  • Many commodities follow the Li Keqiang index with lags of four to six quarters
  • Industrials metals such as aluminum and copper show the strongest correlations
  • Crude oil, corn, wheat and soybean oil also have strong correlations
  • The Li Keqiang index is much more positively correlated with movements in commodities than China’s official GDP

Over the past 16 years, China’s “Li Keqiang” Index, has been highly correlated with the prices of many commodities including agricultural and energy products, and industrial metals.  The pandemic period has been no exception.  In fact, between 2005 and 2021, the index has consistently shown a more positive correlation with every major commodity than has China’s official GDP (Figure 1). This may be because it works especially well as a proxy for China’s manufacturing sector.

The Li Keqiang Index includes only three components: rail freight volumes, electricity production, and bank loans.  The index dipped sharply in Q1 2020 amid China’s lockdown, corresponding to a sharp drop in the prices of most commodities.  It then rebounded to show year-on-year economic growth rates of as high as 17% by early 2021.  During this period, commodity prices surged with the prices of many goods rising 100% or more off their 2020 lows.  In recent months China’s growth has slowed sharply to around 5-6% and commodity markets have tended to see more sideways price action. 

Prior to the pandemic, the Li Keqiang Index showed a great deal more variability than China’s official GDP, which spent many years growing at an annualized pace of around 6.5-7.0% per year.  The Li Keqiang index showed much sharper slowdowns in 2009 and in 2014-16 than the official GDP did, while showing much stronger economic growth from 2010-12 and 2017-19 (Figure 2).  With a few exceptions like gold, commodity markets tended to follow what the Li Keqiang index was doing – sometimes with a significant lag of up to one year or more.
