Oil Prices Slide Over 2% Amid SPR Return Plans, OPEC Supply Drop

Front-month WTI crude oil futures fell sharply on Friday, trading down 2.99% to $90.26 per barrel. The global Brent benchmark also dropped, losing 2.19% to $92.95. The price for Bakken crude at the Clearbrook, Minnesota hub was at a discount of $3.42 per barrel to WTI.

The day's decline comes despite continued supply tightness from the Middle East conflict. According to a Rigzone survey summary published Friday, the war between a U.S.-Israeli alliance and Iran has taken a heavy toll on oil supplies from the Middle East, causing OPEC output to plunge further.

Market attention shifted Friday to news regarding the replenishment of the U.S. Strategic Petroleum Reserve (SPR). Energy Secretary Chris Wright said Friday that companies that borrowed crude from the SPR during the conflict will return those barrels with premiums attached, according to a report from OilPrice.com. This would leave the reserve about 40 million barrels larger than it would have been otherwise once the war ends.

The Department of Energy has loaned roughly 133 million barrels from the reserve since the crisis erupted, with borrowers required to return the crude plus premiums of up to 24%. "We're flowing oil to the marketplace in the short term when it needs it, and we're trading those barrels," Wright said on Fox Business. The SPR inventory stood at 357.1 million barrels for the week ending May 29, down from roughly 415 million barrels in early March.

The prospect of a significant volume of crude eventually returning to federal storage, rather than being sold into the market, may be applying some downward pressure on prices. However, underlying physical market tightness persists. OilPrice.com reported that commercial crude inventories, while relatively healthy at about 441 million barrels, have been trending lower quickly as global stockpiles shrink. Exxon and Chevron executives have recently warned that inventories are approaching levels where prices can move sharply higher.

For Bakken operators, the current price environment remains robust despite the daily pullback. A WTI price above $90 translates to a Bakken wellhead price in the mid-$80s range, maintaining strong cash flow margins for efficient producers. The ongoing structural tightness in global supply, underscored by the reported plunge in OPEC output, supports a firmer long-term price floor. Operators will monitor the pace of the SPR's eventual refill, as a swift return of borrowed barrels could temporarily soften the market, while a drawn-out process would leave commercial inventories as the primary buffer.

Natural gas prices also moved lower Friday, with the front-month contract down $0.12 to $3.22 per MMBtu.
