One of the largest U.S. refineries exploded and caught fire, with a daily processing capacity of 395,000 barrels—crude oil prices rebounded sharply!

A major accident struck a core U.S. refining facility, compounding escalating geopolitical tensions in Iran, driving a sharp one-day rebound in international oil prices. On March 23 local time, an explosion and large-scale fire broke out at Valero’s refinery in Port Arthur, Texas. According to Bloomberg’s citing of informed sources, the fire originated in the diesel hydrotreating unit, which suffered severe damage; the blaze then spread to the adjacent fluid catalytic cracking (FCC) unit area. Part of the refinery’s facilities has been shut down; whether full operations will halt remains pending final management decision. On the same day, several key Iranian energy nodes were again struck by airstrikes. Although U.S. President Donald Trump had just announced a five-day postponement of strikes against Iran’s energy infrastructure, local media reported that, early on March 24 local time, two energy facilities—in Isfahan and Khorramshahr—were attacked by U.S. and Israeli forces. Details reported indicate that in northern Isfahan, along Kaveh Street, a natural gas control building and a pressure-reduction station were struck, causing partial facility damage and affecting nearby residential buildings. Due to preventive safety measures taken by Iranian authorities—who had already taken the station offline prior to the attack—“a large-scale explosion was averted.” Fueled by news of the refinery explosion and further escalation in the Iran conflict, WTI crude oil prices surged from an intraday low of $85 per barrel to re-cross $90, reaching $91.63 as of latest reporting. According to CCTV News, the Valero refinery processes approximately 395,000 barrels of crude oil per day, ranking it among the top ten U.S. refineries and making it a critical node in America’s energy supply chain. U.S. retail gasoline prices have already surpassed $3.90 per gallon. Analysts warn that prolonged shutdown of this facility would place even greater strain on an energy market already under tightening pressure. Severe damage to the hydrotreating unit has forced partial refinery shutdown. According to CCTV News, the incident occurred on March 23 local time; the massive shockwave from the explosion rattled car windows across the entire Mid-County region.

Shale patch mergers and acquisitions may be booming—but refineries are falling behind.

After a two-year lull, U.S. merger and acquisition activity in the shale sector has surged forward significantly. Energy companies leveraged high stock valuations to execute $250 billion worth of aggressive acquisitions in 2023 alone. Just last quarter, U.S. oil majors ExxonMobil (NYSE: XOM), Chevron (NYSE: CVX), and Occidental Petroleum (NYSE: OXY) pursued failed deals totaling $125 billion to acquire low-cost oil fields—aiming to achieve cost-competitive balance amid volatile oil prices. Moreover, this year’s dealmaking momentum shows no sign of slowing: just weeks ago, Midland, Texas–based Diamondback Energy (NASDAQ: FANG) agreed to acquire Permian Basin producer Endeavor Energy in a $26 billion cash-and-stock transaction—a highly ambitious move for a company with a $32 billion market capitalization. Unfortunately, amid this M&A boom, one critical segment of the energy industry has conspicuously lagged: U.S. refining. Since the formation of independent refiners, virtually no refinery transactions have been completed—except for Pacific Refining’s $310 million acquisition of ExxonMobil’s Billings, Montana refinery last June. Industry insiders estimate the asset’s fair market value could be nearly double its sale price—roughly equivalent to $63,000 barrels per day of crude processing capacity. Despite numerous sellers willing to exit, the refining sector remains overlooked, primarily due to widespread concerns that the global energy transition away from fossil fuels could render many aging refineries stranded assets. An industry in despair The situation has grown dire for this struggling sector. Shell (NYSE: SHEL) was forced to permanently shutter its 240,000-barrel-per-day Norco refinery in Louisiana after failing to find a buyer. Delta Airlines’ century-old, 190,000-barrel-per-day Philadelphia refinery—on the market for six years—remains unsold to date. LyondellBasell’s Houston refinery is slated for closure in 2025, following two unsuccessful attempts to sell it. Even more seriously, these companies face soaring maintenance costs for their aging facilities—leading to increasingly frequent operational failures. Last year, major refiners Valero Energy (NYSE: VLO), Marathon Petroleum (NYSE: MPC), and Phillips 66 (NYSE: PSX) collectively incurred unplanned and planned downtime equivalent to 280,000 barrels per day—more than 20% higher than in 2019.
