Oil spikes as shipping routes face attacks

What's happened

Oil prices have surged above $100 a barrel this week after the U.S.-Iran exchanges and Houthi operations disrupted tankers and energy facilities. Saudi authorities have reported repeated attacks on a Gulf-to-Red Sea pipeline and Houthi gains imperil Red Sea routes, forcing rerouting and pushing bond yields and fuel costs higher.

What's behind the headline?

What is driving prices

• Direct attacks on shipping and oil infrastructure have cut flows through the Strait of Hormuz and pushed some Saudi exports onto longer Red Sea/Suez routes. That is raising transport costs and stretching available tanker capacity.
• The Houthi campaign in the Red Sea and recent reported seizures of territory have increased the risk premium on shipments transiting Bab al‑Mandeb. Insurers and shipping firms are re‑routing or charging higher premiums, which will raise delivered fuel costs.

Who is bearing the cost

• Refineries and trading houses are absorbing higher freight and insurance bills now and will pass them onto consumers in coming weeks through higher gasoline, diesel and jet fuel prices.
• Governments will face higher inflation and borrowing costs; yields have already risen as markets price persistent energy disruption into interest‑rate expectations.

Why demand weakness is not offsetting supply risk

• China has cut crude imports this year and has drawn down inventories, which has cushioned the market so far. But visible stockpiles and demand flexibility in a single large importer cannot fully neutralise sustained shipping disruption.

Likely path ahead

• Oil prices will remain elevated while the Strait of Hormuz and Red Sea routes are risky. Traders will push forward contract prices to reflect insurance and rerouting costs, which will force refined fuel prices higher over the next month.
• Central banks will face stronger inflation data as energy feeds through to consumer prices; that will increase the chance of near‑term rate hikes and keep government bond yields elevated.

Bottom line

• The market has less slack than it appeared to have. Continued strikes, pipeline disruptions or further Houthi gains will force more exports onto expensive routes and will sustain higher oil and refined‑fuel prices into late 2026.

How we got here

The crisis began after U.S. strikes on Iranian vessels and Iran's reprisals, which have expanded into attacks on commercial shipping and Saudi energy sites. The Strait of Hormuz and the Bab al‑Mandeb/Red Sea have become contested chokepoints, forcing longer, costlier export routes and drawing down global spare capacity.

Our analysis

The New York Times has tracked the escalation across the Gulf and Red Sea, reporting that "a critical pipeline that carries oil from the Persian Gulf to the Red Sea had been 'targeted multiple times'" and that Saudi exports have fallen to their lowest levels in years (New York Times Business, Sept. 11 and Sept. 10). The Times also cited Kpler data showing Saudi exports slipping and noted the IEA has "lowered its forecast for global oil demand this year," signalling both supply disruption and demand weakness. The BBC emphasised the macroeconomic knock‑on: "the price of oil has jumped to $105 a barrel... fuelling fears that inflation could accelerate," and tied high gas prices to higher bond yields in the UK (BBC Business, Sept. 10). Business Insider and Goldman Sachs commentary provide the demand‑side context: Business Insider quoted analysts saying China has cut imports by roughly 40% between February and May and that China’s large stockpiles and refining flexibility have helped cushion markets (Business Insider UK, Sept. 10). Market pieces in CNBC and the New York Post documented immediate market reactions—stocks and bond yields moving as traders price in higher energy costs and potential Fed action (CNBC, Sept. 8; New York Post, Sept. 8). Taken together, the reporting shows a market being squeezed from both supply disruptions—pipeline attacks, Houthi operations and rerouting—and persistent inflationary consequences in major economies.
