Convenience Yield

利便性利回り(コンビニエンス・イールド) Forward Curve ✓ Verified Citations Academic Origin
<Definition> Convenience yield refers to the theoretical rate of return (an implicit yield) representing the economic benefit derived from holding physical inventory. This benefit includes practical value arising from having physical supply on hand — protection against supply disruption, continuity of production and sales, and the ability to maintain contractual delivery commitments. The concept traces back to Kaldor's (1939) discussion of the economic benefits of holding physical inventory, and was systematized within the theory of storage by Working (1949) and Brennan (1958).[1][2][3]

<定義>利便性利回り(コンビニエンス・イールド)とは、現物(在庫)を保有することによって得られる経済的便益を表す理論上の収益率(暗黙の利回り)である。ここでいう便益には、供給途絶への備え、生産・販売の継続、契約履行能力の維持など、現物を手元に保有していることから生じる実務上の価値が含まれる。この概念は、現物保有の経済的便益に関するKaldor(1939)の議論を源流とし、Working(1949)およびBrennan(1958)による貯蔵理論の中で体系化された。[1][2][3]

<Mechanism>

Convenience yield and the futures priceStarting from a spot price of $100, the one-year futures price is set by the combined 7% of interest and holding costs minus convenience yield y. With y at 3% the exponent is +4% and the futures price is about $104.1, above spot (contango); with y at 10% the exponent is -3% and it is about $97.0, below spot (backwardation). Figures are hypothetical and for illustration. Price ($) Spot 100 104.1 97.0 Contango (y = 3%) Backwardation (y = 10%) Spot 1-year futures Time to expiry → Interest + holding costs (r + u = 7%) − convenience yield (y) y = 3%: +7% − 3% = +4% y = 10%: +7% − 10% = −3% When y exceeds 7%, the futures price falls below spot
