Why These Energy Stocks are Losing This Week

In this article, we are going to discuss the energy stocks that are losing this week.

Though the overall market hit its all-time high recently this week, the broader energy sector still managed to outperform it on a weekly basis, with gains of 2.34% between September 18 and September 25.

However, Wood Mackenzie issued a warning to the global oil and gas industry in their latest report, stating that the sector needs to brace for a tough year in 2026, with capital budgets set to decline as firms prioritize financial strength over long-term growth investments.

Tom Ellacott, Senior Vice President of Corporate Research at Wood Mackenzie, stated:

“Oil and gas companies are caught between competing pressures as they plan for 2026. Near-term price downside risks clash with the need to extend hydrocarbon portfolios into the next decade. Meanwhile, shareholder return of capital and balance sheet discipline will constrain reinvestment rates.”

The proposed regulation seeks to cut marine fuel emissions, since the global shipping industry accounts for nearly 3% of the world’s carbon emissions.

Share Price Decline Between Sep 18 – Sep 25: 3.91%

Teekay Tankers Ltd. (NYSE:TNK) provides marine transportation services to the oil industry in Bermuda and internationally.

Teekay Tankers Ltd. (NYSE:TNK) was among the shipping stocks that took a hit this week after a consortium of global shipping operators expressed ‘grave’ concerns about the Net Zero Framework tabled for adoption next month at the United Nations’ International Maritime Organization.

The companies made the following statement regarding the deal, which seeks to speed up decarbonization through a bigger regulatory framework:

“We do not believe the IMO NZF will serve effectively in support of decarbonizing the maritime industry… nor ensure a level-playing field as intended. We believe that critical amendments to the IMO NZF are needed, including the consideration of realistic trajectories… before adoption can be considered.”

The United States has already rejected the deal and has threatened tariffs, visa restrictions, and port levies on countries that support it.
