100 ZiG (Zimbabwe Gold)

The 100 ZiG denomination was included in the original comprehensive ZiG banknote series unveiled by the Reserve Bank of Zimbabwe on April 5, 2024. Like the 50 and 200 ZiG notes, its release was postponed indefinitely on May 30, 2024, as monetary authorities determined that introducing higher denominations could exacerbate inflationary pressures during the critical early phase of the new currency's adoption. The Reserve Bank's cautious approach prioritized currency stabilization by limiting circulation to the 10 and 20 ZiG denominations.

The ZiG was Zimbabwe's sixth attempt at currency stabilization since the country's abandonment of the Zimbabwean dollar in 2009 in favor of a multi-currency system. The gold backing mechanism — supported by 2,522 kilograms of gold reserves and USD 100 million in foreign currency — was intended to provide credibility that previous currency iterations lacked. Restricting higher denominations from circulation was seen as prudent monetary management to preserve this credibility.

As of early 2026, the 100 ZiG remained in planned status, with the Reserve Bank indicating its eventual inclusion in subsequent phases of the BiG5 series rollout. The specific timeline depends on ongoing assessments of Zimbabwe's monetary stability and inflation metrics.
