Basis is simply the difference between futures and cash.
Period.
It is NOT a cost.
Graincos do not buy your grain at "whatever under" and sell it for futures price.
Basis is a price (or a component of price, if you prefer).
On wheat in western Canada, you can look at it a number of ways:
1. Convert the futures to CAD, then deduct the CAD cash price.
Basis in CAD.
2. Convert the CAD cash price to US, and deduct from futures (in USD). Basis in USD.
3. Take the Cash price in CAD and deduct futures (in USD).
Basis is neither USD or CAD - it holds the FX conversion.
Each of them is right (so I won't say your 100 under is the "true" basis). I have been stressing that the way the graincos do it (#3) shouldn't be vilified. It works and it in no way hides anything from you. It is a superior way to manage a hedge book.
For what it's worth, I track basis using #2 and #3.
