The Price of Tea

A tea's price is set twice, and the two settings rarely agree. The first is the auction or private-sale price a garden receives for a given lot: fixed at one moment, by grade and origin, against whatever else is on offer that week (the mechanism is The Auctions; the chain it feeds is How the Trade Works). The second is everything that happens to that same kilogram of value after the gate: currency conversion, export levies, certification premiums, and the long march through blender, packer, and retailer margin before it reaches a shelf.

What fixes a price at the point of sale

Three things decide what a given lot fetches at auction, and none of them is a judgment about whether the tea is "good."

• Grade. A tea's grade is a leaf-size classification, not a quality score, and it is the single most reliable price signal in the trade. The full grading hierarchy, OP through Dust, and the CTC-versus-Orthodox manufacturing split behind it, is documented in A Tea's Grade Is a Size Code, Not a Quality Score.
• Origin and season. The same grade sells for different prices from different origins and different flushes of the same garden, because buyers are pricing a cup, and cups differ by terroir and by which flush of the year produced the leaf. A first-flush Darjeeling lot can sell for many multiples of a later flush from the identical garden, a gap the auction record shows clearly and that the season's bulk income rarely follows.
• What else is on the table that week. An auction is a live clearing mechanism: a lot's price depends on the buyers bidding against each other and against every other lot of comparable grade and origin on offer that same session, not against some fixed reference value. The same tea can fetch a different price a month later purely because the mix of competing lots changed.

The long arc: real terms, not nominal

Read a decade of auction-price tables and tea looks stable: composite prices across Mombasa, Kolkata, and Colombo have held in a narrow nominal band for years. That stability is an illusion created by inflation. Asked in 2022 to summarize two decades of the market¹, Ian Gibbs, chairman of the International Tea Committee, the body that has tracked auction prices since the 1930s, put it in one line: over the prior twenty years there had been no movement, and tea's price, once inflation is stripped out, sat below what was paid a century earlier. The nominal number barely moved across that whole stretch; the real one quietly eroded the entire time.

The mechanism behind the erosion is on the supply side, and the FAO's own reporting² to its Intergovernmental Group on Tea found it in a 2005 market assessment: production growth was outpacing the growth in demand. Smallholders now grow roughly 60 percent of the world's tea and make up two-thirds of a sector employing some 13 million people, by the International Institute for Sustainable Development's 2024 accounting³. They keep adding plantings because tea is one of the few cash crops a small plot of land can grow, a rational choice for any one grower trying to hold income steady on a falling price. Summed across millions of growers making that same rational choice, it adds supply to an already oversupplied market, which is exactly the condition that holds a real price down for a generation rather than letting it recover on its own. World consumption has kept rising over the same stretch, driven mostly by China and India's own growing domestic markets, but supply has simply grown faster, and the auction floor is where that mismatch settles.

Every input to growing and processing tea (fuel, fertiliser, labour, transport) has risen with general inflation across that same period, while the auction price has not kept pace. The result: a grower's income, set almost entirely by a number the grower does not control, has gone nowhere for a generation, while the finished product a shopper buys is insulated from that erosion by a retail price point that is far stickier than any commodity floor.

Where the money goes after the gate

The price a garden receives at the gate and the price a shopper pays at the shelf are set by entirely different mechanisms, and the gap between them is the sharpest fact in the whole trade. Two field studies of the same question put real numbers on the split, and disagree with each other. The fullest treatment of both, with the arithmetic worked through, is Who Makes Money From a Cup of Tea?.

The Assam and Vietnam rows are not on the same footing, and the mismatch matters: the Assam study's grower and collector figures are priced per kilogram of green leaf, the raw pluck, while its factory, wholesaler, and retailer figures are priced per kilogram of made tea, the finished product; it takes roughly four kilograms of green leaf to produce one kilogram of made tea. Put on a made-tea-equivalent basis, growing and collecting together come to somewhere near Rs 18 (about 25 US cents at 2019 rates) a kilogram against the factory's Rs 20.00 (about 28 US cents), a real gap but a modest one, not the four-fold difference the raw per-unit figures suggest at first look. The processing step still captures the largest single cut on that corrected basis, ahead of the land, but by a margin, not a multiple.

The 2021 Thai Nguyen study, measured consistently in net-added-value share throughout, found close to the opposite structure: farmers captured the highest share of the chain's net value, more than the processor and more than thirteen times the collector's share. The two studies agree on exactly one thing worth generalizing: the split is not fixed by anything intrinsic to tea. It is set by how many hands a given country's leaf passes through on the way to a cup, and how much leverage each pair of hands holds in that particular chain, which is why a value-chain finding from one origin cannot be assumed to hold in another.

What both chains share is where the widest single margin usually sits: not at the farm gate, and not, in most markets, with the grower at all. Brands and supermarkets typically take the largest share of what a packaged box of tea sells for, while the estate that grew and plucked the leaf keeps a share in the low single digits, out of which it still pays its workers. The imbalance is structural rather than a market failure in any one country: the grower is a price-taker at the auction floor, while a blender, packer, or retailer sets its own margin on a finished, branded product at a price point that barely moves with that same floor underneath it.

What moves it between one sale and the next

Grade and origin set where a lot sits in the price band; three further forces move the whole band up or down between sales, and none of them behaves the way intuition suggests.

• Currency. Tea is grown and plucked for wages paid in the grower's own currency, then sold, in most major markets, against the US dollar (Mombasa, the world's largest tea auction, has settled every trade in dollars since October 1992, a rule adopted to give buyers a single stable unit across the several African origins it clears, not to shield growers from exchange-rate risk). Whatever the dollar does against the grower's currency between the sale and the payout lands, in full, on the grower's income, in either direction, for reasons that have nothing to do with the harvest. Between 2024 and 2025 the Kenyan shilling strengthened from an average of Ksh144 to Ksh129 to the dollar¹¹, which KTDA said, with weaker demand, mainly explained lower farmer bonuses (see What a Weak Currency Does to a Tea Garden's Earnings).
• Weather. A drought or a storm does not reach a price tag directly; it has to travel a chain, bush to pluck to factory to auction floor, and what happens at the last link, a global auction where buyers can often simply bid on another origin's tea instead, usually decides more than the weather event itself. In Kenya's 2019 drought, the price smallholders received at auction fell by around 17 percent⁹ while the harvest shrank. A shock is a volume problem, a logistics problem, or neither, and each type clears the auction floor differently (see Why a Drought Doesn't Always Raise the Tea Price).
• Export levies. A government does not need to own a garden to take a cut of the crop; it only needs the point where made tea crosses the border. Kenya taxes that moment at 0.8 percent of sale value¹⁰ as of its Tea (Levy) Regulations, 2026; Sri Lanka has taxed it, at a shifting rate, since the 1970s; India taxed it for over a century before dropping the charge. Who pays a border levy on paper and who absorbs it in practice are frequently different questions, since the incidence can shift back up the chain to the grower depending on how much bargaining power each origin's producers hold (see Who Pays the Tea Tax?).

Certification and the premium price

A certification label is a promise about money: that a grower somewhere was paid something extra for that specific leaf, over and above the ordinary market price. The two largest schemes price that promise very differently.

Certification guarantees a garden the right to an extra payment; it does not guarantee a buyer willing to make it, which is why the large majority of certified tea, under either scheme, still clears the market at the ordinary price. A 50-cent Fairtrade premium, applied only to the sliver of production that actually sells on those terms, does not reach far into a value chain where the estate nearest the leaf typically keeps a share in the low single digits of the final retail price. (See What a Certification Label Actually Pays the Tea Grower for the full figures, including Kenya's 2025 attempt to opt certain factories out of the compliance cost entirely.)

Two structures the market does not have

• No futures market. Coffee and cocoa have standing futures contracts on the Intercontinental Exchange¹³; ICE lists none for tea. Tea futures traded in New York on 21 January 1901¹², and the trading was short-lived, according to a paper Prabhat Bezboruah, an Assam tea executive, prepared for the FAO's Intergovernmental Group on Tea. The obstacle he set out is standardization: tea "is heterogeneous both over season and region," so "it would be impossible to define a quality for delivery," and contracts "may have to be tailor made for individual gardens." He recommended an index future on the auction average price of a defined category of tea, which he wrote would remove the structural problems that heterogeneity causes (see Why Doesn't Tea Have a Futures Market? for the full case, including two 2020 academic proposals for a workable contract).
• No cartel since 1955. No coordinated supply-restriction mechanism has governed tea since 1955. From 1933 to 1955 India, Ceylon, and the Dutch East Indies ran a legally binding export-quota cartel that did restrict planting and did move the price, sharply, before it lapsed and was never revived. The Intergovernmental Group on Tea is the one standing body where producing and consuming governments discuss the market today, and it has laid out the supply-and-demand mismatch above in detail without arriving at any binding mechanism to correct it (see The Tea Cartel That Worked).
