overview
The interim U.S.–Iran memorandum of understanding signed in June remains suspended as a formal ceasefire but still provides the principal diplomatic framework for negotiations. Since late July, however, the conflict has entered another volatile phase in which military escalation and diplomacy have proceeded simultaneously. Although President Donald Trump has repeatedly threatened renewed strikes against Iranian targets during this past week, he announced on 2 August that the United States would suspend planned military action after Iran and several regional states requested additional time to conclude a rapid agreement focused on reopening the Strait of Hormuz and addressing concerns over Iran’s nuclear program. Trump stated that Israel had agreed to support this approach, although Israeli officials simultaneously reiterated that they would continue to act independently against any future Iranian nuclear or ballistic missile activity.
Diplomatic efforts have therefore shifted toward securing a limited operational agreement centered on restoring maritime navigation rather than reviving the broader June memorandum. Oman remains the principal mediator and is promoting a regional maritime framework governing transit through the Strait of Hormuz. However, significant differences remain. Iran is seeking greater control over navigation through the Strait, while the United States and European partners remain committed to preserving freedom of navigation. Saudi Arabia has supported
deescalation, with Crown Prince Mohammed bin Salman emphasizing dialogue during discussions with President Trump.
Despite these diplomatic efforts, the regional security environment remains fragile. The reported drone strike targeting LNG infrastructure near Egypt’s Damietta coast highlighted the lingering volatility of the regional security environment and the vulnerability of critical energy infrastructure, although Iran denied responsibility for the attack. Houthi attacks have persisted against commercial shipping and Saudi-linked maritime interests in the Red Sea, although the group has publicly denied reports that it intends to impose transit fees on vessels using the Bab el-Mandeb Strait. Maritime security incidents have also resumed off the coast of Oman, including attacks against commercial tankers, reinforcing the lasting risks facing regional shipping despite ongoing diplomatic negotiations.
Rather than moving toward a comprehensive settlement, the conflict has evolved into a broader contest over regional maritime security, energy infrastructure and strategic deterrence. Direct U.S.–Iran military operations remain paused, but proxy activity, attacks on commercial infrastructure and competing diplomatic initiatives are keeping the risk of renewed escalation elevated.
Market Response:
Energy markets remain highly sensitive to developments surrounding the Strait of Hormuz. Brent crude rose approximately 24% during July as repeated disruptions to Gulf shipping, limited tanker movements and uncertainty surrounding negotiations constrained global energy markets. Although President Trump’s announcement that planned U.S. strikes would be suspended helped ease immediate concerns, oil prices remain substantially above pre-conflict levels as markets still price in significant geopolitical risk.
Commercial shipping through the Strait of Hormuz remains well below normal volumes despite tentative signs of recovery. Qatar has resumed limited LNG exports through the Strait, while , the UAE’s energy company, has begun repositioning vessels for future cargo loadings, suggesting that energy companies expect a gradual improvement in navigational conditions. Nevertheless, QatarEnergy has extended force majeure declarations through September, insurance premiums remain elevated and shipping companies remain highly cautious. Simultaneously, ongoing Houthi threats against Bab el-Mandeb and recent attacks against vessels near Oman have reinforced pressure on alternative maritime routes.
Financial markets still distinguish between the resilience of Gulf economies and the persistent security risks surrounding regional trade. While Saudi Arabia and the UAE have demonstrated strong macroeconomic fundamentals, investors are pricing heightened geopolitical risk across energy, logistics, aviation and financial services, with expectations increasingly centred on a prolonged period of intermittent military tension rather than either a rapid peace settlement or sustained conventional conflict.
Regional Implications
The conflict has increasingly become a contest over maritime access and regional infrastructure rather than solely Iran’s nuclear programme. Negotiations remain focused on restoring safe navigation through the Strait of Hormuz, while attacks on energy infrastructure and commercial shipping demonstrate that wider regional risks remain substantial.
Saudi Arabia has demonsrated considerable resilience despite the disruption to Gulf shipping. The IMF has maintained a broadly positive outlook for the Saudi economy, projecting growth to accelerate despite regional instability and highlighting the Kingdom’s diversified logistics infrastructure, strong banking sector and ability to reroute significant oil exports through the East–West Pipeline to Yanbu. At the same time, Saudi Arabia is strengthening alternative maritime routes through the Red Sea, including expanding shipping services at Jeddah Islamic Port and pursuing broader logistics diversification under Vision 2030.
The Kingdom has also intensified efforts to strengthen regional maritime security, proposing a multinational Red Sea maritime coalition while investing in missile defence, logistics resilience and strategic infrastructure. Nevertheless, recent Houthi attacks against Saudi-linked infrastructure and drone activity targeting neighbouring states demonstrate that Saudi Arabia’s exposure has shifted geographically rather than diminished.
The UAE remains highly exposed to disruptions affecting global trade, financial services and maritime commerce. Regulators are advancing reforms despite the security environment, while Abu Dhabi and Dubai maintain their focus on financial services, real estate and logistics. However, prolonged disruptions to Gulf shipping and continued uncertainty surrounding Hormuz remain significant risks for regional trade flows.
Across the GCC, governments are accelerating investment in supply-chain resilience, cybersecurity, alternative export routes, maritime security, strategic reserves and critical infrastructure protection while maintaining diplomatic engagement aimed at preventing broader regional escalation.
What to watch
During the 60-day negotiation period, the following indicators will provide the clearest signals as to whether the memorandum evolves into a durable settlement or remains a temporary stabilization mechanism:
Whether the current pause in direct U.S.–Iran military operations holds or renewed strikes are authorised.
Progress toward a limited agreement on reopening the Strait of Hormuz and restoring commercial shipping.
Omani mediation efforts and any evolution of proposals governing maritime navigation.
Commercial shipping volumes, insurance costs and LNG exports through the Strait of Hormuz.
Further Houthi attacks against commercial shipping, Red Sea infrastructure or Saudi energy assets.
Additional attacks against regional energy infrastructure, including facilities outside the Gulf.
Oil prices, freight costs and investor sentiment across GCC markets.
Israeli policy regarding unilateral military action against Iranian nuclear or missile programmes.
Public messaging from Washington, Tehran and Gulf governments regarding negotiations and regional de-escalation.
Although diplomatic engagement has intensified, the conflict remains characterised by a fragile military pause alongside continued proxy attacks, maritime insecurity and competing strategic objectives. The near-term outlook therefore remains one of conditional de-escalation rather than durable peace, with negotiations increasingly focused on restoring freedom of navigation and protecting regional energy infrastructure while the risk of renewed escalation remains high.
