What fixed deposit means
A fixed deposit is a loan you make to a bank on agreed terms.
You place a sum for a stated period, commonly thirty, ninety, one hundred and eighty or three hundred and sixty five days, at a rate agreed at the outset. At maturity the bank returns the principal with the interest.
The rate is higher than a savings account because the bank knows how long it has the money. In exchange you give up access. Breaking the deposit early normally means losing some or all of the accrued interest, and the terms of that penalty are set in the deposit agreement.
The credit risk is the bank's rather than the government's, which distinguishes it from a treasury bill. That risk is mitigated by the deposit insurance framework operated by the Nigeria Deposit Insurance Corporation, which covers deposits in licensed institutions up to the applicable limit.
Withholding tax applies to the interest, so the net return is lower than the quoted rate suggests.
How it is used
Fixed deposits suit money with a known date attached.
A business holding funds for a tax payment due in four months. A family saving for school fees. A company parking surplus cash between projects. In each case the money is not needed now, the date it is needed is known, and the objective is safety with some return.
The terms worth reading before placing one are short.
The rate, and whether it is quoted per annum even though the tenor is ninety days, which it usually is. A rate of eighteen percent per annum on a ninety day deposit earns roughly a quarter of that over the period.
The early liquidation penalty. What you actually receive if you need the money in month two.
The rollover instruction. Whether it rolls automatically at the prevailing rate, and whether that rate is the one you would accept.
And whether the deposit is being placed with a licensed institution. That is what brings deposit insurance into play, and it is the difference between a bank deposit and an arrangement with an unlicensed operator promising a higher return.
Key features
- Money placed with a bank for a fixed period at an agreed rate
- Higher rate than a savings account in exchange for giving up access
- Early liquidation normally forfeits some or all accrued interest
- Credit risk is the bank's, mitigated by NDIC insurance up to the applicable limit
- Rates are usually quoted per annum regardless of the tenor
- Withholding tax applies to the interest earned
How this works in Nigeria
Three practical points matter for a Nigerian saver.
The first is the real return. A nominal rate that looks attractive can still be a loss in purchasing power where inflation exceeds it, and Nigerian savers have experienced that for extended periods. A fixed deposit protects the naira figure. It does not protect what that figure buys.
The second is the institution. Deposit insurance covers licensed banks up to the applicable limit per depositor per institution. That limit matters for anybody holding a substantial sum, and spreading across institutions is the standard response. An arrangement with an unlicensed operator offering a far higher return is not a fixed deposit and carries no such protection, and Nigerians have lost significant sums to exactly that.
The third is negotiation. Rates on larger deposits are negotiable, and a business placing a meaningful sum should ask rather than accept the counter rate. The published rate is a starting point.
On early liquidation, the penalty terms vary between banks and are stated in the deposit agreement. A depositor who may need the money should ask specifically what they would receive at day thirty rather than assuming they simply lose the interest for the remaining period.
Fixed deposit vs treasury bill vs savings account
Three ways to hold naira, differing in access, risk and return.
A savings account gives full access at any time and pays the least. It is for money you may need tomorrow.
A fixed deposit locks the money for a term at a higher rate. The credit risk is the bank's, mitigated by deposit insurance up to a limit. Early access costs you interest.
A treasury bill is short term government borrowing, sold at a discount and redeemed at face value. The credit risk is the Federal Government's, which is lower than any bank's, and it can be sold on the secondary market before maturity at the prevailing price.
For a business with a known date and a moderate sum, a fixed deposit is simple and often competitive. For a larger sum where credit risk matters, a treasury bill. Compare on true yield after withholding tax rather than on quoted rates.
Limits and risks
Access is the trade off. Money in a fixed deposit is not available without cost, and a business that placed its buffer in one has removed its own flexibility.
Inflation erodes the real value, and a positive nominal return can be a negative real one.
Deposit insurance covers up to a limit, so a large depositor carries uninsured exposure to the institution above it.
Rates are also set by conditions rather than need, and a saver requiring a particular return will not obtain it from a deposit priced by the market.
And automatic rollover can trap a depositor at a rate they never agreed to, simply because nobody looked at the maturity notice.
Worth knowing
Check whether the quoted rate is per annum and what the early liquidation terms actually pay. Nigerian savers place ninety day deposits expecting the full headline rate over the period, and then discover both the pro rating and the penalty at the same time when they need the money early.
Questions people ask
What is a fixed deposit?
Money placed with a bank for a fixed period at an agreed rate. The bank returns the principal with interest at maturity, and early access normally costs some or all of the accrued interest.
Is the quoted rate what I earn over the term?
Usually not. Rates are typically quoted per annum regardless of the tenor, so an eighteen percent rate on a ninety day deposit earns roughly a quarter of that over the period.
Are fixed deposits insured in Nigeria?
Deposits in licensed institutions fall within the deposit insurance framework operated by the Nigeria Deposit Insurance Corporation, up to the applicable limit per depositor per institution.
What happens if I break it early?
You normally forfeit some or all of the accrued interest, on terms set out in the deposit agreement. Ask specifically what you would receive at an early date rather than assuming.
Fixed deposit or treasury bill?
A treasury bill carries government rather than bank credit risk and can be sold before maturity on the secondary market. A fixed deposit is simpler and often competitive for moderate sums. Compare on true yield after withholding tax.
Can I negotiate the rate?
On larger deposits, yes. The published rate is a starting point, and a business placing a meaningful sum should ask rather than accept the counter rate.
