Zimbabwe's government owes platinum producers more than $228 million in unpaid export earnings accumulated under the country's foreign-currency retention system.
Exporters are required to convert 30 percent of their proceeds into local currency through government channels. Payments in local currency are frequently delayed, leaving mining companies without timely access to part of their export income.
Alex Mhembere, chair of the Platinum Producers' Association, said the arrears recorded as of May 2026 were worsening conditions for companies already dealing with high operating costs and unreliable electricity supply. He said repeated appeals for faster payment had produced little change.
The finance ministry has acknowledged the debt and attributed the delays to constraints on government revenue. Zimbabwe uses retained foreign currency to finance infrastructure projects, essential imports and repayments on external borrowing.
Individual producers have disclosed substantial unpaid balances. Valterra Platinum said it was owed $100 million from 2025 export proceeds generated by its Unki operations, while Impala Platinum said the amount due to its Zimplats business stood at $78 million.
Platinum producers owned by South African mining groups, including Sibanye Stillwater, generated a combined $1.8 billion in export revenue during 2025. Zimbabwe is the world's third-largest producer of platinum group metals after South Africa and Russia.
Platinum group metals are the country's second most valuable mineral export after gold and are widely used in catalytic converters that reduce vehicle emissions. Gold producers have also criticized the retention system, arguing that conversion into an overvalued local currency erodes the value of their export earnings.
