The US EIA, Crude Supply, Shipping, and the Contango
Our markets, the DJIA, the Nasdaq, and the S&P, as well as many other indicii, depend on the Energy Sector. If the Energy sector has a bad day ... the markets are going to have a bad day.
I recommend visiting the United States Energy Information Administration's (US EIA) website.
You won't find info on ships being used for storage, and there's a lot of other info I feel is critical - yet missing, But, for those of you who don't know crude oil market basic info but want to know how it all works, the US EIA has a 6 chapters primer with over 400 links that's going to explain a lot.
" Oil Market Basics
A primer on oil markets combined with hotlinks to oil price and volume data available on the Internet
