The Zimbabwean dollar was a fiat currency, meaning that instead of its value being backed by a physical commodity with inherent value, such as gold, it instead derived its value from government authority and public trust (Modern Treasury, n.d.). Fiat money is the most prevalent form of currency in modern economies, which is largely due to its great flexibility. Since it is not derived from a physical commodity, fiat money is seen as a more stable option (Modern Treasury, n.d.). As Modern Treasury explains, “the control of fiat by central banks helps support a stable economy, because banks can better manage economic variables such as interest rates and credit supply.” (Modern Treasury, n.d. ). This level of control over money allows central banks to respond to shocks, smooth business cycles, and provide liquidity during times of crisis. However, this flexibility depends strongly on institutional credibility and trust. When that trust begins eroding and weakens, inflation emerges, and if it collapses entirely, hyperinflation follows.
Beginning in the late 1990s, Zimbabwe was spending more than it earned, while its economy was getting smaller. Government expenditures began to exceed revenues gained, while output in key sectors, such as agriculture, fell sharply. Rather than adjusting the fiscal policy or restoring production, deficits were financed through the use of policies such as monetary expansion (Makochekanwa, 2009). This use of monetary expansion led to a period of inflation. In this period, despite inflation being present, money still functioned. However, rising prices showed that too much money was being created compared to what the economy was producing.
Economists define hyperinflation as price increases exceeding 50 percent per month, but its defining characteristic is the collapse of confidence in money itself (Hanke & Kwok, 2009). Zimbabwe crossed this threshold during the mid-2000s. During this time period, currency in Zimbabwe ceased to function as a reliable unit of account, leading people to start losing trust in it. According to empirical estimates, Zimbabwe experienced one of the worst hyperinflation crises in history, with it peaking at an astounding monthly rate of 79.6 billion percent in mid-November 2008. This led to people simply refusing to use the Zimbabwe dollar, and the hyperinflation came to an abrupt halt. This hyperinflation was caused by rapid money printing while the economy was shrinking (Hanke & Kwok, 2009). This inflation also caused the Reserve Bank of Zimbabwe to issue the $100 trillion note in January 2009, one of the world’s largest denominations of currency in history, in an attempt combat the rapidly devaluing currency (Smithsonian National Museum of American History, n.d.).
When money fails to perform its core functions, economic exchange and people’s wants and needs do not disappear; they adapt. In Zimbabwe, as the national currency lost meaning, individuals and firms adapted, moving from using the national currency to direct exchange of goods, informal exchange, and foreign currencies. Goods and services replaced domestic money as mediums of exchange and trade (Mail & Guardian, 2007). In a way, Zimbabwe’s economy was forced to restart from the very beginning through barter trade. Barter, despite being inefficient and costly, becomes preferable when using money guarantees a loss. Zimbabwe’s partial return to barter-like behavior was a rational adaptation and “survival strategy” (Makochekanwa, 2009) to a broken monetary system rather than economic irrationality.
After years of economic collapse and informal adaptations, in 2009 Zimbabwe abandoned its national currency and adopted a multicurrency system dominated by the US dollar. This policy, also called “dollarization”, occurs when a country starts to replace its domestic currency with a foreign currency, opting to use it for everyday pricing and transactions (Baliño, 2003). This move also led to the pausing of hyperinflation by removing the government’s ability to print money. While prices stabilized, and money regained its basic functions (IMF, 2010), dollarization also imposed constraints, with some politicians growing concerned that by using foreign currencies like the U.S. dollar, Zimbabwe lost control over its own money and became dependent on money coming in from other countries (IMF, 2010).
In 2024, Zimbabwe introduced a new currency called the ZiG (Zimbabwe Gold), managed by the Reserve Bank of Zimbabwe. The ZiG is backed by gold and foreign exchange reserves, showing an effort to limit money creation and keep the currency stable (World Economic Forum, 2024). Economically, the ZiG sits as a middle ground between barter and traditional fiat money. Because it is backed by gold, the government cannot create it freely, which helps rebuild trust in a country where confidence in fiat currency has previously collapsed. This year marks a significant improvement for Zimbabwe, with early signs showing that the ZiG has helped bring inflation back to single digits for the first time in 29 years (Marawanyika, 2026a). Although inflation is now below 10 percent, the key challenge will be maintaining that stability over time (Marawanyika, 2026b).
Zimbabwe’s monetary history serves as both an example and a possible warning to the modern world. It illustrates how the stability of fiat money depends entirely on trust. When this trust shatters, inflation can rapidly escalate to hyperinflation, forcing societies to reconstruct their entire monetary systems from the ground up.
