Moody's downgrades Botswana to Baa2 as diamond slump strains finances

Moody's lowered Botswana's domestic- and foreign-currency long-term issuer ratings to "Baa2" from "Baa1" on Friday, pointing to an expected worsening of the country's public finances. It is the second time in less than a year that the ratings agency has cut the sovereign, which now sits two notches above junk status.

The downgrade lands days after Finance Minister Ndaba Gaolathe said Botswana expects a significantly smaller budget deficit this fiscal year, aided by stronger-than-anticipated central bank revenue and spending restraint.

Botswana's economy, long held up as an African success story, has been battered by a protracted slump in the global diamond market, driven by economic uncertainty and the rising popularity of lab-grown stones. Diamonds generally generate roughly one-third of national revenue and three-quarters of foreign exchange earnings.

Moody's attributed the weaker fiscal position to softer diamond-sector revenue, lower-than-expected receipts from the Southern African Customs Union — a key source of government income — and disappointing proceeds from newly introduced tax measures.

The agency also cautioned that a further cut could follow if Botswana were to materially raise its investment in De Beers through debt-financed transactions, a sale Anglo American aims to complete in the final quarter of this year.

The outlook was shifted to stable from negative, reflecting a stronger fiscal policy response and the possibility that a more sustained recovery in diamond revenue could slow the pace of debt accumulation.
