African economies experienced a mixed inflation trend in August, with more than half recording declines, but rising oil prices above $100 per barrel threaten to undermine progress, according to data analyzed by BusinessDay Nigeria. The findings highlight a broadening disinflationary trend across the continent, yet the resurgence of global energy costs poses a critical challenge to monetary policymakers and households alike.
The August data revealed that nine of 16 tracked economies saw annual inflation fall compared to July, a slight improvement from the eight economies that recorded declines in the prior month. Mozambique, Côte d’Ivoire, and Angola led the reductions, while Nigeria, Egypt, Zambia, Zimbabwe, Ethiopia, and Botswana also reported lower inflation. However, the decline occurred before Brent crude prices surged past $100 per barrel in early September, raising concerns about renewed inflationary pressures.
Mozambique recorded the sharpest drop, with annual inflation falling to 6.45% in August from 7.48% in July. This improvement was driven by a significant decline in food and non-alcoholic beverages inflation, which eased to 8.91% from 12.62%. Similar moderation was observed in clothing, footwear, and miscellaneous goods, signaling broader price stability in key consumer categories.
Côte d’Ivoire saw its inflation rate drop to 1.2% in August, the lowest among the 16 economies, while Angola extended its disinflation trend, reducing annual inflation to 8.78% from 9.33%. The Angolan central bank responded by cutting its key interest rate by 100 basis points to 14.75%, marking its third consecutive rate reduction. This move followed improved domestic supply conditions and relative stability in the kwanza currency.
Nigeria’s inflation declined marginally to 15.39% in August from 15.43%, but the Central Bank of Nigeria (CBN) cut its benchmark rate by 350 basis points to 23% in September—the largest reduction since 2007. Despite this, rising global oil prices have already begun to impact domestic fuel costs, with petrol prices reaching N1,400 per litre in Lagos and Abuja, and diesel exceeding N2,000 per litre. These increases risk offsetting recent disinflationary gains.
Egypt’s inflation eased to 14.5% in August from 14.9%, with food and beverage inflation dropping to 6.3% and transport costs declining slightly. However, the Central Bank of Egypt maintained its key rate at 19% in August, citing ongoing geopolitical pressures on the Egyptian pound and fuel import costs. Ethiopia’s inflation fell to 15.1% from 15.3%, marking its first decline in five months, though it remained among the continent’s highest inflation rates.
Southern African economies showed mixed results. Botswana’s inflation declined to 9.3% from 9.4%, while Zimbabwe’s fell to 2.9% from 3.2% and Zambia’s to 6.2% from 6.5%. South Africa, however, recorded a modest increase, with inflation rising to 4.4% from 4.3%. The South African Reserve Bank raised its repo rate by 25 basis points to 7.25% on September 23, citing transport and housing inflation as key concerns.
In East Africa, Kenya, Uganda, and Tanzania saw inflation rise. Kenya’s inflation increased to 6.6% from 6.5%, remaining above its central bank’s target range for a fifth consecutive month. Uganda’s inflation rose to 4.1% from 4%, and Tanzania’s to 4.3% from 4.2%. Transportation costs were a primary driver in all three countries, exacerbated by global oil price volatility.
Ghana and Mauritius also faced renewed inflationary pressures. Ghana’s inflation climbed to 5% from 4.6%, with non-food inflation accelerating to 6.8% due to higher transport and utility costs. Mauritius saw its inflation rise to 4.9% from 4.4%, driven by increases in transportation and food prices. Tunisia’s inflation also increased to 5.4% from 5.1%, primarily due to food and non-alcoholic beverages.
The resurgence of Brent crude prices above $100 per barrel has intensified concerns about energy market instability. Escalating Middle East tensions have heightened fears of supply disruptions, potentially increasing fuel, transport, and electricity costs across Africa. For oil-importing economies, this could weaken currencies and drive up domestic prices, while oil exporters like Nigeria and Angola may benefit from higher export revenues but still face domestic fuel price pressures.
Nigeria’s situation exemplifies this dual challenge. While higher crude prices could boost oil revenues, domestic fuel prices have surged, increasing logistics costs and threatening to reverse recent disinflationary progress. Similar patterns were observed in Ghana and Kenya, where rising oil prices directly impacted transport and utility expenses.
The August data underscores the uneven nature of Africa’s disinflationary progress. While nine economies saw annual inflation declines, seven—including Ghana, Mauritius, Tunisia, Kenya, Uganda, Tanzania, and South Africa—experienced increases. This divergence highlights the continent’s complex economic landscape, where regional disparities and external shocks continue to shape inflation outcomes.
Central banks now face a critical decision: whether to maintain accommodative policies or tighten monetary conditions in response to energy price shocks. For economies with sustained disinflation, rate cuts may remain viable, but those experiencing accelerating fuel and food costs may need to keep rates elevated. The September inflation data will be pivotal in determining the next phase of monetary policy across the continent.
The public-interest implications of these trends are profound. Rising fuel and transport costs disproportionately affect low-income households, increasing the cost of essential goods and services. Businesses, particularly in logistics and agriculture, also face heightened operational expenses, which could dampen economic growth and investment.
As Africa enters the final months of the year, the disinflation gains achieved in August face a fresh test. The interplay between global energy markets, domestic monetary policies, and structural economic challenges will determine whether the continent’s progress is sustained or reversed. For now, the focus remains on how central banks navigate this volatile landscape to balance price stability and economic growth.
The data underscores the fragility of Africa’s disinflationary momentum. While more than half of the tracked economies have seen price pressures ease, the resurgence of oil prices above $100 per barrel introduces new uncertainties. Policymakers must act decisively to mitigate risks while supporting long-term economic resilience.
The findings highlight the need for coordinated efforts between central banks, governments, and international partners to address inflationary pressures. As the continent grapples with these challenges, the coming months will be critical in shaping the trajectory of economic stability and growth across Africa.
