Which commodities will have the biggest drop in prices?

Which commodities will have the biggest drop in prices in the next 12 months and beyond?

I think following commodities will have the biggest drop in prices due to so many facts:

Soybean, Corn, Lead and Nickel

Then following commodities will have the second biggest drop in prices:

Oil and oil related
Wheat
Palm oil

Even prices of natural rubber, beverages such as coffee and tea prices will come down sharply in the next 12 month.

Market will be well supply in the next financial year and beyond. In some commodities almost all the countries through out the world have expanded their production and planting capacities and definitely, there will be over supply situation sooner than later.

As results of lower commodity prices, some commodity currencies will come down sharply. In addition, their all types of assets will come down at the same time in the next 02 years and beyond.

Any other thoughts.

Thanks.
