Example Bond Switch
Scenario: Switch from low-coupon bond to higher-yielding bond
| Position | ISIN | Coupon | Maturity | Price | Duration |
|---|---|---|---|---|---|
| SELL | KE0001234 | 12.50% | 2029 | 98.45 | 4.2 yrs |
| BUY | KE0005678 | 16.75% | 2031 | 102.30 | 5.8 yrs |
Annual Income Change
+KES 425,000
16.75% - 12.50% = +4.25% on 10M face
Duration Change
+1.6 years
Increased interest rate sensitivity
Net Cash Impact
-KES 380,000
Additional outlay required
Realized Gain
-KES 155,000
Loss on sale (purchased at par)
When to Switch
Bond switches make sense when: (1) You can significantly increase income without excessive duration risk, (2) You want to reposition ahead of rate changes, (3) You need to harvest tax losses, (4) Relative value has shifted (one bond cheap vs another), (5) Liquidity profiles have changed.
Risks to Consider
Switching risks include: (1) Execution risk - prices move before you complete both legs, (2) Realized loss impact on P&L, (3) Increased duration if rates rise, (4) Liquidity risk in replacement bond, (5) Transaction costs eroding benefits. Always stress test the new position under adverse scenarios.
