Nasdaq Veles California Water™ Index

水市场交易涉及水的各种所有权权益的出售或租赁。水权赋予所有者从河流、溪流和地下水盆地引水或抽水的权利。水权是最常交易的所有权权益类别。其他常交易的权益包括地下水银行的股份、地表水库储存权和处理过的废水的权益。与其他更常交易的自然资源相比,美国西部水市场的总体规模相对较小,然而,鉴于水供应的相对稀缺,该地区已经出现了新兴但快速增长的水权交易市场。水交易在每个西部州都发生,市场活动常规发生在20多个不同地区。加州,特别是该州南部,是按交易量和价值计算的最大市场。加州每年交易的水的价值和数量几乎是其他州的四倍。其他著名市场位于科罗拉多的前沿地区、亚利桑那州和德克萨斯中部(靠近奥斯汀和圣安东尼奥)。这些市场在地方和区域层面形成,以应对各种市场条件、公共政策,最终是为了满足不断增长和变化的需求。

The overall size of water markets in the western U.S. is relatively small compared to other more commonly traded natural resources, however, given the relative scarcity of water supply, the region has seen the creation of nascent, but rapidly growing markets for the transacting of water rights. Water trading occurs in every western state, with more than 20 distinct regions where market activity routinely occurs.

California, particularly the southern part of the state, is the largest market by volume and value. The value and volume of water traded annually in California is nearly four times that of other states. Other prominent markets are in the Front Range of Colorado, Arizona, and Central Texas (near Austin and San Antonio). These markets have formed at local and regional levels in response to a variety of market conditions, public policy, and ultimately the need to supply water for growing and changing demands.
