protection and solidifies Iran as an enduring regional force.

The market impact of the agreement was swift and pronounced. Following President Trump's announcement, oil prices experienced sharp declines, while global stock markets reached record highs. The full reopening of the Strait of Hormuz, in particular, alleviated concerns over global energy supply, putting downward pressure on oil prices. During the three-month conflict preceding the agreement, oil prices had surged, financial markets had become apprehensive, and inflation had risen.

Examining the broader economic and political context of the agreement, this step signifies a notable retreat in US strategy in the region and a strengthening of Iran's regional position. Washington sought to alleviate pressure on the US economy, which faced rising oil prices and inflation during the conflict. The agreement also includes a commitment by the US and regional partners to develop a plan for Iran's reconstruction and economic development, totaling at least US$300 billion, to compensate for economic losses incurred by Iran due to the war.

Looking ahead, the 60-day negotiation period to finalize the agreement is of critical importance. During this period, challenging issues such as the future of Iran's nuclear program, the complete lifting of sanctions, and regional security concerns will be addressed. Analysts suggest that the agreement remains fragile and a full consensus may take time. However, the strong incentives for both the US and Iran to avoid a broader conflict enhance the chances of successful negotiations.
