Why Your Emergency Fund Should Not Be in a Savings Account

The standard advice — keep three to six months of expenses in an emergency fund — is sound. The standard implementation of that advice — a standard savings account at your primary bank — is not. South African bank savings accounts typically pay between 3.5% and 5.5% nominal interest per annum. With CPI running above 5%, the real return on that account is negative to flat. Your emergency fund is shrinking in real terms every month it sits untouched.

What an Emergency Fund Needs to Do

An emergency fund has two non-negotiable requirements: it must be available quickly (within one to five business days), and it must not lose its nominal value. Beyond those requirements, there is no reason it should not earn a competitive return. The question is simply: what instruments offer near-immediate liquidity with better yields than a savings account?

Money Market Funds

A money market unit trust invests in short-term, highly rated fixed income instruments: treasury bills, call deposits, NCDs (negotiable certificates of deposit) and similar instruments. Returns track the short-term interest rate environment closely — currently in the range of 8–9% for well-managed South African money market funds. Capital is not guaranteed (it is not a bank deposit), but South African money market funds have not broken the rand (lost capital) in modern memory.

Access is typically same-day or next-business-day for most retail platforms. Regulatory requirements limit the weighted average maturity of money market portfolios to 120 days, which keeps the liquidity risk extremely low. For an emergency fund, this is a materially better vehicle than a savings account, with minimal additional risk.

32-Day Notice Accounts

Several South African banks (and some non-bank providers) offer 32-day notice accounts paying significantly above savings account rates — typically prime minus 1% to prime flat, depending on the balance and provider. Technically, you must give 32 days' notice before withdrawing, but in practice, most providers allow early withdrawal with a penalty equivalent to 32 days of interest. The net return, even with a penalty, is often higher than a standard savings account rate.

For an emergency fund, the 32-day notice structure is manageable if you maintain a secondary, immediately accessible float (one month of expenses in a transactional account) alongside the larger notice account. The notice account earns the higher rate; the float covers any immediate needs while you serve the notice period.

The Tax Consideration

Interest income from money market funds and notice accounts is subject to income tax. The first R23,800 of interest per annum (R34,500 for those over 65) is exempt. Above that threshold, interest is taxed at your marginal rate. For comparison, bank savings account interest is taxed identically — so the tax treatment does not change the relative advantage of higher-yielding alternatives.

Reviewing your emergency fund placement is a simple, low-effort financial improvement. Moving R150,000 from a 4% savings account to an 8.5% money market fund saves approximately R6,750 per annum in lost returns — without any meaningful increase in risk or reduction in availability.
