South Africa Aims to Fire Up Economic Growth With Port, Rail Revival

South Africa$$s government and the business community set a target of boosting the economic growth rate by as much as six percentage points by fixing the country$$s collapsing ports and freight$-$rail network.

They predict that cracking down on crime and corruption may save as much as R$300$ billion

$($$$16$ billion$)$ a year, noted by Bloomberg and confirmed by business representatives. South

Africa$$s National Treasury has forecast that the gross domestic product will grow $1\%$ next year. South Africa$$s biggest companies and the government have set up joint panels as part of a drive by its biggest companies to work with the state to resolve a host of issues holding back the economy. These range from power cuts and the poor performance of the rail network, to increasing crime and an inefficient work$-$visa application process.

Coal shipments on South Africa$$s freight$-$rail network have plunged to $30-$year lows and iron$-$ore railings are at their lowest in a decade, prompting companies including Glencore Plc$,$ to consider cutting jobs. Port snarl ups are resulting in delays to the loading and offloading of ships and some fashion retailers have resorted to flying in apparel.

The problems are seeing $$mining companies reconfiguring in line with current reality and delaying capital investment, putting jobs at risk,$$ the National Logistics Crisis Committee said in the presentation. These include overall freight moved by rail increasing to $193$ million tons in the year through March $2025$ from $149$ million tons in the year to March $31,2023.$ Similarly ambitious targets have been set for the processing of containers at ports and the shipping of cars and bulk minerals.

The roadmap is a government document outlining plans to boost private involvement in the country$$s largely state$-$run ports and rail network. B$4$SA$,$ the business organisation helping coordinate the work with the government, didn$$t immediately respond to a request for comment.

So far there is little sign of improvement. Kumba Iron Ore Ltd$,$ the country$$s biggest producer of steel raw material, is running out of space to store ore it has mined and can$$t move to the port. Exxaro Resources Ltd$,$ a coal exporter, said last month Transnet$$s railings to the main export terminal are on course to fall for a sixth consecutive year.
