Reinvestment Planner
What it does
The Reinvestment Planner answers a specific question: "My bond matures next month — which available bond should I reinvest into, and what will my income look like after?"
You select your maturing bond, and the planner compares the reinvestment options available in the current bond database — showing the new annual income, yield, and maturity date for each candidate — so you can make a quick, data-driven decision.
When to use it
- A bond in your portfolio is approaching maturity and you need to redeploy the proceeds.
- You want to see whether staying at the same maturity horizon maintains your income level, or whether you need to extend duration to preserve yield.
- Comparing reinvestment options when the yield curve has shifted since your original purchase.
FXD1/2026/2 matures — reinvesting KES 1M principal
Your FXD1/2026/2 (16.00% coupon) matures in February 2026 and returns your KES 1,000,000 principal. You want to compare reinvestment options. The planner lists all currently available bonds and projects your annual income from each.
Example output
| Bond | Coupon | Maturity | Current Yield | Annual Income (KES 1M) | Change vs. current |
|---|---|---|---|---|---|
| FXD1/2028/5 | 14.39% | Mar 2028 | 15.90% | KES 143,900 | −KES 16,100 |
| FXD2/2030/10 | 13.49% | Jun 2030 | 16.10% | KES 134,900 | −KES 25,100 |
| IFB1/2031/12 | 12.50% | Dec 2031 | 14.30% | KES 125,000 | −KES 35,000 gross +KES 2,000 after tax (WHT exempt) |
The table shows that all options pay less than the maturing 16% bond — yields have fallen at the short end. However, the IFB1/2031/12 is competitive after tax because its coupons are WHT-exempt, effectively adding back 15% on each coupon payment.
Limitations
- Only shows bonds currently in the database. Bonds not yet issued or not yet scraped will not appear.
- Income projection uses the coupon rate, not the market yield — the actual amount received depends on the price you pay at auction or on the secondary market.
- Does not account for partial reinvestment or splitting proceeds across multiple bonds.
