Brent Crude Oil Market September 2026: Supply Pressure and the Race to Surpass $95/Barrel

Entering the first days of September 2026, the global energy market is witnessing dramatic fluctuations in Brent crude oil prices – the benchmark for two-thirds of the world's crude oil. Following a volatile August marked by alternating gains and losses, Brent oil prices have officially established a new price floor, significantly higher than the levels seen at the beginning of the third quarter of 2026. This article summarizes detailed price data, analyzes core causes, and provides a macroeconomic outlook on Brent oil price trends for the period from September 1, 2026, to September 30, 2026.

1. Overview of Brent Crude Oil Price Movements in Vietnam and Globally

As of the close of the final trading session of August (August 31, 2026), the global Brent crude oil price stood at $90.74/barrel. In the Vietnamese market, this price is equivalent to approximately 2,366,336 VND/barrel (based on the reference exchange rate). Compared to the previous trading session, the oil price recorded a slight increase of about $0.02, corresponding to a growth rate of 0.0198%.

Looking back at the overall picture of the past month, we see a clear upward trend:

• Average price for the current month (August 2026): $88.11/barrel (approximately 2,297,750 VND).
• Average price for the previous month (July 2026): $83.97/barrel (approximately 2,189,786 VND).
• 30-day fluctuation range: Lowest at $79.36 and highest at $94.39/barrel.

The difference between the average prices of the last two months (an increase of over $4/barrel) indicates that the market is in a strong upward cycle. Notably, the fact that oil prices touched the $94.39/barrel threshold at the end of August (August 22-23) has created expectations that oil prices could soon return to the $100 mark in September if macroeconomic conditions continue to tighten.

2. Analysis of Causes for Price Fluctuations in the Final Trading Week of August

The movement of Brent oil prices in the final days of August and early September is not coincidental. There are three main groups of causes leading to the fluctuation from the peak of $94.39 to the current $90.74:

Supply Regulation Strategy from OPEC+

The OPEC+ alliance, led by Saudi Arabia and Russia, continues to maintain its stance of tightening supply to keep oil prices at levels beneficial to national budgets. Leaked reports at the end of August suggest the possibility that this alliance will extend its voluntary production cuts through the end of the fourth quarter of 2026. This pushed oil prices to soar above $94 in the fourth week of August.

Profit-Taking Activities by Investors

After Brent oil prices rose continuously and hit their highest level in many months ($94.39), profit-taking pressure emerged. In trading sessions from August 24 to August 31, hedge funds and financial investors executed sell orders to realize profits, causing oil prices to correct toward the $90 range. This is seen as a necessary "rest" for the market before entering a new wave.

Crude Oil Inventory Situation in the US

Data from the US Energy Information Administration (EIA) shows that US commercial crude oil inventories fell more sharply than expected in the final week of August. As inventory levels decrease, concerns about energy security rise, directly supporting the upward momentum of Brent oil prices even though the USD has at times strengthened significantly.

3. Analysis of Macroeconomic Influences on Brent Crude Oil Prices in September 2026

In September 2026, Brent crude oil prices will be strongly influenced by global macroeconomic factors. Understanding these factors is key to accurately forecasting the market's direction.

Monetary Policy of the US Federal Reserve (Fed)

September is typically a time when the Fed makes important decisions regarding interest rates. If the Fed decides to pause interest rate hikes or begin a path of slight cuts to support economic growth, the USD will weaken. Since oil is priced in USD, a weaker greenback makes oil cheaper for countries using other currencies, thereby stimulating demand and pushing oil prices up.

Health of the Chinese Economy

China remains the world's largest importer of crude oil. Economic data on China's Purchasing Managers' Index (PMI) and retail sales released in early September will be a compass for energy consumption demand. If Beijing's economic stimulus packages take effect, crude oil demand will increase sharply, providing a push for Brent prices to break through the $92 resistance level.

Geopolitical Tensions and Transport Risks

Geopolitical hotspots in the Middle East and Eastern Europe still harbor many risks of supply chain disruptions. Any incident related to vital maritime routes such as the Strait of Hormuz or the Suez Canal could cause Brent oil prices to "dance" with a range of $5-10 in just a few trading sessions.

Seasonal Factors: Transition Between Summer and Winter

September is the end of the peak driving season in the US and Europe, but it is also the time when countries begin to stockpile heating oil for the upcoming winter. This transition usually creates a buffer for oil prices, preventing deep price drops.

4. Market Outlook and Price Forecast for Brent Oil for the Week of September 1 - September 30, 2026

Based on actual data and macroeconomic analysis, we provide the following scenario for Brent crude oil prices in September:

Base Scenario (60% probability): Brent oil prices will fluctuate between $88.00 - $95.00/barrel. The market will trade sideways in the first week of the month to absorb news regarding OPEC+ production. Subsequently, prices will gradually climb as futures contracts for the winter are pushed higher. The current price of $90.74 is considered a solid foundation.

Positive Scenario (25% probability): If there are unexpected supply incidents or escalating geopolitical tensions, oil prices could completely break the $95 threshold and head toward the $100/barrel mark. This would put extreme pressure on global inflation.

Negative Scenario (15% probability): If economic data from major economies (US, China, EU) is worse than expected, concerns about recession will outweigh concerns about supply shortages, pulling oil prices back to the $80 - $85/barrel range.

5. Impact of Brent Oil Prices on the Vietnamese Economy

The fluctuation of Brent oil prices at levels above $90/barrel brings both opportunities and challenges for the Vietnamese economy in September 2026:

• For the state budget: Vietnam is both a crude oil exporter and an importer of finished petroleum products. High oil prices help increase revenue from crude oil exports and resource taxes.
• For domestic gasoline prices: With Brent prices maintained around $90.74, the pressure to adjust gasoline prices upward during the operating periods of the Ministry of Industry and Trade and the Ministry of Finance is very high. It is forecast that domestic gasoline prices may have 1-2 upward adjustments in September if the stabilization fund is not used aggressively.
• Logistics costs and inflation: High oil prices directly push up transport costs, thereby having a chain reaction on the prices of consumer goods. Transport and manufacturing businesses need to proactively have fuel cost contingency plans to protect profit margins.

6. Advice for Investors and Businesses

In the context of Brent oil prices being in a sensitive range, energy investors need to be extremely cautious. Closely monitoring weekly EIA reports and announcements from OPEC+ is mandatory.

For businesses heavily dependent on fuel, September 2026 is an appropriate time to consider price hedging contracts to fix input costs, avoiding price shocks if the market approaches the $100 mark.

Conclusion: The Brent crude oil market in September 2026 promises to be a vibrant period with an upward trend still dominating. The price of $90.74/barrel is not just a number, but an expression of a market that is tightening and full of expectations. Let's wait and see if the macroeconomic decisions this month are strong enough to help "black gold" conquer new heights.
