Opinion article by Prof Johan Coetzee (MCBI, CMBE), Chairperson: Department of Economics and Finance, University of the Free State.

The Minister of Finance has not had it easy in 2025 and the budget speech not read yesterday pays testament to this. Postponing the speech to 12 March is unprecedented, and is due to the Government of National Unity (GNU) not reaching consensus on a way forward to tabling a budget. It seems as if the fallout was based largely on a proposed 2% increase to VAT that was rejected by two parties. I personally would not have supported this proposal either as the tax burden shifts disproportionally to the poor.

My initial response of the postponement was frustration and disappointment. But I soon realised that it is the outcome of a new government dispensation made up of many voices, and many dissenting at that, becoming more important. In principle, this is good for the nation, but unfortunate for us expecting the budget to be read on the day. It also does not necessarily send a good message to the markets, with the rand weakening by more than 1% within an hour of the announcement. There could also be knock-on effects that a later tabling will have on service delivery and operations of government. After some reflection, however, I have concluded that on balance, the decision to postpone is not as problematic as many have made it out to be over the past 24 hours. Clearly there are many balls to juggle by Minister Enoch Godongwana and many added complexities that have both national and international dimensions.

Lead-up to the budget

Internationally the strong nationalist policy drive by US President Donald Trump has already shown that the ‘make America great again’ mantra is alive and well as reflected in the intentional actions taken against South Africa since his second term started in January. We will see how this plays out over the coming months, but my view is that South Africa as a nation needs to be more deliberate in its policy agenda. We are at an inflection point where we must reflect on who we are as a nation and where we want to be down the line. We cannot afford to rely on handouts from other nations. There is more opportunity to this situation than threat, but we need intentional leadership to exploit it.

My big concern in the lead-up to the budget speech was that the minister would not take a firm stand on fighting the culture of non-compliance within state entities which has invariably led to unsustainable levels of irregular expenditure. For the 2023/24 financial year, the Auditor-General of South Africa reported that irregular expenditure totalled almost R50 billion, up from just over R27 billion the previous year. To put this into perspective, irregular expenditure equals approximately 2.2% of total government spending for the 2023/24 fiscal year. This might not seem significant stated as a percentage, but it has basically doubled since the previous year, and every preceding year before that too. Moreover, irregular expenditure equates to approximately 20% of the 2023/24 social grants budget and just about equals the 2024 National Student Financial Aid Scheme allocation. This is clearly a management failure and nothing seems to have been done about it over the years. As a result, the problem is escalating at an alarming rate. It is quite astounding that accountability management is not more explicit as it is clearly a very unpopular political message to send. But at what cost?

South African economy is not growing

To make matters worse, the South African economy is not growing both enough and fast enough. The most recent real GDP growth figure showed a decrease of 0.3% in the third quarter from the second quarter of 2024. Since 1994, the period with the highest annual rate of growth was a three-year period from 2005 to 2007 where growth exceeded 5% for each respective year. This period preceded the global financial crisis and since then, growth has struggled to reach 3% annually, doing so on only two occasions barring the 4.7% in 2021 which was not a true reflection of reality given the low base of the preceding year amid the COVID-19 pandemic. This is a major concern for the Minister, because with economic growth comes increased tax revenues, which in turn capacitates better budget management. Very simply, the more people spend; the more businesses sell; the larger the profit outcomes; the larger the tax revenue collections. If the economy grows, the fiscus collects more tax revenues without explicitly increasing tax rates. This built-in cyclical dynamic is simply not happening and creates a serious constraint on the ability of the Minister to manage deficits going forward.

Further to this of course is that as deficits are run, all things remaining constant, public debt increases. The public-debt-to-GDP ratio for 2023/24 already exceeds 72% which is higher than the generally accepted benchmark of 60% and almost 2.6 times what it was in 2008 (27.8%). This has resulted in the average interest on public debt approximating R1.1 billion a day, equating to about 22% of total tax revenues, or almost 20% of total government spending respectively. To put it differently, for every R1 government spends, 20 cents is first channelled to pay the interest on the debt before any spending occurs on roads, education, infrastructure, social grants and the like. These are deeply concerning figures in an economy with already high levels of unemployment and inequality.

Might be beginning of something better

There is a leadership void that cannot be ignored anymore. It needs to be intentional and deliberate. The GNU provides the platform to exploit ‘the best that South Africa has to offer’ as it promotes a broad-based and more inclusive political structure and played itself out yesterday. I welcome this in principle, but my concern is that political in-fighting will prevail and perverse politicking will trump working together in the best interests of the South African people. Although the postponement could be interpreted negatively in terms of the GNU not being able to find common ground, I think it is rather a sign of more rigorous engagement and the enablement of a collaborative environment amongst parties in the decision-making structures of the state. Remember this day as it might be the beginning of something better than what we are used to.

Fight against Ebola virus requires more research
2014-10-22

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
