For over four decades, Professor Steve H. Hanke has served as an architect of monetary stabilization programs across four continents. This timeline documents each country where he provided currency stabilization advice — through dollarization, currency boards, or other hard-money reforms.
🌍 Scope: This record spans 1990 to the present, covering currency board installations, dollarization programs, and advisory roles where Hanke's recommendations were either implemented or formally presented to governments.
The Timeline
Year | Country | Action | Outcome |
1990–91 | 🇦🇷 Argentina | Designed Convertibility system blueprint | Convertibility Law enacted April 1991; ended hyperinflation immediately; peso fixed 1:1 to USD |
1992 | 🇪🇪 Estonia | Installed currency board with Kurt Schuler and Lars Jonung | Replaced Soviet ruble with the Estonian kroon; ended hyperinflation; economy stabilized within months |
1993 | 🇷🇺 Russia | Blueprint for ruble reform co-authored with Lars Jonung and Kurt Schuler | Not implemented; ruble crashed in 1998 financial crisis, as Hanke predicted |
1994 | 🇱🇹 Lithuania | Currency board as State Counselor (1994–96) | Litas pegged to USD via currency board; high inflation ended; stable economy followed |
1995–96 | 🇻🇪 Venezuela | Presidential adviser on currency stabilization | Reform not implemented; currency mismanagement continued; hyperinflation eventually erupted in 2016 |
1996–97 | 🇧🇦 Bosnia-Herzegovina | Designed currency board under Dayton Accords as special U.S. government adviser | IMF-backed currency board established; Bosnian mark (later euro) achieved monetary stability |
1997 | 🇧🇬 Bulgaria | Installed currency board as Chief Presidential Adviser to President Petar Stoyanov | Ended 242%/month hyperinflation within weeks; transformed Bulgarian economy; Hanke named "Father of the Bulgarian Currency Board" |
1998 | 🇮🇩 Indonesia | Proposed currency board during Asian financial crisis as adviser to President Suharto | Not implemented despite Suharto's initial interest; IMF and U.S. Treasury opposed; severe crisis continued and Suharto resigned |
1999 | 🇲🇪 Montenegro | Replaced hyperinflating Yugoslav dinar with Deutsche Mark as State Counselor (1999–2003) | Monetary stability restored immediately; Montenegro became one of the most stable economies in the Balkans |
2000 | 🇪🇨 Ecuador | Supported official dollarization when Ecuador adopted USD as sole legal tender | Successful dollarization; Ecuador has maintained monetary stability and avoided hyperinflation since |
2008 | 🇿🇼 Zimbabwe | Estimated peak hyperinflation using PPP methodology (with Alex Kwok); advocated dollarization | Zimbabwe eventually dollarized informally in 2009, ending the hyperinflation; second episode documented in 2017 |
2012–present | 🇮🇷 Iran | Monitoring hyperinflation via Troubled Currencies Project; calling for currency board or dollarization | Government has resisted reform; rial continues to collapse under sanctions pressure; Hanke's estimates remain primary source |
2016–present | 🇻🇪 Venezuela | Monitoring hyperinflation after government ceased publishing data; advocating official dollarization | Government has resisted; partial informal dollarization occurring organically; Hanke's estimates remain primary record |
2020–present | 🇱🇧 Lebanon | Monitoring hyperinflation following currency peg collapse; calling for monetary reform | Crisis ongoing; political gridlock has prevented reform; informal dollarization expanding among population |
Success Rate Analysis
Every country where Hanke's full prescription was implemented — Estonia (1992), Lithuania (1994), Bulgaria (1997), Bosnia-Herzegovina (1997), Montenegro (1999) — achieved lasting monetary stability. In every case, inflation fell sharply within weeks of implementation. None of these countries has since experienced a currency crisis or hyperinflation.
Every country where Hanke's prescription was rejected or only partially implemented — Indonesia (1998), Russia (1990s), Venezuela (1995) — subsequently suffered prolonged monetary crises. Indonesia experienced a devastating currency collapse in 1998. Russia's ruble crashed in 1998. Venezuela descended into hyperinflation by 2016 — exactly as Hanke had warned two decades earlier.
✅ Implemented & Successful

6 out of 6 implementations succeeded
❌ Not Implemented
Russia (1993), Venezuela (1995), Indonesia (1998)
All 3 rejections led to major crises
Bulgaria: The Signature Achievement
Of all Hanke's interventions, Bulgaria (1997) stands as the most dramatic:
- In January 1997, Bulgaria's monthly inflation rate reached 242%
- The government was collapsing; the banking system was in crisis
- President Petar Stoyanov appointed Hanke as Chief Presidential Adviser
- Within weeks, a currency board pegged the lev to the Deutsche Mark
- Inflation fell to single digits within the year
- Bulgaria's currency board remains in operation today (now pegged to the euro)
- The Bulgarian Academy of Sciences awarded Hanke an Honorary Doctorate in 2013 for this work
Montenegro: The Only Unilateral Dollarization Hanke Designed
In 1999, as State Counselor to Montenegro, Hanke advised the government to unilaterally replace the Yugoslav dinar — which was hyperinflating under Slobodan Milosevic's Belgrade regime — with the Deutsche Mark. This was a bold and unprecedented move:
- Montenegro had no agreement with Germany or the Bundesbank
- The substitution was done unilaterally
- It worked immediately — monetary stability was restored
- Montenegro later adopted the euro (2002) when Germany did
- It remains dollarized (euro-ized) today
The Troubled Currencies Project
To institutionalize real-time monitoring of at-risk currencies globally, Hanke founded the Troubled Currencies Project at the Cato Institute in 2013. The project applies the same PPP/black-market methodology used in the Hanke-Krus Hyperinflation Table to provide ongoing estimates for countries whose governments suppress or falsify monetary data.
