• Net official international reserves increased by US$315 million against a September programme floor of US$291 million
• ZiG monetary base growth was contained at ZiG2.17 billion against a ceiling of ZiG2.54 billion, with no new RBZ credit extended to the non financial public sector
• The September figures remain the RBZ’s provisional self assessment and will require IMF validation under the third programme review

Harare- The Reserve Bank of Zimbabwe says it has remained within all three monetary quantitative targets under the IMF Staff Monitored Programme at the end of September 2026, combining faster reserve accumulation with restrained ZiG liquidity growth and zero new central bank lending to the non financial public sector. The outturn extends a monetary discipline record already validated by the IMF through June and places reserve rebuilding at the centre of Zimbabwe’s attempt to establish a credible policy track record.

In its Q3 Monetary, Currency, Price and Financial Developments Snapshot, the RBZ said the change in net official international reserves reached a provisional US$315 million against a programme floor of US$291 million. Growth in the ZiG monetary base amounted to ZiG2.17 billion against a ceiling of ZiG2.54 billion, with changes in RBZ credit to the non financial public sector maintained at zero against a zero ceiling.

“The Reserve Bank successfully met all the Quantitative Targets and made significant progress on meeting the SMP structural benchmarks following the second SMP Review Mission in September 2026,” the central bank said.

The September performance means net official international reserves exceeded the programme floor by US$24 million, equivalent to an 8% buffer above the minimum required level. Monetary base growth came in roughly ZiG368 million below the programme ceiling, leaving the central bank with about 14% headroom against the agreed limit.

Those two movements address the principal monetary vulnerabilities the IMF programme was designed to constrain. Zimbabwe is accumulating external assets at the same time that growth in the domestic monetary base is being limited, reducing the scope for excess local currency liquidity to migrate into the foreign exchange market.

The third target deals directly with fiscal dominance. RBZ credit to the non financial public sector remained unchanged at zero through September, maintaining the programme prohibition against new central bank financing of government and other covered public entities.

That restraint is important in Zimbabwe because previous episodes of monetary instability were amplified by the creation of domestic liquidity to finance public expenditure. An SMP ceiling of zero creates a measurable boundary between fiscal requirements and central bank balance sheet expansion, forcing government expenditure to remain more closely aligned with revenue, approved borrowing and available cash resources.

The performance has strengthened progressively during the programme. At the end of March, the RBZ reported a US$107 million increase in net official international reserves against a US$74 million floor. By June, the increase had reached US$265 million against a US$195 million programme requirement, before rising to the provisional US$315 million by September.

Monetary base growth has remained below the respective ceilings across the same review dates. The RBZ reported growth of ZiG423 million against a March ceiling of ZiG602 million, ZiG1.30 billion against a June ceiling of ZiG2.02 billion and ZiG2.17 billion against the September limit of ZiG2.54 billion.

The reserve accumulation is occurring inside a considerably stronger external position. Total reserves covering the ZiG had risen to about US$1.96 billion by September, compared with approximately US$276 million in April 2024, giving the central bank a much larger asset buffer behind the domestic monetary system.

RBZ gold holdings have also risen from around 1.5 tonnes in April 2024 to approximately 4.9 tonnes by September 2026. Foreign currency inflows reached about US$15.9 billion during the first nine months of 2026, supported by stronger export receipts, remittances and successive trade surpluses during the third quarter.

Net official international reserves under the IMF programme should not be treated as the same measure as the headline US$1.96 billion reserve stock. The programme measure is based on liquid and readily available official reserve assets net of defined short term foreign currency liabilities, with the IMF applying specific valuation and programme rules to assets including monetary gold.

That distinction makes the US$315 million figure particularly useful. It measures the cumulative improvement against an agreed programme definition rather than simply recording the gross value of assets held by the central bank.

The IMF had already confirmed strong implementation through the end of June. Following its September review mission, Fund staff said all quantitative and indicative targets through June had been met except the indicative target covering protected social and priority expenditure, with the RBZ maintaining tight monetary conditions and rebuilding reserves. 

The September numbers extend that record from the RBZ side of the programme, though they remain provisional. The central bank described the figures as its own assessment of the Q3 targets, and the IMF’s programme timetable places the formal third review of the end September test date in the next review cycle. Zimbabwe therefore cannot yet treat the Q3 outcome as an independently confirmed IMF assessment.

That qualification is important because the SMP covers considerably more than monetary policy. It also contains fiscal targets, social spending commitments, public financial management reforms, foreign exchange reforms and governance benchmarks, meaning compliance by the RBZ with its three monetary quantitative targets does not establish that every September programme condition across government has been met.

The programme itself does not provide Zimbabwe with IMF financing. It is a 10 month monitoring arrangement designed to establish a verifiable record of policy implementation as the country pursues arrears clearance, debt restructuring and broader international financial re engagement.

That makes sustained compliance economically more consequential than any single quarterly number. Zimbabwe’s external debt and arrears position means future creditor engagement depends partly on demonstrating that monetary financing, uncontrolled liquidity growth and reserve depletion are being replaced by repeatable policy rules.

The September monetary results provide three measurable components of that record: no new RBZ financing to the covered public sector, monetary base growth below its ceiling and net international reserves above their required floor. Maintaining all three simultaneously reduces the risk that reserve gains are subsequently overwhelmed by domestic liquidity creation.

The stronger reserve buffer also gives the ZiG a different starting position heading into 2027. Reserve assets have expanded sharply, gold accumulation has accelerated and the formal economy is generating substantially more foreign currency than it was at the launch of the currency.

Preserving that position requires the monetary base to continue growing within the capacity created by reserves, economic activity and demand for the domestic currency. A sustained return to central bank financing of fiscal requirements would weaken that relationship and place renewed pressure on the foreign exchange market.

The end September figures therefore move Zimbabwe one review date further into the programme with the central bank still inside its monetary limits. IMF validation of the Q3 numbers, continued reserve accumulation and adherence to the wider fiscal and structural commitments will determine how much of that record can eventually be converted into progress on arrears clearance and debt restructuring.
