Brent crude reached its highest level in five months on Tuesday as reports of attacks on commercial vessels and claims of strikes against Saudi Arabian infrastructure increased concerns about Middle Eastern oil supplies.
The international oil benchmark climbed to $111.05 a barrel, its highest level since May, before trading at $110.80 at 08:10 GMT, up $1.25, or 1.1%.
US West Texas Intermediate (WTI) crude rose to $104.94 a barrel, its highest level since September, before easing slightly to $104.80, an increase of $1.14, or 1.1%.
The price movements reflected a higher geopolitical risk premium as traders assessed the potential consequences of renewed regional instability for oil production and maritime transportation.
Houthi Attack Claims Increase Concerns Over Saudi Energy Infrastructure
Yemen’s Iran-aligned Houthi movement said on Monday that it had launched several attacks against energy, airport and military facilities in Saudi Arabia.
The group identified an Aramco facility in Yanbu, the Shaybah oilfield, Riyadh’s King Khalid International Airport and Abha airport among its targets.
Saudi authorities did not immediately confirm the claims, and Reuters said it could not independently verify the reported attacks.
The allegations nevertheless contributed to concerns about the security of regional energy infrastructure and the potential for further disruption.
Separately, an attack attributed to the Houthis on a training camp for government security forces in Yemen’s Shabwa province reportedly killed 58 people and injured more than 200 on Monday.
The developments added to uncertainty about regional stability at a time when oil markets remain sensitive to threats against production facilities and shipping routes.
Reported Vessel Attacks Keep Shipping Risks in Focus
Maritime security concerns have also contributed to the increase in oil prices.
Shipping intelligence company Kpler said in a Monday note that at least 18 vessels had reportedly been attacked over the preceding two weeks.
The incidents have maintained concerns about the safety of commercial shipping and the reliability of energy transportation routes in the region.
For oil markets, the principal uncertainty is whether further attacks could interfere with the movement of crude and refined products.
Even without confirmed production losses, the possibility of shipping disruption may influence prices by increasing the compensation traders demand for geopolitical risk.
However, the financial impact depends on whether reported threats translate into sustained interruptions to physical oil flows.
ING Analysts Highlight Risk Premium in Oil Prices
ING analysts said the latest price movements indicated that traders were assigning additional value to the risk of supply disruption.
In a note published Tuesday, the analysts stated:
“Oil prices remain well-supported … This suggests the market is pricing in a significant risk premium, given the situation’s volatility.”
They also identified the continuation of physical oil shipments as an important factor in determining whether that premium persists.
“However, if flows continue uninhibited despite the geopolitical environment, the risk premium would likely erode slowly. Clearly, there are no signs of this yet.”
The assessment suggests that oil prices are being influenced not only by current supply conditions but also by uncertainty about future transportation and infrastructure security.
If physical shipments continue without major interruptions, some of the geopolitical premium could diminish. Continued attacks or further disruption, however, may sustain uncertainty.
US Crude Inventories Add Another Market Consideration
Alongside geopolitical developments, traders are awaiting further information about US petroleum inventories.
A preliminary Reuters survey published Monday indicated that analysts expected US crude oil stockpiles to have declined during the previous week.
Inventories of refined petroleum products were also expected to have fallen.
Changes in US inventories provide an additional indication of supply and demand conditions, although the figures cited were analyst expectations rather than confirmed inventory data.
The anticipated reductions may provide another factor for traders to consider alongside developments in the Middle East.
What Investors Will Watch Next
The immediate focus for energy markets remains the security of Saudi Arabian infrastructure and commercial shipping routes.
Confirmation or clarification of the reported attacks, together with evidence of any disruption to physical oil deliveries, could influence the geopolitical risk premium embedded in crude prices.
Investors will also monitor US inventory figures to assess whether domestic supply conditions reinforce or offset the impact of Middle Eastern developments.
For energy producers, refiners, transportation companies and other oil-dependent businesses, the persistence of prices above $100 a barrel may have different financial implications depending on their exposure to crude prices and operating costs.
