Shippers divert VLCCs via Cape of Good Hope, adding about 14 days to voyages
- Tanker owners are sending some VLCCs around the Cape of Good Hope instead of through Hormuz, as attacks and threats keep Gulf transits dangerously uncertain. - The key number is time: the Cape detour adds roughly 10 to 14 days, while some Gulf war-risk premiums have jumped 4x or more. - That matters because Hormuz is the outlet for a huge share of seaborne crude, so delays quickly turn into higher freight and energy costs.
Oil tankers are taking the long way around Africa because the short way has become a war-risk decision. That sounds like a routing tweak, but it is really a supply-chain shock. A very large crude carrier — the giant ships that move Gulf crude to Asia and beyond — can save time and fuel by going through the Strait of Hormuz. But when owners worry about missiles, drones, crew safety, and insurance, the math flips. That is why some VLCCs are now detouring via the Cape of Good Hope, even though it adds about two weeks to a voyage. (lloydslist.com) ### Why is Hormuz the hard chokepoint? The Strait of Hormuz is narrow, crowded, and unavoidable for most exports coming out of the Persian Gulf. If a ship loads in Saudi Arabia, Iraq, Kuwait, the UAE, or Qatar, there are not many alternate sea exits. So even when the waterway is not formally shut, a credible threat can (lloydslist.com)mned attacks and threats against merchant shipping there, which tells you this is not just market nerves — it is a live security problem. (imo.org) ### What changed for tanker owners? The immediate change is that risk is no longer theoretical. UKMTO incident notices show repeated attacks and security events tied to the wider crisis, and shipping-market reporting says spot tanker rates surged as owners started gaming out whether to transit, wait, or ballast awa(imo.org) kind of move only happens when ships become scarce exactly where cargo still needs to move. (ukmto.org) ### Why go all the way around Africa? Because the Cape route buys distance from the threat zone. It is slower and more expensive, but it reduces exposure to the Gulf and the Strait itself. The extra sailing time is generally put at about 10 to 14 days, depending on the exact origin and destination. For a VLCC, that means more bunker fuel burned, more days tied up on one cargo, and fewer shi(ukmto.org)etour tightens effective fleet supply even if the number of ships in the world has not changed.

Market reporting says war-risk premiums for Gulf transits hit record highs, with some cases quadrupling and some published estimates putting single-voyage cover for a $120 million tanker in the $600,000 to $1.2 million range. That is not a(briefs.co) even when owners can buy the cover, some still stay away because insurance pays money after a loss — it does not protect the crew in real time.

If crude arrives late, refineries adjust runs, traders reshuffle cargoes, and charterers scramble for replacement ships.

UNCTAD has warned that Cape diversions carry broad economic costs and more uncertainty for global trade. (unctad.org) ### Does this mean oil supply is gone? Not necessarily. The barrels can still move — just slower, pricier, and with more friction. That distinction matters. A full physical outage would be a different order of shock.

(lloydslist.com) ### Bottom line The Cape diversion is the shipping market’s way of putting a price on danger. When VLCCs add 10 to 14 days to avoid Hormuz, they are not just burning more fuel — they are shrinking available tanker capacity and pushing up the delivered cost of oil. If the security threat lingers, that extra distance stops looking temporary and starts reshaping trade flows. (briefs.co)
