The shift to dark operations has shattered data consistency among the three major tracking firms:
| Data source | Yanbu estimate (week of Aug 3) | Change from prior week |
|---|---|---|
| Vortexa | 2.38 million bpd | Down from 2.71 million bpd |
| Kpler | 1.78 million bpd | Down sharply from 4.04 million bpd |
| AXSMarine | Significant drop | Visible loadings down at least 30% |
As Reuters noted, these widely differing export estimates — used by the IEA, OPEC, and traders — underscore how dark tanker operations create severe "blind spots" in global oil supply data (Red Sea). Vortexa appears to capture more dark activity via alternative methods, while Kpler and AXSMarine show steeper visible declines
(Red Sea).
The dual dynamic strongly suggests Riyadh is cautiously probing whether Persian Gulf loadings can resume through the still-contested Strait of Hormuz, even as it fights to keep Yanbu operational under dark protocols.
Bottom line: Saudi Arabia is caught between two contested maritime chokepoints. The Persian Gulf route faces periodic Iranian attacks in Hormuz; the Red Sea route via Yanbu faces a systematic Houthi blockade. The result is a strategic hedging operation — tentative Gulf loadings, fully dark Yanbu operations, surging Suez/Sumed diversions, and consideration of a pipeline capacity expansion — that has severely degraded global oil tracking visibility and left Saudi export volumes genuinely uncertain.
