• Zimbabwe's inflation is expected to rise in March, April, and May 2026 due to fuel price increases, before stabilising from June
  
• The RBZ's Monetary Policy Committee maintained a 35% policy rate, citing inflation concerns and a stay-the-course monetary policy stance
  
• The fuel price shock is driven by external factors, including the Middle East conflict, and Zimbabwe's domestic levy structure

Harare- Zimbabwe's Monetary Policy Committee has flagged that monthly inflation will increase slightly in March, April, and May 2026, before returning to steady-state levels from June 2026 according th the latest MPC statement. The annual ZiG inflation rate will experience a slight level shift as a result.

For a country that only just achieved single-digit annual inflation for the first time in over three decades, a MPC-confirmed inflationary episode in the next three months is not a minor footnote. It is the first material test of whether Zimbabwe's inflation management achievement is durable or fragile, structural or situational.

The driver of the expected inflation increase is unambiguous. ZERA raised fuel prices twice in March 2026 alone, pushing diesel to US$2.05 per litre and petrol blend to US$2.17 per litre, with the combined impact of the Middle East oil price shock and Zimbabwe's domestic levy structure producing increases of 15.8% on diesel and 26.9% on petrol in a single month.

Fuel is not merely one item in Zimbabwe's consumer price index. It is an input cost that runs through virtually every sector of the economy simultaneously. Transport costs rise immediately when fuel prices rise, because every vehicle, every bus, every truck, every generator that runs on diesel or petrol passes the increased fuel cost through to the prices of the goods and services it enables.

Food prices follow, because food is grown with fuel-intensive equipment, processed with fuel-powered machinery, and distributed through a logistics network that prices its services on diesel. Industrial production costs rise because the unreliable electricity grid forces manufacturers to run diesel generators as primary or backup power. Service sector prices follow as businesses adjust their pricing to recover higher energy and transport input costs.

The MPC's acknowledgement that fuel price increases will have second-round inflationary effects through adverse inflation expectations is an honest assessment of the transmission mechanism that connects ZERA's pump price announcement directly to the prices of goods and services across the economy.

The MPC's projection that monthly inflation will increase in March, April, and May before stabilising from June deserves to be read carefully rather than accepted at face value. The projection assumes that the fuel price shock is temporary and that Brent crude stabilises or retreats from its current levels above US$100 per barrel as the Middle East situation evolves. That assumption may prove correct, and there are historical precedents for geopolitical oil price spikes reversing within a quarter.

But it may also prove optimistic if the disruption to Strait of Hormuz shipping routes proves more prolonged than current market pricing anticipates, or if the conflict escalates further. The IEA's Executive Director has confirmed that over 40 energy assets across nine countries have been severely damaged, and the return of full production capacity from those assets will take time regardless of when hostilities cease. Zimbabwe's fuel price path over the next three months is therefore not purely within the RBZ's analytical control, because it depends on external variables that are genuinely uncertain.

The second-round effect concern is analytically more important than the first-round fuel price impact. First-round effects are mechanical: fuel prices rise, and the CPI basket reflects that rise directly. They are large in Zimbabwe because fuel carries a heavy weight in household budgets and business input costs, but they are also temporary if the fuel price itself stabilises.

Second-round effects are structural, fuel price increases raise inflation expectations among households, workers, and businesses, who then incorporate those elevated expectations into wage demands, price-setting behaviour, and contract negotiations. Once inflation expectations shift upward, reversing them requires sustained evidence of price stability over an extended period, which is why central banks treat expectation management as one of their most critical functions.

Zimbabwe's inflation expectations had been on a genuinely encouraging trajectory: the country had achieved three decades' worth of disinflation in a short period, and consumers and businesses were beginning to plan around single-digit inflation for the first time in living memory for many Zimbabweans. A three-month inflation uptick driven by fuel prices is manageable if it is clearly communicated and clearly bounded. It becomes a more serious problem if it triggers a broader repricing across the economy that embeds higher inflation expectations into the system before June's stabilisation arrives.

The interest rate stance of 35% provides the monetary policy anchor that constrains how far inflation expectations can drift. At 35%, ZiG borrowing costs are high enouh that credit-driven demand inflation is not a meaningful risk in the current cycle. The inflation Zimbabwe is facing in the next three months is cost-push, driven by external supply shocks, not demand-pull driven by excessive domestic credit creation. Raising rates further in response to a supply-side shock would increase the cost of credit without addressing the supply-side cause, while further suppressing the economic activity that generates the tax revenue and foreign currency earnings that support ZiG stability.

The MPC's hold decision is therefore analytically correct for the current shock type. The risk of holding at 35% in a cost-push inflation environment is not that it fails to contain inflation but that it reinforces the liquidity constraint on ZiG that is already limiting the currency's adoption in the formal economy. A currency with a 35% borrowing rate and a 3.85% inflation rate has a real interest rate of over 31%, which is among the highest in the world.

That is an exceptionally tight monetary stance, and its continued application through a temporary supply-side inflation episode extends the period over which ZiG credit remains inaccessibly expensive for productive businesses.

For households and businesses planning through the next quarter, the MPC's guidance translates to a clear and specific outlook. March 2026 prices will be higher than February's across fuel-sensitive categories: transport fares, basic foodstuffs, manufactured goods with significant fuel input costs, and services with energy-intensive delivery requirements. April and May will carry the full impact of the fuel price increase as it works through the supply chain.

From June, the trajectory should reverse toward the steady-state levels that the disinflation of the past year has established, assuming the external oil price environment cooperates. The businesses that will navigate this period most effectively are those that communicate clearly with customers about the temporary nature of price adjustments, avoid embedding the fuel shock into permanent cost structures, and retain sufficient working capital flexibility to absorb the input cost increase without triggering a cycle of price increases that outlasts the original shock.

The businesses that will struggle are those operating on thin margins with limited pricing power and significant fuel input costs, which in Zimbabwe's economy means transport operators, small manufacturers, and food processors in the informal sector. For those businesses, the MPC's projection of a June return to normal is not a comfort. It is three months of margin compression that many of them will not survive at current fuel prices.
