The geopolitical risk premium that had built up in oil markets during the war—which at one point pushed Brent crude above $126 per barrel in May —rapidly evaporated. By the start of the trading week, Brent crude futures had tumbled about 4.6% to roughly $83.30 a barrel, while West Texas Intermediate (WTI) crude fell by a similar amount, erasing the last of the conflict-era price surge . For an integrated oil major like Shell, a decline in the global crude benchmark directly translates into lower expected revenue and earnings from its upstream production segment.
The plunge in oil prices triggered a broad, indiscriminate sell-off across the entire energy sector in pre-market trading. Shell was not the worst hit. While its U.S.-listed shares dropped over 3%, European peer TotalEnergies fell more than 4%, Equinor dropped over 4%, and BP declined by about 3.7%. U.S. giants Exxon Mobil and Chevron also fell over 2% each during the same period .
This sell-off was exacerbated by a broader market rotation. News of the peace deal caused a wider market rally, with equities and bonds jumping as investors' appetite for risk returned . The result was a flow of capital out of defensive sectors like energy—which had been beneficiaries of high oil prices—and into cyclical and growth-oriented names seen as bigger winners from reduced geopolitical tensions. Shell and its peers were on the wrong side of this rotation, facing selling pressure even as the broader indexes moved higher.
Just days before the oil price crash, Shell had announced a temporary suspension of its $3 billion share buyback program on June 12, 2026. The company stated the pause would last from that day through the market close on July 14, 2026, aligning with the date of a crucial shareholder vote for its $16.4 billion acquisition of Canadian energy company ARC Resources .
The pause was not a sign of financial trouble. It was a regulatory necessity. Under securities laws, the publication of ARC Resources' shareholder circular triggered a required quiet period for Shell, preventing the company from actively repurchasing its own shares . Shell expects that any shares not bought during the suspension will be rolled into subsequent repurchase programs for the remainder of 2026, pending board approval .
However, the timing could hardly have been worse. Corporate share buybacks reduce the number of outstanding shares, helping to support earnings per share and often placing a floor under a stock's price. By removing this technical support, Shell's stock became more vulnerable to the exact macroeconomic shock that arrived with the U.S.-Iran peace deal. The buyback pause left the shares fully exposed to the broad-based energy sell-off, amplifying the pre-market decline .
