Introduction  

The Organisation of the Petroleum Exporting Countries (OPEC) has long been central to the global energy market. Economist J.D. Hamilton described the post‑1973 period as the “age of OPEC”, which reflects the organisation’s influence over oil prices and production policy. After nearly sixty years as a member, the UAE has decided to leave OPEC- a move that may signal a shift in the global energy landscape.

This decision seems to reflect the changing economic goals and the UAE’s focus on diversifying the economy. As geopolitical dynamics change and the global energy market evolves, OPEC's production limits may no longer align with the country’s long-term plans.

History of OPEC

The Organisation of the Petroleum Exporting Countries (OPEC) is an intergovernmental organisation created by the five founding members of Iran, Iraq, Kuwait, Saudi Arabia and Venezuela. This organisation aims to coordinate and unify petroleum policies among member countries. This ensures fair prices for petroleum-producing countries and an efficient supply of petroleum for other nations.

The 1970s oil crisis cemented OPEC’s influence over international pricing. However, in recent decades, the organisation has faced various challenges including oversupply, market volatility and geopolitical tensions.  

Why is the UAE leaving OPEC
The UAE expanded its production capacity through Abu Dhabi National Oil Company (ADNOC) and aims to reach 5 million barrels of oil per day by 2027. OPEC's quota system restricts how much oil the UAE can produce, regardless of its increased capacity. Leaving OPEC removes these limits, allowing the UAE to maximise output during periods of high global demand and geopolitical uncertainty.

The UAE is also accelerating economic diversification by investing in sectors such as aviation, logistics, tourism, AI and manufacturing. Oil is no longer the sole driver of its economy.  The UAE’s departure from OPEC could affect 12 per cent of OPEC’s total oil output.

A major Gulf producer stepping away from OPEC suggests that national economic priorities now outweigh collective market management. An increase in Emirati production could bring down oil prices, benefiting energy-importing countries but increasing competition among producers. This weaker collective management may result in greater market volatility in times of geopolitical uncertainty.

Future Outlook

The UAE's exit from OPEC might be more than just a single geopolitical decision. It may indicate a gradual shift from unified oil coordination towards a more competitive energy market. 

Although oil could remain globally significant for many years, the UAE appears to be increasingly prioritising the use of current earnings to support long-term economic diversification and technological advancement. Should other leading producers emphasise national autonomy over collaboration, the "era of OPEC" may gradually give way to a new phase in global energy markets.
