Assume today is $4$ May $2010$ and you intend to borrow using the $90-$day Bank Accepted Bills $($BAB$)$ on $11$ June $2010.$ You decide to take a position in the BAB futures contract to hedge the interest rate risk that you are likely to face between now and $11$ June $2010.$ What is the nature of the interest rate risk you are likely to face, and how will you use the BAB futures contract to hedge that risk?
