For centuries, maritime chokepoints have dictated the rhythm of global commerce. Today, the Strait of Hormuz\u2014a waterway through which nearly 20% of global oil supply once flowed\u2014has become a case study in how geopolitical rupture can be quantified, tracked, and anticipated in near real-time. The latest data from S&P Global Market Intelligence and Commodities at Sea (CAS) offers more than just a snapshot of shipping lanes; it provides a masterclass in the new cartography of global trade, where transparency has become the most valuable currency.<\/p>\n
The Digital Lens on Physical Reality<\/strong><\/p>\n S&P Global’s Commodities at Sea service represents a paradigm shift in how we understand global supply chains. By providing vessel-by-vessel cargo intelligence with intra-day updates, CAS transforms raw data into actionable intelligence that reveals the hidden architecture of global trade. This is not merely a tracking tool; it is a fundamental analysis engine that captures the nuanced interplay between geopolitical events and market dynamics.<\/p>\n Consider the recent crisis in the Strait of Hormuz. Before the escalation in February 2026, over 100 vessels carrying approximately 20 million barrels of crude and refined products transited the Strait daily. By late May, CAS data showed this traffic had collapsed to an average of just 11 vessels per day\u2014a more than 90% decline that left over 800 vessels stranded. The data revealed something even more telling: even as discussions about reopening emerged, “commercial reopening” remained elusive. US-sanctioned vessels accounted for 45% of all transits in March and 29% in April, underscoring the extent to which conventional commercial operators had withdrawn. The data doesn’t just show where ships are; it reveals confidence, or the lack thereof, in global trade routes.<\/p>\n The Shadow Fleet and Structural Deficit<\/strong><\/p>\n Perhaps the most revealing insight from recent S&P Global analysis concerns the transformation of the global tanker fleet itself. As geopolitical tensions have reshaped trade flows, a shadow fleet comprising 15-20% of global tanker capacity has emerged, creating what analysts describe as a “structural deficit for mainstream charterers”. This is not a temporary disruption but a fundamental restructuring of maritime logistics.<\/p>\n The VLCC segment provides a compelling illustration of these dynamics. Despite concerns about global economic headwinds, S&P data shows VLCC tonne-miles increased by 4.8% month-on-month and 6.8% year-on-year, representing the highest employment levels this year. This seemingly paradoxical strength reflects how altered trade flows\u2014particularly Europe’s pivot away from Russian shipments toward sources like India and China\u2014have increased shipping distances and vessel utilization. The data captures a market contorting itself to accommodate geopolitical realities.<\/p>\n The implications for fleet dynamics are profound. With fewer newbuild VLCC orders and an aging fleet increasingly involved in sanctioned trades, the supply-demand equation for mainstream charterers has fundamentally shifted. Traditional forecasting models, which rely on simple fleet growth metrics, no longer apply in this fragmented landscape.<\/p>\n The Fragmentation of Global Commodity Flows<\/strong><\/p>\n Beyond crude oil, the CAS data reveals a broader fragmentation of commodity flows. Floating storage patterns in Southeast Asia, for instance, tell a complex story about how sanctioned cargoes navigate market pressures. According to S&P data, floating storage of crude in Southeast Asian waters declined from record levels at end-2025, led by a 53% draw-down of Iranian barrels. Yet the nuance is critical: some of this drawdown reflected not consumption but the movement of unsold Iranian cargoes into Chinese storage, with intermediaries advancing payments to facilitate discharge.<\/p>\n This intricate choreography of sanctioned trade, tracked through vessel movements and storage patterns, reveals the resilience of global commodity markets\u2014and their growing sophistication. The CAS data captures not just flows but the financial engineering that enables them to continue despite sanctions and disruptions.<\/p>\n Meanwhile, Chinese refiners have demonstrated remarkable adaptability, sourcing crude from diverse alternatives including Russian, Brazilian, West African, and US grades. This diversification, tracked through vessel movements and origin-destination patterns, has enabled China to maintain import volumes even as traditional supply routes have been disrupted.<\/p>\n The Fragmented Fleet Below the Surface<\/strong><\/p>\n The dry bulk market offers another lens into these structural changes. S&P Global’s fleet supply analysis reveals a critical divergence beneath the surface of overall fleet growth. While net fleet growth remained relatively stable at 3.1% year-over-year in 2025, the segmentation by vessel size tells a different story. Capesize fleet growth is projected at just 2% for 2026, while Panamax and Supramax segments are expected to grow at approximately 5%. This divergence suggests significantly different supply pressures and rate volatility profiles across segments\u2014a nuance that matters immensely for charterers, traders, and investors.<\/p>\n The newbuilding contraction adds another layer of complexity. At 31.6 million Dwt in 2025, newbuilding contracting was down 44% year-over-year. This slowdown, if sustained, will limit delivery volumes beyond 2027 and potentially tighten supply in an already constrained market.<\/p>\n A New Era of Market Intelligence<\/strong><\/p>\n What makes S&P Global’s Commodities at Sea service transformative is its capacity to transform raw data into strategic intelligence. The platform covers all major liquid and dry bulk commodities, from crude oil and refined products to coal, iron ore, agricultural products, and fertilizers. It provides cross-commodity visibility that allows traders, analysts, and portfolio managers to identify signals that shape price and timing decisions.<\/p>\n The recent analysis of the VLCC market illustrates this value. S&P data showed that laden VLCCs now represent more than 45% of the total fleet globally, an unprecedented level since 2020. This metric, combined with data on vessel speeds, ballast trends, and congestion patterns, provides a comprehensive picture of market health that goes far beyond simple freight rate analysis.<\/p>\n Conclusion: Transparency as a Strategic Asset<\/strong><\/p>\n The data from S&P Global Market Intelligence and Commodities at Sea paints a picture of a world in transition\u2014one where traditional trade routes are disrupted, new supply chains are being forged, and the distinction between mainstream and shadow commerce has blurred. In this environment, the ability to track vessel movements, anticipate cargo arrivals, and understand the complex interplay between geopolitics and logistics has become an essential strategic asset.<\/p>\n The Strait of Hormuz crisis demonstrates that even the most critical chokepoints can be disrupted, and that recovery\u2014when it comes\u2014will be measured not in days but in months. As Rahul Kapoor noted, “Markets differentiate between a technical re-opening of Hormuz and a commercial re-opening,” which requires restored confidence, eased insurance, and safe passage. The data from CAS will be essential in tracking when\u2014and whether\u2014these conditions are met.<\/p>\n In the new era of global trade, visibility is power. The ability to see beyond headlines, to track the movement of commodities vessel by vessel, and to understand the structural transformations beneath the surface of markets, is what will separate the prepared from the surprised. S&P Global’s Commodities at Sea service provides not just data, but the analytical framework to navigate a world where the old maps no longer apply.<\/p>\n Andrew Mwangura is a Mombasa based Public Intellectual and Maritime Affairs Analyst<\/strong><\/em><\/p>\n For centuries, maritime chokepoints have dictated the rhythm of global commerce.
