Despite repeated talk of economic recovery and transformation, Botswana remains firmly trapped in the grip of the diamond downturn.
The Bank of Botswana says weak global demand for diamonds, shifting consumer preferences and slow progress in economic diversification continue to weigh heavily on growth, exposing the country’s enduring dependence on its most important export.
In its April Monetary Policy Report, the central bank said overall economic performance remains weak, constrained by subdued global conditions, structural challenges in the diamond sector and sluggish transformation efforts.
Botswana’s economy contracted by 0.7 percent in 2025, following a 2.8 percent contraction in 2024, underscoring how the economy has struggled to regain momentum even as parts of the non-mining sector continue to expand. Mining GDP fell 14 percent last year, while diamond mining alone contracted 14.9 percent.
The central bank’s assessment offers a sobering reminder that Botswana’s diamond problem is no longer merely cyclical.
Global rough diamond prices fell 4.5 percent in the first quarter of 2026 as weak demand, excess inventories and persistent uncertainty continued to pressure the market. The report also flagged the growing threat from lab-grown diamonds, which now account for an estimated 20 to 25 percent of market share, particularly in lower-value segments.
The fallout is already showing in public finances.
Lower mineral revenues have forced the government to widen its budget deficit projections, while the central bank warns that continued diamond weakness could deepen fiscal pressures, strain foreign exchange reserves and complicate recovery efforts.
For all the rhetoric around diversification, the Bank’s message is unmistakable: Botswana remains dangerously exposed to a diamond industry undergoing structural change and time is running out to build a credible alternative.
