Cost of Carry Components

  • Benefits (γ): Dividends, coupons, convenience yield - reduces forward price
  • Costs (θ): Storage, insurance, spoilage - increases forward price
  • Net Carry: (S₀ - γ + θ) is the adjusted spot basis
  • Compounding: (1+r)^T accounts for financing costs

Formula Breakdown

F₀(T) = (S₀ - γ + θ) × (1 + r)T

Cost of Carry Interpretation

Scenario Effect on Forward Typical Assets
High Benefits (γ > θ) Lower Forward Dividend stocks, bonds
High Costs (θ > γ) Higher Forward Commodities, precious metals
No Carry (γ = θ = 0) Basic F = S(1+r)^T Non-dividend stocks
Convenience Yield Backwardation Oil, agricultural goods

Understanding the Cost of Carry Model

What is Cost of Carry?

Cost of carry is the total cost of holding a physical asset or financial position over time. It includes all costs and benefits associated with ownership until the forward contract matures. The full cost of carry model adjusts the basic forward pricing formula to account for these factors.

Full Cost of Carry Formula
F₀(T) = (S₀ - γ + θ) × (1 + r)T

Cost of Carry Components

Benefits (γ) - Reduces Forward

Income from holding: Dividends (stocks), Coupons (bonds), Convenience Yield (commodities). Spot holder receives these while forward holder does not.

Costs (θ) - Increases Forward

Expenses of holding: Storage (warehousing), Insurance (protection), Spoilage (perishables). Spot holder pays these, forward holder avoids them.

Present Value Adjustment: Benefits and costs in the formula are expressed as present values. If you know future cash flows, discount them: PV = FV / (1+r)t.

Arbitrage Relationship

The cost of carry model ensures no-arbitrage pricing. If the forward price differs from (S₀ - γ + θ)(1+r)T, traders can profit through:

  • Cash-and-Carry: Buy spot, sell forward if forward is too high
  • Reverse Cash-and-Carry: Sell spot, buy forward if forward is too low
Note: When γ = 0 and θ = 0, this reduces to the basic formula F = S(1+r)T. Use the full model when dividends, storage costs, or convenience yield are significant.

Frequently Asked Questions

γ (gamma) represents benefits or income from holding the asset - things that make owning the spot position valuable. θ (theta) represents costs of holding - expenses incurred. Benefits reduce forward price; costs increase it. Net carry = θ - γ.

Present values ensure all cash flows are measured at the same point in time (today). A $5 dividend paid in 6 months isn't worth $5 today - it's worth less. Using PV makes the formula mathematically consistent and reflects true economic value.

Convenience yield is the non-monetary benefit of holding physical inventory. For commodities, having physical stock provides security of supply, ability to meet unexpected demand, and operational flexibility. It's included in γ and can cause backwardation.

For each expected dividend D paid at time t: PV = D / (1+r)^t. Sum all dividend PVs for the contract period. Example: $2 dividend in 6 months at 5% rate: PV = $2 / (1.05)^0.5 = $1.95. Enter this sum as γ.

When γ = 0 and θ = 0, this reduces to the basic formula F = S(1+r)^T. Use the full model when: the asset pays dividends/coupons, storage costs are significant, or there's material convenience yield. For simple assets with no income or costs, basic pricing suffices.

Forward price can be less than spot (backwardation) when benefits exceed costs plus financing. High dividend yield stocks, bonds with large coupons, or commodities with strong convenience yield can all create backwardation. It's also possible with negative interest rates.
