Part of Attacks in the Red Sea are causing global transit disruptions, leading to increased shipping costs for Far East to Europe trade, while Saudi Arabia diverts crude exports through Yanbu port.

How could the Houthi naval blockade on Saudi Arabia affect Brent crude oil prices?

Likely What happens if… A possibility worth considering, not a forecast.

The blockade could cause global oil supply to drop by 7 percent, spiking Brent crude prices. The Houthi naval blockade targets Saudi Arabia's exports through the Bab el-Mandab Strait, a vital gateway to the Red Sea. The full closure of this strait would reduce global oil supply by an estimated 7 percent, as most Saudi oil exports would be unable to leave the region. Furthermore, the disruption forces ships to detour around the Cape of Good Hope, adding around two weeks to shipping routes, which increases operational costs. This combination of reduced supply and heightened market risk directly causes volatility and price surges in the Brent crude oil market.

  • The war in the Gulf has already reduced global oil shipments by 10 percent of global supply.nikkei.com

Why it matters

Brent crude is a global benchmark for oil prices, and its volatility directly impacts the cost of energy worldwide. Since Saudi Arabia is a major exporter and the Bab el-Mandab Strait is a vital lifeline for its economy, any disruption here immediately raises concerns about global energy security and supply stability.

This crisis adds to existing geopolitical pressures, as the Strait of Hormuz is also subject to disruption. The combination of blockades and conflict in the Arabian Peninsula creates a scenario where a significant portion of the world's oil supply could be threatened, potentially eclipsing earlier crises.

What we don't know yet

  • Will diplomatic efforts between regional powers succeed in stabilizing the Bab el-Mandab Strait?
  • How will the increased shipping costs be absorbed by global logistics companies?

What would change this answer

The Houthis successfully enforce a full closure of the Bab el-Mandab StraitThe reduction in global oil supply would increase beyond the estimated 7 percent, leading to a more severe and prolonged spike in Brent prices.
Mediators successfully broker a ceasefire and de-escalation in the Red SeaShipping routes would normalize, allowing tankers to resume transit through the strait, which would rapidly reduce market risk and stabilize oil prices.
