Fiat Currency

Economy & power / Explainer & opinion

Fiat currency.Debt, trust
and power.

The money in your account is part of a system of promises. Understanding who creates it, what sustains it, and how its purchasing power changes is a starting point for questioning the system.

Modern currency is not redeemable for a fixed quantity of gold. Its usefulness depends on public acceptance and confidence in the institutions behind it. RBA: What is money?

Look beyond the note. Follow the promises behind it.

Purchasing power
What your money can actually buy.
01 / The foundation

What fiat currency actually means.

Fiat currency has no promise of conversion into a fixed amount of gold or silver. Its value rests on its acceptance as payment and confidence that it will remain useful. In modern economies, money includes physical cash and deposits held at banks. RBA explainer

A currency can function without commodity backing. The harder question is whether the institutions managing it preserve trust and purchasing power over time.

02 / Follow the entries

How banks create money.

When a commercial bank makes a loan and credits the borrower’s account, it generally creates a new deposit. On the bank’s books, the loan is an asset and the deposit is a liability. This adds spendable money, alongside a matching obligation to repay. Bank of England explanation

One loan. Two balance-sheet entries.

A simplified $10,000 bank loan, before any spending or interest.

If $1,000 of principal is repaid from this deposit, the loan and deposit each fall to $9,000. Principal repayment removes deposit money. How deposits are created and removed

Creating a deposit does not, by itself, create a house, a factory or additional real wealth. New purchasing power arrives with new debt. Money creation and wealth

What limits banks’ ability to lend?

Banks face capital and liquidity requirements, funding and settlement costs, credit risk, demand from borrowers and monetary policy. They cannot lend without limits. A simple story in which banks repeatedly multiply a fixed pot of reserves misses how modern lending works. Read about the constraints

The example shows a loan that has been funded and credited. An unused credit limit is not yet a spendable deposit. It also leaves out interest and transfers between banks.

03 / The everyday cost

The number stays the same.
What it buys can change.

Inflation is a rise in the general level of prices. It can develop when demand runs ahead of supply, production costs increase, or expectations of future price rises influence decisions. Money and credit matter, but “more money” is not a complete explanation of every inflation episode. RBA: Causes of inflation

When prices rise faster than your income, your standard of living is squeezed. Cash also loses purchasing power if the return it earns fails to keep pace with inflation. The impact depends on wages, savings, debts and the goods a household needs to buy.

When inflation slows but stays positive, prices are still rising. They are simply rising more slowly. This is why a lower inflation headline can coexist with an expensive grocery bill. RBA: Why prices do not drop when inflation does

Purchasing power is the measure that reaches the kitchen table.

04 / The global picture

Watch the evidence behind the headlines.

In their 2025 Rio de Janeiro Declaration, BRICS members supported local-currency financing and continued work on cross-border payment cooperation. These are concrete proposals worth watching. BRICS declaration, paragraphs 49–50 (PDF)

Central banks have also accumulated gold. A September 2026 Federal Reserve research note cautions that much of the recent rise in gold’s reserve value reflects higher gold prices, and that Treasury securities remain important reserve assets. Read the research note

Our reading: these developments deserve scrutiny, but they do not establish that a dollar collapse or a new gold-backed monetary system is inevitable. Follow implemented changes in trade, payments and reserve holdings, as well as political announcements.

05 / Do Not Comply

Understanding should lead to scrutiny.

A financial system that shapes everyday life should be open to public challenge. Our concern is how power is exercised: which activities receive credit, whose interests shape policy, and who carries the consequences when decisions go wrong.

Criticism is strongest when its explanations stand up to inspection. Ask precise questions, follow the evidence, and expect those who manage money to account for their decisions.

  • Who gets the credit?

    Which people, businesses and activities gain access to lending, and on what terms?

  • Who gains?

    How are the benefits of financial decisions distributed across households and institutions?

  • Who carries the risk?

    When promises cannot be kept, where do losses fall, and who is held accountable?

Real sovereignty begins with understanding the system itself.
