What is the interest of calendar swaps for commercials? The settlement price is the monthly average price of daily close if I am right.

 

Less volatility because it's an average of settlements, occasionally across two underlying months.

 

Thanks. It must move close to the futures at the beginning of the month and barely at the end( the settlement is almost known ...), right?

 

Correct.
