Six Saudi Tankers Take the 56 Day Route Around Africa; Cost Per Voyage Rises by 2 to 2.5 Million Dollars (Monday, 3 August 2026)

<p>Maritime intelligence firm Windward reported on Monday, 3 August 2026 that the voyage of one Saudi tanker now sailing around the Cape of Good Hope in southern Africa will take 56 days. The same route, until recently, took 24 days through the Bab el-Mandeb strait. Satellite imagery and vessel tracking data show that at least six Saudi flagged tankers have shifted away from Bab el-Mandeb to the long way around Africa, and the cost of each voyage has risen by 2 to 2.5 million dollars.</p> <p>The point of the day lies in the contrast between two numbers. On the same day that the physical route for Saudi crude became more than twice as long, Brent crude stood at 83 dollars and 47 cents as of 13:08 Tehran time on Monday, 3 August 2026, down 5.34 percent from the previous day. The paper market priced in the resumption of talks; the transport map moved the other way.</p> <h2>Background</h2> <p>Understanding the 56 day figure takes two steps back. With the Strait of Hormuz closed, Saudi Arabia shifted the bulk of its oil exports to the East to West pipeline running to the port of Yanbu on the Red Sea, and that route effectively became the only remaining way to move Saudi crude to Asian markets. Yanbu was the replacement for Hormuz, not an extra option.</p> <p>The second step came this week. With the Ansarallah movement threatening vessels linked to Saudi Arabia in response to the blockade of Yemen, the southern exit of the Red Sea, the Bab el-Mandeb strait, became unsafe as well. In a note dated 28 July 2026, Windward described the situation as two closed corridors: Hormuz and Bab el-Mandeb both effectively shut to tanker traffic at the same time. Reuters had earlier reported that three tankers carrying Saudi crude made U turns in the Red Sea after an Ansarallah warning. A New York Times analysis, circulated on 1 August 2026, reported Saudi officials acknowledging that they cannot counter the naval blockade.</p> <p>For a sense of scale, a time comparison helps. Brent crude had risen roughly 20 percent in the month to 31 July 2026, driven by precisely these route risks. Today the same barrel gave back 5.34 percent in a single session, while none of the physical bottlenecks has actually opened.</p> <h2>The numbers</h2> <table> <thead><tr><th>Metric</th><th>Value</th><th>Date and source</th></tr></thead> <tbody> <tr><td>Voyage time via Bab el-Mandeb</td><td>24 days</td><td>Windward, 3 August 2026</td></tr> <tr><td>Voyage time via Cape of Good Hope</td><td>56 days</td><td>Windward, 3 August 2026</td></tr> <tr><td>Added cost per voyage</td><td>2 to 2.5 million dollars</td><td>Windward, 3 August 2026</td></tr> <tr><td>Tankers that rerouted</td><td>at least 6</td><td>Satellite imagery, 3 August 2026</td></tr> <tr><td>Vessel transits through Bab el-Mandeb (Sunday)</td><td>18</td><td>Kpler, 3 August 2026</td></tr> <tr><td>Same figure on Friday and Saturday</td><td>28 and 27</td><td>Kpler, 3 August 2026</td></tr> <tr><td>Brent crude</td><td>83.47 dollars, down 5.34 percent</td><td>3 August 2026, 13:08 Tehran</td></tr> </tbody> </table> <p>The drop in transits from 28 vessels on Friday to 18 on Sunday, a fall of about 36 percent in two days, shows how fast shipowners react to risk. Set that number beside the <a href="/en/prices/brent">Brent crude price</a> and the gap between the paper market and the physical market becomes clear.</p> <h2>Drivers</h2> <p>The first driver was the closure of Hormuz, which reduced Saudi export options to a single corridor. The second is the threat to that replacement corridor. But the mechanism connecting the two to price is more than simply a longer route.</p> <p>In shipping economics what matters is ton miles, not barrel counts alone. When the same cargo occupies a tanker for 56 days instead of 24, the effective capacity of the global fleet shrinks even if not a single barrel of production is lost. Put simply, moving the same volume of oil now requires more than twice the ships. The result shows up in freight rates and war risk insurance premiums, not necessarily in production statistics. The figure of 2 to 2.5 million dollars in added cost per voyage puts a number on that effect.</p> <p>The third driver is risk itself. Kpler data show part of the fleet clearing the route before any incident occurs, meaning that the threat alone, without leading to an attack, removes capacity from the market.</p> <h2>The transmission channel to Iran's markets</h2> <p>This is not only a Saudi story. Three channels connect it to Iranian markets.</p> <p>First, the global oil price. Iran's export revenue and the earnings of refining and petrochemical names on the Tehran Stock Exchange ride on that number. A 5.34 percent drop in Brent on a day when physical logistics deteriorated means the risk premium is being priced off diplomatic headlines rather than off the map.</p> <p>Second, freight rates and war risk insurance. Corridor economics are the same for Iranian cargo; higher freight eventually reaches the landed cost of imported goods and from there domestic inflation.</p> <p>Third, the transit lesson. Iran knows this logic from the other side: a route is an asset that never runs out but can be blocked. Our earlier coverage of Iran's transit volumes and of the geopolitical risk premium is in the <a href="/en/articles">Sahmino articles archive</a>.</p> <h2>Outlook</h2> <p>This section is not a forecast and only reports the positions of the sources. Maritime analytics firm Kpler has said Saudi oil export flows will fall further in the coming weeks unless the Bab el-Mandeb blockade ends. On the other side, CNN, citing shipping sources, reported that between three and five million barrels per day of crude still leave the Persian Gulf via a southern route close to the coast of Oman, meaning the flow has not been cut so much as made slower and more expensive. The distinction between a flow being cut and a flow becoming expensive is exactly what the paper market overlooked today.</p> <p>At the same time the diplomatic track is open: the market today priced in the resumption of talks. If the political knot loosens, the 56 day figure will disappear faster than it appeared; if it does not, its cost accumulates in freight rates. Scheduled events that bear on this are listed in the <a href="/en/calendar">Sahmino calendar</a>.</p> <h2>Conclusion</h2> <p>Two markets said two different things today, and only one of them was reading the map. The paper market made Brent 5.34 percent cheaper, while the physical market stretched the route for Saudi crude from 24 days to 56 days and added 2 to 2.5 million dollars to the cost of each voyage. It matters because the risk premium that came out of the price did not come out of the logistical reality. The one thing to remember: while both corridors stay closed, cheaper oil on the screen does not mean easier oil on the water.</p> <h2>What to watch</h2> <ul> <li>The daily count of transits through Bab el-Mandeb in vessel tracking data; a return to the 27 to 28 range would signal the route normalising.</li> <li>The number of tankers choosing the Cape of Good Hope route; a rise above six would mean the problem is deepening.</li> <li>Freight rates and war risk insurance premiums on Persian Gulf and Red Sea routes.</li> <li>The path of <a href="/en/prices/brent">Brent crude</a> in the days after the talks, as a test of whether the risk premium returns.</li> <li>Saudi oil export figures in the weeks ahead, as a test of Kpler's claim.</li> </ul> <p>This report describes published data only and contains no buy or sell recommendation.</p>
