The International Energy Agency (IEA) has highlighted significant risks to global oil and gas stability, driven by both natural production declines and geopolitical volatility. An earlier analysis noted that global production faces an average annual decline rate of nearly 6%, suggesting that without substantial investment in new conventional fields, natural declines could reduce global oil production by approximately 8% per year.

By October, IEA Executive Director Fatih Birol warned that there is no “credible pathway” for the oil market to normalize by 2027. This outlook is compounded by regional conflicts in the Middle East and concerns regarding the reliability of the Strait of Hormuz. While the agency has mobilized approximately 20% of available strategic reserves to address supply difficulties, it maintains that 80% of reserves remain available to mitigate potential shortages.
