bufferstock

Buffer stock is a stockpile of a commodity held by a government or international institution with the intent to stabilize prices and ensure reliable supply over time. The core idea is to buy and store the commodity when prices are low or production is abundant, and to release stock when prices rise or supply tightens, thereby dampening fluctuations and protecting producers and consumers.

Buffer stock schemes may use price bands or target prices, trigger points for accession or release, and rules on storage, financing, and disposal. They rely on storage capacity, efficient inventory management, and predictable procurement and release schedules. They can be financed through budgets or loans, and may be integrated with broader stabilization policies.

Historically, many countries have used buffer stocks for staple agricultural products such as grains, sugar, or rice, and some coal or oil programs exist in strategic contexts. The European Union and its member states operated intervention stocks for cereals and other products under common agricultural policy instruments. National programs in various eras purchased surpluses to support prices and later released them during shortages.

Buffer stock schemes face criticism for cost and inefficiency, potential market distortion, and incentives for overproduction or stockpiling, as well as storage losses and spoilage. Their success depends on accurate forecasting, storage discipline, and credible commitment; mismanagement can exacerbate price volatility instead of smoothing it.
