Global oil markets are entering the final week of May 2026 with crude prices poised for a slight increase, a movement that underscores persistent geopolitical uncertainty and a tightening physical supply. West Texas Intermediate (WTI) crude oil closed Friday, May 22, up 0.67% to settle at $97 per barrel, contributing to a 1.20% gain over the past month. Brent crude, the international benchmark, continued to hover near $105 per barrel, with WTI close behind at $98 per barrel, reflecting deep-seated anxieties across the energy sector.
This upward momentum, even if modest on a daily basis, signals a market under considerable stress, grappling with an acute supply deficit and ongoing disruptions to critical shipping routes. For consumers and industries globally, particularly in energy-importing nations across Southeast Asia, these sustained high prices translate into elevated costs for fuel, transport, and manufacturing, impacting inflation and economic stability at a precarious time. The slight price uptick is not an isolated fluctuation but a symptom of a fragile balance between supply and demand, with significant consequences for public interest.
The primary driver behind these elevated prices and the current upward pressure stems from the escalating conflict between the United States and Iran. This geopolitical tension continues to cast a long shadow over global energy security, directly impacting the availability and flow of crude. Its most tangible effect is seen in the Strait of Hormuz, the narrow waterway through which an estimated 20% of the world's oil shipments normally pass.
Market concerns remain centered on the Strait of Hormuz, where an effective closure or even severe disruption has already significantly curtailed global supply chains. Current estimates indicate that oil exports through this vital chokepoint have dwindled to approximately 5% of normal levels, siphoning millions of barrels per day from the global market. This dramatic reduction has created an unprecedented tightening in the physical oil market, leaving little room for error or further shocks.
Analysts at Barclays, for example, maintain their $100 Brent forecast for 2026, but issue a stark warning that price risks are decidedly skewed to the upside. They point to global oil inventories drawing at a record pace, a direct consequence of the Strait's diminished capacity. The rapid depletion of both private and government strategic oil reserves means the market is operating with virtually no buffer against additional supply disruptions.
The U.S. Energy Information Administration (EIA) projects that global oil inventories will draw by an average of 8.5 million barrels per day in the second quarter of 2026. This projected drawdown is expected to keep Brent prices hovering around $106 per barrel throughout May and June, intensifying fears of price spikes should geopolitical tensions further escalate or if the restoration of Middle Eastern production faces continued delays.
In response to the tight market, OPEC+ nations have announced a modest increase of 188,000 barrels per day (bpd) to their production quotas. This adjustment, set to be solidified at their June 7 meeting, marks the third consecutive monthly rise in quotas. However, market experts caution that these theoretical increments are doing little to alleviate the tightness in the physical market as long as critical shipping routes, particularly the Strait of Hormuz, remain precarious. The ongoing tensions are causing significant bottlenecks that effectively diminish the impact of any production increases on global availability.
Despite intermittent diplomatic talks between Washington and Tehran, investors remain largely skeptical of a swift or lasting resolution. Market sentiment has exhibited violent swings, reacting sharply to headlines suggesting progress, only to reverse course when negotiations stall. Officials from both sides reportedly remain divided on key issues, including uranium oversight and control over the Strait of Hormuz. Though recent comments from U.S. officials about "good signs" in the talks have offered glimmers of hope, the underlying uncertainty persists.
A recent Bloomberg Intelligence survey of 126 asset managers and energy specialists revealed that most participants anticipate crude prices will be capped near $100 a barrel over the next year. Crucially, almost two-thirds of respondents believe a lasting risk premium of $5 to $15 per barrel will remain embedded in oil prices for years to come. The survey highlighted "demand destruction" as the most probable mechanism to offset persistent supply deficits, suggesting that higher prices themselves will be the primary tool for balancing the market.
Further analysis of U.S. crude inventory data indicates that recent draws, often interpreted as bullish signals, are in fact driven by exports rather than robust domestic demand. This trend further illustrates the global nature of the supply crunch, as U.S. crude is diverted to help address international shortages. Data on refined products, such as gasoline inventory misses and distillate builds, corroborate the picture of weak domestic consumption.
These consumption trends align with downwardly revised global demand forecasts from both the International Energy Agency (IEA) and OPEC. The IEA’s May report projected a contraction in global oil demand by 420,000 bpd year-on-year in 2026, a significant revision from earlier forecasts. This indicates that while demand is indeed softening, the market tightening is predominantly a result of a severe supply collapse outpacing any decline in consumption.
The current global oil market is navigating a treacherous landscape where geopolitical risks dominate, and the physical availability of crude is severely constrained. While the notion of "slightly up" oil prices for the last week of May might sound modest, it signifies a market struggling to meet demand in the face of unprecedented supply disruptions, keeping consumers and industries globally on edge for the foreseeable future.
Looking further ahead, forecasters anticipate a potential easing of prices, but not anytime soon. Both the EIA and the IEA project that prices could fall to an average of $89 per barrel in the fourth quarter of 2026 and further to $79 per barrel in 2027. However, this hinges entirely on the assumption that Middle East production successfully comes back online and supply normalizes, a scenario heavily dependent on the resolution of regional conflicts.
Morningstar DBRS, while raising its full-year 2026 Brent and WTI forecasts to $80/bbl and $75/bbl respectively to account for the current acute global supply shortage, still posits that prices will remain elevated for at least a few months even after the conflict ends and the Strait of Hormuz reopens. This assessment is based on the necessity to restore confidence and re-establish Gulf energy production, which cannot happen instantly even with a political resolution.
The path forward for oil prices remains intricately linked to the resolution of regional conflicts and the restoration of normal trade flows through vital chokepoints, particularly the Strait of Hormuz. Until significant progress is made on these fronts, the market will likely continue to reflect deep-seated uncertainties, with consumers bearing the brunt of sustained high energy costs.
