Prices of the Zinc Element in the World
Before delving into the prices of zinc elements in the world, we need to understand the factors that are affecting the prices of zinc elements.
First of all, zinc is not an investment tool that is used by investors. We can not seek investor behaviors to assess the prices of the zinc element. Investor behaviors are very apparent for precious metals such as gold and maybe silver. But investing and investments are not the main factors that affect the zinc prices in the world.
The biggest producer of zinc elements in the world is China. So, the political and economical situation in China will affect the zinc prices in the world.
Also if we look at the biggest importers of Zinc in the world, the biggest Zinc importer is the US. Also, the EU countries are in the first place in importing zinc elements. So, the economical and political relations between China and the US will affect the zinc prices in the world. Also, the situation of the commercial logistics between the US and China is a very important factor that affects the zinc prices in the world. We can assess the zinc prices according to these facts.
tradingeconomics.com provides very good data that ranges nearly 60 years of zinc prices in the world. If we take a look at the 60 years of prices, there is a great increment in zinc prices. But this increment is because of the inflation rate that is applied to the US dollar. There are some imminent peaks and downs in the zinc price graph and the most important increment is around 2008. 2008 is a very important year the global economic crisis happened which is centered in the US. Because of this economic crisis, the exportation and importation of the zinc element are affected heavily, and you can see the sharp peak in the zinc price. The zinc price has seen the highest level at that peak.
Also, you can see another peak in zinc prices around 2016 when the trade war between the US and China started. Also, the covid-19 outbreak is another important factor in the prices of zinc.
As you understand that zinc prices are affected by the economical situations of the biggest countries and the politics between these countries. Price estimations of zinc elements in the world can be made according to this extent.
