Key Highlights

  • Brent crude briefly topped US$100 a barrel, its highest level since late May.
  • Houthi strikes on two Saudi tankers opened a second supply chokepoint in the Red Sea.
  • Crude is up about 35% this month and more than 60% year to date.

Brent crude briefly topped US$100 a barrel, its highest level since late May, after Houthi rebels struck two Saudi oil tankers in the Red Sea. The attack opened a second supply chokepoint alongside the already near-closed Strait of Hormuz. Crude has climbed roughly 35% this month and more than 60% year to date, feeding fresh inflation concerns across financial markets.

A second chokepoint emerges

The Red Sea strikes matter because they hit a corridor that was already carrying traffic diverted from other routes. With the Strait of Hormuz operating close to a standstill, the Red Sea had become an alternative artery for a share of seaborne crude and refined products.

Attacks on two Saudi vessels signal that this alternative is no longer secure, and shippers have limited options that avoid both flashpoints at once. Insurance premiums for tankers in the region have risen, and some operators may reroute cargoes around southern Africa, a longer and costlier journey that keeps freight rates elevated.

The price move in context

A 35% monthly gain and a rise of more than 60% year to date place crude among the sharpest commodity moves of the year. The speed of the advance, rather than the level alone, is what has unsettled equity and bond markets.

Energy is an input cost across nearly every sector, so a sustained move of this size feeds through to transport, manufacturing and household budgets. Central banks that had been weighing the timing of policy easing now face a supply-driven price shock that monetary policy cannot directly address.

Read-across to other markets

The oil move has coincided with weakness in equities, a firmer US dollar and higher government bond yields, a pattern consistent with markets repricing inflation risk. Airlines, shipping and energy-intensive manufacturers are typically most exposed to rising fuel costs, while integrated oil producers tend to see the opposite effect on revenue.

The duration of the supply disruption, rather than the headline price, will shape how lasting the impact proves.
