In 2003 and 2004, an insurance product that protects against market risks of agricultural commodities was offered in Spain. It consists on a revenue insurance product which has been launched as a pilot program for mid-season and late potato in five Spanish provinces (Álava, Burgos, La Rioja, León and Valladolid). The objective of this article is to describe the characteristics of this insurance product and to perform a preliminary evaluation of the seasons it was marketed. We start from a conceptual approach to the market risk management instruments, that constitute the context for the current program. Later, we explain the price model used to define market reference prices and the premia, checking the quality of the statistical price model against the potato farm-gate prices. Finally, the article ends with a preliminary valuation/ assessment of this first pilot experience in Spain, stressing those aspects which are liable/prone to be improved and reckoning the possible extensions of this insurance line to other potato varieties, provinces and also to other agricultural commodities.
