Zambia's Stock Rally: Is Copper the Main Character in the Market's Viral Sentiment?

The story of Zambia's market is a classic case of a single commodity driving a viral sentiment. The Lusaka Securities Exchange's benchmark index has been the world's second-best performer this year, soaring nearly 17% in dollar terms and ranking ahead of major peers. But the real story is the 56% surge from January to August 2025 that put it at the top of the global charts. This isn't just a local rally; it's a direct translation of copper's breakout into stock market gains.

The catalyst is clear and powerful. Record copper prices above $13,000 per ton have become the main character in Zambia's economic narrative. This isn't a minor tailwind. Copper accounts for nearly 60% of the country's current account receipts, making its price a direct lever on national finances and investor confidence. When copper rallies, Zambia's entire economic story shifts, and that story is now being priced into its stocks.

The market's performance dwarfs regional competition, proving the intensity of this capital flow. While Nigeria's market gained 40% and Johannesburg rose 25% over the same period, the LuSE's 56% surge shows a different dynamic at play. More broadly, the market's 12-month return of 72.3% is a staggering outperformance that highlights how deeply copper's momentum has been digested by the local market. This isn't a slow build; it's a rapid re-rating fueled by a single, trending commodity.

In essence, the market's viral sentiment is a mirror to copper's price action. Every spike in the metal's value above $13,000 pulls more attention and capital toward Zambian equities, making the copper rally the undeniable headline that everyone is watching.

Domestic Policy: The De-dollarization Headline

While copper prices provide the headline momentum, a series of domestic financial reforms has been the quiet engine behind the market's strength. These policies have directly reshaped investor sentiment, making equities a more compelling destination for capital.

The most immediate catalyst was a government directive to curb foreign currency use. By instructing market participants to settle all domestic transactions in the Zambian kwacha, authorities sparked a wave of dollar selling. This "panic selling" dramatically increased the supply of dollars in the market, pushing the local currency to a two-year high. A stronger kwacha reduces import costs and boosts the local purchasing power of export revenues, directly supporting the economy that underpins the stock market.

Government bond yields, which once soared to a peak of 34 percent, have fallen to around 20%. That 14-percentage-point drop is a powerful signal. It makes equities look far more attractive by comparison, as investors seek better returns in a market that is also seeing strong corporate results. The capital shift is real: funds are moving from bonds to equities, channeling more money into productive industries like energy and mining.

Technology has further fueled this engagement. The launch of a mobile trading app for retail investors has increased participation and market activity. This innovation lowers barriers to entry, allowing more Zambians to directly participate in the rally and adding a new layer of domestic demand for shares.

Together, these reforms paint a picture of economic renewal. The de-dollarization drive strengthens the local currency, the bond yield decline improves the relative value of stocks, and the mobile platform deepens retail involvement. As LuSE CEO Nicholas Kabaso noted, this is how you support the kwacha: by attracting foreign investors who bring dollars to buy shares. The domestic policy setup has created a virtuous cycle, making the stock market not just a beneficiary of copper, but a central pillar of the country's growth narrative.

Headline Risk: Political Uncertainty and IMF Decision

The rally's momentum now faces a critical test from political and policy uncertainty. The market's reliance on a stable anchor is being challenged by two converging risks: the end of the IMF program and the pressures of an election-year budget.

First, the government's decision to drop its plan for a one-year IMF extension introduces a major timing gap. After initially seeking a $145 million extension to bridge the gap, Zambia's finance ministry confirmed on January 8 that it will not pursue this option. Instead, it will immediately engage the Fund on a successor program after the final review this month. This about-turn creates a period of open-ended uncertainty. While the intent to stabilize is clear, the lack of a new framework on the table leaves markets to price in a "residual risk premium" for the interim. The IMF's role has been the crucial policy anchor; its absence, even temporarily, is headline risk.

This uncertainty lands squarely on an election year budget. The 2026 fiscal plan, presented in October, is a balancing act under the spotlight. It must manage a 2.1 per cent fiscal deficit target while funding critical social services and infrastructure. The difficult trade-offs are evident, with debt servicing consuming a considerable share of resources. The budget's challenge is to maintain discipline and growth momentum ahead of the August election, a task made harder by persistent inflation and power shortages.

The scale of the fiscal challenge is immense. The government faces a total projected domestic debt obligation of ZMW119.8 billion for 2026. This isn't just a number; it's a refinancing wall. The bulk of this, ZMW96.3 billion, is resident debt, testing domestic balance sheet capacity. A smaller but critical ZMW23.5 billion (about $1.18 billion) is non-resident debt, which directly impacts foreign exchange stability. These obligations trace back to high-yield borrowing during the post-default period, creating a maturity wall that must be managed without a new IMF program in place.

The bottom line is that the copper-driven rally has been a story of external strength and domestic reform. Now, the setup shifts. The market's viral sentiment is being tested by a policy vacuum and a heavy debt load. Until a successor IMF program is clear, and the budget's difficult choices are navigated, this residual risk premium will remain a shadow over the rally.

Catalysts and What to Watch

The market's viral sentiment is now a setup waiting for its next act. For the rally to continue, three near-term watchpoints must stay in focus: copper's price stability, policy clarity, and the breadth of capital inflows.

First, copper's price action remains the non-negotiable headline. The market's 17% rally this year is a direct translation of the metal's record highs above $13,000 per ton. Any sign of a reversal below that key level would immediately threaten the entire narrative. Investors must also monitor for production risks. The sector's growth story is tied to energy supply, and any new disruptions from the severe power shortage that has lingered since 2024 could pressure output and feed price volatility. The copper rally is the main character; its performance will dictate the market's script.

Second, the policy vacuum created by the dropped IMF extension must be filled. The government's decision to not pursue a one-year extension of its IMF program leaves a critical gap. The coming weeks, leading up to the IMF's final review, will be about clarity. The market needs to see a concrete plan for a successor program and, more importantly, a strategy for managing the ZMW119.8 billion domestic debt obligation due in 2026. Without this, the risk premium for policy uncertainty will remain elevated, capping the market's upside.

Finally, the strength of the rally must be broad-based. The launch of a mobile trading app for retail investors is a positive signal for participation, but the market's recent performance has been fueled by limited share supply and intense competition. The key metric to watch is trading volume and the turnover ratio. If the rally is driven by a few large players or speculative flows, it may lack durability. True, broad-based capital inflows would confirm that the shift from bonds to equities is structural, not temporary. This is the final piece of the puzzle: whether the market's momentum is a viral trend or a sustainable re-rating.

The bottom line is that the market's setup is now a balancing act. It relies on a stable copper price, a swift policy resolution, and deepening participation. Any stumble on these three fronts could quickly reverse the viral sentiment that has carried it to the top of the global charts.
