Copper Ore Index: addressing copper price volatility with predictive signals
In July 2020 Copper prices reached to a two year high following a rally that started in March of the year. This represents an increase of almost 40% and makes copper one of the most volatile commodities since the beginning of the year.
With demand driven mainly by China, it is no surprise to see volatility pick up on the back of the first signs of industrial recovery following the first wave of COVID19 in the country. The Shipfix Copper Ore Index tracks cargo order sentiment for the volume of copper ore transported at sea since 2015. Interestingly, the Index shows a predictive correlation to copper price up until March 2020, but afterwards, we observe a decorrelation on the back of the price rally described above.
We see 2 potential factors that could explain this trend:
- Speculation vs. real demand: Copper prices are becoming increasingly subject to speculative pressure with traders betting on an important demand for copper from China in the coming month. Based on Shipfix data, the level of copper ore export does not corroborate the assumption of an increase in the real demand for the commodity and prices should soon see a correction.
- Production output restrictions: Demand for copper has increased out of China but the production and export of copper ore out of South America cannot follow the volumes demanded, partly because of the impact of COVID19 on the broader mining industry. This could explain why copper prices are taking off whilst the Shipfix Copper index remains stable. in this case too, we expect to see a correction in prices shortly after the Shipfix copper index picks up again. The timing for this correction is obviously still uncertain at the time of this post, but our Shipfix Copper index should provide a valuable predictive trading signal in this context.
