Editing Normal backwardation (section)

== Examples ==
Notable examples of backwardation include:

* [[Copper]] circa 1990, apparently arising from [[market manipulation]] by [[Yasuo Hamanaka]] of [[Sumitomo Corporation]] in what has come to be called the "[[Sumitomo copper affair]]".{{Citation needed|date=November 2010}}<!--  Added the newest article where he mentions this, but probably the earliest would be better.  Anyone have time to look? -->
* In 2013, the wholesale commercial gas market entered backwardation during the month of March. The 2-year contract prices fell below the price of 1-year contracts.<ref>{{Cite web | url=http://www.apolloenergy.co.uk/wholesale-gas-market-an-important-update/ | title=Wholesale gas market – an important update| date=2013-03-14}}</ref>
