The sudden hike of import tariffs by US President Donald Trump and his administration to countries across the world is set to reduce the volume of goods traded and affect citizen welfare across the globe. The Trump administration implemented a global 10% import tariff and a varying targeted reciprocal tariff to a host of countries, including South Africa. The reciprocal import tariff to be levied on South African export goods to the US is set at 30%. Historical data show that yearly trade between SA and US amounts to $23 billion and the US is SA’s the second biggest trading partner after China. The high tariff will reduce the competitiveness of South African export goods to American markets, leading to reduced demand of SA exports in US markets, low income to firms, job losses, low income to households and ultimately lower South African economic growth.

 

SA and US trade

South Africa exports platinum, locally assembled cars, raw aluminium, ferroalloys and agriculture products, among other goods, to the US. The implication of the US administration’s 30% tariff hike could result in job losses in the mining, automobile, agriculture and many other industries. More income losses to SA agricultural exports can also be experienced if the African Growth Opportunity Act (AGOA) expires in September 2025, if the US congressmen decide not to renew the agreement. Given the low economic growth rate in South Africa in 2024, which is estimated at 0.6%, the tariff hike by the US will exacerbate sluggish economic growth and recovery from the COVID 19 pandemic. 

Statistics also show that SA imports energy products, machinery, vehicle, industrial and other consumer goods. The goods and services SA imports from the US play a critical role in developing and sustaining local industry. SA can decide to source the goods from other markets and if this happens with all economies where tariffs were imposed, the US will be worse off. There is a possibility that economies which received a tariff hike from the US will implement a reciprocal tariff hike to the US reducing the volume of global trade. The reduced trade volumes have dire implications for job creation, income generation by firms and households, making citizens worse off.


US current trade policy

It is important to note that President Trump administration’s trade policies are premised on a trade notion synonymous to ‘mercantilism’, which was practised in Europe between the 16th to 18th centuries. Under mercantilism, an economy aims to maintain a trade surplus, the government regulate the economy, discourage imports (in the case of the US using tariff hikes) and promote growth of home industries among other initiatives. Conventional economics wisdom has proved that policies pursued by the Trump administration of protectionism are a breeding ground for trade wars. There is great potential of fellow trading partners retaliating and if that happens, global citizens will be made worse off as they will be forced to pay high prices for goods due to additional costs driven by tariff hikes. In addition, US industry relies on raw materials from other countries. If the suppliers of raw material resources retaliate, the production cost model of US firms will rise, reducing export competitiveness of US exports.

Trump’s administration is calling for firms across the world to move and produce goods in the US to avoid tariff levies. The action works against the benefits of free trade and can affect firms’ comparative advantages. The production cost structure in the US can be higher than in other countries leading to firms realising low profits if they move to the US. It is essential to note that free trade with absolutely no trade barriers will enhance the welfare of citizens at large, since goods and services will be purchased at low prices. The US government’s act of over-regulating trade can limit economic growth not only of other countries but even that of the US economy.

 

Options for the SA government

In the face of trade adversity, the SA government must not fold its hands and do nothing. It is enlightening to note that the authorities have already initiated diplomatic and trade negotiations. Negotiations can possibly focus on tariff reduction, maintaining the AGOA, and delving deep in the logic used to arrive at the 30% tariff hike. The diplomatic initiatives must encompass improving perceptions and clarity of SA policies such as the Expropriation Act which is one of the reasons cited by the US administration in ratcheting the tariff trade war.

South Africa must re-orient its trading patterns and partnerships. The aggregate world gross domestic product (GDP) is greater than the US total production for goods and services. There is need for SA to improve trade relations with other economies to broaden its trade base. The current frosty trade relationship between SA and the US presents a window to strengthen trade with the EU, Asia, BRICS plus, Africa, and any other economy willing to get into trade partnerships. SA must explore other markets where the export goods still enjoy competitiveness.

To ensure economic resilience to trade wars in the long run, SA needs to seriously invest in research and development that promote value addition of local production, enhancing local production and technology advancement that can stimulate economies of scale, which can boost competitiveness of export goods. Competitiveness can be further enhanced by improving energy production efficiency, which is a crucial input of goods and services production. Developing a powerful and skilled human capital base can lead to labour productivity efficiency, further enhancing competitiveness. SA has a dilapidated infrastructure ranging from roads, rail, buildings and industry among others. Improving the infrastructure will go a long way in improving local production, leading to creation of jobs and improved incomes for households.

Boosting local economic activity can stimulate local consumption of goods as household income improves. If the incomes of SA citizens improve, there is a potential to increase local consumption. Goods meant for export markets can end up being consumed in the domestic markets, providing a homemade solution to dwindling export goods markets. The SA government must consider developing and supporting new industries that can compete in the local and international markets. In this way, the trade challenges posed by unfriendly US administration trade policies can present opportunities to the SA economy in the long run.

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.
