YouTube warns of Hormuz 'tsunami effect'

Oil is the obvious story here. But the real problem is bigger than oil. The Strait of Hormuz is a tiny waterway that handles a huge share of global energy and commodity flows, and when traffic through it seizes up, the shock runs straight into shipping, insurance, food costs and public finances. That is the “tsunami effect” people are talking about — not one dramatic wave, but a chain of knock-on hits that starts in tankers and ends in household budgets. (unctad.org) ### Why is Hormuz such a big deal? The strait is a narrow passage between Iran and Oman, but it carries outsized global volume. In 2025, nearly 20 million barrels a day of oil moved through it, plus a big chunk of LNG exports from Qatar and the UAE. There are some b(unctad.org)ound it like a traffic app. (iea.org) ### What actually changed this spring? The important change is that this stopped being a theoretical risk. UNCTAD says ship transits through the strait dropped from an average of 129 a day in February to just 6 a day in March after the regional escalation that began on February 28, 2026. By April, (iea.org)beyond energy markets into trade, logistics and finance. (unctad.org) ### Why doesn’t the damage stop at crude prices? Because shipping costs are layered. First comes the commodity price. Then come tanker rates, marine fuel, delays, rerouting, port congestion and insurance. UNCTAD flagged all of those early, and that is the part many (unctad.org)nventory and keep enough stock on hand in case the next vessel is late. (unctad.org) ### Where does insurance fit in? Insurance is the hidden amplifier. Once war-risk cover gets repriced or pulled, ships may still be physically able to sail, but the economics break. Reports from late April said premiums that were around 0.25% of hull value before th(unctad.org)per is not the same thing as restoring normal trade. (weforum.org) ### Why do poorer countries get hit first? Because they have less room to absorb any of this. UNCTAD’s April assessment tied the Hormuz disruption to inflation, weaker currencies, higher borrowing costs and tighter import capacity in developing economies.

Turns out Hormuz is not just an oil corridor. UNCTAD says it also carries meaningful volumes of chemicals and fertilizers, and even a smaller share of container and dry-bulk traffic can matter if the goods are essentia(unctad.org)ergy chokepoint becomes a grocery-bill story. (unctad.org) ### Can producers just use other routes? Only partly. Saudi Arabia and the UAE have some pipeline capacity outside the strait, but the IEA puts total alternative crude export capacity at roughly 3.5 to 5.5 million barrels a day — far short of normal Hormuz flows. Co(unctad.org)cancel the shock. (iea.org) ### What is the bottom line? The “tsunami effect” framing is useful because it captures the sequence. First the chokepoint tightens. Then energy prices jump. Then insurance and freight costs spike. Then vulnerable countries start rationing dollars, trimming imports or taking on more debt. By the t(iea.org)unctad.org)
