What Is a Fixed Deposit?
A fixed deposit (FD) is a financial instrument offered by banks that allows an investor to place funds for a specified period such as 30, 90, 180, or 365 days at an agreed interest rate. The investor earns a predetermined return and receives the principal plus interest at maturity.
Fixed deposits are widely used by Individuals, Corporates, Churches and foundations, Pension funds and institutional investors. They are valued for their simplicity, predictability, and relative safety.
Benefits of Fixed Deposits
Fixed deposits offer several advantages:
I. Predictable Returns – Investors know exactly how much they will earn at maturity.
II. Capital Preservation – Fixed deposits are considered low-risk instruments when placed with regulated banks.
III. Short-Term Investment Planning – They are ideal for managing idle funds or meeting short-term liabilities.
IV. Ease of Administration – No trading, valuation complexity, or market timing is required.
However, these benefits do not eliminate credit and institutional risk, which differentiates fixed deposits from government securities.
Fixed Deposits vs. Money Market Instruments
Although often used interchangeably in practice, fixed deposits and money market instruments are fundamentally different.
Feature Fixed Deposit Money Market Instrument
Issuer Commercial banks Government, financial institutions and other businesses
Risk Low, but not risk-free Virtually risk-free (T-bills) but the other institutions have some amount of risk
Benchmark Should reference T-bill rate Treasury bill is the base
Liquidity Limited until maturity Highly liquid (T-bills) Limited until maturity
Examples Bank FD Treasury bills, commercial paper
Treasury bills, issued by the Government of Ghana, are universally accepted as the risk-free benchmark rate because they are backed by the sovereign. This makes Treasury bills the base rate of the financial system.
Why Fixed Deposit Rates Should Not Be Lower Than Treasury Bill Rates
In any efficient financial market, no rational investor should accept a lower return for higher risk. Yet, in Ghana, banks routinely offer fixed deposit rates that are significantly below Treasury bill rates.
This practice is economically illogical for three key reasons:
I. Treasury Bills Are Risk-Free
a. Fixed deposits carry bank credit risk, liquidity risk, and systemic risk.
II. Risk Must Be Rewarded
a. A bank deposit should attract a risk premium, not a discount.
III. Rate Suppression Distorts Capital Allocation
a. Cheap deposits enable banks to invest heavily in government securities instead of lending to the real economy.
The Pension Fund Distortion: A Ghanaian Example
In Ghana, National Pensions Regulatory Authority (NPRA) guidelines mandate that approximately 35% of pension fund assets be invested in bank money market instruments.
However, in practice:
• Banks are not issuing true money market instruments
• Instead, they are offering fixed deposits
• These fixed deposits are priced far below prevailing Treasury bill rates
The consequence is troubling:
• Banks mobilize long-term pension funds at artificially low rates
• They then reinvest these funds into Treasury bills and government securities
• This results in risk-free arbitrage profits for banks
• Meanwhile, SMEs, manufacturers, agribusinesses, and infrastructure projects struggle to access financing
In effect, pension funds meant to support national development are being used to subsidize bank balance sheets, not to grow the economy.
Why Banks Must Offer Rates above Treasury Bill Yields
If banks are required through regulation, market discipline, or institutional investor pressure to offer fixed deposit and money market rates above Treasury bill rates, the structure of incentives would change fundamentally.
I. End of Easy Arbitrage
a. Banks can no longer profit simply by recycling deposits into government securities.
II. Forced Reorientation Toward Productive Lending
a. To remain profitable, banks must finance:
b. SMEs
c. Manufacturing
d. Agribusiness
e. Infrastructure
f. Trade and export businesses
III. Revival of Financial Intermediation
a. Banks return to their core function: mobilizing savings and allocating capital efficiently.
IV. Job Creation and Economic Growth
a. Credit to productive sectors translates directly into employment and income generation.
Policy Implications and the Way Forward
To correct the current imbalance, the following actions are necessary:
• Clear distinction between fixed deposits and money market instruments
• Enforcement of risk-based pricing relative to Treasury bills
• Stricter NPRA oversight on how pension funds are placed with banks
• Encouragement of genuine bank-issued money market instruments
• Incentives for SME and project financing
Fixed deposits remain a valuable savings and investment instrument. However, when fixed deposit rates are priced below the Treasury bill rate, the financial system becomes distorted.
In Ghana, this distortion has allowed banks to earn risk-free profits on pension funds, while the productive sectors of the economy are aggressively searching for capital to expand, innovate, and create jobs.
Treasury bills are the base rate of the economy. Any investment instrument that carries higher risk must be priced above the risk free asset. When banks are compelled to do so, they will naturally shift away from passive government lending and toward financing the real economy where sustainable growth truly comes from in the economy.
