International benchmark oil prices have decisively broken through the $100 per barrel threshold, with both West Texas Intermediate and Brent crude hitting multi-month highs. Market analysts suggest there could be further upside potential, with some projecting crude could reach $120 per barrel if geopolitical tensions continue to escalate. With supply conditions tightening, Asian buyers are once again paying premium prices to secure cargoes from regions including the United States and South America.

The current market dynamic shows oil prices climbing in tandem with US Treasury yields, creating significant headwinds for equity markets, particularly growth-oriented technology stocks.

Saudi Pipeline Disruption Fuels Price Rally

The shutdown of Saudi Arabia's critical oil transit pipeline last week emerged as one of the primary catalysts behind the recent price surge. The kingdom relies on an approximately 1,200-kilometer east-west pipeline crossing the desert nation to transport crude from processing facilities near the Persian Gulf to the Red Sea. From there, oil is typically loaded onto tankers destined for European markets via the Suez Canal or routed toward Asia through the Bab el-Mandeb Strait. A drone attack on September 11 forced the temporary closure of this vital infrastructure.

As the world's largest oil exporter, Saudi Arabia depends on this pipeline to move roughly four million barrels per day, representing about 4% of global supply, to the Yanbu port on the Red Sea. According to Johannes Raubal, senior crude analyst at vessel data firm Kpler, Yanbu's current inventory stands at approximately 15 million barrels, which at normal export rates would be exhausted within roughly four days.

The Strait of Hormuz and the Bab el-Mandeb, two of the world's most critical maritime chokepoints for oil transportation, are both facing reduced capacity due to ongoing armed conflicts. Before recent hostilities, approximately 20 million barrels of oil daily transited the Strait of Hormuz. In the first week of September, Lloyd's List Intelligence data showed 90 tankers passed through the strait, compared with roughly 130 per day prior to the conflict.

Yemen's Houthi forces have meanwhile intensified their control over the Bab el-Mandeb Strait. Analysts at Melineus Research estimated on Monday that while approximately three million barrels of oil moved through the strait in early September, that figure now stands at effectively zero.

Dong Xiucheng, executive director of the China International Carbon Neutral Economy Research Institute at the University of International Business and Economics, told reporters that the price rally isn't attributable solely to the pipeline incident. Earlier disruptions to Middle East shipping lanes, sustained production cuts by OPEC+, and historically low global crude inventories had already placed the market in a delicate balance. The Saudi pipeline outage served as a trigger for the price jump rather than the root cause. If the pipeline is repaired swiftly, the supply shock can be absorbed gradually; however, prolonged downtime that depletes inventories would widen the global supply deficit and intensify upward price pressure.

Asian Buyers Pay Premium Prices for US and South American Crude

The rally has already transmitted to the physical market, with spot premiums for Dubai and Oman benchmark crudes reaching their highest levels since March, reflecting intense competition among buyers for cargoes. Premiums for West African, US, and Latin American grades have also hit multi-month highs.

An anonymous trading executive at an Asian refinery noted a key difference from the March run: "Back then, there was simply no oil available to purchase. Now supply exists, but we must pay considerably higher prices."

Trade sources reveal that South Korea's SK Energy purchased four million barrels of US WTI crude last week for December delivery, at a premium of approximately $24 per barrel over the November Brent swap contract. GS Caltex secured two million barrels of US crude at a similar premium on a delivered basis against the November Dubai benchmark, compared with a premium of only about $13 per barrel for US cargoes transacted the previous month.

Andreas H. Lien, vice president of crude trading at Norway's Equinor, commented on the sidelines of last week's Asia Pacific Petroleum Conference: "The fundamental picture for crude is constructive, and supply is tightening. It's clear that Asian buyers are once again paying higher prices to source crude from the US and South America."

The refined products market is feeling similar effects. US auto club AAA data shows the average diesel price in the United States surpassed $6 per gallon for the first time last week. Andy Lipow, president of Lipow Oil Associates, predicted in a research note that if Saudi Arabia's east-west pipeline remains offline for an extended period, US diesel prices could climb above $6.50 per gallon.

Institutions Project Oil Prices Could Reach $120

Several institutions believe international oil prices have yet to peak. S&P Global Energy's base-case scenario projects average crude prices of just under $100 per barrel through 2027. Should sustained disruptions to Strait of Hormuz traffic continue, prices could rise toward $120 per barrel, though they would fall below $60 in a rapid recovery scenario.

Wood Mackenzie, a global energy research firm, forecasts spot Brent prices climbing to near $110 per barrel around late 2026 and early 2027 before retreating to approximately $60 per barrel by early 2028, assuming full normalization of Hormuz traffic flows by January 2027.

Dong Xiucheng observed that some overseas institutions project oil prices surging as high as $120 to $150 per barrel, but characterized such forecasts as extreme risk scenarios rather than baseline expectations. For prices to genuinely approach or exceed $120, the Middle East conflict would need to escalate continuously, causing sustained damage to critical oil infrastructure and shipping lanes that results in large-scale, prolonged supply disruptions. The $150 figure would represent a tail-risk outcome contingent on full-blown conflict expansion.

Dong maintains that without further deterioration in the geopolitical situation, pipeline repairs and strategic inventory releases could offset part of the supply gap, making it unlikely prices will hold at elevated levels sustainably. Additionally, high oil prices typically dampen global demand, and nations may release strategic petroleum reserves, creating natural constraints. The $120 to $150 range therefore represents an upper risk boundary rather than a probable baseline scenario.

Looking ahead, Dong predicts crude prices are unlikely to sustain a one-directional surge over the medium to long term. The trajectory will depend on the evolution of geopolitical conflicts, OPEC+ policy adjustments, and global macroeconomic performance, with prices likely to fluctuate broadly within a range while geopolitical risk premiums persist.

High Oil Prices Weigh on Treasury and Equity Markets

Elevated crude prices are exerting mounting pressure on both US Treasury and equity markets. Oil and Treasury yields are currently moving in remarkably high synchronization, according to CNBC reports, as investors grow increasingly concerned about inflation. The concurrent movement of these two asset classes is amplifying overall market stress.

BMO Capital Markets data shows the one-month rolling correlation between front-month WTI crude and the 10-year Treasury yield has climbed to 0.96, the highest positive correlation since June 2019, with such elevated linkage last seen in October 2014.

Ed Yardeni, president of Yardeni Research, describes a clearly defined transmission chain: energy prices to inflation, inflation to bonds, bonds to monetary policy, and ultimately monetary policy to equities. "If oil keeps climbing, Treasury yields follow higher, which is unequivocally negative. Rising inflation expectations would increase the likelihood that the Federal Reserve resumes its rate hiking cycle, potentially through two or three additional increases, which would inevitably roil equity markets."

Kishore "Kal" Sri-Kumar, president of Sri-Kumar Global Strategies, is already advising clients to avoid the most rate-sensitive assets. He favors short-duration fixed income and defensive equities while recommending physical assets including real estate, copper, and gold as hedging vehicles. Technology growth stocks appear particularly vulnerable in a persistently elevated rate environment.

"A bond bear market is underway with yields continuing to climb, and I see nothing that could stop crude and natural gas prices from heading higher," Sri-Kumar concluded.
