US sanctions deepen maritime blockade amid diplomatic thaw: How structural rivalry eclipses regional trade resilience

Indigenous maritime knowledge in the Persian Gulf—rooted in pearl diving, dhow navigation, and seasonal trade rhythms—has sustained coastal communities for millennia, yet is erased by state-centric narratives that frame trade solely through geopolitical lenses. Traditional navigation techniques, such as reading monsoon patterns or celestial cues, remain critical for small-scale fishermen navigating sanctioned waters, but are dismissed as 'informal' or 'illegal.' The blockade disrupts these knowledge systems, forcing communities to rely on riskier, state-sanctioned routes that increase fatalities and ecological damage.

The US sanctions regime against Iran is the longest-running in modern history, beginning with the 1979 hostage crisis and intensifying with the 1995 executive order banning Iranian oil imports, which set a precedent for extraterritorial sanctions. Historical parallels include the 1917 British blockade of Germany during WWI, which starved civilian populations and fueled black markets, or the 1980s US embargo on Nicaragua, which devastated rural economies while enriching Contra-linked smugglers. Each case reveals how sanctions, framed as 'leverage,' often entrench black markets and empower non-state actors, undermining stated diplomatic goals.

Cross-culturally, maritime trade disruptions are framed differently: in West Africa, *diaspora* traders use *harambee* networks to bypass state controls, while in Southeast Asia, Chinese *guanxi* relationships facilitate informal trade despite sanctions. In the Caribbean, *contrabando* economies thrive on state failures, with traders like those in Haiti or Cuba adapting to US embargoes through creative logistical networks. These systems highlight how marginalised communities globally develop parallel economies to survive state violence, often with greater efficiency than formal channels.

Scientifically, sanctions disrupt supply chains in ways that increase fuel consumption and pollution as ships reroute through longer, less efficient paths, raising CO2 emissions by an estimated 15-20% in sanctioned regions. Studies on embargo impacts (e.g., UNCTAD’s 2022 report on Iran) show that trade disruptions correlate with increased child mortality, reduced educational attainment, and higher rates of informal employment. The US Treasury’s own data reveals that sanctions often fail to achieve stated goals, with only 12% of target regimes changing behavior within five years, while 88% adapt through black markets or alternative alliances.

Artistically, the blockade has inspired works like Iranian filmmaker Jafar Panahi’s *Offside* (2006), which critiques state control over mobility, or the poetry of Forugh Farrokhzad, who mourns the erasure of individual agency under sanctions. Spiritually, the concept of *taqwa* (God-consciousness) in Islam frames sanctions as tests of resilience, while in Hindu traditions, the *yajna* (sacrificial offering) of trade goods to deities mirrors the communal sharing of scarce resources. These perspectives reframe sanctions not as geopolitical tools but as moral and existential challenges to human dignity.

Future modelling suggests that without multilateral enforcement, sanctions will increasingly fragment global trade into regional blocs, with Iran deepening ties with Russia, China, and India to bypass US dominance. Scenario planning indicates that climate-induced migration and resource scarcity will exacerbate maritime conflicts, making trade routes like the Strait of Hormuz more volatile. Technological solutions, such as blockchain-based trade verification, could reduce reliance on US-dominated SWIFT systems, but require international cooperation to avoid becoming new tools of exclusion.

Marginalised voices include Iranian women-led cooperatives like *Zan-Omid* (Women’s Hope), which produce handicrafts for export despite sanctions, or Yemeni fishermen whose boats are confiscated by Saudi-led coalitions enforcing the blockade. In India, small traders in Mumbai’s *Crawford Market* face delays of up to 6 months for Iranian imports, while in Oman, port workers report increased child labor as families adapt to lost income. These communities, often invisible in geopolitical analyses, bear the brunt of sanctions while elites in Washington, Tehran, and Riyadh negotiate power.
