title: Dataset Repository for "Analysis of maritime geopolitics on early 2026: The Red Sea Factor"

description: This comprehensive research report examines the cascading geopolitical, economic, and environmental impacts of the Red Sea crisis on global maritime trade, supply chains, and sustainable development. The analysis traces the Houthi-led disruption of one of the world's most critical shipping chokepoints (the Bab el-Mandeb Strait and Red Sea corridor) from late 2023 through early 2026, documenting its transformative effect on global route choices, freight rates, and trade architecture.

Research Focus

The report investigates three interconnected maritime systems reshaping global trade:

 The Red Sea Crisis (2023–2026): Houthi attacks on commercial vessels have reduced Red Sea and Bab el-Mandeb traffic to 35–40% of pre-crisis levels, forcing diversion via the Cape of Good Hope and adding 6,000–11,000 nautical miles to Asia–Europe voyages. Despite ceasefire arrangements in 2025, traffic recovery remains structurally limited, indicating a durable reconfiguration driven by risk perception and insurance market dynamics rather than formal conflict cessation.

 Emerging Polar Maritime Frontiers: Climate-driven Arctic Sea Route (NSR) ice loss is progressively enabling navigation across northern passages, offering 30–40% distance reductions on some Europe–Northeast Asia trades. Simultaneously, Southern Ocean and Antarctic routes are acquiring geopolitical relevance due to resource competition and great-power positioning, despite limited near-term commercial viability.

 Global Maritime System Fragmentation: The confluence of these dynamics signals erosion of post-Cold War assumptions about open, neutral sea lanes. A "dual-route equilibrium" is emerging wherein risk prioritization over efficiency creates differentiated security architectures and regionally controlled corridors, fragmenting the traditionally unified global maritime system.

Key Findings

 Economic Impact: Red Sea rerouting has increased shipping costs by up to US$1 million per voyage (fuel alone) and contributed to elevated freight rates affecting global supply chains.

 Sustainability Paradox: Risk-averse route choices increase aggregate carbon emissions and environmental pressure, while polar route development shifts ecological burdens to the planet's most fragile ecosystems.

 Development Vulnerability: Small Island Developing States (SIDS) and Least Developed Countries (LDCs) face disproportionate exposure to maritime disruptions, with 25–30% of household incomes spent on maritime-dependent food imports in some regions.

 Governance Gaps: The Red Sea crisis exposes critical weaknesses in global maritime governance frameworks (IMO, UNCLOS) and the absence of binding international mechanisms for Arctic shipping regulation, particularly regarding black carbon emissions.

 Non-State Actor Influence: Houthi forces demonstrate how actors with minimal conventional military capacity, embedded in regional proxy conflicts, can exert outsized influence over global trade flows affecting food security, energy markets, and development trajectories across continents.
