B.Purpose of Swaps 1.Hedge future [adverse] movements of interest rates → payments 2.Immunize portfolios of interest-sensitive assets

Price = $ 543, Suppose further that we can borrow money at 5 % per annum for 3 months with the loan collateralized by the Zc-bond. 3.We borrow $ 543, and repay $ 543, * = $ 549, or a cost of $ 6, We sell (= open a short position) a futures contract to deliver the Zc- bond, 3 months hence, priced to yield 6.00%: Price = $ 551, for a expected profit of $ 8, We have created an arbitrage portfolio in which we have no money invested and have earned a profit of $8, $6, = $1, with no risk. 6.In this example, the 6 % is the implied repo rate or the IRR on Zc- bond.
