The long way round

Six Saudi supertankers have given up on both chokepoints and are sailing around Africa, adding up to three weeks to every voyage. They did not switch off their transponders to do it. That single detail tells you what this war has done to the sea: there are three ways to answer a permission regime now, and only one of them is available to those who can afford it.

First, the night's ledger

Six very large crude carriers owned by Bahri, Saudi Arabia's national shipping line, turned away from the Bab al-Mandeb and set course south through the Indian Ocean for the Cape of Good Hope. Ship-tracking services recorded the first destination changes on 30 July: the Ghinah and the Laynah signalling Durban, the Burqan cycling through Durban, Algoa Bay and Port Elizabeth, the Dilam and the Hazm initially signalling Gibraltar with the Hazm later switching to Durban, and the Salam also indicating South Africa. Two trade sources told Reuters the Cape was chosen with the security situation in mind. The detour adds between two and three weeks to a voyage.

At the same time Saudi crude is moving north instead of south — shuttled from Yanbu to Ain Sukhna, pumped across Egypt through the Suez-Mediterranean pipeline, and loaded again at Sidi Kerir on the Mediterranean coast, where at least eight empty supertankers have been signalling their arrival. On the diplomatic track, the corridor talks described in yesterday's edition continued without a published text.

They did not go dark

Here is the detail that matters, and it corrects something this letter argued only yesterday. MarineTraffic notes that these tankers made no attempt to disable their transponders. They broadcast the change of destination openly, in a week when this desk had just finished describing a Gulf fleet learning that invisibility was the only position that offended neither enforcer.

So the correction is this: there are not two responses to a permission regime. There are three. A ship can apply to Iran's transit authority and accept a permit, with the sanctions exposure that carries. It can switch off its transponder and try to pass unrecorded. Or it can leave the system altogether — sail three weeks further, visibly, lawfully, and pay for the privilege in time and fuel.

The third option is not a strategy. It is a purchase. And the price is set at a level only an owner who controls the ship, the cargo and the pipeline behind it can meet.

Desk inference: that changes what the sorting mechanism actually is. Through May and June the question was whose flag a vessel flew and who owned the cargo. Now it is whether the operator can absorb twenty-five days. A national oil company with its own fleet can. A single-ship owner on a spot charter, carrying someone else's cargo against a delivery window, cannot — and is left choosing between a permit and a switched-off transponder. Saudi Arabia has not found a way around the toll. It has bought an exemption from the choice, which is a different thing, and one most of the world's tonnage cannot afford.

What the detour costs everybody else

The bill does not stay with the buyer. A voyage lengthened by three weeks removes that vessel from the world's available fleet for three weeks; enough such voyages and the pool of ships chasing every other cargo tightens, and freight rates rise on routes with no connection to this war. Saudi Arabia is also paying to run its barrels through a second country's pipeline rather than its own sea lane, which converts a one-off security problem into a standing transit cost.

The strategic reading follows from that. Yesterday's edition argued that the corridor being negotiated is a temporary licensing regime with an Iranian administrator. The Bahri decision is what a government does when it has read that same proposal and concluded it will not be relying on it. Riyadh is not waiting for the corridor to open. It is building a route that does not need one.

Meanwhile, off the war desk

The outbreak we said nobody was covering, and then stopped covering. On 30 May this letter ran a special edition arguing that a vaccine-less Ebola outbreak closing on one of East Africa's largest cities was receiving roughly two per cent of the coverage the Iran story commanded. It ran as a standing item on 2, 3 and 6 June. It has not appeared here since. That was a failure of exactly the kind the edition was written to criticise, and it is worth stating plainly before the numbers.

They are grim. On 21 July the Democratic Republic of the Congo reported 2,473 confirmed cases and 999 deaths. By 3 August the figures were 3,874 confirmed cases and 1,751 deaths, with 717 patients hospitalised in isolation — a rise of roughly three-quarters in the death toll in thirteen days. Ituri province accounts for 3,375 cases and 1,417 deaths across 28 of its 36 health zones; North Kivu has 426 cases and 290 deaths. By the end of July it had become the fastest-growing Ebola outbreak on record, and it is now the second-largest ever counted.

The reason it is not being stopped the way recent outbreaks were is a matter of virology rather than will. This is Bundibugyo virus, not the Zaire species against which the licensed vaccines and therapeutics were developed. There is no approved vaccine and no specific treatment for it; early supportive care is what exists. Bundibugyo had caused two prior outbreaks in history — 149 cases in Uganda in 2007, 52 in the DRC in 2012 — so the present emergency is more than twenty times larger than anything previously seen from this pathogen.

One thing did work. Uganda declared its outbreak over on 28 July after 74 days, with 20 confirmed cases, two deaths and no community transmission at all — every case traced to importation or to contacts and health workers linked to it, in a capital city of more than three million. Contact tracing and isolation contained a haemorrhagic fever in Kampala without a vaccine. The same tools are being applied across the border against a caseload nearly two hundred times larger, in provinces where 47 of 140 health zones are affected and where armed conflict has been displacing the population for years. The United States has restricted entry for travellers recently in the DRC since May, with the current order due to lapse in the coming days.

The blind spot

Blind spot

The assumption that a vehicle knows where it is, and that others can know too, is quietly becoming contested — and it has now killed people. In May a medical transport aircraft operated by Trans Aero MedEvac flew from Roswell into a New Mexico mountainside at 9,950 feet, killing both pilots and both flight nurses. Federal investigators have since confirmed that the aircraft's satellite navigation failed because the military was jamming the signal across the area at the time. The sequence in the preliminary report is careful: the crew reported losing navigation, the controller vectored them for an instrument approach, the controller contacted the military and had the jammers switched off, and then — after the crew said they had the airport in sight and would land visually — cleared the military to resume. Three other aircraft reported interference in the same period. The pilots' association says this appears to be the first fatal accident in which such interference was a factor, and that crew reports of jamming have risen sharply in recent years while the notices warning of it have been inconsistently distributed.

Two experienced aviators told the Associated Press the loss of satellite navigation should not by itself bring down an aircraft — if you can see the runway, you can see the mountain. The cause will not be determined until the final report next year, and this letter does not assign one. What is established is narrower and still significant: a state jammed navigation over its own territory, civil aircraft lost the signal, and four people died in the aftermath.

Now hold that against the last fortnight of this letter. In the Gulf, tankers are switching off their transponders because being seen has become the dangerous condition. Over New Mexico, aircraft lost their position because a state chose to deny the signal in a training area. One is concealment and the other is denial, and they are converging on the same outcome: a world in which knowing where things are can no longer be assumed. Satellite navigation and automatic identification were built as public goods, unglamorous and universal, on the premise that everyone benefits from everyone being locatable. That premise is now being withdrawn from two directions at once — by operators who no longer wish to be found, and by states that no longer wish others to find their way.

Desk inference: there is also a governance question here that is separate from the crash, and the evidence for it is firmer. In February the Pentagon permitted Customs and Border Protection to use an experimental anti-drone laser near the southern border; a person familiar with the matter told the Associated Press it was deployed without coordinating with the aviation regulator, which then shut the airspace to protect flights — and it was used despite a meeting being scheduled later that same month between the two agencies to discuss precisely that technology. Nobody was hurt. But an enforcement priority overrode an aviation-safety process, and the process found out afterwards. That is a documented coordination failure, and it is a fair thing to hold in mind while the crash investigation runs. It is not evidence about the crash, and we do not present it as such.

Scoring — what we called, and what happened

Each call starts as our confidence (a %). Once the outcome is known we grade it out of 10, where 6 or more is a hit. Dates link to the original prediction.

MissThe escalation branch fires — a strike on Kharg, Pickaxe Mountain or infrastructure (26%) 27 Jul 4 / 10

The mechanism was right and the branch came within a telephone call of firing: the energy campaign was real, reached the President's desk with Kharg among the targets under consideration, and was cancelled on 1 August after Gulf leaders intervened. But it did not happen, and a forecast is graded on what occurred. Four rather than three because the reasoning held and the weight was correctly kept low.

Four ways the next window breaks

  • 38%The Cape route widens. Further Gulf-origin or Saudi-linked tankers are reported routing around the Cape of Good Hope rather than through either chokepoint. Closes 13 August. Falsifier: the six return to the Bab al-Mandeb with no further diversions reported.
  • 24%Riyadh says so out loud. Bahri or the Saudi government publicly confirms a change of routing policy, rather than leaving it to be inferred from tracking data. Closes 13 August.
  • 24%The border stays shut. The United States renews or extends its entry restrictions on travellers recently in the Democratic Republic of the Congo before the current order lapses. Closes 13 August. Falsifier: the order is allowed to expire without replacement.
  • 14%The regulator moves on jamming. An aviation regulator or safety authority issues a new advisory, directive or rule change concerning notification of satellite-navigation interference. Closes 13 August. A preliminary accident report alone does not satisfy this.
  • Method note. Load-bearing claims trace to sources fetched and read today: the European Centre for Disease Prevention and Control for the outbreak's July figures, the provincial breakdown, the Ugandan case history and the imported cases in Europe; and the Australian Broadcasting Corporation's report, compiled by Maddie Nixon with wire material, for the New Mexico crash, the preliminary investigation findings, the pilots' association comments, the aviators' assessments and the February border-laser episode — supplied to this desk in full text after the site blocked automated retrieval, and named here so readers know the standard it met. The early-August outbreak figures, the Bahri vessel movements and destinations, the Sidi Kerir loadings and the trade sources' explanation are drawn from ship-tracking services, Reuters, Bloomberg and MarineTraffic as reported, read in indexed excerpt rather than fetched in full; the vessel movements are corroborated across five independent outlets. The characterisation of the outbreak as the fastest-growing on record and second-largest ever is as reported by outbreak trackers and is a claim about a moving total. No cause has been determined for the New Mexico crash and none is asserted here; the February coordination failure is reported as a separate documented event and is expressly not offered as evidence about the crash. Passages marked as desk inference are our reading of incentives and documented behaviour, not reported fact. Post-publication developments are forecast, not reported. The approach, the six coverage domains and our scoring record — graded daily and reviewed each month — are set out on the About page. No financial advice is expressed or implied.
