1. Overview: Indonesia in the Global Coffee Market

Indonesia is the world’s fourth-largest coffee producer, after Brazil, Vietnam, and Colombia, and ahead of Ethiopia and Uganda. Approximately 75 percent of Indonesian coffee production is exported. Robusta accounts for nearly 88 percent of total output, making Indonesia the largest Robusta producer in Asia and a key supplier to European and US markets.

According to the USDA FAS report from the Jakarta office, Indonesia’s coffee sector faces significant climate-related challenges. Excessive rainfall during the flowering and fruit development phases in late 2025 and early 2026 has severely damaged Robusta crops in southern Sumatra and Central Java. Meanwhile, Arabica-growing areas in Aceh and North Sumatra are still recovering from floods and landslides caused by Typhoon Sinyar in November 2025.

Key insight: Robusta dominates Indonesian coffee production at 88 percent. Smallholders farming 1-2 hectares represent about 98 percent of total coffee area, making the sector highly vulnerable to weather shocks and infrastructure disruptions.

2. Production Forecast: MY 2026/27

FAS Jakarta forecasts Indonesian coffee production for MY 2026/27 at approximately 11.38 million 60-kg bags (682,800 metric tons), comprising 1.38 million bags of Arabica (82,800 tons) and 10.00 million bags of Robusta (600,000 tons). This represents an 8 percent decline from the revised 2025/26 estimate of 12.37 million bags.

3. Climate Challenges: Rains and Typhoon Damage

The main driver of Indonesia’s production decline is abnormal rainfall during flowering and fruit development. In mid-2025, excessive rains disrupted Robusta flowering in the southern Sumatra highlands. In Central Java, farmers reported heavy rains that caused flowers to drop and pollen to wash away, interrupting pollination and reducing fruit set.

In Aceh and North Sumatra, Arabica areas continue to suffer from flooding caused by Typhoon Sinyar in late November 2025. As of April 2026, infrastructure recovery remains incomplete, keeping transport costs high. Several processing facilities and warehouses were also damaged. Some Arabica plantations may need 2-3 years to recover. The main harvest in Aceh, normally from October to November, was delayed into early 2026.

Looking ahead, Indonesia’s National Weather Agency (BMKG) projects that the 2026 dry season will be significantly drier and longer than average due to a weak El Niño expected to strengthen to moderate levels in the second half of 2026. In Sumatra, the dry season will begin in April-May 2026, starting in Aceh and North Sumatra, then spreading to Lampung and South Sumatra, peaking around August 2026. El Niño conditions typically increase drought risk, which can further disrupt flowering.

4. Yield Projections

For MY 2026/27, Robusta yields are expected to decline due to rainfall disruptions, though the report did not provide specific yield per hectare figures. Historically, Indonesian Robusta yields remain below one metric ton per hectare and vary significantly by region. Arabica yields in Aceh and North Sumatra are expected to stay low until infrastructure and farms recover.

Adoption of improved, higher-yielding seedlings remains limited because most farmers rely on locally sourced planting material. Government distribution of subsidized seedlings and farmer training programs also remain limited in geographic coverage.

5. Price Dynamics: Decline from 2025 Peaks

Farmgate and spot prices for both Robusta and Arabica have declined significantly from their 2025 highs. According to spot price data from Lampung (Robusta) and Medan (Arabica), prices have moderated due to improved global supply expectations and weaker demand from some roasteries.

Robusta spot prices in Lampung peaked above 104,000 IDR/kg in February 2025 but fell to around 66,661 IDR/kg by April 2026, a drop of roughly 36 percent from the peak. Year-on-year (April 2025 to April 2026), Robusta prices fell 32 percent. Compared to October 2025 (84,128 IDR/kg), the decline is about 21 percent.

Arabica spot prices in Medan peaked above 229,835 IDR/kg in November 2025 but fell to around 174,162 IDR/kg by April 2026, a drop of roughly 24 percent from the peak. Compared to October 2025 (219,802 IDR/kg), the decline is about 21 percent.

6. Export Outlook: Lower Supplies, Stronger European Demand

FAS forecasts green bean exports for 2026/27 at 7 million bags, down 11 percent from 2025/26, due to lower exportable supplies and continued strong domestic demand. Total exports (including roasted and soluble) are forecast at 8.05 million bags.

Despite the overall decline, shipments to European markets rose 72 percent to 2.4 million bags in 2025/26 compared to the previous year. This reflects renewed demand for Indonesian beans, particularly from Belgium and Germany, supported by recovered supplies, competitive pricing, and EUDR compliance readiness.

The United States remains among Indonesia’s top five destinations, with steady demand between 680,000 and 950,000 bags over the past five years. In 2025/26, shipments to the US ranked third at 797,000 bags. These shipments typically consist of 60-80 percent Arabica beans, mostly exported through the Port of Belawan in North Sumatra.

7. Trade Agreements and Policy Environment

Unlike India, Indonesia has no newly ratified free trade agreements specifically targeting coffee exports to Europe. However, the country continues to benefit from existing Generalized System of Preferences (GSP) facilities. Exporters have reported higher freight costs and shipping delays linked to the Middle East conflict in the last quarter of 2025/26, which affected some shipments.

Rupiah depreciation against the US dollar supported stronger demand toward the end of 2025/26. Prices for lower-grade Arabica strengthened through March 2026 as access improved, though transport costs reportedly doubled in affected areas.

8. Domestic Consumption: A Growing Market

FAS forecasts domestic consumption for 2026/27 at 4.83 million bags (289,800 metric tons), up 20,000 bags from the previous year, supported by continued demand from roasteries and processors. Local roasteries have faced squeezed margins as green bean prices rose since 2024, and weaker purchasing power in 2025/26 shifted some demand toward low- to medium-grade coffee. With green bean prices easing in early 2026, demand from roasteries should remain strong.

At the consumer level, low-priced coffee sold by street vendors remains popular among workers and low- to middle-income consumers. Coffee outlets in public venues serve higher-end consumers, including Gen-Z. Kopi susu (coffee with milk) remains a popular entry-level drink, widely available in coffee shops and ready-to-drink products.

9. Long-Term Vision and Recovery Outlook

Indonesia has no publicly stated long-term production target comparable to India’s 2047 vision. However, the government and the Coffee Board of Indonesia (under the Ministry of Agriculture) have promoted sustainability programs and EUDR compliance support. The BMKG’s El Niño forecast for the second half of 2026 poses additional risks. Recovery for Arabica plantations in Aceh is expected to take 2-3 years, while Robusta areas may rebound in 2027/28 if normal rainfall returns.

10. Imports: Filling the Gap

FAS forecasts green bean imports for 2026/27 at 1.42 million bags (85,200 metric tons), up slightly from 1.415 million bags in 2025/26. Indonesian green bean imports are closely tied to production and local demand, jumping from around 230,000 bags in 2020/21 to a peak of 942,000 bags in 2023/24, then dropping to around 372,000 bags in 2025/26. The 2023/24 spike reflects weak domestic supply and strong demand for specialty beans and the growing ready-to-drink sector.

Green beans account for approximately 94 percent of total imports and are primarily sourced from Nicaragua, Vietnam, Brazil, and Kenya for processing and re-export.

11. Key Challenges Facing Indonesian Coffee Sector

• Climate variability: Excessive rains during flowering (mid-2025) followed by El Niño drought (late 2026) create extreme weather shocks.
• Infrastructure damage: Typhoon Sinyar destroyed roads, bridges, processing facilities, and warehouses in Aceh and North Sumatra. Recovery remains incomplete as of April 2026.
• Smallholder vulnerability: 98 percent of coffee area is farmed by smallholders with limited access to credit, improved seedlings, or crop insurance.
• Fertilizer costs: Rising input costs and fertilizer supply uncertainty continue to pressure farmer margins.
• Freight disruptions: The Middle East conflict has increased shipping costs and caused delays, affecting export competitiveness.
• Limited replanting programs: No major replanting or expansion programs have been implemented recently, leaving aging trees in place.

12. Opportunities

• EUDR preparedness: Indonesian exporters have prepared for EU deforestation regulations, potentially gaining market share in Europe.
• Growing domestic market: Rising coffee culture among Gen-Z and the popularity of kopi susu and ready-to-drink products.
• Soluble coffee demand: Domestic soluble consumption is projected to remain strong at 1.55 million bags.
• Rupiah depreciation: A weaker rupiah supports export competitiveness despite lower prices.
• Recovery potential: Once infrastructure is rebuilt and rainfall normalizes, Indonesian Robusta production can rebound quickly.
