Bahrain Refinery Attack and the Widening Brent-WTI Oil Price Gap

Escalating regional conflict in the Middle East has disrupted operations at Bahrain’s national energy company, Bapco Energies, prompting a force majeure declaration. This disruption, coupled with ongoing geopolitical tensions, is contributing to a significant widening of the price gap between Brent and West Texas Intermediate (WTI) crude oil, reaching levels not seen in over a decade.

Bapco Refinery Attack and Force Majeure

On March 9, 2026, Bapco Energies declared force majeure following an attack on its refinery complex Gulf News. The attack, occurring amidst broader regional conflict, has impacted several of the company’s operations. Despite the disruption, Bapco Energies has assured that domestic energy supplies remain secure through pre-existing contingency plans and emergency response measures Gulf News. The company clarified that the force majeure relates specifically to operational disruptions linked to the conflict and the attack on the refinery Bapco Energies.

Reports indicate the refinery was directly hit by an Iranian ballistic missile MSN, and some sources suggest the refinery is critically significant to Bahrain’s economy, generating 70-85% of the state’s revenue LinkedIn. Oil is supplied to the refinery from both Bahrain’s fields and via pipeline from Saudi Arabia LinkedIn.

Brent-WTI Price Divergence

The attacks on energy infrastructure in the Middle East have imposed a “war premium” on Brent crude oil, the benchmark for crude oil from the region. As of March 20, 2026, the spread between Brent and WTI crude oil has widened to $12.05 per barrel, the largest price difference in 11 years, since March 2015.

WTI, distributed through the North American pipeline network, is less exposed to the immediate geopolitical risks affecting the Middle East. The United States maintains a high self-sufficiency rate in oil production, with commercial crude oil inventories at 449.3 million barrels as of March 18, 2026, an increase of 6.2 million barrels from the previous week.

U.S. Arbitrage and Global Impact

Some analysts suggest the United States is benefiting from this price disparity, protecting its domestic market with relatively inexpensive WTI while exporting surplus crude oil at the higher Brent price, effectively moving capital back into the country.

This price difference has spurred arbitrage trading, with increased shipments of WTI to Europe. Freight rates for Aframax-class ships transporting crude oil from the U.S. Gulf of Mexico to Europe have risen from $4.36 million to $6 million, but the WTI-Brent spread provides sufficient margin to offset these costs.

Yet, the situation is creating hardship for Asian and European refining and logistics industries, which are heavily reliant on energy imports. Gasoline prices in Japan rose 18% in one week, and factory operation rates at Japanese oil refineries fell from 80% to 69.1% in mid-March. India experienced a 26.3% decline in liquefied petroleum gas (LPG) sales due to soaring energy bills.

Broader Economic Implications

The surge in oil prices is also impacting air cargo, with increased demand for air freight as routes through the Strait of Hormuz and Red Sea become constrained. E-commerce platforms are utilizing numerous cargo planes, driving up global air freight rates.

While the U.S. May see trade benefits, rising energy costs are also impacting American consumers, with gasoline and diesel prices increasing by over 20% following the outbreak of the conflict. A strong dollar combined with high oil prices could lead to a decline in global trade volume, potentially decreasing demand for U.S. Exports.

European and Asian countries are accelerating their energy transition efforts to reduce dependence on Middle Eastern fossil fuels. The Federal Reserve is expected to maintain a hawkish monetary policy in response to rising inflation, with expectations for interest rate cuts by the end of the year diminished.

Importing countries in Asia are facing a compounded economic burden due to rising oil prices and depreciating currencies. The Indian rupee hit a record low, and concerns about foreign exchange losses led to significant outflows from the Indian stock market. Japan’s yen is also under pressure, and the country faces the risk of stagflation.
