A manager of a $40 million dollar fixed-income portfolio with a duration of 4.2 wants to lower the duration to 3. The manager chooses a swap with a net duration of 2.1. What notional principal (NP) should the manager choose for the swap to achieve the target duration?  
  
NP = $40,000,000 × (3 − 4.2) / -2.1NP = $22,857,143  
Since the manager wants to reduce the duration of his portfolio, he should take a receive-floating/pay-fixed position in the swap with that notional principal. Remember that a receive-floating swap has a negative duration, so we enter –2.1 in the equation. |
