RIYADH, July 20 — The Houthi blockade declaration in the Red Sea has sent a jolt through global oil markets, raising fresh questions about the security of a waterway that carries millions of barrels of Saudi crude every day. Brent crude futures climbed three percent on the first trading day after the announcement, closing at $87.50 per barrel.
For Asian economies that import the bulk of their energy from the region, the chokepoint is more than a strategic concern — it touches the fuel supply that powers industry, transport, and households across the continent. Saudi Arabia, the world’s second-largest holder of proven oil reserves with 267 billion barrels, produced roughly 10.5 million barrels per day in 2022.
Of that, about 7 million barrels were exported daily. A significant share — approximately 4 million barrels per day — travels through the Bab el-Mandeb strait on its way to customers in Europe, Asia, and the United States. The remainder moves via the Strait of Hormuz or through pipelines to Red Sea terminals.
Globally, some 6.2 million barrels of oil transit the Bab el-Mandeb each day, according to a 2023 estimate from the U.S. Energy Information Administration.
A familiar risk, higher stakes
This is not the first time a disruption in Saudi supply has rattled markets. In 2019, an attack on Saudi facilities cut production by 5.7 million barrels per day, causing a 15 percent surge in oil prices. The current blockade, while different in nature, carries its own set of immediate costs.
Insurance premiums for vessels operating in the Red Sea area have risen 50 percent since the blockade announcement, according to estimates from Lloyd’s of London. For shippers, the alternative route around the Cape of Good Hope is significantly more expensive: transit tolls for a Suezmax tanker are about $30,000 per day through the Bab el-Mandeb, compared to $45,000 for the longer route.
The higher insurance and shipping costs will eventually ripple into the prices paid by refiners and, ultimately, by families across Asia who rely on imported petroleum products. The region is home to some of the world’s fastest-growing economies, many of which depend heavily on Middle Eastern crude. Brent crude averaged $99 per barrel in 2022, with spikes reaching $130 after the Russian invasion of Ukraine.
Any sustained increase would compound pressures from already-elevated global energy prices.
Saudi strategy amid uncertainty
Saudi Arabia has invested heavily in energy security through its Vision 2030 plan, a $500 billion effort to expand production and refining capacity. The kingdom holds the world’s second-largest proven oil reserves, giving it a long-term buffer. But the Bab el-Mandeb blockade highlights a vulnerability that no amount of domestic investment can fully address: the dependence on narrow, contested sea lanes to reach global markets.
For now, the immediate focus is on how long the disruption lasts and whether alternative routes or increased production from other suppliers can offset the shortfall. Asian governments and refiners are closely watching the insurance and freight markets, knowing that any sustained disruption will show up in the cost of fuel.
The blockade has not yet caused a physical shortage, but the price signal — a three-percent jump in futures — is a reminder of how quickly a distant chokepoint can become a pocketbook issue for communities across Asia.
