China is definitively at risk I believe as China never cleaned up its banking sector and/or shadow banking system. The same can be said of Europe and the US or Japan, but China is the ultimate buyer of all commodities and can have a more devastating impact if a shock would happen.

Therefore going into 2019-2020, I will remain very cautious on bullish commodity bets besides precious metals.
