Commodity Agreement
Commodity agreements are international agreements designed to stabilise commodity prices in the interest of producers and consumers. They can include mechanisms to influence market prices by adjusting export quotas and production when market prices reach certain trigger price levels. They sometimes employ buffer stocks which release stocks of commodities onto the market when prices rise to a certain level and build them up when they fall.
