Why are oil and gas companies not increasing investment despite generating nearly $500 billion in upstream cash flow in 2026?

Because capital discipline remains exceptionally strong: companies set annual capital budgets based on an assumed Brent price of ~$60/bbl, and even though the actual H1 2026 average reached $91/bbl—generating $495B in upstream cash flow—they chose not to revise spending plans; instead, they prioritized retaining cash on balance sheets, maintaining financial flexibility, and avoiding new large-scale projects due to skepticism about the sustainability of current high prices—which are driven by geopolitical conflict rather than robust demand growth.

What long-term production challenge is looming for the global oil and gas industry, and how does current investment behavior exacerbate it?

From 2030 to 2040, the 155 tracked oil and gas companies face an average 30% natural production decline—equivalent to 32 million barrels of oil equivalent per day (excluding Middle Eastern NOCs)—with over 70 companies expecting declines of 50% or more; yet current reinvestment rates have fallen to roughly half of 2015 levels, meaning the industry is deferring the massive new project investments needed just to offset this decline, thereby risking a future supply crunch despite today’s cash accumulation.
