That is the reason why in these countries water demand policies have been recently developed, in order to rationalize its consumption. Among these instruments, water markets are perceived to be the most promising one in this way, allowing a more efficient allocation of the resource. Spain it is included into these countries with water supply problems. Thus, the Spanish Water Act Reform achieved in 1999 includes the possibility to develop spot markets for water (use rights leasing). The success of this reform will be subject to the specific characteristics of the economy of the water in this country, which will condition the correct operation of the water markets. This paper analyses the Spanish case, pointing out the circumstances that will hinder the correct operation of this economic instrument.
