The development of crude oil prices on the global market is always a major concern for various parties, from producers to consumers. In 2023, oil prices experienced significant fluctuations, influenced by various factors including geopolitics, global demand and energy policy. According to the latest report from OPEC, in September 2023, Brent oil prices will reach around $90 per barrel, while WTI will be around $85 per barrel. One of the main factors influencing oil prices is geopolitical tensions, especially those in the Middle East and Europe. Conflicts and uncertainty in large oil producing countries, such as Saudi Arabia and Russia, often cause price spikes. For example, attacks on oil infrastructure in Saudi Arabia last year resulted in sharp price spikes, the effects of which are still felt today. Global demand also plays a crucial role in determining crude oil prices. With the post-COVID-19 pandemic economic recovery, energy demand is increasing, especially in countries such as China and India. Data from the International Energy Agency (IEA) shows that world oil consumption is expected to grow by 3% in 2023, adding pressure on supply. In addition, the steps taken by oil producing countries to maintain market balance also affect prices. OPEC+ has agreed to cut production to support prices. In August 2023, they announced additional production cuts of 1 million barrels per day, which contributed to strengthening oil prices. The impact of sustainable energy policies cannot be ignored. Many countries are now switching to renewable energy sources and making efforts to reduce carbon emissions. This transition has the potential to reduce dependence on crude oil, but also creates long-term uncertainty regarding prices. Investors are now considering the risks associated with a greener energy future in their strategies. Another factor to consider is financial market volatility. Oil prices are often affected by exchange rate fluctuations, which can result in significant changes in global energy costs. Over the past few months, monetary policy changes by the US Federal Reserve, including interest rate increases, have had a major impact on the value of the US dollar and, in turn, oil prices. In conclusion, the latest developments in crude oil prices on the global market are strongly influenced by a combination of geopolitical tensions, consumer demand, OPEC+ production policies, and a greener energy transition. With continued uncertainty, market participants must continue to monitor these factors to predict future price trends.
