Question 1

What is a central bank digital currency?

Accepted Answer

A **central bank digital currency (CBDC)** is digital money issued by a central bank — a direct claim on the central bank in electronic form, rather than a claim on a commercial bank.

**The distinction that defines it.** The money in your bank account is **not** central bank money. It is a liability of your bank — a promise to pay you — which is why deposit guarantee schemes exist. **Cash is** central bank money: a direct claim on the state, with no intermediary. A CBDC would extend that property to digital form.

**Two types are discussed:**

**Retail CBDC** — usable by the public for everyday payments. This is what people mean by "digital pound" or "digital euro".

**Wholesale CBDC** — restricted to financial institutions for interbank settlement. Considerably less controversial and further advanced.

**Why central banks are interested:**

**Declining cash use.** If cash disappears, the public loses access to central bank money entirely, and payments become wholly dependent on private providers.

**Payment system resilience and competition**, reducing dependence on a few card networks and large processors.

**Cheaper, faster payments**, particularly cross-border.

**Financial inclusion** for those without bank accounts.

**A response to private alternatives** — stablecoins and large technology firms issuing money-like instruments.

**The objections, which are substantial:**

**Privacy.** A ledger of transactions held by or accessible to a central authority is the dominant public concern. Designers generally propose tiered privacy and intermediated models where the central bank does not see individual transactions, but the concern is about **capability**, not stated intent — and that is not easily answered by design promises.

**Bank disintermediation.** If people moved deposits into CBDC, banks would have less funding for lending. This is why proposals include **holding limits**.

**Programmability.** The theoretical ability to restrict what money can be spent on or make it expire. Central banks have largely disavowed this for retail use; scepticism persists.

**Whether it solves a real problem** that faster domestic payment systems do not already address.

**Status.** Several countries have launched or piloted one; the UK and EU are in design phases with no decision to proceed.

Question 2

What actually happens to your money when you deposit it in a bank?

Accepted Answer

It stops being your money in the physical sense and becomes a debt the bank owes you. Your balance is an entry in the bank's ledger recording what it must repay on demand — not a box of your notes

Question 3

What is a bank run and why do they happen?

Accepted Answer

A bank run is a large number of depositors withdrawing money simultaneously because they fear the bank will fail — and the crucial feature is that the fear can cause the failure regardless of whether

Question 4

What is Open Banking?

Accepted Answer

Open Banking is a regulatory framework requiring banks to let you share your own account data with, or initiate payments through, authorised third parties — securely, and with your explicit consent.

Question 5

What is authorised push payment fraud and am I protected?

Accepted Answer

Authorised push payment (APP) fraud is when you are tricked into sending money yourself to a criminal. Because you authorised the payment, it was historically treated very differently from fraud

Question 6

What is quantitative easing?

Accepted Answer

Quantitative easing (QE) is a central bank creating new money to buy financial assets — overwhelmingly government bonds — in order to stimulate the economy when conventional interest rate cuts have

Question 7

Why do international bank transfers take days?

Accepted Answer

Because there is no single global payment system — money does not move between countries so much as a chain of banks update each other's records, and each link adds time. What actually happens.
