Systemic Risks of US Naval Blockade in Strait of Hormuz: Energy Geopolitics, Historical Precedents, and Regional Stability

Indigenous and local maritime communities in the Gulf have long relied on the Strait of Hormuz for fishing, trade, and cultural identity, yet their knowledge of ecological and social resilience is excluded from policy discussions. Traditional navigation practices and seasonal rhythms of the strait are dismissed in favor of militarized transit models, erasing centuries of sustainable cohabitation with the marine environment. The blockade threat disrupts these communities’ livelihoods, yet their voices are absent from energy geopolitics.

The Strait of Hormuz has been a flashpoint since the 19th century, when British colonial powers enforced 'gunboat diplomacy' to control Persian Gulf trade routes and oil flows. The 1953 coup against Iran’s democratically elected Prime Minister Mohammad Mossadegh, orchestrated by the US and UK, established a precedent for US intervention to secure oil resources, directly shaping Iran’s nuclear program and regional alliances. The 1980s 'Tanker War' during the Iran-Iraq War demonstrated how blockades escalate into broader conflicts, with global energy markets as collateral damage.

In Iran, the strait is framed as a symbol of national sovereignty and resistance against foreign domination, echoing historical struggles against Portuguese, British, and American interventions. Gulf Cooperation Council states, while allied with the US, also navigate complex internal dynamics where public sentiment often opposes overt militarization, reflecting broader Arab and Muslim worldviews that prioritize stability over hegemonic control. Chinese and Indian perspectives emphasize the strait’s role in their energy security, framing US actions as destabilizing to global supply chains.

The Strait of Hormuz handles ~20% of global oil transit, and a blockade would disrupt supply chains, triggering price spikes and economic instability in energy-dependent economies. Climate models predict that regional conflicts over resources like oil and water will intensify as temperatures rise, exacerbating food and energy insecurity in the Middle East and North Africa. Scientific literature on 'resource curse' dynamics shows that oil-rich regions with high militarization levels experience higher conflict rates and lower human development outcomes.

The strait is a recurring motif in Persian poetry and Gulf folklore, symbolizing both fragility and resilience in the face of external pressures. Artists in the region often depict the strait as a living entity, reflecting its ecological and cultural significance, contrasting with its portrayal as a mere geopolitical tool. Spiritual traditions in the Gulf emphasize the concept of 'amana' (trusteeship), framing the strait as a shared responsibility rather than a contested asset.

A full blockade could trigger a cascade of regional conflicts, including attacks on oil infrastructure, cyber warfare, and proxy battles across the Middle East, with global economic repercussions. Scenario modeling suggests that a prolonged blockade would accelerate the shift toward renewable energy in Europe and Asia, but at the cost of short-term economic disruption and geopolitical fragmentation. Long-term, the crisis could redefine energy transit routes, with pipelines and alternative shipping lanes emerging as new chokepoints.

Low-income laborers in Gulf states, many of whom are migrant workers from South Asia, would bear the brunt of economic fallout from a blockade, facing job losses and food insecurity. Women in the region, who often manage household resources in patriarchal societies, would face increased burdens as prices rise and social services strain. Indigenous communities in the Strait’s coastal regions, such as the Kumzari people in Oman, would see their traditional livelihoods destroyed by militarization and environmental degradation.
