Global credit ratingagency S&P Global Ratings has downgraded Botswana’s long-term foreign and local currency sovereign creditratings from BBB to BBB-, citing prolonged structural weakness in theglobal diamond market.
The agency also reducedthe country’s short-term sovereign credit ratings to A-3 from A-2, whilemaintaining a negative outlook, signaling potential further pressure onthe nation’s economy if diamond demand does not recover.
The downgrade reflectsconcerns about Botswana’s heavy economic reliance on diamond mining, a sectorthat has historically played a central role in the country’s export revenue andgovernment finances.
Botswana is widely recognizedas one of the world’s leading producers of natural diamonds. The diamond sectorhas traditionally accounted for:
· Around 70% of thecountry’s exports
· Nearly one-third ofgovernment revenue
However, structuralshifts in the global luxury market are placing increasing pressure on naturaldiamond demand.
Key factors affectingthe industry include:
· Rising popularity of lab-growndiamonds
· Slower luxury spendingin global markets
· Weak demand from China
· Tariff pressures andeconomic uncertainty
· Growing consumerinterest in gold jewellery
According to analysts,these trends are likely to continue influencing the diamond sector in thecoming years.
Synthetic or lab-growndiamonds have expanded rapidly in recent years. Industry estimates suggest thatlab-grown stones now represent:
· About 20% of theglobal diamond market by value
· Up to 50% of theengagement ring market in the United States
This rapid growth hascreated new competition for traditional natural diamond producers, particularlyin the bridal jewellery segment.
The shift has hadsignificant implications for countries like Botswana, where the economy isclosely tied to natural diamond production.
The downturn indiamond demand has also affected mining operations in Botswana.
The country’s primarymining company, Debswana, a joint venture between the Botswana government and De Beers, hasadjusted its production strategy in response to weaker market conditions.
Recent developmentsinclude:
· Reduced output atseveral mines
· Temporary closures atsome operations
· Production adjustmentsto stabilize supply
Diamond productiondropped significantly over the past two years:
· 2024: Productionfell 27% to 17.9 million carats
· 2025: Outputdeclined further to 15.1 million carats
Debswana expects tomaintain production at approximately 15 million carats in 2026,representing roughly 40% lower output compared with 2023 levels.
Only modest increasesare anticipated in 2027 and 2028 as market conditions graduallystabilize.
According toprojections from S&P Global Ratings, Botswana’s economic growth willremain relatively slow in the near term.
The agency forecasts:
· 2.8% economiccontraction in 2024
· 0.4% contraction in2025
· 2.5% economic growthin 2026
Government financesare also expected to remain under pressure. Botswana’s fiscal deficit isprojected to reach approximately 8.9% of GDP in the 2026/27 fiscal year,only slightly improving from 9.3% in the previous year.
Without significantpolicy changes or a strong rebound in global diamond demand, fiscal pressurescould continue through the end of the decade.
Despite the currentchallenges, industry experts note that natural diamonds continue to play animportant role in the global luxury jewellery sector. Major mining companies,including De Beers, remain key participants in the international diamondsupply chain.
However, changingconsumer preferences, evolving jewellery trends, and increased competition fromlab-grown diamonds are reshaping the market landscape.
For Botswana,diversifying the economy while stabilizing the diamond sector may become anincreasingly important priority in the coming years.
