Tea prices explained

Every Tuesday in Mombasa, brokers bid on 8–12 million kilograms of African black tea while traders in Karachi and Cairo watch the average price per kilogram as closely as roasters watch ICE Coffee C. Unlike coffee or sugar, tea has no liquid global futures contract on a major exchange. Price discovery runs through weekly origin auctions, exporter offers, and long-term supply contracts denominated in U.S. dollars per kilogram. Kenya is the world’s largest black-tea exporter; China produces more total leaf but consumes most domestically. Pakistan and Egypt are the two largest importers of Kenyan CTC (crush-tear-curl) tea used in strong milk brews. India’s Assam and Darjeeling regions set orthodox and specialty benchmarks at Kolkata auctions. Meanwhile bubble-tea chains and matcha cafés are pulling green-tea demand on a separate track from commodity black tea. This guide explains auction quoting and grade spreads, production geography, import demand cycles, macro and sister-commodity links, exposure limitations, a Harbor Ag soft commodities monitor worked example, an indicator decision table, common pitfalls, and a practitioner checklist alongside our commodities investing overview.

How tea prices are quoted

Global tea trade splits into auction markets (East Africa, India, Sri Lanka) and direct contract sales (China domestic, Japanese sencha, specialty single-estate). The headline “tea price” in financial press usually means the Mombasa Tea Auction average sold price in USD/kg for Kenyan and regional African origin black tea.

Major benchmarks

Mombasa Tea Auction (Kenya) — weekly sales organized by the East African Tea Trade Association (EATTA); average price per kg across all lots is the global black-tea reference; also reports volume sold and unsold carryover.
Kolkata Tea Auction (India) — separate weekly sessions for Assam CTC, Darjeeling orthodox, and other regional marks; Darjeeling first-flush lots can trade at multiples of commodity CTC.
Colombo Tea Auction (Sri Lanka) — Ceylon orthodox and CTC; quality premiums for high-grown vs low-grown leaf.
FOB origin differentials — exporter offers above or below the auction average for specific factory marks and grades (PF1, PD, BP1 in Kenyan grading).
Retail bag tea CPI — lags auction moves by quarters as blenders work through contracted inventory and packaging costs dominate shelf price.

Grades and processing spreads

Processing method drives price more than origin alone:

CTC (crush-tear-curl) — granular pellets for quick extraction in milk-tea cultures; lowest cost per cup; dominates Kenya, Assam bulk export, and tea-bag blends worldwide.
Orthodox whole leaf — rolled intact leaves; slower infusion, higher aroma; Sri Lanka and Darjeeling orthodox command premiums over CTC at the same origin.
Green vs black — same Camellia sinensis plant; green tea skips oxidation. China sets green-tea export prices through provincial markets, not Mombasa. Bubble-tea demand pulls Chinese green and oolong on a separate curve from Kenyan black.
Specialty and GI teas — Darjeeling, Uji matcha, and single-estate lots trade at auction premiums unrelated to commodity averages; not a hedge for bulk CTC exposure.

When reading headlines, confirm whether the move is in Mombasa average all-grades, a specific Kenyan PF1 mark, or a Darjeeling orthodox session. A 15% rally in first-flush Darjeeling does not lift Egyptian import bids for Kenyan CTC the same week.

Supply: Kenya, India, China, and Sri Lanka

Global tea production exceeds 6.5 million metric tonnes of made tea annually. Supply is perennial — bushes produce for decades, but weather, fertilizer cost, and labor availability move yields within each flush season.

Top producers (approximate shares)

China (~47%) — largest producer; consumes most domestically as green tea; export price sets Asian green-tea tone, not Mombasa black.
India (~23%) — Assam CTC for domestic and export; Darjeeling orthodox for specialty; dual harvest peaks (March–May first flush, June–September main).
Kenya (~9% export-focused) — nearly all production is exported; two rainy-season peaks (March–June, October–December); Mombasa auction volume drives global black-tea sentiment.
Sri Lanka (~5%) — Ceylon orthodox brand premium; economic crisis and fertilizer policy in 2022–2023 cut output and lifted auction averages.
Vietnam, Indonesia, Turkey, Argentina — each 2–4%; Vietnam exports lower-cost black tea competing with Kenyan CTC in Middle East and Central Asia.

Yield drivers and calendar

Rainfall timing — drought during flush reduces leaf weight and quality color; excessive rain dilutes cup strength and lowers auction bids.
Fertilizer cost — tea is nutrient-intensive; potash and urea prices feed into farm-gate economics with a 6–12 month lag.
Labor and wages — hand-plucked orthodox requires seasonal pickers; wage disputes in Assam or Kenya can delay factory processing and tighten near-term auction supply.
Currency (KES, INR, LKR) — weaker shilling encourages Kenyan exporters to accept lower USD/kg bids because local revenue rises; stronger rupee can leave Indian tea unsold at auction.
Energy and logistics — factory withering and drying use fuel; Red Sea shipping disruptions raise freight from Mombasa to Karachi and Jebel Ali.

Kenya’s production is the most export-sensitive barometer: track Tea Board of Kenya monthly production and EATTA weekly auction summaries. India’s Tea Board publishes crop data with a lag; Darjeeling volume is tiny but moves specialty headlines disproportionately.

Demand: Pakistan, Egypt, UK, and green-tea growth

Tea demand is habitual and price-inelastic in the short run in major importing countries — consumers reduce quality or switch brands before they stop drinking. Over 12–18 months, blenders adjust CTC share, pack sizes, and origin mix.

Major importers of African black tea

Pakistan (~18% of global imports) — strong milk-tea culture; buys heavily from Kenya at Mombasa; rupee weakness and import duties directly cap bid prices at auction.
Egypt (~8%) — largest per-capita consumer in North Africa; Kenyan and Sri Lankan CTC; currency and subsidy policy move import pace.
United Kingdom, Russia, UAE, Afghanistan, Sudan — blend and re-export hubs; UK retail brands hedge through long-term contracts more than spot auction.

Domestic consumption giants

India and China — produce and consume internally; export surpluses only in strong crop years.
Turkey — highest per-capita consumption; mostly domestic Rize production.

Green tea and bubble-tea channel

Bubble-tea chains and ready-to-drink green beverages pull Chinese and Taiwanese oolong/green on a separate demand curve from Mombasa CTC. Growth in Southeast Asia and North America adds structural green-tea demand but does not substitute kilogram-for-kilogram with Kenyan black exports. Matcha premium tiers trade like specialty coffee, not commodity tea.

Macro links: auction data, stocks, and sister commodities

Tea trades as a labor, weather, and import-budget commodity. Useful signals beyond the farm gate:

EATTA Mombasa weekly report — average price, volume sold, and unsold lots; first release after Tuesday auction.
Tea Board of Kenya production (monthly) — confirms whether auction rallies reflect tight supply or speculative bidding.
Pakistan tea import statistics (monthly) — import volume and CIF value; slowdown often precedes Mombasa price softness by 2–4 weeks.
Egyptian pound (EGP) and Pakistani rupee (PKR) — weaker currencies reduce importers’ USD bid ceiling at auction.
Kenya shilling (KES/USD) — affects exporter willingness to sell at given USD/kg levels.
Indian Tea Board export data (monthly) — Assam CTC competes with Kenya in Middle East; surplus Indian exports cap Mombasa rallies.
Fertilizer price indices — potash and NPK feed into next-season yield expectations.
Red Sea / Suez freight rates — Mombasa-to-Karachi route cost affects landed import economics.
Retail tea bag CPI (lagged) — useful for inflation horizon, not timing auction entries.

Tea correlates weakly with coffee — both are beverage inputs, but separate supply chains and demand pools. Sugar matters for tea cultures that add sweetener; see sugar prices explained for blend-margin context, not direct tea substitution.

How to get exposure: limits of retail vehicles

Vehicle	What you own	Pros	Cons
Physical bulk tea	Stored made tea at origin or warehouse	Direct commodity	Quality degradation, moisture risk; illiquid; no U.S. retail market
Tea plantation equities (India/Kenya listed)	Company owning gardens and factories	Equity liquidity on local exchanges	FX conversion, political risk; tea is one revenue line
Global beverage brands (Unilever, Tata Consumer)	Brand and distribution margin	Liquid ADRs and local shares	Input cost hedged; not pure tea beta
Soft-commodity baskets / ETNs	Often coffee, sugar, cocoa — rarely tea	Diversified soft exposure	Tea weight negligible or zero
Mombasa auction participation	Direct bidding as registered buyer	True price discovery	Requires import license, logistics, minimum lot sizes

There is no U.S.-listed tea-only ETN comparable to coffee’s JO. Most investors gain indirect exposure through consumer staples equities or accept that tea is a physical trade and origin-economy story rather than a futures sleeve. For soft-commodity mechanics see futures contracts explained and commodities investing explained.

Worked example: Harbor Ag soft commodities monitor

Harbor Ag’s desk publishes a monthly soft commodities monitor covering tea alongside coffee and cocoa. The June 2026 tea section template:

Spot check — Mombasa auction average USD 2.38/kg (prior week 2.31); 8-week range USD 2.18–2.52; Kenyan PF1 top marks USD 2.65/kg; Kolkata Assam CTC average INR 212/kg (equivalent USD 2.54/kg); Darjeeling first-flush orthodox session average USD 8.40/kg (specialty, not comparable to CTC).
Balance sheet — Kenya Tea Board projects 2026 output 535M kg vs 2025 520M kg (+3%); India crop on track for normal Assam second flush; Sri Lanka output stable post-fertilizer recovery.
Auction flow — Mombasa sold 9.2M kg of 10.1M kg offered (91% clearance); unsold carryover below 4-week average; Pakistan buyers active on 62% of top lots.
Imports — Pakistan tea imports YTD +4% by volume; Egypt flat; UAE re-export demand firm ahead of Ramadan stocking (historical pattern, not a trading signal alone).
Macro — KES 129/USD (weak, export-friendly); PKR stable after prior-quarter depreciation; Red Sea freight Mombasa–Karachi +8% YoY.
Verdict — no dedicated tea futures sleeve; monitor via Tata Consumer Products and Unilever tea segment notes on input-cost calls. Flag tactical overweight consumer staples if Mombasa average breaks above USD 2.55/kg with sub-85% clearance reversing (demand rejection signal). Trim narrative if average falls below USD 2.15/kg on rising unsold volumes and Pakistan import data turns negative two months consecutive.

The read uses public EATTA auction summaries and Tea Board releases. Rules are written before the month starts — clearance rates, Pakistan import pace, and Kenya production revisions drive decisions, not single-session auction spikes unless confirmed by second-week follow-through.

Indicator decision table

Question	Best signal	Why
Near-term black-tea direction?	Mombasa weekly average USD/kg	Most liquid global benchmark for export CTC.
Demand health?	Auction clearance rate and unsold volume	Below 85% clearance with rising carryover signals buyer strike.
Top importer pulse?	Pakistan monthly tea import volume	Largest Mombasa buyer; leads price by 2–4 weeks.
Supply tightness?	Kenya Tea Board monthly production	Confirms whether rallies are supply-driven or speculative.
Competing origin?	India Tea Board export pace	Assam surplus caps Kenyan premium in Middle East.
Specialty vs commodity?	Kolkata Darjeeling session averages	Orthodox premiums decoupled from CTC; do not hedge each other.
Green-tea demand?	China customs green-tea export data	Bubble-tea channel; separate from Mombasa.
Cost pressure?	Potash and urea price indices	Fertilizer feeds next-season yield expectations.
Importer affordability?	PKR and EGP vs USD	Weaker currencies cap USD/kg bids at auction.
Retail pass-through?	CPI tea sub-index (lagged)	Inflation horizon, not auction timing.

Common pitfalls

Treating Darjeeling like CTC — specialty orthodox auctions move on microclimate and GI rules; they do not predict Mombasa bulk prices.
Ignoring clearance rate — a high average on thin sold volume with large unsold carryover is a weak rally.
Single-week auction noise — Ramadan stocking, factory maintenance, and holiday closures distort one session; require two-week confirmation.
Assuming coffee-tea correlation — beverage cousins with separate supply chains; pairing them in a “soft drink” basket misstates risk.
Missing currency effects — flat USD/kg with weakening KES still raises farmer revenue and can encourage supply expansion.
Retail price as leading indicator — tea bag shelf prices lag auction by quarters; do not use CPI to time origin trades.
Green-tea headline confusion — matcha and bubble-tea growth stories rarely lift Kenyan black-tea export bids.
Searching for a tea ETN — no liquid U.S. pure-play; plantation equities carry FX and governance risk unrelated to auction averages.

Practitioner checklist

Track EATTA Mombasa average, volume sold, and clearance rate every Tuesday.
Separate CTC commodity signals from orthodox specialty sessions.
Monitor Pakistan and Egypt import statistics monthly.
Watch Kenya Tea Board production against prior-year flush timing.
Compare Kolkata Assam averages when Middle East blend economics shift.
Include KES, PKR, and EGP in any USD/kg fair-value model.
Flag fertilizer cost trends 6–12 months ahead of yield impact.
Confirm auction moves with second-week follow-through before acting.
Use beverage equities for indirect exposure; size as staples, not commodities.
Document rules before the month starts; avoid reacting to single headlines.

Key takeaways

No global tea futures — Mombasa weekly auction average USD/kg is the black-tea benchmark.
CTC vs orthodox — processing grade drives price more than country alone.
Kenya exports, Pakistan imports — the dominant bid-ask pair for commodity black tea.
Green tea is a separate market — bubble-tea demand pulls Chinese origin, not Mombasa CTC.
Retail exposure is indirect — plantation and consumer-brand equities, not ETNs.
