Explanation:
Cash flow at maturity:
| Notional | Coupon | |
|---|---|---|
| Tranche 1 | 100 | 0.75 |
| Tranche 2 | 100 | 1.25 |
| Tranche 3 | 100 | 1.50 |
Based on the law of one price, if we can construct a portfolio (using tranches 1 and 3) that has the same cash flow as Tranche 2, then both should have the same price.
Suppose we invest x% in Tranche 1 and (100-x)% in Tranche 3. In order to ensure the same cash flow x, the formula is the following:
x × 0.75 + (1 − x) × 1.5 = 1.25 → x = 33.33%
33.33% invested in Tranche 1 and 66.67% invested in Tranche 3 will cost:
33.33% × USD 97.54 + 66.67% × USD 103.72 = USD 101.66

Q.18 The Treasury Department of a regional bank recently got additional liquidity, amounting to USD 10,000,000. Gayane Gag, head of the treasury department, is interested in a T-Bond that is maturing at the end of September 2017. The tranche is paying a coupon rate of 2.5%. Although the tranche is not actively traded on the market, Gayane manages to collect the following information:
| Maturity | Coupon Rate | Price (per USD 100 face value) | Coupon frequency | |
|---|---|---|---|---|
| Tranche 1 | 30/09/2018 | 1.5% | USD 97.54 | Semiannual |
| Tranche 2 | 30/09/2018 | 2.5% | n/a | Semiannual |
| Tranche 3 | 30/09/2018 | 3% | USD 103.72 | Semiannual |
