Autopsy of a futures market failure: Japan’s Dojima rice futures in the early 21st century
研究了日本大阪堂岛交易所大米期货在2021年停止交易的原因，发现现货市场碎片化、单一主导企业、政治反对和监管不确定性导致期货无法实现价格发现和套期保值功能，对政策制定者和交易所有警示意义。
• Rice futures trading ceased at Japan’s Osaka Dojima Exchange in 2021. • The Japanese rice market failed to meet the multiple conditions necessary for successful futures trade. • With fragmented spot rice markets, futures trading could not foster price discovery and encourage hedging. • Rice futures trading in Japan provides a cautionary case for policy makers interested in promoting commodity futures trading. Futures markets promise improved price transparency and risk mitigation for staple commodities important to many developing countries, but they can fail even in developed economies with modern financial institutions. We investigate rice futures trading in Japan at the Osaka Dojima Exchange to identify the reasons underlying its failure in 2021. Our analysis reviews the multiple necessary conditions for a successful commodity futures market. We find the Japanese rice market did not meet many of these conditions. The spot market was fragmented with heterogeneous goods and a single dominant firm. Futures trading was unable to facilitate price discovery or effective hedging activity. To the extent it was traded, the Dojima rice futures contract was instead used as a forward contract for making and taking physical delivery. In addition, there was political opposition and regulatory uncertainty around futures trading. Using detailed data on trader positions in the futures market, we show how these factors contributed to diminished interest in futures trading from firms who handle physical commodities. The lessons from the Japanese case are useful for traders, exchanges, and policy makers, especially those in countries where futures markets may face similarly unfavorable economic and political conditions.
