Updated for the 2026-2027 CFA® Level II curriculum.
Bonds and equities are financial claims with contractual or residual cash flows. Commodities are physical assets with no cash flow of their own. This distinction drives nearly every valuation question CFA Level II asks about commodities.
Quick Answer
Commodities are valued differently from equities and bonds because they generate no contractual cash flows. Coupon-bearing bonds pay interest; zero-coupon bonds provide a contractual maturity payment. Equities may pay dividends tied to company earnings. A commodity's price depends on physical supply, demand, storage cost, financing cost, and convenience yield, the benefit of holding physical inventory. A dividend discount model cannot be applied to the commodity itself.
Key Takeaways
Bonds and equities are financial claims on future cash flows. Commodities are physical assets with no cash flow claim attached.
Commodity prices reflect current and expected physical supply and demand, not a discounted payment stream.
Carrying costs, including storage, insurance, and financing, raise the cost of holding physical inventory over time.
Convenience yield is a noncash benefit of holding physical inventory. It is not a cash distribution.
Owning a commodity-producing company is not the same as owning the commodity. Equity value depends on operating costs, debt, and management decisions in addition to the commodity price.
What You Need to Know for CFA Level II
The LOS requires a direct contrast between commodity valuation and the valuation of equities and bonds.
Bonds are valued by discounting contractual coupon and principal payments at an appropriate yield.
Equities are valued by discounting expected dividends or by assessing a residual claim on company earnings.
Commodities have no contractual cash flow, so a standard discounted cash flow model does not apply to the physical asset.
Carrying cost and convenience yield help explain commodity price relationships over time. They do not determine every observed spot price on their own.
Candidates must separate the value of a commodity from the value of a company that produces that commodity.
How Commodities Are Priced Compared With Equities and Bonds
A bond gives the holder contractual repayment rights. Coupon-bearing bonds also promise interest payments; zero-coupon bonds concentrate repayment at maturity. An equity share gives the holder a residual claim on company earnings, often distributed as dividends. Both securities can be valued by discounting expected future cash flows to the present.
A commodity is a physical asset. Holding a barrel of oil or a ton of copper creates no contractual right to any future payment. The commodity pays no interest and declares no dividend. Its price reflects current and expected physical supply and demand. Storage, financing, and the value of immediate access help explain the economics of holding inventory.
This matters because candidates sometimes apply a dividend discount model or a bond pricing model to a commodity. That approach fails because there is no cash flow for the model to discount. Commodity valuation instead depends on production levels, inventory levels, weather effects, supply disruptions, and demand from industrial users.
A related distinction separates the commodity from the company that produces it. A mining company's equity value depends on its copper output, extraction cost, debt level, and management decisions. The copper itself has none of these features. Its value depends only on physical market conditions for copper.
Carrying costs and convenience benefits
Carrying cost is the cost of holding a physical commodity over time. It includes storage, insurance, and financing cost on the capital tied up in inventory.
Convenience yield is the nonmonetary benefit of holding physical inventory rather than a forward contract on the commodity. A manufacturer that keeps raw material on hand avoids a production stoppage if a shipment is delayed. That benefit has value, even though no cash changes hands.
Convenience yield often rises when available inventories become scarce because immediate access becomes more valuable. Carrying costs depend on financing rates, insurance, storage capacity, and other expenses. They need not move in the opposite direction: scarce storage space can raise costs even while a physical shortage raises convenience benefits.
This note keeps the carrying cost relationship conceptual. Futures curve shapes, including contango and backwardation, belong to a separate study note on commodity futures pricing.
Working Example
An analyst compares three assets. Asset 1 is a five-year corporate bond paying a 4% annual coupon. Asset 2 is equity in a mining company that pays dividends from copper sales. Asset 3 is a physical warehouse holding of copper.
Step 1: Identify the valuation input each asset requires.
Bond: coupon rate, maturity, principal, and a discount rate reflecting credit risk.
Equity: expected future dividends, an earnings growth rate, and a required return on equity reflecting the mining company's business risk.
Copper: current spot price, physical supply and demand conditions, storage cost, financing cost, and convenience yield.
Step 2: Explain why the copper does not pay the mining company's dividends.
The mining company's dividend comes from selling copper at prevailing prices after covering extraction cost, operating expense, and debt service. Physical copper carries no contractual claim to coupons, dividends, or company earnings. The warehouse owner earns a return only if the copper price rises above carrying cost, or gains value from convenience yield if the holder has a specific industrial need for having the metal on hand.
Result and interpretation
The bond's value reflects expected contractual payments, default risk, and the required discount rate. The equity's value depends on the company's ability to convert copper into profit and then into dividends. The copper's value depends only on physical market conditions, not on any promise to pay. Physical copper and commodity derivatives provide different forms of commodity-price exposure. Futures also introduce maturity, collateral, and rolling considerations. Mining equity can move differently from copper because operating costs, hedging, leverage, and company decisions affect shareholder returns.
Common Exam Traps
Applying a dividend discount model to physical inventory
A commodity generates no contractual or residual cash flow. Discounting an assumed dividend stream to value a commodity produces a meaningless result. Value the commodity through supply, demand, carrying cost, and convenience yield instead.
Treating convenience yield as a cash distribution
Convenience yield is not a payment received by the holder. It is a nonmonetary benefit from guaranteed access to physical inventory. Do not subtract it from price as though it were a coupon or dividend.
Equating a producer's equity value with its commodity price
A mining company's share price reflects operating cost, debt level, management decisions, and hedging strategy in addition to the copper price. These two values do not move together on a one-for-one basis.
Practice Question
A copper wire manufacturer keeps a physical inventory of copper on site to avoid stopping production if a shipment is delayed. An analyst compares this holding to owning a bond or owning shares in a copper mining company. Which feature most distinguishes the manufacturer's copper holding from the bond or the equity shares?
The copper holding provides a contractual coupon payment tied to the copper price.
The copper holding provides a shareholder claim on the mining company's future profits.
The copper holding provides a noncash benefit from guaranteed access to physical inventory.
Correct Answer: C
The manufacturer's copper inventory provides convenience yield, a noncash benefit from avoiding a production interruption. Neither a bond nor equity shares provide this benefit, because both are financial claims valued through contractual or residual cash flows, not through physical access to an input.
Why Other Options Are Wrong
Option A: Copper generates no contractual coupon. A coupon is a bond feature, not a feature of a physical commodity.
Option B: A shareholder claim on profits belongs to equity ownership in the mining company, not to the physical metal itself.

FAQs About Commodity Valuation vs Equities and Bonds
Why does physical commodity valuation differ from equity valuation?
Commodity valuation depends on physical supply, demand, and storage economics. Equity valuation depends on discounted expected dividends or earnings, which require a contractual or residual business claim that a commodity does not have.
Is convenience yield a cash payment?
No. Convenience yield is a noncash benefit of holding physical inventory, such as avoiding a production shutdown. It is not received as a coupon, dividend, or any other cash distribution.
Can leasing a commodity create income?
A separate lending or leasing agreement can generate a contractual payment for an inventory owner. That payment comes from the agreement, rather than an inherent coupon or dividend attached to the physical commodity. Identify the asset and the contract separately when choosing a valuation approach.
