With annualised returns of around 4.5% reported by some funds, money market funds are becoming an increasingly relevant option for investors in the Sultanate of Oman. OERLive examines how they work, their potential returns, the risks involved and whether they offer a meaningful alternative to traditional savings and fixed deposits.

For thousands of individuals in Oman, financial planning begins with a familiar decision: should surplus money remain in a savings account, be locked into a fixed deposit or be invested elsewhere?

While equities, real estate and (relatively-safer) cryptocurrencies offer opportunities for long-term wealth creation, they also introduce varying degrees of volatility and uncertainty. For investors seeking relatively stable returns without committing their savings for extended periods, money market funds provide another option.

These funds invest primarily in short-term financial instruments, including bank deposits, treasury bills, certificates of deposit and other debt securities. Their objective is to generate income while preserving capital and maintaining liquidity.

Their relevance is also growing alongside Oman’s broader investment-fund industry. According to figures released by the Financial Services Authority (FSA) in July 2026, the combined capital of investment and real estate funds in Oman increased by 89.9% to approximately OMR 1.2 billion in 2025, compared with OMR 630.8 million in 2024.

Investment funds alone accounted for OMR 993.7 million, representing an increase of 125.4% from the previous year. And although these figures represent the broader fund industry rather than money market funds specifically, they highlight the expansion of professionally managed investment products in the Sultanate of Oman.

Understanding how a money market fund works

A money market fund pools capital from multiple investors and places it in a portfolio of short-term financial instruments. Instead of an individual placing OMR 1,000 in a single bank deposit, for example, the money is combined with capital contributed by other investors. Professional fund managers then allocate the pooled amount across eligible investments, assessing factors such as creditworthiness, interest rates, maturity periods and liquidity.

Investors receive units in the fund, with each unit representing a proportional interest in its underlying assets. As these assets generate income, the fund’s net asset value (NAV) can increase. Investors benefit through appreciation in their units or through distributions, depending on the fund’s structure and policies.

Unlike conventional fixed deposits, however, the returns are not predetermined – and the value of an investment can fluctuate, and the original capital is not guaranteed. Money market funds are designed to manage risk conservatively, but they remain investment products rather than conventional bank savings accounts.

What are money market funds earning in Oman?

Bank Muscat’s Money Market Fund, established in June 2012, provides a useful example of how these products perform. Per the bank’s published figures as of July 31, 2026, the fund generated annualised returns of 4.46% over one month, 4.50% over three months, 4.54% over six months and 4.61% over 12 months.

These figures require careful interpretation. An annualised one-month return of 4.46% does not mean an investor earned 4.46% in a single month. It represents that month’s performance expressed as an equivalent annual rate.

The 12-month figure of 4.61% is a historical annualised return, not a guarantee that the same performance will continue. Nevertheless, it provides a practical benchmark for understanding potential earnings.

Assuming an investor earns a constant annual return of 4.61%, the following amounts illustrate the income that different investment levels could generate:

• OMR 500: approximately OMR 23.05 annually.
• OMR 1,000: approximately OMR 46.10 annually.
• OMR 5,000: approximately OMR 230.50 annually.
• OMR 10,000: approximately OMR 461 annually.
• OMR 25,000: approximately OMR 1,152.50 annually.

These calculations are illustrative, assume no additional contributions and do not account for changes in returns or compounding. They also do not imply guaranteed monthly distributions.

For an investor holding OMR 10,000, an annual return of 4.61% translates into approximately OMR 38.42 per month when the annual earnings are divided by 12. And for someone investing just OMR 500, the monthly equivalent is approximately OMR 1.92.

The numbers reveal an important characteristic of money market investing: the financial benefit depends heavily on the capital available.

At smaller investment amounts, the returns may seem modest. For individuals or businesses holding substantial idle cash, however, the accumulated income can become more meaningful.

Why are the returns changing?

Money market funds are closely linked to prevailing short-term interest rates, so when interest rates rise, newly acquired deposits and debt instruments may offer higher yields. Conversely, falling interest rates can reduce the income available when existing investments mature and are replaced.

Bank Muscat’s published historical figures illustrate this relationship. As of June 30, 2025, its Money Market Fund reported an annualised one-month return of 5.01%. By July 31, 2026, the corresponding figure had declined to 4.46%.

That represents a reduction of 0.55 percentage points. For an investor holding OMR 10,000, the difference between annual returns of 5.01% and 4.46% amounts to OMR 55, assuming either rate remains constant for a full year.

This comparison does not establish what the fund will earn in the future. It demonstrates that even relatively conservative investment products are sensitive to changing market conditions.

It also raises an important consideration for investors: a money market fund offering approximately 4.5% today may generate a different return six or 12 months later.

Unlike a fixed deposit with an agreed interest rate, investors cannot assume that the current yield will remain unchanged throughout their investment period.

Money market funds versus fixed deposits: where does the advantage lie?

The main attraction of a fixed deposit is the certainty of an agreed interest rate for a specified tenure, subject to the bank meeting its obligations. A money market fund offers a different proposition: variable returns combined with the ability to request redemption, generally on business days.

Consider an investor with OMR 10,000. If a bank offers a hypothetical fixed-deposit rate of 4% annually, the investor could earn OMR 400 over one year, assuming the deposit remains in place for the agreed period.

At an assumed money market fund return of 4.61%, the equivalent annual earnings would be OMR 461 – the difference is OMR 61.

Over six months, the additional return would be approximately OMR 30.50, assuming simple interest and unchanged rates. This illustrates why investors should avoid evaluating these products on headline yields alone.

An additional OMR 61 annually on a OMR 10,000 investment may be attractive, but the investor must also consider capital protection, liquidity requirements and whether the fund’s return could decline.

The liquidity advantage can be particularly relevant for individuals saving towards property purchases, vehicle down payments, school fees or other expenses whose precise timing is uncertain.

With Bank Muscat’s Money Market Fund, subscriptions and redemptions are available on business days, and the bank provides digital access through its mobile and internet banking platforms.

Its published documentation also specifies that redemption requests are subject to processing arrangements and cut-off times.

Daily liquidity therefore does not mean that money can necessarily be withdrawn instantly. Investors should retain immediately accessible cash for emergencies rather than treating a money market fund as a direct replacement for their primary bank account.

The hidden importance of fees

Investment returns must also be considered after accounting for management and operating expenses. Bank Muscat’s November 2025 factsheet specified an annual management fee of 0.50% for its Money Market Fund. On an investment of OMR 10,000, this is equivalent to approximately OMR 50 annually, assuming the investment value remains constant.

Other administrative and operating expenses may also apply. However, investors should distinguish between gross and net returns.

When a fund publishes performance calculated from its NAV after applicable expenses, those expenses have already affected the reported performance. It would therefore be incorrect to automatically deduct the management fee again from a NAV-based return.

Investors should verify how each fund calculates its published returns before comparing products. Bank Muscat’s published mutual-fund FAQ also states that its Money Market Fund does not impose subscription or redemption fees. Investors should nevertheless consult the latest prospectus and fee schedule because fund terms can change.

Diversification does not eliminate risk

One benefit of money market funds is that they can spread investments across several banks, financial institutions and debt instruments. This can reduce dependence on a single counterparty, however, diversification does not eliminate the possibility of losses.

Bank Muscat’s November 2025 factsheet showed that approximately 69% of its Money Market Fund portfolio was allocated to Oman, 30% to the wider GCC and 1% internationally.

The same factsheet showed currency exposure of approximately 60% in Omani rials and 40% in US dollars. These figures provide insight into the underlying portfolio, demonstrating that the fund’s investments were concentrated geographically in Oman and the GCC at that time.

Investors should examine such exposures alongside the creditworthiness and maturity of underlying instruments. Credit risk arises when a bank or another issuer fails to meet its financial obligations. Liquidity risk emerges when assets cannot be sold or redeemed promptly without potential losses.

Interest-rate movements can also influence returns, while inflation may reduce the purchasing power of investment gains.

For example, an investment generating a nominal annual return of 4% during a period of 5% inflation would still lose purchasing power despite recording a positive monetary return. Money market funds may generally experience less volatility than equity funds, but we won’t describe it as risk-free.

Are money market funds protected by deposit insurance in Oman?

This is actually among the most important distinctions for investors. The Central Bank of Oman’s Banking Deposits Insurance Scheme provides coverage of up to OMR 20,000 per depositor per member bank for eligible deposits, subject to the scheme’s conditions.

Eligible categories include conventional savings, current and time deposits. Money market fund units are investments rather than eligible bank deposits and do not receive the same protection.

This remains true even when the fund is managed or distributed by a major commercial bank. The distinction becomes particularly relevant when investors compare a money market fund with a conventional fixed deposit.

The fund may offer greater flexibility or a potentially different return, but investors must recognise that the regulatory and capital-protection arrangements are not identical.

A growing market for short-term investment products

Oman’s financial sector now offers different money market investment structures. Alongside Bank Muscat’s conventional fund, the National Bank of Oman has introduced a money market product, while ahli Bank offers a Sharia-compliant alternative.

The ahli Islamic Money Market Fund’s March 2026 factsheet reported a running yield of 4.6%, a minimum subscription of OMR 500, daily dealing and a one-business-day redemption notice.

Its investment approach uses Sharia-compliant instruments rather than conventional interest-bearing securities. However, a running yield and a historical total return are different performance measures. Investors should not compare them directly without examining their calculation methods, reporting dates and applicable expenses.

The existence of multiple offerings expands investor choice, but it also increases the importance of understanding the differences between products.

Minimum investment requirements, portfolio composition, currency exposure, fee structures and redemption arrangements can vary substantially.

What role should money market funds play in an investment portfolio?

Money market funds are primarily designed for short-term liquidity management and income generation. They can serve individuals who want to earn potential returns on savings earmarked for future expenses without exposing the entire amount to equity-market fluctuations.

Businesses may also use them to manage temporary cash surpluses before meeting operational requirements. However, their role differs from that of long-term growth investments.

Over extended periods, equity investments may offer greater growth potential, although they also expose investors to substantially different risks and periods of potentially significant losses.

Money market funds are generally not designed to deliver aggressive capital appreciation. Their value lies in providing an intermediate option between immediately accessible cash and investments with longer time horizons or greater market volatility.

For investors holding money that may be needed within the next several months, the ability to earn income while maintaining relatively flexible access can be valuable.

For individuals who require absolute certainty over the amount available on a particular date, the absence of a capital guarantee must receive greater consideration.

The bigger picture: making Oman’s savings more productive

The development of money market funds has implications beyond individual investment decisions. By pooling capital and directing it into short-term financial instruments, these funds provide additional channels for managing liquidity within the financial system.

They also allow retail investors to access professionally managed portfolios that might otherwise be difficult to construct independently.

The expansion of collective investment products contributes to the broader development of Oman’s capital markets and the mobilisation of domestic savings, supporting the financial-sector development objectives of Oman Vision 2040.

However, the growth of the fund industry should not be confused with evidence that every product is appropriate for every investor. A money market fund’s attractiveness ultimately depends on the relationship between the income it generates, the risks it assumes and the accessibility of invested capital.
