News of a potential agreement between the United States and Iran marks a substantial shift in the Middle Eastern risk landscape, although overly optimistic interpretations should be avoided. The understanding is currently framed as a memorandum of understanding rather than a definitive agreement — a distinction that matters, because the terms remain unclear and the root causes of tension remain entirely unresolved: from Iran’s nuclear program to enriched uranium stockpiles, missile capabilities, and support provided to regional militias.
THE RELEVANCE OF THE AGREEMENT
The immediate relevance of the agreement therefore concerns less a definitive conclusion to geopolitical risk in the region, and much more the concrete possibility that it can contain the most economically disruptive channel of the entire conflict: the constraints imposed on energy flows through the Strait of Hormuz.
WHAT WILL CHANGE IN THE STRAIT OF HORMUZ?
The Strait represents the main transmission channel of the conflict on international financial markets, due to the central role it plays in global oil and natural gas trade. Navigation restrictions imposed in recent months have amplified energy price volatility, worsened inflation expectations, and significantly contributed to a reassessment of risk on interest rates globally.
However, the reopening of the Strait is unlikely to be immediate. Navigation corridors may require clearance and securing operations, while updating operational protocols, redefining insurance premiums, and the gradual rebuilding of risk appetite among industry operators will inevitably affect the timing of recovery. In this sense, the distinction between formal reopening and effective normalization of flows remains central to correctly assessing market prospects in the coming months.
ENERGY FLOWS
Should energy flows normalize in a credible and lasting way, the macroeconomic implications could prove very significant. A sustained drop in oil and gas prices would reduce pressure on overall inflation, mitigate second-round effects on consumer prices, and favor a progressively less restrictive monetary policy stance by major central banks.
These institutions already face the challenge of balancing still persistent inflation with a progressively slowing growth momentum, in a context complicated by the legacy of rate hike cycles in recent years. A credible reduction in energy prices would ease pressure for further tightening and could re-anchor market expectations around a monetary policy path more favorable to growth. Conversely, any new disruption in supplies would likely restore upward pressures on inflation, interest rates, and risk premiums.
THE INITIAL MARKET RESPONSE
The initial market response has been overall constructive, reflecting reduced risk on energy prices, a lower tail risk on the inflation front, and the prospect of a potentially less aggressive monetary policy trajectory than scenarios considered more likely until recently. These dynamics are favorable both for equities and credit, particularly insofar as investors can refocus on still resilient growth fundamentals and corporate earnings expectations which, overall, remain positive.
However, the durability of this reassessment will depend on the concrete implementation of the agreement, and there are reasons for caution on this front. The understanding remains incomplete in its essential elements, the operational reopening of the Strait will require time and resources, and the risk of escalation cannot be said to be eliminated. The market movement recorded in recent sessions should therefore be read as a relief rally, to be evaluated prudently while awaiting clearer and more consolidated evidence of a lasting normalization of energy flows and a structural reduction in geopolitical risk premiums.
The proposed agreement is potentially significant precisely because it targets the main macro transmission mechanism of the conflict, namely the disruption of energy supply and its repercussions on global prices. If implemented credibly and sustained over time, it could reduce inflation risk, decrease the likelihood of further monetary policy tightening, and help build a more favorable environment for risky assets.
However, this is not a complete reset of the previous situation, and it would be a mistake to interpret it as such. The risk to energy security has been deeply reassessed, the structural vulnerability of global supply chains has emerged clearly, and geopolitical risk premiums are unlikely to dissolve quickly. Portfolio positioning should therefore make a clear distinction between short-term relief, already partly priced in current valuations, and a lasting improvement in fundamentals, which still requires concrete proof that the agreement can withstand the implementation phase and reliably and stably restore energy flows in the region.
