With effect from 23 October 2026, the South African Reserve Bank and the People's Bank of China have renewed their bilateral local-currency swap agreement, locking in a five-year deal worth up to CNY30 billion, or roughly ZAR74 billion. The two central banks are the only parties to this arrangement, and it allows them to exchange renminbi and rand directly, without routing through a third currency. That ceiling is a maximum facility, not proof that anyone has used the full amount.
SARB and PBoC have renewed their swap deal: a five-year, CNY30 billion facility — a ceiling, not a used amount.
The agreement aims to support trade between China and South Africa, encourage direct investment flows, and give both countries a tool to manage short-term balance-of-payments pressure. Interest on rand funds drawn under the deal will reference ZARONIA, South Africa's Rand Overnight Index Average, according to the renewal announcement. The facility is denominated in yuan and rand rather than US dollars, which is the detail drawing the most attention from currency watchers. Such arrangements echo how central banks elsewhere, including the Reserve Bank of Zimbabwe, use forex market interventions to steer currency stability and manage exchange-rate pressure.
This isn't a new idea. SARB and PBoC first signed a swap deal back in April 2015, valid for three years, with an initial ceiling of CNY30 billion then valued at about ZAR57 billion. That agreement had similar goals: supporting trade and investment, and cushioning balance-of-payments shocks. The 2026 announcement also references a separate 2013 deal that lets SARB invest in China's onshore bond market.
So what does this actually mean for markets? A swap line like this gives each central bank access to the other's currency on agreed terms. That creates a channel for local-currency liquidity in trade deals, reduces reliance on dollar settlement for eligible transactions, and offers a backstop if payment pressures emerge. South Africa's deputy finance minister has described this kind of arrangement as part of a broader push to diversify currency exposure, rather than a deliberate move away from the dollar.
It's worth noting what the announcement doesn't say. There's no mention of any drawdown or specific transaction using the renewed facility. A 2026 World Economic Forum report noted South Africa hadn't tapped the line at that point. Markets will likely watch whether trade flows start using yuan and rand more actively, and whether other African central banks pursue similar currency arrangements with Beijing.
