• ZiG inflation fell to 3.2%, yet dollar pricing still dominates much of the economy
• Tight ZiG liquidity has helped contain the exchange rate and parallel market premium
• Reserve cover remains 1.7 months against the minimum three-month mono-currency requirement

Harare- Zimbabwe has accumulated its strongest period of monetary stability since the introduction of ZiG, yet the Reserve Bank’s own 50.1% mono currency readiness score exposes the distance between stabilising the domestic currency and building an economy capable of relying on it exclusively.

Annual ZiG inflation stood at 3.2% in July 2026 following seven consecutive months of single digit inflation. The interbank exchange rate averaged about ZiG25.93 per US dollar between January and July, while foreign currency reserves increased to US$1.7 billion.  These are material improvements from the instability that characterised the earlier phases of Zimbabwe’s currency reform, and they require a harder interpretation.

Zimbabwe has stabilised a currency that still occupies a minority position in large parts of the economy. The Reserve Bank itself reports that ZiG transactions only moved above 40% of RTGS transaction values during May and June. Its mono currency framework wants that proportion to rise toward 60%.

The stability therefore exists before full monetary depth has been achieved. That distinction changes how inflation, exchange rate stability and confidence should be assessed. The 3.2% annual ZiG inflation rate accurately measures price movements expressed in ZiG. Its wider economic meaning is constrained by the continued dominance of the US dollar across corporate revenues, savings, imports, property transactions and significant sections of household expenditure.

Many Zimbabwean companies generate the majority of their domestic revenue in foreign currency. Imports of fuel, machinery, fertiliser, chemicals, spare parts and industrial inputs are also ultimately priced in foreign currency. That means a substantial part of domestic price formation still originates in US dollars. ZiG frequently operates as the settlement layer applied to prices whose economic reference point remains the US dollar.

The resulting inflation stability is real within the local currency price system. It is weaker evidence that ZiG has become the economy’s principal unit of account. A deeper measurement of monetary stability therefore requires three variables to move together.

ZiG prices need to remain stable, US dollar prices inside Zimbabwe need to remain stable, and the share of economic activity genuinely priced, saved and contracted in ZiG needs to increase.

The first condition has improved considerably, but the third remains incomplete.

The same distinction applies to the exchange rate. The official ZiG rate has remained within a narrow range around ZiG25 to ZiG27 per US dollar. The Reserve Bank reports that the average parallel market premium narrowed to about 15% during the first half.  The narrowing is positive, but it cannot automatically be interpreted as a direct measure of confidence in the currency.

ZiG liquidity remains deliberately tight. Statutory reserve requirements are maintained at 30% for demand and call deposits and 15% for savings and term deposits. The RBZ continues absorbing liquidity through Non Negotiable Certificates of Deposit and the ZiG denominated Term Deposit Facility. Government revenue collections also remove liquidity from the market.

Reserve money has remained within targets agreed under the IMF Staff Monitored Programme. ZiG reserve money stood at ZiG6.60 billion in the second quarter against an SMP ceiling of ZiG7.33 billion.  That discipline has been effective in preventing excess local currency from chasing the US dollar. It also means part of the exchange rate outcome is being generated through scarcity.

A currency can appreciate or maintain a narrow premium because households and firms want to hold it, and it can also remain stable because there is insufficient currency available to create substantial foreign exchange demand. Those are economically different outcomes.

The stronger version of ZiG stability would emerge when the amount of local currency in circulation increases alongside economic activity and the parallel premium remains contained because holders voluntarily retain ZiG rather than immediately converting it into dollars. Zimbabwe has not yet fully demonstrated that condition.

The credibility of ZiG also depends on how Government settles its obligations. The public sector is one of the largest creators of local currency demand and liquidity. Taxes paid in ZiG create compulsory demand for the currency. Government procurement and supplier payments then redistribute that liquidity into the private economy. Where contractors, exporters and suppliers experience delays in receiving payments, the amount of ZiG entering circulation can remain unusually constrained.

That helps monetary control, and also creates working capital pressure for companies waiting to be paid. The authorities therefore have to distinguish between sustainable monetary discipline and stability produced partly through delayed circulation of obligations. A functioning mono currency system eventually requires Government to pay legitimate obligations on time without destabilising the exchange rate. That is a substantially harder standard than maintaining exchange rate stability while local liquidity remains thin.

ZiG still needs to become a store of value. Transaction usage is only one part of currency confidence. Savings matter more. A durable currency needs households and companies to willingly retain it beyond immediate tax, payroll and transactional requirements.

The RBZ has introduced several mechanisms to encourage that behaviour. ZiG savings deposits carry a minimum rate of 5%, while time deposits carry 7.5%. The new ZiG Term Deposit Facility provides 30, 60 and 90 day instruments and is intended to establish a local currency yield curve. The instruments are an important development.

The next evidence needs to come from behaviour. ZiG term deposits should expand, deposit maturities should lengthen, while the share of household and corporate savings retained in local currency should rise. Repeated conversion into US dollars after receipt would show that ZiG is functioning primarily as a transactional currency while the dollar retains the store of value role. That distinction remains central to any credible mono currency transition.

Meanwhile, low inflation has not yet achieved cheap capital. Zimbabwe’s interest rate structure exposes another gap between monetary stability and economic transmission. The policy rate has been reduced from 35% to 30%, while the Targeted Finance Facility rate available to banks has been reduced from 20% to 15%, with productive sector lending capped at 25%.

Annual ZiG inflation is 3.2%, the policy rate therefore remains 26.8 percentage points above annual inflation. The RBZ itself acknowledges that some banks have failed to adjust lending rates sufficiently and that prevailing rates are pricing productive sectors out of formal credit. It has made a similar observation regarding US dollar loans after international benchmark rates declined.

This matters because monetary stability should eventually reduce the cost of financing productive investment, as manufacturers need machinery, farmers need irrigation equipment, mining companies need development capital, and retailers and processors need working capital.

A stable currency produces limited economic value where companies still cannot borrow economically. The next phase therefore requires interest rate transmission. Banks need to convert lower inflation and improving macroeconomic predictability into lower lending rates. Otherwise, monetary stability will coexist with a private sector unable to finance the investment needed to deepen economic growth.

On the other hand, Zimbabwe’s foreign currency reserve position has strengthened significantly. Reserves reached US$1.7 billion at the end of July, covering approximately 1.7 months of imports. The RBZ’s own mono currency framework requires at least three months of import cover, with a longer term objective reaching six months. The Bank expects reserves to rise to between 1.8 and two months by year end.

Even the upper end of that forecast remains materially below the minimum transition threshold. The gap is particularly important because reserve accumulation is occurring during an unusually favourable mineral price cycle. Foreign currency receipts increased 47.8% to US$10.72 billion during the first half of 2026. The current account surplus rose to an estimated US$1.3 billion from US$248 million a year earlier, supported by higher export receipts, remittances and strong prices for gold and PGMs.  Zimbabwe therefore needs to accumulate reserves aggressively while the commodity environment is supportive.

The quality of reserve accumulation matters alongside the headline value. RBZ gold holdings increased from 4,382kg in March to 4,525kg in June. The physical increase is considerably smaller than the increase in foreign currency inflows across the economy.  Zimbabwe is also benefiting from exceptionally strong international gold prices. That raises an important vulnerability because a reserve position built during a period of elevated commodity prices can strengthen quickly without an equivalent increase in physical export volumes.

The reverse can occur when prices correct. If gold prices normalise while production remains comparatively unchanged, the pace of reserve accumulation will weaken. That makes production growth and economic diversification increasingly important. The reserve architecture cannot depend predominantly on high gold prices continuing indefinitely.

Zimbabwe needs more mineral tonnes, like it also needs more foreign currency from manufacturing, agriculture, tourism, services and other export sectors as the external position faces another threat from weather.

The RBZ has incorporated the expected 2026 and 2027 El Niño into its monetary risk framework.  A severe rainfall shock would reach monetary stability through several channels. Agricultural production could weaken, leading to food import requirements to increase, agricultural exports to decline, hydropower generation could deteriorate, while electricity imports could rise.

Higher food and electricity imports would place additional pressure on foreign currency reserves at precisely the time export earnings from agriculture weaken. Zimbabwe therefore needs to use the current period of strong mineral receipts to reduce future exposure through irrigation development acceleration, water storage and conveyance infrastructure need investment, just like power generation needs diversification away from excessive hydrological dependence, and agricultural production has to become less sensitive to seasonal rainfall.

These are monetary policy issues because they determine future import demand, reserve utilisation and inflation. The current external position is increasingly supported by mining. Gold and PGMs are driving export receipts and the current account surplus, and that provides valuable foreign currency.

However, it also creates concentration, as mono currency architecture requires a diversified and recurring supply of foreign currency capable of meeting imports through different commodity cycles, hence, manufacturing exports need to grow, tourism needs to deepen, horticulture needs to expand, and regional service exports need to become material.

Mining itself needs greater downstream processing so that more value is retained from each tonne exported. The more diversified the foreign currency base becomes, the less vulnerable reserves are to a correction in one mineral price.

Broad money growth adds another future pressure. Total broad money increased 31.4% from December 2025 to June 2026 and was 45.9% higher year on year. The local currency component increased 62.5%, while inflation has remained subdued because reserve money growth has been controlled and excess liquidity has been sterilised.

That framework will eventually face a larger challenge. The economy cannot remain permanently starved of local currency if ZiG is expected to become the dominant medium of exchange. More ZiG has to enter circulation as the economy grows. The deeper credibility test will therefore come when local liquidity expands and inflation remains low. Current stability demonstrates that the RBZ can control scarcity, but the next phase has to demonstrate that it can manage abundance.

Demand for ZiG has also to become organic. RBZ wants ZiG transaction usage to rise from around 40% toward 60%. Government is supporting that objective through tax requirements, public sector payments and a lower IMTT rate of 1.5% on ZiG transactions compared with 2% for US dollar transactions. Those measures create demand, and the longer term requirement is voluntary demand.

Companies should choose ZiG because pricing is predictable, households should hold it because savings retain purchasing power, banks should lend it because long term funding exists, and suppliers should accept it without immediately applying a parallel market hedge.

A currency whose use depends principally on taxes, regulations and scarcity has not yet reached the same level of credibility as one willingly held across savings, credit and commercial contracts.

Therefore, the RBZ’s 50.1% readiness score is therefore useful. Zimbabwe has made major progress on inflation, exchange rate management, banking sector stability and fiscal monetary coordination. The weaker areas are also clear as discussed in the article.

Reserve cover is 1.7 months, ZiG transaction depth remains below the desired level, formal credit is still expensive, and dollar preference remains strong.

The foreign exchange market still depends materially on central bank intervention. The electronic interbank platform planned for the fourth quarter can improve price discovery and allow commercial banks to trade foreign exchange more directly.  That reform should become one of the more important indicators of progress. A genuine market should be capable of absorbing changes in ZiG liquidity without repeatedly requiring the central bank to establish the clearing price.

Hence, Zimbabwe can credibly claim that ZiG has become substantially more stable as inflation has fallen, the official exchange rate has stabilised, the parallel premium has narrowed, with reserves increasing and reserve money has remained controlled, while the banking system remains well capitalised with a 24.13% capital adequacy ratio and non performing loans at 3.19%.

The harder claim would be that Zimbabwe has already created the conditions for a durable mono currency economy. That requires more evidence as reserve cover has to move above three months, credit costs have to fall, ZiG needs to become a store of value, while local currency transactions need to become dominant without coercive scarcity.

Government needs to settle obligations consistently without destabilising liquidity, while reserve accumulation needs to rely increasingly on production and diversified exports instead of favourable commodity prices. The currency then has to survive the next large external shock, including El Niño, weaker gold prices or an energy shock, without a return to monetary instability.

Zimbabwe has demonstrated that it can stabilise a scarce ZiG inside a dollar dominated economy, it has to demonstrate that ZiG remains stable when there is enough of it in circulation for the economy to genuinely use it.
