We would like you to take a look at an example of futures curves for oil for different moments in history. The WTI (West Texas Intermediate) chart shows oil price over the recent decades, while here you can depict futures WTI crude oil futures prices for selected dates.

How informative, in your opinion are the futures curves about the the future oil spot prices and why?
