“Spot” describes the delivery horizon. It does not promise that goods move, title transfers and money arrives at the same instant. Prompt delivery must be interpreted under the market's conventions and the purchase agreement; payment follows the agreed terms. There is no single commodity-wide settlement delay implied by the word.
Read the price before using it
A number labelled “wheat” or “oil” is an incomplete price observation. Keep the fields that tell you what the number measures:
| Field | What to establish |
|---|---|
| Product and grade | The physical form and quality covered by the quote |
| Location and delivery basis | Where the goods are available and which transport or handling services the price includes |
| Observation time | When the price was quoted, traded or assessed, including the time zone where relevant |
| Delivery window | The prompt delivery period represented by the observation |
| Currency and quantity unit | For example, USD per metric tonne; also any quantity conditions attached to an offer |
| Price type | A buyer's bid, seller's offer, completed trade or published assessment/average |
The price type affects what can be done with the observation. A buyer cannot assume it can purchase at a bid, and a reported average is not automatically an executable offer for its required quantity.
From a spot quote to a purchase bill
The commodity line of the purchase bill is
The physical quantity cancels the quote's denominator. USD 200 is the price per unit; USD 2,000 is the amount for this lot, before taxes, delivery and storage charges. Neither number specifies when the invoice must be paid.
A different warehouse's quote is not automatically a cheaper substitute: moving the goods to the required destination may change the comparison. Nor does a higher quote for a different grade establish that the original lot has gained value. A price-change series should hold the physical basis and observation method consistent, or identify the adjustments being made.
