Nigeria’s economic system is in a tightening part.
The Central Bank of Nigeria has raised charges a number of instances in latest months as a response to persistent inflation, elevated authorities borrowing and stress on the naira.
Though there was a pause in February 2025, the broader pattern stays upward. Whereas these coverage strikes are designed to stabilise costs and handle extra liquidity, in addition they have clear penalties for buyers, particularly these targeted on fixed-income devices.
On this piece, the impression of rates of interest on fixed-income devices is mentioned to present buyers the mandatory context for prudent portfolio choices.
Rates of interest are among the many most consequential variables in fixed-income investing. Once they rise, their results are instantly felt throughout fastened revenue merchandise, fund valuations, and reinvestment methods. A transparent understanding of this relationship is vital for buyers managing fixed-income portfolios.
One of the vital noticeable tendencies in fixed-income investing is that this: when rates of interest go up, bond costs often go down. Why is that this the case?
A bond is principally a mortgage. Whenever you purchase one, you might be lending cash to an organization or the federal government, and they comply with pay you curiosity, sometimes semiannually. This curiosity known as a coupon. Suppose you purchase a bond for ₦1,000,000 with a ten% coupon and a 5-year maturity. This implies:
So, in complete, you’ll have obtained ₦1,500,000: ₦1,000,000 in principal (your preliminary capital) + ₦500,000 in curiosity revenue.
This construction, regular revenue plus eventual return of your capital, is what makes bonds engaging to many buyers, particularly when they need predictable money flows.
Now, right here is the vital half: if new bonds available in the market are actually providing increased coupons, say, 14% as a substitute of 10%, buyers will choose these. Your older bond, which pays simply 10%, will now not look like a very good deal.
Which means that, if you need to promote your bond earlier than it matures, you would need to promote at a reduced worth to draw patrons. That method, although your bond pays much less annually, the discounted worth means the client receives a bigger quantity of the bond and nonetheless will get a return (or yield) that’s near the brand new market fee.
For this reason bond costs fall when rates of interest rise, in order to stay aggressive with newer bonds that pay extra curiosity.
The diploma of sensitivity to rate of interest adjustments is dependent upon the construction of the fixed-income instrument:
What’s mark-to-market valuation?
The phrase “mark-to-market” comes from the thought of marking (or recording) the worth of one thing primarily based in the marketplace worth at present.
Say you personal a desk; you got it for ₦50,000 final 12 months. However at present, somebody provides to purchase it from you for ₦35,000. If you wish to present how a lot your desk is price proper now, you don’t write down ₦50,000 anymore. You “mark it to the market,” which means that you just replace the worth to mirror what somebody is definitely keen to pay at present: ₦35,000.
This concept could be utilized to fixed-income funds, that are swimming pools of cash invested in fixed-income securities and cash market devices. When rates of interest rise, the value of lots of these securities falls. As an alternative of ready till the bond matures to see what it’s price, fund managers must report what the bonds might be bought for proper now, that’s, at present’s market worth. That is what mark-to-market means.
So even when the fund remains to be accumulating coupon funds on these bonds (say, ₦100,000 a 12 months), the general worth of the fund may briefly drop as a result of these bonds would promote for much less within the present market. This drop exhibits up in what known as the fund’s Internet Asset Worth (NAV), which principally is the fund’s present price per unit.
The advantage of mark-to-market valuation is that it helps hold issues clear for buyers, so they can make knowledgeable choices.
Rates of interest and fixed-income investments transfer in reverse instructions. When rates of interest rise, the costs of current fixed-income securities fall. This dynamic is central to how buyers handle fixed-income portfolios, particularly in an setting like Nigeria’s, the place inflationary stress and financial coverage adjustments can shift rapidly.
The primary precept to bear in mind is that fixed-income securities with shorter maturities are usually much less affected by rate of interest will increase. It is because their costs would not have to regulate as a lot to stay engaging, as buyers will quickly have an opportunity to reinvest at newer, increased charges.
Take into account this situation: you have got two bonds to select from:
Now, think about that rates of interest available in the market rise to 14%.
Bond A could lose a little bit worth. Say, it now trades at ₦980,000 as a substitute of ₦1,000,000. However Bond B, with its longer tenor, may see its worth drop extra sharply, maybe to ₦920,000.
This distinction issues. If you’re a person investor who may have to promote earlier than maturity, Bond A protects you higher from worth swings. Even should you plan to carry till maturity, shorter-term devices provide you with extra flexibility to reinvest at increased charges as they mature.
It’s simple to panic when bond or fund values drop on paper. However for a lot of buyers, the first good thing about fastened revenue is the regular stream of curiosity funds. Except you propose to promote early, the headline worth actions don’t change the revenue you’ll obtain.
Instance:
You buy a company bond for ₦1,000,000 with a 13% coupon and a 5-year maturity.
Even when market rates of interest rise and your bond’s resale worth briefly drops to ₦950,000, your precise earnings stay the identical so long as you maintain the bond to maturity.
What’s the lesson right here? Don’t confuse worth volatility with actual losses. What issues is your means to remain invested and hold accumulating revenue.
Because the shorter-tenor devices mature, you may reinvest them on the new prevailing charges, doubtlessly enhancing total returns. On the identical time, you might be nonetheless accumulating coupons on the longer-term portion. This strategy offers you a stability between flexibility and stability.

When markets are unpredictable, going at it alone can really feel like driving by way of fog with out headlights. For a lot of particular person buyers, adjusting a fixed-income technique in response to rate of interest adjustments is less complicated stated than carried out. Rebalancing, laddering, and waiting for length danger all demand time, market perception, disciplined execution, and huge buying and selling capital.
