Imagine lending money to someone who gives you a written promise showing how much they borrowed, when they will pay you interest, and the date they will return your original money. A Treasury bond is the Government version of that promise. It has more rules and an electronic ownership record, but the basic idea is still lending.
First definition
When the Government of Rwanda needs money for public financing, it can issue Treasury bonds. The Government is the issuer: it creates the promise and owes the payments. You are the investor: you provide the money and receive the promised cash flows. You are lending to the Government, not buying a piece of it.
The bond identifies how much principal exists, how interest is calculated, when interest is scheduled to be paid, and when principal is scheduled to be returned. Rwanda Treasury bonds commonly pay interest twice per year, but each bond series has its own exact dates. A buyer must read the prospectus or confirmation for that particular series rather than assuming that every bond pays in the same months.
Treasury bonds are often described as lower-credit-risk investments because payment is backed by the Government. Lower credit risk does not make every purchase price good and does not make the account value permanently stable. If the investor sells before maturity, the selling price can be above or below the original purchase price. Inflation can also reduce what future Rwandan francs can buy.
A familiar comparison is a brand-new high-end smartphone. The manufacturer releases one model with fixed specifications, but later owners may resell that same phone for different prices. Someone who urgently needs cash might sell cheaply; strong demand might push another resale price higher. A bond behaves similarly on the secondary market: its face value, coupon, and maturity stay attached to the bond, while the price buyers and sellers agree to can move.
One slow example
Imagine a new Treasury bond with RWF 100,000 of face value, a 12% annual coupon rate, two coupon payments per year, and a five-year maturity. For this first example, assume it is bought at its original issue for exactly RWF 100,000 and ignore tax and fees temporarily. Removing those extra details lets us see the basic promise clearly.
The annual interest calculation is RWF 100,000 multiplied by 12%, which equals RWF 12,000 per year. Because payment happens twice per year, each scheduled coupon is half of RWF 12,000, or RWF 6,000. The investor does not normally receive a little interest every day in the bank account. Interest accumulates economically, but cash arrives on the scheduled coupon dates.
If the investor holds the bond for all five years and the Government pays as agreed, the investor receives ten coupon payments of RWF 6,000. Total gross coupon cash is therefore RWF 60,000. On the maturity date, the investor also receives the RWF 100,000 principal. The principal repayment is not an extra RWF 100,000 profit; it is the original amount lent being returned.

A Government bond is a standardized loan certificate, not a savings account that accepts any balance. BNR auction notices commonly structure non-competitive amounts in multiples of RWF 100,000. You choose how many face-value blocks you want.
The market price of a block can move, just as a used smartphone can resell above or below its launch price. A block priced at 97 costs RWF 97,000 clean, but it remains a RWF 100,000 face-value block in the securities record.
1 block = RWF 100,000 face value
5 blocks = RWF 500,000 face value
At price 97, 5 blocks cost RWF 485,000 clean
Words you will see repeatedly
Principal is the amount borrowed and expected to be repaid at maturity. Face value or par value is the principal amount printed in the bond records and used to calculate coupon cash. In everyday discussion, these terms often point to the same contractual amount.
Interestis the compensation paid for using someone else's money. A coupon is one scheduled interest payment. The coupon rate is the annual percentage applied to face value to determine coupon cash. A 12% coupon rate on RWF 100,000 face value means RWF 12,000 gross interest per full year, not necessarily a 12% return on whatever market price a later buyer pays.
Maturity is the contractual end date when principal is due. Tenordescribes the bond's length, often measured from original issuance to maturity. Remaining maturity describes how much time is left today. A bond originally issued with a 20-year tenor may have only 12 years remaining when you discover it.
Price is what a buyer must pay to acquire the bond. Price and face value can be different after issuance. Yield is a way of expressing the return created by the cash flows relative to the price paid. The coupon rate belongs to the bond; yield changes when the market price or remaining time changes.
Where a purchase happens
The primary market is where newly issued or reopened Government debt is offered. The National Bank of Rwanda acts as fiscal agent in the issuance process. Investors submit orders or bids through the permitted channels, often with assistance from an intermediary such as BK Capital. Money raised in the primary market goes toward the Government financing operation.
The secondary market is where an existing investor sells a bond to another investor after issuance. The Government is not creating a new bond in that trade. The buyer pays the seller through the market's trading and settlement process. Because buyers and sellers negotiate under current market conditions, an existing bond can trade at 97, 100, 107, or another price.
A broker helps communicate orders, locate available bonds, execute trades, and provide a contract note or confirmation. The Central Securities Depository, commonly shortened to CSD, maintains electronic ownership and supports settlement. You do not normally receive a paper certificate that must be hidden at home; ownership is recorded electronically.
Yes. Think of it like a high-end smartphone that originally came with a fixed specification. A person who urgently needs cash may resell that same phone for less, but the phone does not lose its original storage capacity. Here, the previous investor accepts RWF 97,000 clean for a bond block registered with RWF 100,000 face value.
After settlement, the electronic ownership record moves to your CSD account. Coupon cash and maturity principal follow the RWF 100,000 face value, not the RWF 97,000 bargain price. Your final debit can still include accrued interest and fees.
Clean price: RWF 97,000
Face value owned: RWF 100,000
12% annual gross coupon: RWF 12,000
Principal due at maturity: RWF 100,000
Level 1 · Learn the numbers
Level 0 used a new bond bought for exactly its face value. Real secondary-market purchases are less tidy. The bond keeps its original coupon and maturity date, but its price moves. This level introduces one distinction at a time: face value versus price, coupon rate versus yield, clean price versus total settlement cash, and gross coupon versus after-tax coupon.
Level 1.1 · Price
Face value, also called par value, is the number written on the bond's official record. It is the amount used to calculate coupon cash and the principal expected back at maturity. If you own RWF 1,000,000 face value with a 12% coupon, the gross annual coupon is RWF 120,000, even if you bought that position for less or more than RWF 1,000,000.
Bond prices are commonly expressed as a percentage of par. When an RSE or broker quote is identified as a clean price, 100 means RWF 100 of principal costs RWF 100 before accrued interest and transaction charges. A clean price of 97 is a discount: RWF 1,000,000 face value has a clean market cost of RWF 970,000. A clean price of 107 is a premium: the same face value has a clean market cost of RWF 1,070,000. The coupon amount remains tied to RWF 1,000,000 face value, not to the market cash paid.
At maturity, the issuer pays face value, not whatever price you happened to pay another investor. Buy below 100 and you can receive more principal than your clean purchase price. Buy above 100 and part of your purchase price disappears when principal returns to 100. This movement back toward face value is called pull to par.
Level 1.2 · Return
The coupon rate is the interest percentage printed on the bond. It determines coupon cash by multiplying that percentage by face value. With semiannual payments, a 13.5% bond with RWF 1,000,000 face value pays RWF 67,500 gross every six months. The rate does not adjust merely because the bond later trades above or below 100.
Yield to maturity is the fairer comparison number. It asks what annualized return the whole deal represents when you include today's price, every remaining coupon, and the principal paid at maturity. A high-coupon bond bought at an expensive premium can therefore have a lower YTM than a lower-coupon bond bought cheaply.
Quoted YTM is not a promise that the investor will realize exactly that annual compound return. It normally assumes the bond is held to maturity, every contractual payment occurs on time, and interim coupons can be reinvested at a rate consistent with the calculated yield. Selling early replaces the known maturity payment with an unknown sale price. Reinvesting coupons at lower rates reduces realized compound return even when the issuer pays every coupon exactly as scheduled.
Level 1.3 · Settlement
Accrued interest sounds technical, but the household version is simple. Imagine you move into a rented house on the 15th of the month. At month-end, the electricity bill covers all 30 days. The previous tenant used electricity for the first half of the month, so you should not keep the benefit of that whole bill calculation for yourself. You settle up for the days they were there.
Bonds have the same idea. Coupon interest builds up day by day, but the cash is paid only on scheduled coupon dates. If you buy from a seller halfway through a six-month coupon period, the seller has already earned roughly half of that coupon period. You usually pay them that earned portion on settlement day. Later, when the full coupon arrives in your account, part of it is really reimbursing money you already advanced to the seller.
The clean price is the simple market quote before that interest adjustment. The dirty price is the fuller settlement price after accrued interest is added. Your final cash debit can also include broker commission and other charges. So a clean quote of 101.50 is useful, but it is not automatically the exact amount leaving your bank account.
The exact accrued-interest calculation depends on the prospectus day-count convention, coupon-period dates, and settlement date. A simplified actual-days illustration helps explain the economics: assume RWF 1,000,000 face, a 12% annual coupon, a RWF 60,000 gross semiannual coupon, and 90 elapsed days in a 182-day coupon period. Approximate accrued interest is RWF 60,000 x 90 / 182, or RWF 29,670. If the clean price is 101.50, clean consideration is RWF 1,015,000 and approximate dirty consideration is RWF 1,044,670 before fees.
No. The coupon may arrive soon, but the seller did not give away the interest they earned during the current six-month cycle. On settlement day, you normally compensate the seller for the days they already held the bond. When the full coupon later lands in your account, part of it is simply the system returning cash you advanced at purchase.
Semiannual coupon: RWF 60,000
Seller held roughly half the period
Accrued interest paid to seller: about RWF 30,000
Next coupon received by you: RWF 60,000 gross
The first coupon can feel exciting, but it is not pure profit if you paid accrued interest upfront.
Level 1.4 · Tax
Tax is removed before coupon cash reaches your account. Rwanda's Law No. 027/2022 provides a reduced 5% withholding treatment for interest from Treasury bonds with a maturity of at least three years. That is why this planner normally shows 5% rather than the broader 15% withholding rate mentioned for other covered payments.
For a qualifying Rwanda Treasury bond modeled at a 5% withholding rate, a 12% gross coupon becomes an 11.4% annual coupon cash rate after withholding: 12% x 95%. On RWF 1,000,000 face value, RWF 120,000 gross annual coupon becomes RWF 114,000 net, normally split according to the security's payment schedule. Tax reduces coupon cash; it does not change the bond's contractual coupon printed in the prospectus.
Do not guess the tax from the countdown shown in a market table. Confirm the bond's classification, current law, and the broker or paying agent's treatment. Personal residence, taxpayer status, and later legal changes can affect the answer.
Rwanda's income-tax law provides a reduced 5% withholding treatment for interest from Treasury bonds with a maturity of at least three years. In everyday terms, the tax is taken out of the interest payment before the net coupon reaches you. The bond still has the same gross coupon rate; your cash account receives the amount after withholding.
Raw semiannual interest: RWF 60,000
Withholding tax at 5%: RWF 3,000
Net cash received: RWF 57,000
Always confirm the current tax treatment from the prospectus, RRA rules, and the broker confirmation, especially if your taxpayer status is unusual.
Level 2 · Avoid bad deals
You now know that coupon rate and return are not the same number. This level combines price, time, tax, and maturity in worked examples. Read it slowly: each example begins with the attractive headline, identifies the hidden cost, and then explains how that cost changes the result.
Level 2.1 · Worked scenario
Consider RWF 1,000,000 face value of a Treasury bond paying a 13.5% annual coupon in two semiannual installments. The annual gross coupon is RWF 135,000, and each gross payment is RWF 67,500. At 5% withholding, annual coupon cash falls to RWF 128,250 and each net semiannual payment is RWF 64,125. Those figures look attractive when viewed without the purchase price.
Now assume the bond has approximately 3.2 years remaining and trades at a clean price of 107. The investor pays RWF 1,070,000 clean for RWF 1,000,000 face value, before accrued interest and fees. At maturity, the issuer repays RWF 1,000,000, not RWF 1,070,000. The RWF 70,000 premium is gradually consumed through pull to par and becomes an explicit capital loss at redemption. The high coupons must first compensate for that loss before they produce excess return.
Under a simplified seven-period semiannual model, excluding accrued interest and fees, the premium bond's approximate gross YTM is 11.03% and its approximate after-tax yield is 10.39%. A par-priced 11.5% bond with the same simplified remaining term produces an 11.5% gross yield and approximately 10.93% after coupon withholding. The supposedly more generous 13.5% coupon therefore delivers the lower modeled return because the buyer overpays for the cash-flow stream and loses the premium at maturity.
Absolutely not. The coupon is the attractive number printed on the bond, but the purchase price decides how expensive those coupons are for you. If a 13.5% bond trades at 107, one RWF 1,000,000 face-value position costs RWF 1,070,000 clean. At maturity, the issuer returns RWF 1,000,000, so the RWF 70,000 premium disappears through the pull back to par.
The premium trap
Clean purchase price: RWF 1,070,000
Principal returned at maturity: RWF 1,000,000
Premium lost at maturity: RWF 70,000
Compare listings by Yield to Maturity, not coupon alone. YTM combines the price you pay, every remaining coupon, and the principal returned at maturity.
Level 2.2 · Time risk
A bond can offer an excellent current YTM and still be a poor fit for a long compounding objective. A security with only 3.2 years remaining returns principal relatively soon. The investor then has to find a new home for that principal. If market yields have fallen, the attractive rate cannot be extended merely because the original bond once paid 13%. This uncertainty is reinvestment risk.
Assume RWF 10,000,000 face value of a par-priced 13% bond with 3.2 years remaining. At 5% coupon withholding, its annual net coupon rate is 12.35%, producing RWF 1,235,000 of net coupon cash per full year while it remains outstanding. Compare it with a par-priced 11.8% bond that can maintain a 15-year exposure. The longer bond's annual net coupon rate is 11.21%, producing RWF 1,121,000. The short bond initially pays RWF 114,000 more per year, but its rate disappears when principal returns.
Suppose, purely as a stress scenario, that reinvestment opportunities after year 3.2 offer only 8% gross, or 7.6% after the same assumed withholding. A rough time-weighted rate over a 15-year objective becomes approximately 8.61% for the strategy that earns 12.35% for 3.2 years and 7.6% for the remaining 11.8 years. The 15-year 11.8% bond preserves an 11.21% net coupon rate over the assumed horizon. This simple comparison omits changing prices and detailed coupon reinvestment, but it shows why a temporarily higher rate can lose to a durable rate lock.
Imagine finding a wonderful 13% bond that matures in only two years. You enjoy that rate for 24 months, and then the Government returns your principal. Now you must find a new place for the money. If market rates have fallen to 8%, the high-rate part of your plan is over.
A slightly lower 11.8% bond with 15 or 20 years remaining may be more useful for a long-term income plan because the rate stays attached to the principal for much longer. That does not make long bonds universally better: their market prices can move more, and they are unsuitable if you need the money soon.
The hidden question
Do not ask only, “What rate do I get today?” Also ask, “How soon will I be forced to find another investment?”
This is the clearer version of the question because it separates four things that are easy to mix together: the printed 12% coupon, the 5% tax on coupon cash, the fact that coupons arrive only twice per year, and the rule that new bond purchases must be made in RWF 100,000 face-value chunks.
After 5% withholding, the net annual coupon rate is 11.4%. With two payments per year, each six-month payment is 5.7% of the bond face value. Your first RWF 1,000,000 position therefore pays RWF 57,000 net every six months.
Paper theory: fractional semiannual reinvestment
But cash is paid only on coupon dates
After 12 payments: about RWF 1,944,912
After 13 payments: about RWF 2,055,771
The equation's decimal answer is approximately 6.25 years, but you cannot reinvest half of a coupon period before the coupon is paid. On an actual semiannual payment calendar, perfect fractional reinvestment first passes RWF 2,000,000 at payment 13, around 6.5 years.
Now apply the RWF 100,000 purchase rule. At month six, the RWF 57,000 coupon waits as cash. At month twelve, another RWF 57,000 raises cash to RWF 114,000, allowing one RWF 100,000 bond purchase and leaving RWF 14,000 idle. The same process repeats, but the coupon grows as more RWF 100,000 blocks are added.
Simplified RWF 100,000-lot result
Month 12: RWF 1,100,000 bonds + RWF 14,000 cash
Month 36: RWF 1,300,000 bonds + RWF 81,900 cash
Month 60: RWF 1,700,000 bonds + RWF 12,500 cash
Month 72: RWF 1,900,000 bonds + RWF 12,000 cash
Month 78: RWF 2,000,000 bonds + RWF 20,300 cash
Under these simplified assumptions, the unassisted portfolio also reaches RWF 2,000,000 of bond face value at month 78, which is 6.5 years. Cash drag is still real: perfect fractional reinvestment would be worth about RWF 2,055,771 at that point, while the chunked strategy is about RWF 2,020,300. The minimum-unit rule costs roughly RWF 35,471 of modeled value by that date, but it does not push this particular first doubling into year seven.
Be careful when adding personal top-ups
Adding your own cash to complete each RWF 100,000 block is a useful strategy because it keeps coupons invested. It can make the account balance reach RWF 2,000,000 earlier. However, part of that second million came from your new contributions. That is not the same as the original RWF 1,000,000 doubling from investment returns alone.
Pooling coupons from several bonds, using income from other investments, or staggering coupon dates can improve the percentage of cash that stays invested and reduce the average waiting time. As the portfolio becomes larger, a leftover below RWF 100,000 becomes a smaller percentage of total wealth, so performance moves closer to the theoretical line. A practical planning estimate is therefore approximately 6.5 years without extra contributions, assuming 12% gross coupon, 5% withholding, stable reinvestment at similar rates, immediate RWF 100,000 purchases when cash permits, and no fees or price premiums.
Level 2.3 · Suitability
YTM is a return calculation, not a complete suitability test. A high YTM may be compensation for poor liquidity, a stale quote, unusual settlement terms, credit uncertainty outside sovereign debt, or a maturity date that conflicts with the investor's cash needs. A screen that ranks yield correctly can still encourage a bad decision if the investor ignores the conditions under which that yield is realizable.
A displayed closing price may represent a small historical trade rather than a currently executable offer. An investor should distinguish the last traded price, the broker's current ask, and the final all-in settlement amount. A model using 97.00 can overstate return if the available seller requires 100.50, or if accrued interest and fees are omitted. Likewise, a published RSE YTM can become stale when no new trade resets the market price.
The final discipline is matching the bond to your real-life need for cash. Money reserved for school fees in four years should not be placed reflexively into a 20-year bond merely because its strategy score is higher. Selling before maturity exposes the investor to the market price then available. Government payment reliability reduces credit risk, but it does not eliminate interest-rate risk, inflation risk, liquidity risk, execution risk, or the personal risk of needing cash at an inconvenient time.
Level 3 · Execute the deal
You do not need to operate the market's professional systems yourself. Your job is to identify the bond, decide the face-value amount you want, understand the likely price and risks, and give clear instructions to a licensed intermediary. The broker or authorized bank channel handles the market and CSD workflow on your behalf.
Level 3.1 · Your buying path
Start by opening or confirming your investment and CSD account details with a licensed intermediary. CMA's public licensee list includes securities brokers and investment banks such as BK Capital. BNR auction notices explain that authorized bank treasurers and brokers use the CSD platform to submit bids for their clients.
For a primary auction or reopening, ask for the official notice and prospectus. Decide how much face value you want, whether your instruction is competitive or non-competitive where applicable, and the deadline for making funds available. For a secondary-market purchase, ask for a current executable offer, the face value available, accrued interest, fees, settlement date, and total cash required.
Do not fund a trade from a website screenshot alone. The RSE closing price is useful market information, but the broker must confirm whether a seller is currently available and the final all-in settlement amount. Keep the order email, prospectus, contract note, payment proof, and CSD record together.
As an individual, you normally give the order through an authorized market intermediary or bank channel rather than logging directly into the professional CSD bidding interface. BNR auction notices state that authorized commercial-bank treasurers and brokers submit CSD bids for their clients.
BK Capital appears on CMA's licensee list as an investment bank. Other licensed intermediaries also exist, so verify the current CMA licensee list before sending money or identity documents. The intermediary can help open or reference your CSD account, clarify the order type, confirm settlement funding, and provide the trade confirmation.
Protect the order
Use verified contact details from the institution or CMA licensee list. Do not send funds to an account supplied only through an unverified message.
Send a clear instruction that identifies you, your CSD account, the exact security, the order type, and the desired face value. Ask the trading desk to confirm the price or auction terms, fees, accrued interest, settlement amount, deadline, funding method, and documents before execution.
Sample order email
Subject: Fixed Income Order - Primary Auction [or Secondary Market] Dear BK Capital Trading Desk, Please execute the following fixed-income order on my behalf: Investor Name: Oreste MUHIRWA GABO CSD Account Number: [Your CSD Account ID] Bond Security Ticker: FXD 1/2026/10YRS Order Type: Primary Re-opening Auction (Non-Competitive Bid) Face Value Target Amount: RWF 2,000,000 Please confirm the required settlement amount, funding instructions, fees, documents, order deadline, and whether any additional authorization is required before execution. Best regards, Oreste MUHIRWA GABO
This is a communication template, not proof that an order has been accepted. Replace every placeholder, verify the ticker against the current official notice, and wait for BK Capital to confirm the instructions and settlement amount.
Level 3.2 · Secondary market
Start with the RSE Fixed Income Board to identify the bond code, issue date, maturity date, coupon rate, and published YTM. Then cross-check the RSE Bond Market page for a recent closing price, trade volume, and value. A Treasury bond below 100 deserves investigation because the investor receives the contractual coupons and, if held to maturity and paid as agreed, receives 100 of principal for less than 100 of clean purchase price.
Consider a 15-year remaining bond with an 11.5% coupon trading at 97. For RWF 1,000,000 face value, clean consideration is RWF 970,000. The annual gross coupon remains RWF 115,000, or RWF 109,250 after an assumed 5% withholding rate. At maturity, the investor receives RWF 1,000,000, adding RWF 30,000 of pull-to-par value relative to the clean purchase price. In a simplified semiannual model, gross YTM rises to approximately 11.93% and after-tax YTM to approximately 11.35%, both above the nominal coupon comparison implied by price 100.
The discount is not automatically a bargain. It may reflect higher market yields, a seller's liquidity need, weak trading depth, or a quote that is no longer executable. Before treating the discount as opportunity, request a live bid or offer from BK Capital, confirm face value available, settlement date, accrued interest, commission, and any custody charges. Re-run YTM using the all-in dirty cash amount rather than the website closing price alone.
Level 3.3 · Primary market
A reopening allows the Government of Rwanda, through the National Bank of Rwanda, to issue an additional amount of an existing Treasury-bond series instead of creating an entirely new bond. The reopened tranche normally keeps the existing series' coupon rate and final maturity date. Because time has passed since the original issue and market yields may have changed, investors compete through the auction price or yield rather than receiving a newly reset coupon.
Imagine a 20-year FXD series originally issued with a 13.15% coupon. If BNR reopens it later, the additional bonds may have roughly 19 years remaining but still pay the original 13.15% coupon and mature on the original date. If prevailing required yield is below 13.15%, successful pricing may be above par. If required yield is above the coupon, pricing may be below par. The coupon headline therefore does not reveal the auction return; the accepted dirty price and resulting yield do.
Reopenings can make an existing bond series larger and easier to trade. They also let an investor buy long-dated cash flows without waiting for a brand-new maturity. Through a broker such as BK Capital, the investor should obtain the official reopening prospectus, auction timetable, bond code and ISIN, coupon dates, remaining tenor, minimum denomination, bidding instructions, settlement amount, and published auction result. The investor should verify that the new allocation is truly the same bond series rather than assuming it solely from a similar name.
Level 3.4 · Full analysis
Record the full bond name, ISIN or security code, original issue date, final maturity date, coupon rate, coupon frequency, and whether the row is an original issue or reopening. Similar FXD labels are not interchangeable, and two rows with similar coupons can have materially different remaining lives.
Treat the Fixed Income Board coupon and published YTM as reference fields. Look for a recent closing price and trading activity on the Bond Market page, then ask the broker for an executable quote. Record the observation time because a price without a timestamp can mislead.
List every future coupon date and the maturity principal. Do not assume all Rwanda Treasury bonds pay in January and July; each issuance follows its own schedule. Determine whether settlement occurs before or after the record-date conventions used by the paying system.
Convert quoted price into clean consideration, add accrued interest, then add broker commission and other confirmed charges. The all-in debit is the correct initial cash outflow for investor return calculations.
Use the actual settlement date and remaining payments. Solve once with contractual gross coupons and once with coupons reduced by the applicable withholding assumption. If no recent price exists, label any published-YTM tax adjustment as an approximation rather than a fully repriced result.
Compare remaining maturity with the investor's objective. A high yield with three years left may be useful for a three-year liability but weak for a 20-year income plan. A long bond locks the rate longer but carries greater price volatility if sold before maturity.
Recalculate at a higher purchase price, lower reinvestment rate, earlier forced-sale date, and delayed execution. Ask how much of the expected return comes from coupons, discount accretion, or an assumption that cannot be guaranteed.
Store the broker confirmation, prospectus, settlement amount, accrued interest, fees, tax withheld, coupon dates, and maturity date in the private portfolio. Tracking actual cash flows against the original expected schedule turns a theoretical yield into an auditable investment record.
A recent executable price below par, an after-tax YTM that remains strong after all costs, a long remaining runway, adequate issue size, confirmed coupon dates, and a maturity aligned with the investor's plan together form a stronger case than any single high coupon.
A stale closing price, no available seller, large accrued interest, an expensive premium, short remaining life, conflicting security identifiers, uncertain payment dates, or a maturity that forces an early sale can erase the screen's apparent advantage.
