Stablecoin vs CBDC: who stands behind the digital money?
A stablecoin and a central bank digital currency can both look like "a digital dollar" on a screen. The difference is who promises it's worth a dollar, and what happens if that promise is tested.
The short answer
A Stablecoin is a crypto token issued by a private company. It aims to stay worth one unit of a currency, usually $1, often by holding cash and short-term government bonds as reserves.
A CBDC (central bank digital currency) is digital money issued by a central bank itself. It's a direct claim on the central bank, like cash in digital form.
Side by side
| Stablecoin | CBDC | |
|---|---|---|
| Issued by | A private company | A central bank |
| What it's a claim on | The issuer and its reserves | The central bank |
| Runs on | Public blockchains, mostly | Whatever system the central bank builds |
| Who can hold it | Anyone with a crypto wallet, often | Set by the central bank's rules |
| How it can fail | Reserves short, a run, a hack, a broken design | Mainly policy and privacy questions, not default |
| Privacy | Transactions are often public on the chain | Depends on design; a common public worry |
| Examples | USDT (Tether), USDC (Circle) | Bahamas Sand Dollar, Nigeria's eNaira, China's e-CNY pilots |
| US status (Oct 2026) | Federal rules for payment stablecoins under the GENIUS Act, signed July 2025 | A January 2025 executive order bars federal agencies from creating one |
How a stablecoin keeps its price
The common design is simple. For every token, the issuer says it holds about one dollar in reserves. Big traders can usually swap tokens for dollars with the issuer, and that swap pulls the price back toward $1.
When that works, the price barely moves. When people doubt the reserves, they rush to sell, and the price can slip below $1. That's called a de-peg.
When stablecoins broke
- TerraUSD, May 2022. An "algorithmic" stablecoin that relied on a sister token instead of cash reserves. It collapsed, and tens of billions of dollars in value disappeared within days.
- USDC, March 2023. Part of its reserves sat at Silicon Valley Bank when the bank failed. USDC briefly fell well below $1, then recovered once the deposits were made safe.
The lesson: a stablecoin is only as solid as what's behind it and who can check it.
How a CBDC works
A CBDC would be issued and backed by the central bank directly. It can't run out of reserves the way a company can, because the central bank creates the currency.
Most of the debate is about design: privacy, whether it pays interest, how much one person can hold, and whether it would pull deposits out of banks.
Status as of October 2026:
- Bahamas: the Sand Dollar launched in 2020.
- Nigeria: the eNaira launched in 2021.
- China: the e-CNY has been in large pilots for years.
- Euro area: the ECB moved its digital euro project into its next phase in October 2025. It says a first issuance could come in 2029 if EU law is adopted.
- United States: no CBDC, and a 2025 executive order bars federal agencies from creating one.
Never treat a stablecoin like a bank deposit. In the US, a stablecoin isn't government-insured. If the issuer or the platform holding it fails, getting your money back can be slow or partial.
Which fits you?
This isn't a buy decision. It's about knowing what you hold:
- Using stablecoins to move between crypto trades: check which issuer, what backs it, and where you hold it. See how to buy crypto safely.
- Holding stablecoins for a long time: remember the de-peg risk and the platform risk.
- Curious about CBDCs: they're mostly a policy topic for now. Watch central bank announcements, not social media.
Common mistakes
- Assuming $1 is guaranteed. Stablecoins aim for $1. They have broken before.
- Trusting high-yield offers on stablecoins. A high "interest" rate means someone is taking risk with your coins. See crypto scams to avoid.
- Sending to the wrong network. The same token can exist on several blockchains. Pick the wrong one and funds can be lost.
- Confusing a CBDC with crypto. A CBDC is government money in digital form. It isn't decentralised.
Questions
What is the difference between a stablecoin and a CBDC?
A stablecoin is issued by a private company and backed by its reserves. A CBDC is issued by a central bank and is a direct claim on it. Both aim to be worth one unit of a currency.
Does the US have a CBDC?
No. A January 2025 executive order bars federal agencies from establishing a central bank digital currency. US stablecoins are covered by the GENIUS Act, signed in July 2025.
Can a stablecoin lose its peg?
Yes. TerraUSD collapsed in May 2022, and USDC briefly fell well below $1 in March 2023 when a bank holding part of its reserves failed. Reserve quality and transparency matter.
Is the digital euro coming?
The ECB moved the project into its next phase in October 2025 and says a first issuance could happen in 2029, but only if EU legislation is adopted first.
