**Summary**: Two major Chinese shipping firms have reportedly suspended oil tanker voyages through both the Strait of Hormuz and Bab el‑Mandeb. This raises immediate concerns over crude and product flow security on key chokepoints and could widen freight spreads and risk premia on Middle East–Asia routes, supporting Brent and Dubai benchmarks.

## Detail

1) What happened:
Reuters reports that two large Chinese shipping companies have halted oil tanker transits through both the Strait of Hormuz and Bab el‑Mandeb. This comes against a backdrop of recent IRGC attacks on vessels in Hormuz and a broader escalation risk as a U.S.–Iran ceasefire framework frays. While the report does not specify duration or the exact fleets affected, these firms are among the larger carriers moving Middle Eastern crude to Asia.

2) Supply/demand impact:
The physical barrels are not yet confirmed to be shut in at the wellhead, but logistical capacity and routing options are being constrained. A temporary halt by two major tanker operators could effectively sideline several hundred thousand barrels per day of normal transport capacity on these lanes until alternative carriers or insurance arrangements are in place. At minimum, this will reroute cargoes, extend voyage times, and push up freight rates and war risk premiums. If more Chinese or global carriers follow, practical exportability of Gulf crude (especially to Asia) could be impaired by 0.5–1.5 mb/d on a rolling basis, even if production technically continues. Demand is not fundamentally destroyed here; instead, delivery risk and timing uncertainty increase, which historically lifts prompt spreads and flat prices.

3) Affected assets and direction:
Brent, Dubai, and Oman benchmarks should see upward pressure, particularly on front-month contracts and prompt time spreads (backwardation steepening). Asian refining margins may compress if delivered costs rise faster than product cracks, and Middle East–Asia VLCC freight (TD3C) and Red Sea–Asia routes are likely to spike. European and U.S. benchmarks (WTI, ICE Gasoil) could gain on substitution and general risk sentiment. Insurance premia for transiting both chokepoints will likely rise, which is bullish for tanker owners’ earnings but negative for importers’ costs.

4) Historical precedent:
Episodes such as the 2019 attacks on tankers near Hormuz and the 2021–2023 Houthi attacks around Bab el‑Mandeb/Suez showed that even limited disruptions or self-imposed routing changes by large shippers can move Brent and freight markets by several percent over days to weeks.

5) Duration:
Impact will depend on whether this is a short-term precaution or a sustained policy. As of now, expect at least a days-to-weeks effect on risk premia and freight; if replicated by additional carriers or paired with further attacks, the market impact could become more structural.
