Setelinleikkaus: When Finns snipped their cash in half to curb inflation

Original Article ↗ Hacker News Discussion ↗

Finland’s post‑WWII experiment of literally cutting banknotes in two to fight inflation prompts a wider look at how governments try to control prices and money supply, from rationing and demonetisation to modern central bank tools. Commenters contrast quantity-based interventions like note haircuts with today’s interest-rate targeting, arguing over whether recent inflation was driven more by pandemic-era “money printing” or by energy shocks and the war in Ukraine. Many see future digital currencies and account “freezes” as technically feasible but politically dangerous, raising fears of granular state control over what citizens can buy.

Debate over what “controls” inflation

  • Some argue the article wrongly implies price controls are a solution; they see asset freezes and purchase restrictions as de facto price controls or even “communism,” and predict economic collapse if widely used.
  • Others stress the piece is descriptive/predictive, not an endorsement, and distinguish:
    • Price controls = capping specific prices.
    • Currency/asset controls = limiting how much and where money can be spent.
  • Several note that rationing and price controls were common wartime tools; the problem is how to exit them without massive shocks.

Causes of recent inflation

  • One camp blames central banks’ pandemic-era money expansion (“money printing”) as the main driver, citing dramatic growth in monetary aggregates.
  • Critics counter that:
    • EU inflation timing tracks energy shocks and Russia’s invasion of Ukraine (gas, electricity, food, metals).
    • Monetary aggregates like M1 include definitional changes (e.g., adding savings accounts), so raw graphs can mislead.
    • Inflation is multi-causal: energy, supply chains, war, shipping disruptions, and monetary policy all interact.
  • Disagreement persists over how much to attribute to central banks vs. energy/geopolitics.

Setelinleikkaus and other monetary experiments

  • Finnish note-cutting is seen as historically interesting but largely ineffective because only physical cash (a small share of money) was hit; bank deposits were untouched.
  • Related examples discussed: Belgian postwar “Operation Gutt,” Indian demonetization, Turkish and Brazilian currency re-denominations, Czechoslovak and Indonesian reforms, and US gold confiscation.
  • Many note such measures are politically explosive and often perceived as expropriation or “wage theft,” even when paired with bonds or compensation.

Digital money, CBDCs, and “quantitative freezing”

  • The article’s notion of future “quantitative freezing” of digital accounts (blocking certain purchases while allowing essentials) alarms many commenters.
  • Concerns: path to totalitarian control over individuals’ spending; difficulty of evasion if cash disappears; questionable implementability without massive loopholes.
  • Proposed “hedges” include physical gold, foreign currency, or foreign bank accounts, though others note regimes can criminalize or strongly constrain their use.

Central banking mechanics and effectiveness

  • Long subthread on how modern central banks work:
    • Interest rates are targeted; tools include open market operations, interbank facilities, and interest on reserves.
    • Mechanically, all of these still adjust the quantity and terms of money-like assets.
  • Some argue interest-rate policy demonstrably tamed inflation in many countries since the 1990s; others call it “economic theatre,” citing Japan’s low inflation under near-zero rates and QE’s mixed record.
