“If you want to stop inflation immediately, you install a currency board.” - Steve Hanke
For most of my professional career, I’ve watched emerging governments and central bankers repeat the same tragic cycle of discretionary monetary policy, political interference, inflation, and the eventual collapse. The reality is that they rarely confront the root cause of hyperinflation - a central bank with discretionary power and no rules to dictate policy.
This disaster of philosophy propagated by the IMF has motivated much of my life work; designing, implementing, and defending currency boards. They are the most reliable monetary institutions ever invented - simple, transparent, rule‑bound, and immune to political manipulation.
We need a return to rules-based monetary systems.
What a Currency Board Is — and What It Is Not
A currency board is a monetary machine, not a political instrument.
What are the main tenets I stick to when tasked with designing a currency board?
A TRUE currency board:
- Issues domestic currency only when fully backed by foreign reserves
- Maintains a fixed exchange rate, set in law
- Has no discretionary monetary policy
- Cannot lend to governments or cronies
- Operates automatically, without committees or forecasts
A currency board is not:
- A central bank with a new mandate
- A “managed peg”
- A tool for political tinkering
Why Currency Boards Work
The power of a currency board comes from its constraints. Politicians cannot print money to finance deficits. Central bankers cannot manipulate interest rates. Markets cannot be spooked by the whims of a monetary committee.
The results are consistent:
- Inflation collapses to the anchor currency’s level
- Interest rates fall
- Confidence returns
- Growth resumes
- Capital flight reverses
These are not theoretical claims. They are empirical facts I have observed firsthand in Estonia, Lithuania, Bulgaria, Bosnia and Herzegovina, and Hong Kong.
The Core Argument
Hanke's Thesis: Central banks with discretionary monetary policy are inherently prone to political capture and inflation. The best institutional design eliminates discretion entirely — which is precisely what currency boards do.
The argument is not merely theoretical. Every hyperinflation ever documented in the Hanke-Krus Hyperinflation Table — all 62 episodes — was caused by a central bank printing money. Not a single hyperinflation has occurred under a properly functioning currency board in the entire 175-year history of the currency board institution.
"The best way to eliminate the possibility of a hyperinflation would be to mothball central banks and put them in museums." — Steve H. Hanke
"For developing countries, the best way to eliminate the possibility of a hyperinflation would be to mothball their central banks and put them in museums." — Steve H. Hanke
Why Central Banks Fail
Central banks fail for structural, not personal, reasons. Even well-intentioned central bankers operate within an institutional framework that creates systematic pressures toward inflation:
- Political capture — Governments pressure central banks to finance fiscal deficits. Central banks rarely have the institutional independence to resist this pressure permanently.
- Discretionary policy — Without hard rules, monetary policy becomes a tool for short-term economic management, which invariably creates long-term instability.
- Opacity — Central bank decision-making is complex, multi-faceted, and opaque. Currency boards, by contrast, operate mechanically and transparently.
- Lender of last resort — The lender-of-last-resort function creates moral hazard and provides a mechanism for financing government spending through the back door.
Hanke's Key Principle: "A central bank with a flexible exchange rate can extend credit to the fiscal authority and therefore, contrary to a currency board, provides no fiscal discipline."
Historical Evidence: Central Bank Failures
Country | Period | Peak Inflation | Cause |
Hungary | 1945–1946 | 4.19 × 10^16% per month (world record) | Central bank financed post-war reconstruction |
Germany (Weimar) | 1921–1923 | 29,525% per month | Central bank printed marks to pay war reparations |
Zimbabwe | 2007–2008 | 7.96 × 10^10% (Nov 2008) | Reserve Bank of Zimbabwe financed Mugabe government spending |
Yugoslavia | 1992–1994 | 313 million % per month (Jan 1994) | Yugoslav central bank financed war spending and ethnic conflict |
Venezuela | 2016–present | Exceeded 1,000,000% annual (2018) | Banco Central de Venezuela monetized government deficits |
Every single case: a central bank, under political pressure, printed money. Zero exceptions in 62 documented hyperinflations.
In the entire historical record, there is not a single hyperinflation that occurred under an orthodox currency board. Every hyperinflation in the Hanke-Krus table occurred under a central bank with discretionary monetary policy. The evidence could not be clearer: central banks are the proximate institutional cause of hyperinflation, and currency boards are the institutional cure.
Under Currency Boards: Zero Hyperinflations
This is the most powerful empirical fact in monetary economics:
The Perfect Record: In the entire historical record of currency boards — 70 boards across 175 years since Mauritius in 1849 — there has not been a single hyperinflation under a properly functioning currency board. Not one.
The mechanism is simple. A currency board cannot print money beyond its foreign reserve holdings. There is no mechanism for it to finance government deficits. Fiscal profligacy hits an immediate hard constraint: the government must find real financing or cut spending.
Transparency vs. Opacity
Currency boards are the most transparent monetary institutions ever devised:
- Balance sheet is simple: foreign reserves on one side, domestic currency on the other
- Exchange rate is fixed by law — no guessing, no press conferences, no forward guidance
- Operations are mechanical — no committee meetings, no discretionary judgments
- Accountability is clear — the board either maintains the peg or it does not
Compare this to modern central banking, where:
- Policy decisions emerge from committees using complex, opaque models
- "Forward guidance" is itself an instrument of discretionary policy
- True reserve positions are often difficult to assess
- Political influence is real but rarely acknowledged
Reference: "The Disregard for Currency Board Realities"
In his paper "The Disregard for Currency Board Realities" (Cato Journal), Hanke systematically dismantles the academic and policy objections to currency boards that have been used to block their adoption in countries like Indonesia (1998) and Russia (1990s).
The paper argues that critics of currency boards typically conflate pseudo currency boards (which allow some discretion) with orthodox currency boards (which allow none). The failures that critics cite are invariably failures of pseudo boards, not orthodox ones.
