In the heart of Johannesburg, where the Witwatersrand goldfields once ignited a global rush that transformed Africa’s economy, the Johannesburg Stock Exchange (JSE) remains a monument to the continent’s mineral wealth.
As of late 2025, the FTSE/JSE Resources 20 Index, the benchmark for South Africa’s mining heavyweights, has surged more than 76% year-on-year, outpacing global indices and propelling the JSE All Share Index to record highs.
Resource stocks are dominating, with titans like Anglo American and Sibanye-Stillwater driving valuations to new peaks amid soaring commodity prices.
But how did a once-dusty gold trading tent from 1887 become the world’s premier venue for gold, platinum, and diamond listings? And why, 138 years later, do these “picks and shovels” still rule the market?
From Gold Rush to Global Powerhouse
The JSE’s origins trace back to 1886, when gold discoveries on the Witwatersrand triggered South Africa’s first great boom. Within a year, prospectors, brokers, and financiers converged on a developing Johannesburg, trading shares in makeshift tents beneath acacia trees.
On November 8, 1887, the Johannesburg Stock Exchange was officially founded to organise the chaos. Its first listings were gold mining shares, and by the early 20th century, it had already evolved from a frontier bazaar into a global commodities exchange.
By 1899, the JSE listed over 69 gold companies, and by 1934, those listings had drawn £200 million in foreign capital, which was an incredible sum for the time.
The exchange became synonymous with mining speculation, funding the development of what would become the richest gold reef on earth.
The Rise of the Mining Majors
The 20th century cemented the JSE’s role as an incubator for industrial titans.
- Anglo American, founded in 1917 by Ernest Oppenheimer, became the beating heart of South Africa’s mining empire. With early capital from British and American financiers, Anglo consolidated gold and diamond interests, eventually acquiring De Beers in 1926, securing a near-monopoly in diamonds for decades.
- Sibanye-Stillwater, spun out from Gold Fields in 2013, emerged as a new-generation giant, dominating platinum group metals (PGMs) while maintaining strong gold assets.
As of November 2025, Anglo’s JSE market cap stands at R699 billion ($39 billion), while Sibanye’s has soared 165% year-to-date to R138 billion. Even amid volatility, these companies anchor the JSE’s global influence.
What Made the JSE a Magnet for Global Miners?
Several factors forged the JSE’s dominance:
- Unrivalled Mineral Endowment: South Africa holds 40% of the world’s platinum and 80% of PGMs and was once the top gold producer globally.
- Liquidity and Local Capital Depth: Pension funds, sovereign investors, and asset managers sustain one of the most liquid mining markets outside London and Toronto.
- Regulatory Reforms: Post-apartheid liberalisation and digital integration (adopting the LSE’s SETS system in 2002) made the JSE globally accessible.
- Ecosystem Effects: From Anglo to Impala Platinum, flagship listings attract smaller explorers and service firms, reinforcing Johannesburg’s mining-finance cluster.
By the 2000s, the JSE ranked among the world’s top 20 exchanges, with mining comprising over half of total market capitalisation, a ratio still unmatched today.
2025: A Resource Rally Reignited
This year, the resource boom returned with force. The Resources 20 Index jumped nearly 18% in January alone, doubling by Q3 to reach 106,315 points by late October.
- Gold surged past $2,700/oz amid global inflation fears.
- PGMs rebounded on renewed automotive demand.
- The index’s 44% dollar gain eclipsed the MSCI Emerging Markets’ 23% rise.
Anglo’s interim EBITDA hit $3 billion, driven by copper and iron ore, while Sibanye’s gold surge confirmed investor appetite for precious metals.

Why Resource Stocks Still Rule
Despite diversification into tech and finance, mining remains the JSE’s lifeblood. The sector contributes only 8% to South Africa’s GDP but accounts for 30–40% of the All Share Index’s value.
High commodity prices, easing power constraints, and global demand for critical metals (PGMs for EVs and copper for grids) keep the sector growing. The JSE’s structure that’s anchored by resource-linked liquidity and investor familiarity ensures mining’s dominance persists.
Yet the risks are familiar: cyclical commodity prices, regulatory uncertainty, and geopolitical tremors (like Botswana’s De Beers negotiations).
Still, with total JSE market capitalisation surpassing R23 trillion, mining’s heartbeat remains strong.
The Bottom Line: From Ore to Opportunity
The JSE’s rise from a gold rush trading post to a global mining hub mirrors South Africa’s evolution from boomtown to diversified powerhouse.
In 2025, as the world races toward renewable energy and critical mineral security, the JSE’s resource roots are a strategic advantage.
For investors eyeing 2026, the message is clear: bet on the mines, but diversify the basket.
