Summary¶
Three Chinese supertankers (VLCCs) carrying approximately 6 million barrels of crude oil exited the Strait of Hormuz in May 2026 via an Iranian-cleared transit corridor — evidence that diplomatic channels between Beijing and Tehran are operating to preserve China's oil supply despite the broader Hormuz commercial shipping standstill.
Data from Lloyds List Intelligence and Reuters tracking showed the vessels navigated through waters cleared by Iranian authorities, representing a politically filtered exception to the general commercial shipping halt through the Strait.
Key Data Points¶
| Data Point | Value |
|---|---|
| Vessels | 3 Chinese VLCCs (Very Large Crude Carriers) |
| Total cargo | Approximately 6 million barrels of crude oil |
| Transit corridor | Iranian-cleared passage (political filtering, not general commercial access) |
| Transit date | ~May 20, 2026 |
| Normal Hormuz daily transits | ~95 vessels/day (IMF PortWatch pre-crisis baseline) |
| Current commercial transit (May 17) | ~2 vessels/day (2% of normal) — per IMF PortWatch via Straits.Live |
| War-risk insurance VLCC | ~$2.5 million/voyage; 8.0× pre-crisis |
Broader Hormuz Status (May 25, 2026)¶
Per Straits.Live real-time monitoring:
- Crisis Pressure Score: 94/100 (Extreme) — sustained crisis levels
- Escalation Probability (30-day): 37/100 (Watchful)
- Brent Spot: $116.73/barrel (+2.43% in 24h; +62.1% vs pre-crisis ~$72)
- IMF PortWatch (May 17 most recent published day): 2 vessels transited vs ~95/day typical
- War-risk insurance: 8.0× pre-crisis; 6 P&I clubs have withdrawn cover entirely
- Container carriers rerouting: All 9 major carriers (MSC, Maersk, CMA CGM, COSCO, Hapag-Lloyd, ONE, Evergreen, HMM, Yang Ming) are routing Asia-Europe via Cape of Good Hope
- 32 vessels granted passage May 25 per Iranian media — early signal of partial reopening under ceasefire framework
Political Dimension¶
The Chinese tanker transits represent a politically filtered exception — China, as a major importer of Iranian oil and a country with strategic interests in Middle East stability, is utilizing diplomatic channels to secure energy supply even as general commercial shipping remains choked.
This contrasts with the experience of Western and European carriers who face:
- 8× war-risk insurance premium
- P&I club withdrawal of coverage
- Mandatory Cape of Good Hope rerouting
