(Bloomberg) -- African central banks are stepping up uncoordinated interventions in their markets to prop up their slumping currencies and dampen imported inflation.
South Sudan, Mauritius, Nigeria, Zambia and Zimbabwe have together spent at least $1.3 billion since July to defend their currencies, according to data compiled by Bloomberg. Ethiopia, an outlier, on Wednesday sold dollars to close the gap between the official and parallel market rate, days after it allowed its currency to float freely.
While central banks routinely intervene in currency markets in Africa, those “interventions become more frequent and at a higher value when you have a terms-of-trade shock,” according to Benedict Craven, the principal economist at the Economist Intelligence Unit.
Factors influencing the size and scope of interventions may include “higher import prices or lower export prices, capital flight, or because inflation is very high and the central bank wants to use the exchange-rate to stabilize the price level,” Craven said.
Last month, Mauritius spent a $150 million to bolster the rupee after it plunged to a record low. The move appears to have helped stabilize the currency. Governor Harvesh Seegolam has assured markets that the bank is ready to intervene and that there’s no shortage of fire power to do so. The bank injected $20 million this week.

Zimbabwe’s central bank also stepped in to support its new currency, the ZiG, short for Zimbabwe Gold, after weakening against the greenback last month in part due to a build-up in demand for foreign currency at banks. It pumped $50 million into the market.
Given the multi-currency regime which the southern African nation operates in, the Reserve Bank of Zimbabwe will intervene, according to Persistence Gwanyanya, a member of the central bank’s monetary policy committee.
“If we have forex demand that can’t be met by voluntary liquidations, the central bank must step in. It has the reserves,” Gwanyanya said Tuesday by phone. The interventions in the interbank market will be “a permanent feature,” he added. “This is the trajectory of where we are going.”
The Bank of South Sudan intervened last week to stabilize its currency, which has lost about a third of its value against the greenback this year because of declining oil revenues, its main foreign-exchange earner. “We have injected something above $8 million” and plan to ensure the intervention is “sustained,” Governor James Alic Garang said.
Buying Time
Nigeria, whose naira is the world’s third-worst performing currency after the Lebanese pound and Ethiopian birr this year in part due to the central bank ending years of foreign exchange controls in June 2023, has picked up the pace of interventions in recent weeks.
The Central Bank of Nigeria realizes that after years of market dysfunction, “unless it’s playing some role in providing dollar liquidity, it doesn’t have a functioning foreign-exchange market,” said Razia Khan, chief economist for Africa and the Middle East at Standard Chartered Bank. “So the CBN has been both buying and selling foreign-exchange.”
The central bank recently sold $148 million to 29 lenders. On Wednesday it auctioned $876.3 million to 26 banks at a cut off rate of 1,495 naira per dollar to ease pressure on the local currency and promote price discovery.
Still, such interventions are simply buying time as authorities wait for market fundamentals to swing favorably in their way, said David Omojomolo, Africa economist at Capital Economics.
African central banks don’t have the fire power in terms of foreign-exchange reserves that their global peers such as the Bank of Japan have to support their currencies for longer periods of time, said Mark Bohlund, senior credit research analyst at REDD Intelligence. In July, Japan spent ¥5.5 trillion ($36.6 billion) in defense of its currency.
As such they should rather look at more long term solutions to solving their currency issues, said Omojomolo. “Improving the export capacity of your economy to generate dollar liquidity and more so attracting foreign investment remain the real way to work toward currency stability,” he said.
