As has been the case for the past five years, the latest (2020) budget paints another sobering picture of South Africa’s public finances and short-term economic outlook. Of particular concern is that this budget does not project that the government debt ratio will stabilise in the medium term (by 2022/23), which means that the current fiscal policy trajectory is unsustainable (which National Treasury acknowledges in the Budget Review). This makes a rating downgrade by Moody’s in March all but inevitable. 

In the budget that was tabled on Wednesday, the budget deficit is projected to be 6,3% in 2019/2020, while increasing to 6,8% the following year, before gradually declining to a still unsustainable 5,7% of the GDP by 2022/23. These large budget deficits contributed to large projected increases in the government debt-to-GDP ratio: this ratio is projected to increase from about 62% in 2019/20 to about 72% by 2022/23. To understand the extent of the deterioration of South Africa’s public finances over the past 12 months, it should be noted that this ratio was projected in the 2019 budget to increase to about 60% by 2022/23.

Burger and Calitz (2020) show that the government debt-to-GDP ratio can be stabilised (and fiscal sustainability can be restored) if: the gap between real interest rates and real GDP growth is reduced, and/or if the primary balance (government revenues minus non-interest government spending) is adequate to avoid an increase in the debt ratio. They then show that the debt ratio has increased over the past decade because the (implied) real interest rate on government debt has increased and the real growth rate has decreased and government ran large primary deficits, at a time when large primary surpluses were required to avoid increases in the debt ratio. 

Between 1998 and 2007, the debt ratio was reduced from just under 50% to just under 30%. This period (especially from 2002 onwards) was characterised by (relatively) high economic growth. Fast economic growth is crucial to stabilising the debt ratio and restoring fiscal sustainability. National Treasury (NT) has proposed structural reforms (aimed at reducing regulatory burdens and backlogs and increasing competitiveness in the economy) to stimulate private sector investment and growth. Given the constraints that continued load shedding will put on South African growth in the near future, as well as projected slower growth in the economies of our main trading partners, and the uncertainties associated with disruptions wrought by the coronavirus outbreak, it remains to be seen if private sector investment will increase and stimulate growth (available evidence in any event suggests that private sector investment tends to follow, not lead, economic growth). 

With growth likely to remain slow, lower real interest rates and lower budget deficits are required to reduce the debt ratio and restore fiscal sustainability. These interest rates will more than likely increase if Moody’s decides to (finally) downgrade its rating of South African government debt.

With low economic growth and high real interest rates, stabilisation of the public debt ratio means that the budget deficit must be reduced. To reduce the budget deficit, government can: (i) increase taxes, (ii) decrease spending and (iii) increase taxes and reduce spending. Given that fiscal policy is unsustainable in South Africa, it is surprising that NT decided against increasing taxes (other than customary annual increases in the fuel levy and excise taxes) in this budget – many analysts were expecting some combination of higher personal income tax, VAT, and company taxes. As reasons for not raising taxes, it cites low expected economic growth, and that most of the efforts to reduce the budget deficit in the past five years have been centred on using tax increases. Even more puzzling, the budget granted real tax relief to taxpayers, as income tax scales were adjusted by more than expected inflation. 

All efforts to rein in the budget deficit therefore rely on government spending reductions. To this end, NT is proposing to reduce government spending by about R260 billion over the next three years. This reduction in spending is comprised of a R160 billion reduction in the wage bill, and a further R100 billion reduction in programme baseline reductions. At the same time, as a proposal for wage cuts, government is allocating even more money to prop up the balance sheets of many SoCs, with R60 billion allocated to Eskom and SAA (while the Minister referred to the Sword of Damocles when referring to SAA in his speech, a more apt analogy for government’s response to the financial crises facing many of its SoCs might rather be the paradox of Buridan’s ass). While government has announced plans for the restructuring of Eskom and has placed SAA in business rescue, so far there is no feasible consensus plan to address Eskom’s mounting debts and dire financial situation, which poses a systemic risk to the South African economy. 

Regarding the proposed reductions to the wage bill, NT believes that its target can be achieved through downward adjustments to cost-of-living adjustments, pay progression and other benefits. Furthermore, the Budget Review also states that pay scales at public entities and state-owned companies (SOCs) will be aligned with those in the public service to curtail wage bill growth and ‘excessive’ salaries at these entities. We are also told that government will discuss the options for achieving its desired wage bill reduction with unions. Given the precariousness of the public finances, and the understandable objections of workers and unions, one must ask why these discussions were not already in full swing by the time that the budget was tabled? 

Regarding the proposed cuts to government programmes, NT notes that it tried to limit these to underperforming or underspending programmes, and that the largest cuts will be in the human settlement and transport sectors. But, as NT acknowledges, any cuts to government programmes will negatively affect the economy and social services; the budget speech also states that the number of government employees has declined since 2011/12, which also affects the provision of public and social services adversely (the Minister explicitly mentioned increased classroom sizes, full hospitals, and too few police officers during his speech). 

Apart from the proposed spending cuts, the proposed allocation of spending is unsurprising and reflects long-standing government priorities: spending on basic education, post-school education and training, health and social protection takes up 13,6%, 6,7%, 11,8% and 11,3%, respectively. Increases in social grants range between 4 and 4,7%, which means small real increases in most social grants (only if inflation remains subdued). Worryingly, debt service costs are expected to take up more than 11% of total government spending (and is projected to exceed health spending by 2022/23). These costs are projected to grow by more than 12% by 2022/23 (almost double the growth in the fastest growing non-interest expenditure category). These figures vividly illustrate how a high and increasing debt-to-GDP ratio limits the scope for increased spending on important public and social services. 

Unless fiscal sustainability and the  balance sheets of SoCs are restored, the scope for the government to increase spending to combat poverty, rising inequality, and unemployment will be severely limited – as would the scope for countercyclical fiscal policy, should the local economy again slide into recession. The stakes are high, and the cost of indecisiveness is increasing.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
