Inflation, Debt, and the Quiet Tax on Savers

Most people think inflation is only about prices going up. That is true, but it is not the whole story.

Inflation also decides who quietly loses purchasing power and who may be protected. When inflation is higher than the interest you earn on cash, your bank balance may look safe, but the money can buy less each year. When inflation is higher than wage growth, your salary may rise, but your standard of living can still fall. When the government has a large debt burden, inflation can also become a hidden way to reduce the real value of that debt.

This article explains that mechanism clearly.

The basic problem: prices are rising faster again

The United States Consumer Price Index rose 4.2 per cent over the year to May 2026. The Consumer Price Index is a measure of the average change in prices paid by consumers for goods and services. In plain language, it is one of the main ways economists measure inflation. (1)

The May 2026 figure matters because inflation had already fallen from the 2022 spike, then started rising again. Energy was a major reason. Over the year to May 2026, energy prices rose 23.5 per cent, and petrol prices rose 40.5 per cent. (1)

This does not prove that the United States is repeating the 1970s. History never repeats with perfect accuracy. The economy today is different in many ways: labour unions are weaker, global supply chains are different, technology is more important, and the Federal Reserve has more credibility than it had in the 1970s.

However, the comparison is still useful because the 1970s showed what can happen when inflation falls, people relax, and then inflation comes back again.

In the Great Inflation period, inflation began rising in the mid-1960s and reached more than 14 per cent in 1980. The Federal Reserve eventually fought it with very high interest rates. The federal funds rate, which is the short-term interest rate targeted by the Federal Reserve, reached nearly 20 per cent during the Volcker period. (2, 3)

That strategy worked, but it was painful. High interest rates helped break inflation, but they also contributed to recession, unemployment, and financial stress.

Why the same solution is harder today

The traditional way to fight inflation is simple in theory. The central bank raises interest rates. Higher interest rates make borrowing more expensive. People and businesses borrow less, spend less, and demand cools. When demand cools, inflation usually slows.

But there is a problem: today, government debt is much larger.

United States total public debt was about 39.17 trillion dollars in late May 2026. United States gross domestic product in the first quarter of 2026 was about 31.82 trillion dollars at a seasonally adjusted annual rate. (4, 5)

Gross domestic product means the total value of goods and services produced by a country. It is often used as a rough measure of the size of the economy.

Here is the simple debt-to-economy calculation:

Government debt: 39.17 trillion dollars

Size of the economy: 31.82 trillion dollars

Debt compared with the economy:

\[39.17 \div 31.82 = 1.231\] \[1.231 \times 100 = 123.1\%\]

So, on this broad gross-debt measure, total public debt is around 123 per cent of the size of the economy. This compares a stock of debt with one year of annualised economic output, which is the conventional way debt-to-GDP ratios are presented.

There is another important debt measure called debt held by the public. This excludes debt that one part of the government owes to another part of the government. The Congressional Budget Office projects that debt held by the public will be about 101 per cent of gross domestic product in 2026 and rise to 120 per cent by 2036. (6)

Either way, the direction is clear: debt is high, and interest costs matter much more than they used to.

Why interest rates become dangerous when debt is high

Interest is the cost of borrowing money.

If you owe 1,000 dollars and the interest rate is 5 per cent, the annual interest cost is:

\[\$1{,}000 \times 0.05 = \$50\]

The same logic applies to governments, except the numbers are much larger.

The average interest rate on interest-bearing United States federal debt was about 3.35 per cent in May 2026. Using the broad debt figure of about 39.17 trillion dollars, a rough annualised interest calculation is: (7)

\[\$39.17 \text{ trillion} \times 0.0335 = \$1.31 \text{ trillion}\]

This is only a rough calculation because not all debt resets at once, the government has different types of debt with different maturities, and the broad debt total is not identical to the interest-bearing debt base used in the Treasury’s average-rate series. But it shows the scale of the issue.

Now imagine if the average interest rate on the debt were much higher. For example, at 10 per cent:

\[\$39.17 \text{ trillion} \times 0.10 = \$3.917 \text{ trillion}\]

At 16 per cent:

\[\$39.17 \text{ trillion} \times 0.16 = \$6.267 \text{ trillion}\]

Those numbers are not a prediction. They are a stress test. They show why very high interest rates become difficult when debt is already large.

This creates a policy trap.

If inflation rises, the central bank may want to raise interest rates. But higher rates make government borrowing more expensive. If borrowing becomes too expensive, the government may need to borrow even more just to pay interest. That can make the debt problem worse.

This does not mean the Federal Reserve cannot raise rates. It can. But it does mean the political and financial pressure against very high rates is much stronger than it was when debt was lower.

The 1940s example: reducing debt without openly defaulting

After the Second World War, United States debt was also very high. The government had borrowed heavily to finance the war.

One way the debt burden was reduced was through growth. Another was a policy now commonly described as yield curve control.

Yield curve control means the central bank keeps government bond yields below a chosen level. A bond yield is the return investors receive from holding a bond. If the central bank wants bond yields to stay low, it may need to buy bonds when private investors do not want to buy enough at that low yield.

In April 1942, the Federal Reserve formally committed to keeping short-term Treasury bill rates at three-eighths of 1 per cent, which is 0.375 per cent. It also implicitly capped long-term Treasury bond yields at around 2.5 per cent. (8)

This kept government borrowing costs low. But there was a cost to savers.

If inflation is 10 per cent and a saver earns 2 per cent interest, the saver is not really getting richer. The saver is losing purchasing power.

The simple real-return approximation is:

\[\text{interest rate} - \text{inflation rate} = \text{approximate real return}\]

If interest is 2 per cent and inflation is 10 per cent:

\[2\% - 10\% = -8\%\]

That means the saver’s purchasing power falls by about 8 per cent in a year.

This is called financial repression.

Financial repression means savers receive interest rates below inflation, often alongside policies that keep rates low or channel savings towards government debt. The government does not openly take money from savers. Instead, inflation reduces the real value of money, while low interest rates stop savers from being fully compensated. Similar policies were used extensively in the United States and other advanced economies after the Second World War. (9)

It is a quiet transfer.

Borrowers benefit because the real value of their debt falls. Savers lose because the real value of their cash and fixed-rate bonds falls.

Why cash can lose value even when the bank balance rises

This is the most important point for ordinary households.

Suppose someone has 150,000 dollars in a savings account.

The national average savings rate in May 2026 was 0.38 per cent. (10)

The interest earned in one year is:

\[\$150{,}000 \times 0.0038 = \$570\]

So the account rises from 150,000 dollars to 150,570 dollars before tax.

That looks safe. The number has gone up.

But if inflation is 4.2 per cent, the cost of the same goods and services rises by:

\[\$150{,}000 \times 0.042 = \$6{,}300\]

To keep the same purchasing power, the saver would need 156,300 dollars after one year.

But the saver only has 150,570 dollars.

The year-end purchasing-power shortfall, measured in future dollars, is:

\[\$156{,}300 - \$150{,}570 = \$5{,}730\]

So, even though the account balance rose by 570 dollars, the saver is 5,730 dollars short of the amount needed at year-end to keep up with inflation.

The exact real-return formula is:

\[\text{real return} = \frac{1 + \text{interest rate}}{1 + \text{inflation rate}} - 1\]

Using 0.38 per cent interest and 4.2 per cent inflation:

\[\frac{1.0038}{1.042} - 1 = -0.03666\]

That is a real return of about negative 3.67 per cent.

On 150,000 dollars:

\[\$150{,}000 \times 0.03666 \approx \$5{,}499\]

The exact method gives a loss of about 5,499 dollars measured in today’s purchasing power. The 5,730-dollar shortfall is measured in year-end dollars. Deflating that future-dollar shortfall by 4.2 per cent gives the same result:

\[\$5{,}730 \div 1.042 \approx \$5{,}499\]

The lesson is simple: cash can be safe in nominal terms but unsafe in real terms.

Nominal means the number printed on the bank statement.

Real means what the money can actually buy.

Why wages matter too

The same logic applies to income.

In May 2026, average hourly earnings for private-sector workers in the United States rose 3.4 per cent over the previous year. But inflation was 4.2 per cent. (11, 1)

A worker may hear, “Your pay went up.” But if prices rose faster than pay, the worker is worse off in purchasing-power terms.

The simple calculation is:

\[\text{wage growth} - \text{inflation} = \text{approximate real wage growth}\] \[3.4\% - 4.2\% = -0.8\%\]

The exact calculation is:

\[\frac{1.034}{1.042} - 1 = -0.00768\]

That means real hourly earnings fell by about 0.77 per cent.

For a person earning 60,000 dollars per year, a 0.77 per cent loss of purchasing power is roughly:

\[\$60{,}000 \times 0.00768 \approx \$461\]

Again, the salary number can rise while real purchasing power falls.

This is why inflation is so politically and socially dangerous. It creates losses that are hard to see. People do not receive a bill called an “inflation tax”. They simply notice that groceries, petrol, insurance, rent, repairs, and everyday services absorb more of their income.

The bank-capital issue: why Treasury buyers matter

Governments finance deficits by issuing bonds. A Treasury bond is a promise by the government to pay money in the future, with interest along the way.

Someone has to buy those bonds.

The buyers can include households, pension funds, foreign investors, banks, and the central bank. When private buyers are willing to buy at low yields, the government can borrow cheaply. When buyers demand higher yields, borrowing becomes more expensive.

A final rule issued by United States bank regulators on 25 November 2025 took effect on 1 April 2026. The rule modified the enhanced supplementary leverage ratio, which is a capital rule for the largest and most systemically important banking organisations. In plain English, a bank-capital rule tells banks how much financial cushion they must keep relative to the size of their balance sheet. (12)

A balance sheet is a list of what a bank owns and what it owes.

The regulators said the change was intended to reduce disincentives for low-risk activities such as intermediating in United States Treasury markets. If leverage requirements are less binding, large banks may have more room to hold or intermediate low-risk assets such as Treasury securities. That can help the Treasury market function more smoothly. (12)

But there is an important distinction.

Banks buying Treasury securities is not exactly the same as the central bank printing money. Commercial banks can create deposit money through lending and asset purchases, but central-bank money creation and commercial-bank balance-sheet expansion are different mechanisms.

A careful way to say it is this:

If banks have more balance-sheet capacity, they may be able to absorb or intermediate more government debt. That can help keep bond yields lower than they otherwise would be. But it does not guarantee that banks will buy unlimited Treasuries, and it does not prove that inflation will automatically surge.

Why low yields plus high inflation favour borrowers over savers

The key signal to watch is not inflation alone. It is inflation compared with interest rates.

If inflation is 4.2 per cent and a saver earns 0.38 per cent, the saver loses purchasing power.

If inflation is 4.2 per cent and a government can borrow at 3.5 per cent, the real burden of that borrowing may be reduced by inflation.

If inflation is 10 per cent and bond yields are held at 3 per cent, the transfer becomes much larger.

That is the core mechanism of financial repression.

It does not need a dramatic announcement. It does not require a formal default. The government pays back the dollars it owes, but those dollars buy less. Savers and bondholders are repaid in full nominally, but not fully in purchasing-power terms.

This is why inflation is sometimes called a hidden tax.

It does not show up as a tax rate. But it reduces the value of money.

Who is hurt and who may benefit

The people most hurt by this environment are usually cash savers, fixed-income savers, and wage earners whose pay does not keep up with inflation.

A fixed-income saver is someone who owns assets that pay a fixed amount, such as many bonds. If the payment is fixed but prices rise, the payment becomes less valuable.

People who may be better protected are those who own assets that can reprice with inflation.

Examples include some businesses, property, infrastructure, commodities, and gold.

But this needs careful thinking.

Stocks are not automatically protected. If a company cannot raise prices, its profit margins may fall. If interest rates rise, stock valuations may fall. If consumers become weaker, sales may fall.

Property is not automatically protected either. It can benefit from inflation over the long term, but higher mortgage rates can reduce affordability and put pressure on prices.

Gold can protect against monetary instability, but it produces no income and can be volatile.

So the lesson is not “buy hard assets blindly”.

The lesson is that investors need to understand the difference between nominal safety and real safety.

Cash protects the number on the statement.

Assets may protect purchasing power, but only if bought at sensible prices and held with discipline.

The practical conclusion

The important issue is not whether the 1970s repeat exactly. They almost certainly will not.

The important issue is whether the same economic pressure is returning in a modern form: inflation above savings rates, inflation above wage growth, high government debt, and strong pressure to keep borrowing costs manageable.

When those forces appear together, savers need to think differently.

A bank balance can rise while purchasing power falls.

A salary can rise while living standards fall.

A government can repay its debt in nominal terms while inflation reduces the real burden.

That is why inflation is not just a price problem. It is a distribution problem. It decides who pays and who is protected.

For ordinary savers, the first step is understanding the arithmetic. If your money earns less than inflation, it is shrinking in real terms. If your wages rise less than inflation, your labour is being paid less in real terms. If bond yields are held below inflation, savers are helping reduce the debt burden without ever voting for a tax increase.

The quiet danger is not that money disappears.

The quiet danger is that it stays in your account while its purchasing power slowly drains away.

That is the real inflation risk.
