The channels
- Direct supply disruption. Specific incidents — tanker attacks, pipeline strikes, refinery damage — that physically remove barrels from the market.
- Chokepoint risk. Even without disruption, plausible threats to Hormuz or Bab el-Mandeb add a risk premium to the global benchmark.
- Sanctions effects. Tightened enforcement of Iranian-export sanctions removes Iranian barrels from the price-discovery market.
- Strategic reserve announcements. Coordinated releases from the US SPR and IEA partners offset disruption pricing.
- Demand-side substitution. Buyers (especially Asian refiners) hedge by switching to non-Gulf grades, supporting differentials.
Why the headline-price move is the wrong number
"Brent spiked 5% on the news" is the cheapest possible reporting. The informative numbers are: which contract month moved most (front month vs deferred), how the spreads shifted (backwardation deepening signals expected near-term tightness), how the war-risk premium component changed in tanker rates, and how regional differentials moved (Dubai vs Brent vs WTI).
What does not move oil prices
- Political statements without operational implications.
- Casualty figures that do not affect production or transit.
- Diplomatic readouts that do not change physical or sanctions facts.
