Frequently asked questions

What is basis in commodity trading?

Basis = Local Cash Price − Futures Price for the nearby contract month. A negative basis (cash below futures) is 'weak', positive is 'strong'. Traders quote physical deals as 'basis to March CBOT wheat' meaning cash = March futures + basis on the fixing date.
