Trading the Rebar-to-Iron-Ore Futures Price Ratio
Summary
The article develops a relative-value framework for Chinese rebar and iron ore futures. Because iron ore is a major steelmaking input, their prices are linked, but the author argues that simple steel-margin formulas can be distorted by coke prices, production differences, and subjective cost assumptions. The proposed alternative is to trade changes in the rebar-to-iron-ore price ratio. The discussion classifies ratio moves by which contract rises or falls more, then outlines conditions for going long or short the ratio, including iron ore’s relative valuation, supply expectations, volatility, and futures-curve discounts.
Historical observations cited in the article suggest that ratio behavior changed around 2015 as deferred iron ore contracts reflected stronger oversupply expectations; it also discusses approximate move durations and candidate ratio zones. These are historical interpretations and period-specific thresholds, not demonstrated universal signals. The article considers hedge ratios, favoring a more conservative rebar-to-iron-ore position mix in some cases, and connects the trade to production, inventory, demand, and policy conditions. It provides no rigorous out-of-sample validation, transaction-cost analysis, or current market assessment, so the framework requires updated data and risk testing.
Key ideas
- The article proposes trading the rebar-to-iron-ore futures ratio instead of relying solely on a steel-margin formula.
- Ratio changes depend on which market rises or falls more, with iron ore described as the more volatile leg.
- Futures-curve discounts and shifting supply expectations are offered as explanations for historical ratio patterns.
- The article discusses different leg ratios as a way to alter exposure and loss variability.
- Its historical thresholds and market interpretations are period-specific and lack out-of-sample validation.
