Define the balance perimeter #

Write the identities used by the dataset: supply categories, demand categories and the treatment of investment and stocks. Identify whether the report describes the previous year, an estimate of the present year or a forward scenario. A publication’s title year is not necessarily the observation year of every number inside it.

The Silver Institute/Metals Focus survey provides a sector framework; retain its methodology and revisions. Do not combine an early forecast with a later historical estimate as though both were contemporaneous observations. An annual deficit is a measured or estimated flow balance under that framework, not the physical extinction of metal.

Build an industrial demand bridge #

Break a segment into activity × material intensity × technology mix, with explicit treatment of scrap and manufacturing yield. For a photovoltaic study, a capacity installation forecast is not automatically the same as current cell manufacturing and metal use. Choose the point in the chain that the intensity estimate describes.

IEA PVPS material-flow scenarios examine how deployment, substitution and recovery affect future material requirements. Use such work to construct alternatives, not to turn one scenario into certainty. Price changes can accelerate thrifting, but the timing and feasibility depend on technology and investment.

Do not assume silver mines determine all supply response #

A by-product source can respond to the economics and constraints of another metal’s operation. Geological grade, maintenance, treatment availability and investment lead times can matter. A higher silver price does not instantly create the same proportional increase in mine supply.

Recycling depends on accessible material, collection, recovery economics and the location/form of scrap. A price rise may improve incentives while logistical or technical constraints delay response. Specify which elasticities are assumed rather than burying them in a single demand number.

Reconcile a deficit with stocks and prices #

When demand exceeds the defined supply flow, another balance-sheet item or stock movement must complete the accounting under the model. Available above-ground holdings, location and willingness to release them at different prices matter. An observed inventory decline may cover a particular perimeter rather than the entire market.

A deficit can coexist with a falling price if expectations, investor liquidation, currency or financing conditions change. That does not make the balance irrelevant. It means a long-horizon flow model and a near-term price model answer different questions.

Quantify sensitivity and state the missing data #

Build at least an activity/intensity case matrix and a recycling/stock-access stress. Keep units, quality, sector scope and time basis compatible. A small intensity assumption error can exceed the change in a headline activity forecast.

Assign ranges where evidence is weak. Do not calibrate a balance until it produces the desired price opinion. Your output should show which observation could move the conclusion and when that observation becomes available, rather than an unsupported point target.

Hypothetical worked example

A fictional intensity offset

A segment manufactures 1 billion units using 10 grams of silver per unit: 10 billion grams, or 10,000 tonnes. Output rises 20% while intensity falls 15% to 8.5 grams. Metal use becomes 1.2 billion × 8.5 grams = 10.2 billion grams, or 10,200 tonnes—only 2% growth.

A separate fictional balance has supply of 1,000 million ounces and demand of 1,050 million ounces. The 50-million-ounce gap says nothing about the timing of a price move until stock availability, investor behaviour and expectations are specified. Do not add this invented balance to any live survey table.

Common mistakes

Equating installation growth with equal metal-demand growth.
Treating a projected deficit as exhausted physical stocks.
Mixing report vintages to improve a narrative.

Check your understanding

Activity grows 20% and material intensity falls 15%. What happens to metal consumption before other changes?

Make this chapter useful

Can you defend the reasoning?

Before moving on, answer the self-check in your own words and write why each alternative fails. Use the worked example to test that explanation. Then apply it in the module research task; keep the assumptions and the evidence that could change your answer.

Desk assignment

What to submit

Submit a sector activity/intensity matrix, a balance identity and a revision log. Identify the assumption with the greatest effect and the data needed to test it.

Use the research ledger for dated evidence, or the module workbooks for calculations. Separate observations, assumptions and interpretation.
