Thandi Mthembu's artisanal leather goods workshop in Braamfontein has thrived for seven years, but the past month has tested her resolve like never before. With mounting tensions between the U.S. and Iran threatening shipping lanes through the Strait of Hormuz, her import costs for Italian chrome tanning chemicals have spiked 23 percent since May. At the same time, the rand has weakened against the dollar, adding another layer of pressure to her already razor-thin margins.
"I'm not alone in this," says Mthembu, speaking to the broader reality facing Johannesburg's small business ecosystem. The city's entrepreneurs—from manufacturing hubs in Wadeville to tech startups in Sandton—are learning an uncomfortable lesson: global geopolitics is no longer a distant news story. It's a direct tax on their bottom line.
The ripple effects are visible across multiple sectors. Johannesburg Chamber of Commerce data shows that 64 percent of local exporters have adjusted their logistics strategies in the past three months, with many absorbing costs rather than passing them to customers who are themselves squeezed by inflation. For businesses relying on Venezuelan aluminium supplies or Pakistani-sourced textiles, recent regional conflicts have simply cut off access—forcing costly pivots to alternatives.
Currency volatility compounds the challenge. The rand's fluctuation against major currencies means that a business quoting prices to European clients one month may face margin erosion the next. At the same time, rising geopolitical risk premiums have made bank financing more expensive for small enterprises lacking institutional backing.
Yet some entrepreneurs are adapting faster than others. A growing number are localizing their supply chains, partnering with producers in Gauteng and KwaZulu-Natal rather than relying solely on imports. Johannesburg's manufacturing sector—concentrated in areas like Isando and Benoni—is seeing renewed interest from businesses seeking to shorten supply routes and reduce exposure to global shocks.
What's clear is that the old playbook no longer applies. Small business owners attending networking sessions at venues like the JSE precinct are increasingly thinking like geopolitical analysts, monitoring news cycles alongside balance sheets. The question is whether local support infrastructure—from business mentorship programmes to government trade initiatives—can keep pace with these rapidly shifting realities.
For entrepreneurs like Mthembu, resilience now means staying informed, diversifying ruthlessly, and banking on the ingenuity that has always defined Johannesburg's business culture.
