The document proposes a virtual global food reserve policy to address food crises. It consists of two parts: 1) a minimum physical grain reserve for humanitarian assistance, and 2) a virtual reserve and intervention mechanism backed by a financial fund. The virtual reserve would intervene in futures markets when prices rise above estimated price bands, executing silent short sales to lower speculative prices without realizing losses. This mechanism aims to stabilize prices through influencing expectations while minimizing market distortions.
