Valero's Volatile Ride: Can Refiners Thrive Amidst Geopolitical Swings?

Is the current surge in refining stocks, exemplified by Valero Energy's impressive performance, a sustainable trend or a temporary boon driven by geopolitical uncertainty? The market's focus on the Strait of Hormuz, a critical chokepoint for global oil flows, certainly underscores the vulnerability of supply chains, yet the longer-term outlook suggests a more complex picture for companies operating in the energy sector.

Oil markets are undoubtedly facing significant structural changes, driven by intensifying geopolitical strains and economic uncertainties, as highlighted by the International Energy Agency. This volatility has been a key factor, with concerns about oil flows from the Middle East remaining constrained through the fourth quarter of 2026. For a company like Valero, which has seen its stock rise significantly—up 47.7% year to date and 76.6% over one year, with a multi-year return of 139.9%—this environment appears to be a tailwind, benefiting from a perceived scarcity and higher margins.

Refiners Ride the Geopolitical Wave, For Now

Refining companies, by their nature, often benefit from disruptions in crude oil supply, especially when they possess diverse sourcing capabilities. Valero's stock has shown remarkable resilience, trading at $244.13 as of June 17, 2026, with some analysts forecasting a robust future. Seeking Alpha recently named Valero a top pick for 2027, suggesting significant upside potential. Meanwhile, Goldman Sachs indicated in March 2026 that risks to oil prices remained skewed to the upside in the near term and into 2027, a sentiment that tends to support refining margins when crude supplies are tight.

Further supporting this near-term strength, the US Energy Information Administration (EIA) noted in February 2026 that near-term prices were propped up by winter-related disruptions and ongoing geopolitical risks. The agency also highlighted the stability of Iranian crude oil production, assuming it would remain stable despite potential conflicts that could reduce Middle East oil production.

The Looming Oversupply of 2027

Despite the immediate tailwinds, a significant shift in market dynamics is anticipated. The EIA's Short-Term Energy Outlook for February 2026 projected that global crude oil prices are expected to decline through 2026 and 2027. Specifically, Brent crude oil prices were forecast to average $58/bbl in 2026 and further decline to an average of $53/bbl in 2027. This downward trend, according to the EIA, reflects expectations for a looser global market balance and increased oil inventories.

More recent projections, such as those reported by Aegis Hedging in May 2026, reinforce this view, pointing toward large global oil surpluses in 2027. The EIA's updated outlook for 2027 now anticipates a surplus averaging roughly 3.7 MMBbl/d, significantly higher than previous estimates. This substantial surplus is attributed to several key factors.

First, US crude production is expected to be stronger than previously thought, potentially exceeding an average of 14 MMBbl/d in 2027 for the first time on record. Second, weaker global demand expectations contribute to the surplus. Third, accelerated non-OPEC supply growth is a major driver, with the UAE, now operating outside OPEC production quotas, projected to increase its output to more than 5.1 MMBbl/d in 2027. Additionally, other non-OPEC+ producers, excluding the US and UAE, are expected to add over 1.2 MMBbl/d of additional supply in the same year.

Navigating Future Market Imbalances

For refiners, a market shifting from immediate geopolitical supply risks to medium-term looser balances presents a complex challenge. While lower crude input costs might initially seem beneficial, an oversupplied market often signals softening demand for refined products, which can erode profit margins. The EIA also notes that global liquid fuels consumption growth is driven almost entirely by non-OECD countries, with OECD consumption expected to grow only slightly through 2027.

Policy actions, such as the US Department of the Treasury's expanded scope of general licenses for transporting and selling Venezuelan crude oil, could further contribute to increased supply and downward pressure on prices. The EIA estimates these additional shipments could help Venezuelan oil production recover to pre-lockdown levels by the second quarter of 2026.

While some analysts remain bullish on individual refining stocks like Valero, the broader macro environment, as forecast by the EIA and other agencies, suggests a potential inflection point for the energy market. The current advantages enjoyed by refiners due to supply constraints may well diminish as global production catches up and eventually outpaces demand by 2027. Investors in the energy sector will need to carefully weigh the short-term benefits of geopolitical volatility against the longer-term projections of an increasingly oversupplied crude market.
