| Summary: | We examine the market quality of China's steel rebar futures, along with three other important industrial metal futures. Steel rebar futures are the most active metal futures contracts in China. Our analyses show that while steel rebar and copper futures are comparable in terms of informational efficiency, they are more informationally efficient than iron ore and aluminum futures, with low bid–ask spread, volatility persistence, pricing error variance, and probability of informed trading. We find a bidirectional connection between iron ore and steel rebar futures. Furthermore, we show that these metal futures are weakly related to the Chinese stock market. © 2019 Wiley Periodicals, Inc.
