Repo Rate, Inflation, the Rand and Petrol: How They Hit Your Wallet

THE PULSE PILLAR GUIDE Economy Series

Thepulse

A plain-language guide to the economic numbers South Africans hear about and how each one affects your bond, groceries, fuel and savings.

South Africans hear economic terms constantly: the repo rate, inflation, the rand, the fuel price, the budget. They are often reported as if everyone already knows what they mean. This guide explains the main ones in plain language and shows how each connects to the money in your pocket. Once you see how they link together, the news makes a lot more sense.

The repo rate and prime

The repo rate is the interest rate at which the South African Reserve Bank (SARB) lends money to commercial banks. It is set by the Bank's Monetary Policy Committee at scheduled meetings during the year. Banks then add their own margin to set the rate they charge you. The prime lending rate in South Africa is generally the repo rate plus 3.5 percentage points. Home loans, vehicle finance, credit cards and overdrafts are usually linked to prime.

What a rate change means in rands

Here is an illustration. On a R1 million home loan over 20 years, a rise in the interest rate from 11% to 12% adds roughly R700 to the monthly repayment. A fall of the same size lowers it by about the same amount. If you have a variable-rate bond, even small changes matter.

The flip side is that higher rates reward savers. When rates rise, banks pay more interest on savings and fixed deposits, though usually less than they charge on loans.

Inflation

Inflation measures how fast the general level of prices is rising. Statistics South Africa tracks it every month using the Consumer Price Index (CPI), which prices a basket of goods and services such as food, transport, housing and clothing. If inflation is 5% a year, something that cost R100 a year ago costs about R105 today.

The SARB aims to keep inflation within a target range. When prices rise too fast, it can raise the repo rate to cool spending. When inflation is low and the economy is weak, it can cut the rate to encourage borrowing and growth.

Why your inflation is not the official inflation

The headline figure is an average. If you spend more of your budget on food and transport, as many lower-income households do, rising food and fuel prices can hit you harder than the headline number suggests.

The rand

The rand's value against currencies like the US dollar changes every day. South Africa imports many things, including fuel, electronics, machinery, medicines and some food, and pays for them in foreign currency. When the rand weakens, imports cost more rand, and prices tend to rise. When the rand strengthens, imports get cheaper.

The rand reacts to many things: global investor mood, commodity prices, interest rates, political events, ratings decisions and South Africa's own economic data. That is why markets pay close attention to events such as budget statements and inflation releases.

How the petrol price is set

The petrol and diesel price is not set by oil companies at will. It follows a formula managed by the Department of Mineral and Petroleum Resources. The main parts are:

The basic fuel price (BFP): based on international prices of refined fuel and the rand-dollar exchange rate. This is the part that moves most from month to month.
Fixed levies and taxes: including the general fuel levy and the Road Accident Fund levy, which are set by government and change only when announced.
Margins and costs: such as wholesale and retail margins and transport costs.

Adjustments take effect on the first Wednesday of each month. In the weeks before, the Central Energy Fund publishes data showing whether the price is heading up or down, which is why newspapers carry forecasts. When international prices jump or the rand weakens, the effect shows up at the pump the following month.

Why fuel affects everything

Fuel moves food to shops, workers to jobs and goods to ports. When it rises, transport costs follow, and then the price of almost everything else. That is why a fuel price rise is felt even by people who do not own a car.

The Budget and the MTBPS

The national Budget, delivered by the Finance Minister around February, sets out how government will raise and spend money. The Medium-Term Budget Policy Statement, usually delivered in October or November, updates those plans and gives a mid-year picture of the economy, the deficit and government debt. Investors and ratings agencies use it to judge whether the country's finances are on track. A good outlook can strengthen the rand and lower borrowing costs. A poor one can do the opposite.

How it all connects

Oil prices rise or the rand weakens, so fuel and imported goods cost more.
Transport and food prices climb, so inflation rises.
If inflation stays high, the Reserve Bank may raise the repo rate.
Higher rates make bonds and loans costlier, which slows spending and borrowing.
A stronger rand or lower oil price can reverse the chain.

What you can do

If you have a bond or loan, know your rate and keep a buffer for increases. Paying a little extra when you can reduces the total interest.
If you save, compare interest rates regularly. Savings that earn less than inflation lose value.
If your budget is tight, plan for fuel and food increases, and shop around.
Watch the calendar. Repo decisions, CPI releases, fuel announcements and budget statements are all published in advance.
