Palm Oil Market in September 2026: Analyzing the End-of-Quarter Decline and Macroeconomic Impacts

The global vegetable oil market, particularly palm oil, experienced a volatile September marked by sharp adjustments. From peak levels in the first weeks of the month, palm oil prices reversed course and fell significantly toward the end of the month, creating challenges for import-export businesses and food manufacturers. This article summarizes the detailed price movements of palm oil from September 1, 2026, to September 30, 2026, analyzes the core causes, and evaluates the macroeconomic factors shaping market trends.

1. Overview of Palm Oil Price Movements in September 2026

September 2026 recorded a "high start, low finish" scenario for crude palm oil (CPO) prices on the Bursa Malaysia (BMD) exchange. According to actual data, palm oil prices reached as high as 4,978.00 MYR/ton, the highest level in the past 30 days. However, profit-taking pressure and shifts in fundamental factors pushed prices to their lowest point by the end of the month.

As of September 25, 2026, palm oil was trading at 4,672.00 MYR/ton (equivalent to approximately 26,080,879 VND/ton). Although there was a slight recovery of about 10.00 MYR (+0.21%) in the most recent trading session, the general trend for the final week of September remained downward.

A comparison table of average values provides a deeper insight into the market:

• Average price in September 2026: 4,875.04 MYR/ton (~27,214,326 VND/ton).
• Average price in August 2026: 4,792.48 MYR/ton (~26,753,445 VND/ton).
• Monthly fluctuation range: From 4,672.00 to 4,978.00 MYR/ton.

The decline from 4,898.00 MYR (on September 20) to 4,672.00 MYR (on September 25) in less than a week indicates that market sentiment has become more cautious than ever. In Vietnam, imported palm oil prices have fluctuated accordingly, putting pressure on the cost of goods sold for the confectionery, cosmetics, and animal feed industries.

2. Analysis of Causes Behind Palm Oil Price Volatility

The volatility of palm oil prices in September 2026 was not random but the result of a synergy between internal supply-demand factors and competition from substitute oils.

Pressure from the Peak Harvest Season

September is typically the time when palm oil production in Malaysia and Indonesia—the world's two largest producers—enters its peak harvest period. According to reports from the Malaysian Palm Oil Board (MPOB), palm oil stocks tend to rise sharply as production rates exceed the market's short-term export absorption capacity. When supply is abundant, downward price pressure is inevitable to stimulate demand.

Intense Competition from Soybean Oil

Palm oil and soybean oil are direct competitors in the vegetable oil segment. In September 2026, the soybean harvest in the U.S. proceeded favorably with record-forecasted yields. This pulled soybean oil prices on the Chicago Board of Trade (CBOT) downward. To maintain competitiveness and retain major importers like India and China, palm oil prices were forced to adjust deeper to maintain an attractive discount relative to soybean oil.

Import Demand from India and China Slows Down

Following a period of stockpiling for major festivals at the beginning of the month, importers in India began to slow their purchasing pace. In China, slowing economic growth and shifts in consumer habits have also caused demand for imported vegetable oil to fall short of expectations compared to previous years. The absence of large orders from these two populous markets deprived palm oil prices of a crucial support base.

3. Macroeconomic Influences on Global Palm Oil Prices

Beyond direct supply and demand factors, palm oil prices were also heavily influenced by complex macroeconomic variables during September 2026.

Exchange Rate Fluctuations (MYR vs. USD)

Palm oil is denominated in Malaysian Ringgit (MYR) on international exchanges. In September, the fluctuation of the MYR against the USD directly affected export value. When the Ringgit strengthens against the USD, palm oil becomes more expensive for foreign buyers holding USD, thereby reducing demand and pulling listed prices down. Conversely, the price drops in late September were partly due to exchange rate adjustments as the market anticipated new monetary policies from the Central Bank of Malaysia.

Biofuel (Biodiesel) Policy

The role of palm oil extends beyond food to being a critical feedstock for biofuels. Policies regarding biodiesel blending mandates (such as B40 in Indonesia or new roadmaps in Malaysia) play a key role. In September 2026, news regarding Indonesia's adjustment of palm oil export taxes to support its domestic biodiesel subsidy fund triggered market sentiment waves. Any change in the green energy roadmap in Southeast Asia is immediately reflected in global crude oil prices.

Global Crude Oil Prices

The correlation between palm oil prices and crude oil prices remains very tight. When global crude oil prices fluctuate due to geopolitical tensions or OPEC+ production decisions, palm oil prices often move in the same direction. Palm oil is considered a substitute for petroleum in biofuel production; therefore, when oil prices fall, demand for palm oil for energy purposes also declines, creating downward price pressure on this agricultural commodity.

4. Impact of Palm Oil Prices on the Vietnamese Market

Vietnam is a major importer of palm oil for the food processing and consumer goods industries. Consequently, fluctuations in Malaysia quickly spread to the domestic market.

Cost of Goods for Food and Cosmetics Industries

With the average price in September hovering around 27 million VND/ton, Vietnamese manufacturers of instant noodles, confectionery, and bottled cooking oil are facing slightly higher input costs compared to the previous month (August averaged only about 26.7 million VND/ton). However, the decline at the end of September to 26 million VND/ton provides a positive signal, helping businesses alleviate pressure on finished product pricing in the fourth quarter of 2026.

Household Cooking Oil Market

Vietnamese consumers may not immediately feel the change in global palm oil prices at supermarkets due to supply chain lags and manufacturers' inventory levels. However, if the downward trend continues into October, domestic vegetable oil prices may be adjusted downward or accompanied by more promotional programs to stimulate year-end consumer demand.

5. Outlook and Forecast for the Coming Period

Looking back at data from September 1 to September 30, 2026, we see a palm oil market in a state of "searching for a new equilibrium." Although the average price in September was higher than in August, the sharp downward trend at the end of the month (from 4,898 to 4,672 MYR) shows that sellers are gaining the upper hand.

Short-term forecast: In the first week of October 2026, palm oil prices are likely to continue moving sideways or decline slightly if inventory reports from Malaysia show a strong increase. The current key support level lies around the 4,600 MYR/ton zone. If prices break below this level, the market could enter a deeper correction.

Advice for investors and businesses:

• For manufacturing businesses: Take advantage of the price corrections at the end of September to lock in purchase contracts for the fourth quarter, optimizing production costs before entering the peak Lunar New Year consumption season.
• For traders: Closely monitor export data from inspection companies (such as SGS or ITS) and fluctuations in soybean oil prices in the U.S. to make timely decisions.
• Monitor weather factors: Weather phenomena (such as La Nina), if they appear at the end of the year, could cause heavy rain, affecting harvesting and transportation activities in Southeast Asia; this could be an unexpected factor that pushes prices back up.

6. Conclusion

The palm oil market in September 2026 closed on a low note regarding price but opened up many opportunities for buyers. With a price of 4,672.00 MYR/ton on September 25, the market is reflecting temporary supply surpluses and pressure from global macroeconomic factors. Understanding the causes of volatility and macroeconomic links will help Vietnamese businesses be more proactive in their business planning, ensuring stability and competitiveness in a global commodity market that is always full of surprises.
