A heavily indebted state has a way to lighten its load that is neither voted on nor seen: letting inflation and rates kept too low gnaw away, year after year, at the real value of its debt. The bill is paid by the holders of that debt, that is, the savers. Economists call this set of devices "financial repression", and its engine, the "inflation tax".
1 The invisible tax
To levy without ever showing it.
The definition
A transfer from creditor to debtor
Financial repression refers to the policies by which a state channels toward itself the savings that, in a free market, would go elsewhere, and does so at a cost lower than the market's. The result: a silent transfer from creditors (the savers) to debtors (the state, first and foremost). Its political appeal lies in its opacity: unlike a tax increase or budget cuts, which are voted on and held against you, it acts without debate. Carmen Reinhart and Belen Sbrancia describe it as "a subtle type of debt restructuring".
2 The inflation tax
The engine of the mechanism.
Erosion through prices
You are taxed in proportion to the money you hold
A government debt is denominated in nominal money. If prices rise, its real value melts away: the state repays in money that is worth less, without a single cent changing hands. This is the inflation tax, paid by every holder of money and fixed-rate bonds. The rule is mechanical: at 10% inflation, whoever holds €100,000 loses about €10,000 in purchasing power. The income the state draws from issuing money goes by a related name, "seigniorage". As Milton Friedman put it, "Inflation is the one form of taxation that can be imposed without legislation".
3 Negative real rates
The chief weapon of repression.
A yield below inflation
When safe savings earn less than rising prices
The central lever is the negative real rate: a yield on safe savings kept below inflation. Each year, the purchasing power of savings falls back, and the debt lightens by just as much. The effect is slow but powerful: Reinhart and Sbrancia estimated that in the United States and the United Kingdom, these negative real rates liquidated on average 3 to 4% of GDP in debt per year between 1945 and 1980. It was in this way, more than through growth, that the West cut its postwar debt. US debt fell from 106% of GDP in 1946 to 23% in 1974.

4 Captive demand
For rates to stay low, you need forced buyers.
The obliged customers
Banks, insurers, pension funds, central banks
Rates do not stay low on their own: regulation manufactures captive buyers of public debt. Under the Basel rules, holding one's own government's debt costs a bank no capital and counts as the most liquid asset there is; insurers and pension funds are pushed in the same direction. Central banks' asset purchases add a buyer of last resort. Japan offers the extreme form of this: its central bank holds roughly half of the government's debt. This forced demand keeps yields low, so the cost of the debt low, so the saver's return low.
5 Takeaways
To remember.
✓
Financial repression transfers wealth from the creditor (the saver) to the debtor (the state), with no visible tax and no vote.
✓
Its engine is the inflation tax: you are levied in proportion to the money and bonds you hold.
✓
Its weapon is the negative real rate, sustained by a captive demand (regulation, central banks).
✓
Honest debate: often presented as the "lesser evil" against default or austerity; indexing tax brackets is its partial antidote.
