Five Reasons the US-Iran Ceasefire Could Still Fall Apart Before June 19

AI Market Analysis

The tenuous US‑Iran ceasefire MOU introduces heightened geopolitical risk that could keep oil markets on edge. Any breach or Israeli escalation may tighten supply expectations, especially if the Strait of Hormuz remains partially blocked, potentially supporting higher crude prices and boosting energy sector equities. Conversely, if diplomatic channels hold, the prospect of gradual sanctions relief for Iran could ease some pressure, allowing oil prices to stabilize or even dip modestly.

Investors may see risk‑off sentiment spill into safe‑haven assets such as the US dollar and Treasury yields, while regional equities—particularly Israeli defense stocks and Iranian‑linked commodities—could experience volatility. Currency pairs involving the rial and the shekel may also react to shifting expectations of sanctions relief or renewed conflict. Overall, market participants are likely to adopt a cautious stance, pricing in both upside risk to oil and downside risk to risk‑sensitive assets.

Five Reasons the US-Iran Ceasefire Could Still Fall Apart Before June 19

The US-Iran ceasefire Memorandum of Understanding signed on June 14, 2026, has generated significant optimism across diplomatic circles and financial markets. But experts who have closely tracked US-Iran relations caution that the path from an initial MOU to a durable ceasefire is littered with historical precedents of failed agreements. Here are five key risks that could unravel the deal before the formal signing ceremony in Switzerland on June 19.

The Zero Trust Problem: The foundational challenge is that US-Iran mutual trust is effectively at zero. Decades of broken agreements, unilateral sanctions, proxy conflicts, and assassination operations have created an environment where each side assumes bad faith. The MOU’s phased structure — releasing economic benefits only as Iran meets verifiable benchmarks — was designed to manage this, but it also creates constant opportunities for dispute about whether benchmarks have been met. Any perceived violation in the first week could provide a pretext for either side to withdraw.

Israel’s Veto Power: As demonstrated by Israel’s Lebanon operations on June 13–14, Israeli military action can directly threaten the diplomatic environment. Israel has not endorsed the ceasefire framework, and senior Israeli officials have reportedly described the MOU as “dangerously naive” regarding Iran’s nuclear intentions. Israel retains both the capability and political will to conduct operations that could trigger Iranian responses.

Domestic Politics in Both Capitals: In Washington, hardline voices have already begun raising questions about whether the deal gives Iran too much economic relief too quickly. Congressional pushback could limit the President’s ability to implement sanctions relief. In Tehran, Revolutionary Guard commanders who have built institutional power through the conflict economy may resist a peace framework that diminishes their operational roles.

Unrealistic Implementation Timeline: Reopening the Strait of Hormuz requires coordinated demining operations, IMO route safety certification, insurance market normalization, and diplomatic deconfliction with all naval forces in the region — a process that realistically takes months, not days. If Iranian leaders observe the Strait remaining effectively closed while they maintain a ceasefire, pressure to abandon the framework will grow quickly.

Third-Party Wildcard Events: The region contains multiple potential disruptors: Houthi forces in Yemen, which maintain their own command structure; Shia militia groups in Iraq; and miscalculation risks in any direct US-Iran naval encounter in the Gulf. A single incident — even if accidental — could be exploited by hardliners on both sides to declare the ceasefire null and void.
