# Iron ore: Correlation

Prices it moves with, and why

Source page: https://www.materialinsights.org/commodities/iron_ore/correlation/

Iron ore is shipped mainly from Australia and Brazil to Chinese steel mills, so Chinese steel output and property construction set the price. It trades on Singapore and Dalian futures and on index-linked contracts.

Units: $/dmtu and index, BLS base period. The fit is loose, so treat the function as a rough guide.

 Both prices rebased to 100 at Jan 2006, on a log scale so equal percentage moves look the same size.

 Each dot is one month; paler dots are older (2006), darker dots recent (2026); the ringed dot is the latest month. The dashed line is the fitted price function. Both axes are logarithmic.

 Commodity [St Steel](https://www.materialinsights.org/commodities/steel/)Main use 0.07

Almost all iron ore is smelted into steel, so mill output and margins in China decide demand. The steel index here is for the US, where mills mostly melt scrap, so monthly moves hardly correlate (0.07) and yearly ones correlate at 0.32.

 Energy [Kc Coking coal](https://www.materialinsights.org/energy/coking_coal/)Co-input 0.27

Blast furnaces need iron ore and coke together, so both follow Chinese steel output and restocking. The coking coal series here is a thermal coal proxy, which correlates with iron ore at 0.27 monthly and 0.37 yearly.

 Commodity [Cu Copper](https://www.materialinsights.org/commodities/copper/)Common driver 0.41

Both metals depend on Chinese construction and infrastructure spending, so property slowdowns hit them together. Monthly changes correlate at 0.41 and yearly at 0.69, a common-driver link rather than an input one.

 Energy [Tk Tankers, barges and fuel trucks](https://www.materialinsights.org/energy/e_tankers/)Freight cost 0.01

Iron ore is the largest dry bulk cargo, and freight from Brazil to China is a big part of the delivered cost. The proxy is a US deep-sea freight index that shows no monthly correlation (0.01); a dry bulk freight index would fit better.

 Chemical [H2 Hydrogen](https://www.materialinsights.org/chemicals/hydrogen/)Future reductant −0.06

Green steel plans use hydrogen to reduce high-grade iron ore pellets directly, which would raise the premium for high-grade ore. Today the hydrogen index is a US industrial gas price and shows no link with ore (-0.06 monthly).

How to read these numbers

**Correlation of monthly changes** (the number in the coloured pill) compares how much each price moved, month by month, since 2006 or the first month both series exist. It runs from −1 to +1: near +1 the two usually rise and fall in the same months, near 0 there is no link, and a negative number means they tend to move in opposite directions. Above 0.7 is strong, 0.4 to 0.7 moderate, 0.2 to 0.4 weak.

**12-month changes** compare year-on-year moves, which shows whether two prices share the same cycles even when the month-to-month noise differs.

**Price function** is a straight-line fit of the two prices on logarithmic scales: price ≈ k × (partner price)^β. β is how much this price moves, in per cent, for a 1% move in the partner over the whole period, and R² is the share of the variation the fit explains. Two prices that both drift up with inflation can fit well without any real link, so read it together with the monthly correlation.

**Lead or lag** checks whether the monthly correlation is clearly higher when one price is shifted by 1 to 6 months.

Correlation is not cause. The reasons on each card explain the economic link; the numbers show how strongly it has shown up in prices. Proxy series are US producer price indexes or related prices and can blur the real link.
