Oil is an essential resource powering industries and economies around the world. The industry is dominated by large multinational corporations, such as Exxon Mobil Corporation (NYSE:XOM), BP p.l.c. (NYSE:BP), Shell plc (NYSE:SHEL), and Chevron Corporation (NYSE:CVX), which account for a significant portion of global oil production. However, there are also numerous smaller companies, both public and private, involved in various aspects of the oil industry. The integral role it plays in the overall economy of a country is the reason why many countries have nationalized their oil sector to exercise more control over oil reserves. Some of the largest state-owned oil companies include PetroChina, Rosneft, and Petroleos de Venezuela.
Russia’s war on Ukraine saw global oil prices soaring oversupply concerns. As European countries looked for alternatives to their energy imports and the West put sanctions on Russia, the markets soon realized that there might be a shortage of supply in the market, with Russia being a major oil producer. Hence, the brent oil price crossed $100 for the first time after 2014 in 2022. However, with the start of the Fed hiking cycle and a slowdown in global economies, the oil demand has slowed down in recent months and has come down below $100 in 2023. However, with China opening up and relaxing COVID restrictions, the global oil demand is expected to gain strength in the near term.
As per IEA, global oil demand is projected to increase by 1.9 mb/d, reaching a total of 101.7 mb/d in 2023, with a significant portion of the growth coming from China after the easing of Covid-related restrictions. On the other hand, the global oil supply growth is expected to decelerate to 1 mb/d after last year’s 4.7 mb/d growth led by OPEC+. OPEC has also increased its forecast for global oil demand growth in 2023, primarily due to the relaxation of COVID-19 restrictions in China. As per OPEC, Chinese demand will grow by 590,000 barrels per day in 2023. The supply-side is expected to remain tight in 2023 with the organization reducing its supply forecasts for non-OPEC producers, which could lead to a tighter market and support oil prices.

The Renewable Energy Factor
The global oil and gas industry is going through a major transition, driven by the climate change emergency. As per BP, global oil demand is expected to reach a peak level near the 2030s as the Russian invasion of Ukraine has accelerated efforts towards sustainable and clean energy. Governments around the world are now seeking to improve energy security by increasing the proportion of renewables in their energy mix.
Due to the implementation of supportive policies, O&G companies have been able to raise their investments in clean energy, which is expected to fast-track the transition towards clean energy. The United States has passed two acts between 2020 and 2022, namely the Infrastructure Investment and Jobs Act (IIJA) and the Inflation Reduction Act, which provide for approximately $450 billion of clean energy and related investments. Additionally, the Securities and Exchange Commission (SEC) has proposed rules that require companies to disclose their emissions in their SEC filings. Moreover, The European Commission has approved two plans, namely the Fit for 55 climate package and Europe’s REPowerEU plan, which together provide nearly €300 billion in provisions for the clean energy transition and emissions reduction.
