When a basket is stored, their price stabilization can in turn stabilize the overall price level and prevent inflation. This scenario is on the right. If the market falls within the two limits set by the Agency, no action shall be taken. However, if the market price moves across borders, buffer warehouse operators intervene. Compensatory storage systems are managed by a central authority and aim to stabilise prices and protect producers from sudden changes in supply and demand (often in the case of agriculture). This is done by «Resting in the wind», that is, if there is too much supply, forcing the price down, the buffer storage agency will increase demand by buying stocks. If there is a shortage of offers that drives up the price, the agency will put shares on the market and force the price down.
