Temporary U.S. sanctions waivers on Russian and Iranian oil have acted less like a structural reset and more like a pressure valve for a market shocked by the Iran war. They briefly restored supply confidence, softened the immediate risk of a deeper crude and products squeeze, and bought time for refiners, traders and buyers to reposition—but they did not remove the underlying geopolitical premium, especially as the waivers now approach expiry.

The Iran war has moved from a geopolitical event to an industrial market shock. In a matter of days, it disrupted oil, gas, fertilizer and petrochemical flows, then pushed the consequences deep into agriculture, manufacturing and global trade. For decision makers, the key issue is no longer whether prices moved. It is how fast the shock cascaded through supply chains, which products were hit first, and how long the disruption may last.

What began as a shock to oil and gas markets has rapidly morphed into a broader supply chain crisis. About a third of the world’s traded urea and up to half of global sulphur exports are linked to Gulf producers and seaborne routes that are now severely constrained. Qatar alone normally supplies roughly one‑third of global helium, a niche market with almost no spare capacity elsewhere. The result is a cascade of second‑order effects that are hitting Asia, Africa, Europe and L

Asian refiners, power utilities, and aviation hubs are being squeezed by the Hormuz crisis, which has choked off traditional Gulf export routes just as regional demand recovers. In this context, reliable FOB supply out of Jurong and other Asian ports —paired with CIF cargoes on an ASWP basis— offers a concrete way for traders and end‑users to secure EN590, Jet A1, and other refined products without waiting for geopolitics to normalize.

Since early 2022, the Russia–Ukraine war and the escalating Iran–Israel confrontation have combined into a twin shock that has redrawn the global energy map. Together they have fractured long‑standing trade routes, birthed parallel market systems, and injected structural volatility into pricing, logistics, and policy.

The Trans‑Caspian International Transport Route (TITR) –the Middle Corridor– is emerging from the sidelines as a strategic, if imperfect, alternative for both containerized goods and selected energy flows between Asia and Europe. Initially framed as a workaround to war‑related risks in the Black Sea and the Red Sea, the Middle Corridor is now being stress‑tested by an unprecedented combination of container diversion, fuel trade rerouting and geopolitical pressure.

The EU is being squeezed between its long-term strategy to phase out Russian energy and short-term pressure to keep fuel prices under control amid war-driven volatility and supply disruptions. At the same time, Washington is moving in the opposite direction, with President Donald Trump signaling a partial easing of oil sanctions on Russia to cool prices, while Brussels publicly rejects any relaxation of its own measures.

For petroleum markets, “Middle East risk” is not a headline—it’s a transmission mechanism. When conflict intensifies around the Persian Gulf and its maritime chokepoints, prices don’t move only on barrels lost; they move on barrels that might not move, ships that won’t sail, and insurance that won’t clear.

The escalation of conflict involving Iran and its neighbors has turned the Strait of Hormuz into a high‑risk chokepoint for global energy flows, with up to 15 million b/d of Gulf crude and products potentially at risk of disruption. Oil prices have already jumped sharply, with Brent moving from the low‑70s to well above 80–90 USD/bbl in early March, while European gas and LNG benchmarks have spiked on fears over Qatari exports.

Crude oil, refined products and LNG reach global markets through a complex network of pipelines, tanker routes and strategic chokepoints. This article maps the world's primary energy transport corridors, their capacities, vulnerabilities and trading implications. Understanding how barrels and cargoes move—or get rerouted—directly impacts spreads, cracks and compliance strategies in today's sanctioned, volatile markets.
