Reference excerpt

The Johannesburg Interbank Average Rate (JIBAR) is the money market rate, used in South Africa. It is calculated as the average interest rate at which banks buy and sell money. Since 2022, SARB has also published ZARONIA as the reference rand-denominated overnight rate. JIBAR is calculated daily by the South African Futures Exchange as the average prime lending rate quoted independently by a number of different banks. The rate is available in one-month, three-month, six-month and twelve-month discount terms. In particular, the three-month JIBAR rate is used as a benchmark of short-term interest rate movements. The rate is calculated daily after all of the rates are received. It is calculated as a yield and then converted into a discounted rate. The JIBAR rate is available daily from Thomson Reuters. ZARONIA reflects the interest rate at which rand-denominated overnight wholesale funds are obtained by commercial banks. It is based on actual transactions and calculated as a trimmed, volume-weighted mean of interest rates paid on eligible unsecured overnight deposits. The calculation excludes the highest and lowest 10% of interest rates to smooth out outliers. It is published on a T+1 basis reflecting the previous day's activity.

Worked examples

Example 1 — a first encounter with Johannesburg Interbank Average Rate

Start with the simplest possible case. Write down what Johannesburg Interbank Average Rate claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Johannesburg Interbank Average Rate before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Johannesburg Interbank Average Rate ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Johannesburg Interbank Average Rate

In research: Johannesburg Interbank Average Rate appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Johannesburg Interbank Average Rate in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Johannesburg Interbank Average Rate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Finance in South Africa, Finance stubs, Interest rates, so understanding it makes those chapters shorter.
In everyday life: Look for Johannesburg Interbank Average Rate outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
