Pepper & spices: Cycles

The planting boom that crashed prices in the 2010s

Pepper behaves like other perennial crops. High prices encourage planting, new vines come into bearing several years later, and the resulting glut depresses prices for years. Vietnam's expansion fits this: FAOSTAT output more than doubled between 2010 and 2020, and prices slumped in the late 2010s as the new vines bore fruit. Weather in Vietnam's Central Highlands, India's Kerala and Brazil's Espírito Santo adds year-to-year shocks. Farmers switching land between pepper, coffee and durian also shifts supply.

Super-cycles in pepper & spices

Spices have no published long-run World Bank price series, so cycles are best traced through output and export values. Pepper shows strong planting cycles: high prices draw new vines, especially in Vietnam, and output arrives several years later and crushes prices. World pepper output rose from 0.29 Mt in 1990 to 0.43 Mt in 2010 and 0.89 Mt in 2020 (FAOSTAT), most of the growth from Vietnam. Seed spices and chilli are annual crops with yearly cycles. Cardamom swings with the monsoon in Kerala and the crop in Guatemala. Free long-run price series for these markets are not published.

1. 1990-2010

   Vietnam built a pepper industry from almost nothing, overtaking India as the largest producer and exporter.

   No long-run price series found; Vietnam's output rose from 11 kt (1990) to 105 kt (2010) while India's stayed between 51 and 73 kt (FAOSTAT)

2. 2015-2020

   Vietnamese planting in response to high prices earlier in the decade came into bearing, flooding the market and pushing many growers out.

   World pepper output jumped from 0.57 Mt (2015) to 0.89 Mt (2020) (FAOSTAT); no price series found

3. 2024-2026

   Weather damage in Vietnam and Kerala and stronger demand lifted export prices for pepper and cardamom.

   India's pepper export unit value rose from about Rs 491/kg (Apr-Jan 2024-25) to Rs 608/kg (Apr-Jan 2025-26); small cardamom from Rs 2,195/kg to Rs 2,459/kg as export volume more than doubled (calculated from Spices Board data)

What drives the cycle

• Planting cycles in Vietnam and Brazil. Pepper vines take several years to bear, so high prices bring a supply wave that later depresses prices.
• Monsoon and weather. Kerala's pepper and cardamom and Gujarat's cumin depend on rainfall timing; drought or floods cut output sharply.
• Food safety rules in importing markets. EU and US limits on pesticide residues, aflatoxin and ethylene oxide can block shipments and shift demand between origins.
• Processed food demand. Snacks, sauces and ready meals use oleoresins and blends, raising steady industrial demand.
• Currency and freight. Exports are priced in dollars; the rupee, Vietnamese dong and Brazilian real affect competitiveness.
