Where is the Curve?

August 27, 2026

Ask McKinsey what carbon will be worth in 2031 and you get a projection. Ask a copper trader the price of copper in 2031 and you get a screen: a page of live prices, each one a commitment somebody will honor today for metal delivered years from now. A projection is an opinion. A screen is a market. That difference is why copper mines get financed and carbon projects get grants.

That page of prices is a forward curve, and it is what turns future production into present money. A lender discounts against it. A producer hedges into it. A board approves capital because of it. Every market that finances production years before delivery works this way.

Carbon has prices without a curve. There are thousands of spot prints, bilateral deals with confidential terms, and index estimates assembled from surveys. What there is not is a set of dated, tradable commitments that anyone can see and transact against. Prices are not a curve.

So why has a forward curve yet to form for carbon? A curve is built from standardized forward commitments changing hands, and a forward commitment needs a deliverable: a defined thing, uniform across units, that the seller can be made to hand over and the buyer will accept without renegotiating what it is. Carbon has never been packaged that way. Sold raw, every unit is its own project, methodology, vintage, and jurisdiction, so every trade becomes a negotiation about the underlying rather than about the price.

This is the packaging problem we have been dissecting in this series. A security is a standardized thing by construction: the wrapper defines what the holder owns, uniformly, whatever sits inside it. Credits from different projects and different vintages can be assembled into defined cohorts, and it is the cohort, not the credit, that becomes deliverable. Which is how every other market solved the same problem.

Once cohorts trade forward, a project developer asking what carbon is worth in 2031 is no longer asking for an opinion. They are asking for a quote, and somewhere a dealer is willing to give one. That quote is what a lender lends against, and it is the difference between a project financed on its own production and a project waiting on a grant.

Quality shows up here too, and only here. When everything trades as a single undifferentiated category, better credits are discounted along with the rest. Separate cohorts carry separate curves, and the gap between them is what a premium actually looks like: a number, visible to everyone, that a high-quality producer can point at and a buyer is willing to pay.

The investment frame is what makes a forward curve possible, and the security is how the frame is applied. That is the last part we need. Next week, we’ll assemble the entire instrument in one place.
