Note: May 29, 2026 – This is an update to the May 27, 2026 article: Indonesia’s Palm Oil Export Crackdown: 10 Major Exporters Investigated for Under-Invoicing as Wilmar and Musim Mas Named – Full Implementation Delayed to January 2027

JAKARTA / SINGAPORE – May 29, 2026 – Two days after Finance Minister Purbaya Yudhi Sadewa announced the investigation of 10 major palm oil exporters, Wilmar International has issued its first official response. The company disclosed to the Singapore Exchange (SGX) that it has not yet received official notification of the investigation. Wilmar shares dropped as much as 10.5% on May 28, 2026, their biggest one-day percentage loss since February 2012.

This 48-hour update covers Wilmar’s official response and the resulting market impact, the additional companies named by the Finance Minister (Golden Agri and Salim Ivomas Pratama), the government’s statement on potential sanctions (companies will not be closed but must pay dues), the confirmed duration of the investigation (approximately three months), the industry response from three Indonesian palm oil companies awaiting implementing regulations, and the unchanged collapse of fresh fruit bunch prices affecting smallholder farmers.

The Essentials: Who, What, When, Where, Why, How (Last 48 Hours)

• Who: Wilmar International Limited (Singapore-based); Musim Mas Group (Singapore-based); Golden Agri Resources (Singapore-based); Salim Ivomas Pratama (Indonesia-based); PT PP London Sumatra Indonesia Tbk; PT Sinar Mas Agro Resources and Technology Tbk; Indonesia’s Finance Minister Purbaya Yudhi Sadewa; the Attorney General’s Office; the Financial and Development Supervisory Agency (BPKP); the Singapore Exchange (SGX); and smallholder farmers across Indonesia.
• What: Six major developments since May 27, 2026:
  • Wilmar International has officially responded, stating it has not received official notification and is cooperating with authorities
  • Wilmar shares plunged 10.5% on May 28, their biggest drop since February 2012
  • Finance Minister Purbaya has named two additional companies: Golden Agri and Salim Ivomas Pratama
  • The government has stated that companies will NOT be closed but must pay their dues after the investigation
  • The investigation has been underway for approximately three months before the public announcement
  • Three Indonesian palm oil companies have responded, indicating they are awaiting implementing regulations
• When:
  • May 28, 2026 – Wilmar shares drop 10.5% (first trading day following May 26 announcement; Singapore market closed May 27 for holiday)
  • May 28, 2026 – Wilmar issues disclosure to Singapore Exchange
  • May 28, 2026 – Finance Minister names Golden Agri and Salim Ivomas Pratama
  • May 28, 2026 – Government confirms investigation has been underway for approximately three months
  • May 26, 2026 – Deputy Minister Sudaryono meets industry stakeholders; reference prices agreed (previously reported)

  • June 1, 2026 – Phase 1 transition period begins
  • January 1, 2027 – Full mandatory implementation begins
• Where: The investigation covers palm oil exports from Indonesia to international markets, with specific focus on trading companies in Singapore. Wilmar responded from Singapore via SGX disclosure. The policy applies to all Indonesian palm oil exports regardless of destination.
• Why (Immediate Cause): The investigation follows the government’s discovery that export data reported to Singapore was approximately 50% below actual values. Wilmar’s response was triggered by being named in the Finance Minister’s May 26 announcement. The market reaction on May 28 reflects investor concern following the long holiday weekend.
• How (Mechanism): The government’s monitoring system flagged 10 exporters for alleged under-invoicing. The Attorney General’s Office, Finance Ministry, and BPKP are jointly conducting the investigation. Companies exported CPO to trading firms in Singapore at approximately 50% below actual prices, which then resold cargo to the United States and other destinations at marked-up prices.

Specific Updates in the Last 48 Hours (May 27–29, 2026)

1. Wilmar International Issues Official Response – Denies Receiving Official Notification

On May 28, 2026, Wilmar International Limited issued a disclosure to the Singapore Exchange (SGX) responding to the investigation announced by Finance Minister Purbaya on May 26.

Wilmar’s Official Statement:

• The company has not yet received official notification of any investigation regarding suspected under-invoicing or transfer pricing
• Wilmar is working with relevant authorities to understand the government’s concerns
• The company will update the market immediately upon receiving official notification
• The company reiterated its commitment to cooperating with authorities

Key Quote from Wilmar’s Statement: “If and when we receive official notification that Wilmar is under investigation for suspected under-invoicing and transfer pricing of exports, we will update the market accordingly.”

Musim Mas Status: Musim Mas Group, the other major company named by Finance Minister Purbaya, has not immediately responded to requests for comment as of May 29, 2026.

2. Wilmar Shares Plunge 10.5% – Biggest Drop Since February 2012

The Singapore market was closed on Wednesday, May 27, for a holiday. On Thursday, May 28, the first trading day following the Finance Minister’s announcement, Wilmar shares dropped sharply.

Market Impact:

Metric	Value
Share price drop	Up to 10.5%
Price level	S$3.15(approximatelyUS$3.15(approximatelyUS2.47)
Significance	Biggest one-day percentage loss since February 2012
Trading day	May 28, 2026 (first trading day after May 26 announcement; market closed May 27)

Context: CPO futures had already slid on May 21, 2026, amid uncertainty over Indonesia’s export policy, triggering panic selling. The investigation announcement has added further pressure on Wilmar shares.

3. Additional Companies Named: Golden Agri and Salim Ivomas Pratama

Finance Minister Purbaya has now publicly identified two additional companies as among those included in the government’s findings.

Companies Named to Date:

Company	Headquarters	Status as of May 29
Wilmar International Limited	Singapore	Has responded; denies receiving official notification; cooperating
Musim Mas Group	Singapore	No response as of May 29
Golden Agri Resources	Singapore	Named by Finance Minister
Salim Ivomas Pratama (SIMP)	Indonesia	Named by Finance Minister; awaiting regulations
6 other exporters	Various	Names not publicly disclosed

Finance Minister’s Statement: “We have all the data on the 10 largest CPO exporters.” When asked specifically about Wilmar and Musim Mas, he confirmed: “That’s correct.”

4. Government Confirms Investigation Underway for Approximately Three Months

The government has provided new details on the timeline and scope of the investigation.

Investigation Details:

• The investigation has been underway for approximately three months before the public announcement on May 26
• The Attorney General’s Office, Finance Ministry, and BPKP are jointly conducting the investigation
• The government has examined 20 companies so far, focusing primarily on the 10 largest ones

Modus Operandi Confirmed by the Investigation:

1. Companies export CPO to trading companies in Singapore
2. The physical goods are shipped directly to the final destination country (e.g., United States)
3. However, the documentation shows the sale only going to Singapore
4. Prices reported to Singapore are approximately 50% lower than actual values
5. Trading companies then resell to the US and other destinations at marked-up prices

Quote from Finance Minister Purbaya: “So those 10 companies sell to Singapore via trading companies. Actually, the goods go directly there because the ships don’t change, but the paperwork is different.”

5. Government States Companies Will Not Be Closed – But Must Pay Dues

The government is now considering what sanctions to impose on the 10 companies suspected of trade misinvoicing.

What Sanctions Are Being Considered:

Sanction Type	Status
Company closure	NOT being considered
Payment of dues	WILL BE REQUIRED – amount to be determined after investigation
Further penalties	Under evaluation

Quote from Finance Minister Purbaya: “We will see what the best (sanctions) are. But we will not close those companies. They must pay their dues as determined later after the investigation.”

What This Means: The government has emphasized that these companies must “pay their obligations” based on the investigation’s findings, but will not be shut down.

6. Three Indonesian Palm Oil Companies Respond – Awaiting Implementing Regulations

Three major Indonesian palm oil companies have issued statements to the Indonesia Stock Exchange (IDX) indicating they are still waiting for implementing regulations before determining the policy’s impact.

PT PP London Sumatra Indonesia Tbk	LSPP	Awaiting details of new regulation

Price Impact (Unchanged from May 27):

Period	FFB Price (per kg)	Change
Before policy announcement	Approximately 3,800 rupiah	–
After policy announcement	1,500-2,500 rupiah	Down 50-60%

Farmer Impact (Unchanged): According to Mansuetus Darto, chairman of the Indonesian Oil Palm Farmers’ Association (APKASINDO): “Fruit is being left to rot in the fields as the collectors have stopped picking up fruit with trucks, and farmers don’t have their own trucks.”

Government Response (Previously Reported, Unchanged): Deputy Minister of Agriculture Sudaryono met with industry stakeholders on May 26 and confirmed that producers agreed to buy fresh fruit bunches at reference prices set by local governments.

Why This Matters (Updated for May 29)

The Wilmar response, the naming of additional companies, the government’s statement on sanctions, and the market reaction are significant developments that change the landscape described in the May 27 article.

For Wilmar International: The company has now officially responded, stating it has not received formal notification. Its shares dropped 10.5% on May 28, the biggest one-day loss since February 2012. The market has clearly reacted negatively to the investigation announcement. Wilmar is cooperating with authorities and will update the market upon receiving official notification.

For Musim Mas Group: The company has not yet responded to requests for comment as of May 29, 2026. This contrasts with Wilmar’s proactive disclosure to the Singapore Exchange.

For Golden Agri and Salim Ivomas Pratama: These two additional companies have now been publicly named by the Finance Minister as among the 10 exporters under investigation. Salim Ivomas Pratama has responded, stating it is awaiting implementing regulations.

For the 10 companies under investigation: The government has confirmed that the investigation has been underway for approximately three months and that 20 companies have been examined. The government will not close any companies, but they must pay their dues based on the investigation’s findings.

For the palm oil industry in Indonesia: Three major Indonesian companies (SIMP, LSPP, SMAR) have responded to the Indonesia Stock Exchange, indicating they are awaiting implementing regulations. This suggests the industry is still in a holding pattern, unable to fully assess the policy’s impact until detailed regulations are issued.

For smallholder farmers: The collapse of fresh fruit bunch prices to 1,500-2,500 rupiah per kilogram (down from 3,800 rupiah) remains a critical issue. Farmers are leaving fruit to rot in the fields. The government’s agreement on reference prices has not yet been implemented as of May 29.

For investors: Wilmar’s 10.5% share price drop demonstrates that the market views the investigation as a material risk. The analyst assessment that limited near-term impact is expected (as no fees have been introduced yet) may need to be reassessed given the market reaction and the potential for sanctions.

Current Status (As of May 29, 2026)
