Stablecoins and bank deposits can look surprisingly similar from a user’s perspective. Both may represent $1, both can be used for payments, and both can sit inside an app rather than as physical cash.
Legally and financially, however, they are very different forms of money.
A bank deposit is a claim on a commercial bank. When $1,000 sits in a checking account, the bank owes the customer $1,000. A stablecoin is generally a digital token issued by a separate private entity and backed by reserve assets intended to keep its value close to a currency such as the U.S. dollar. The IMF describes the distinction as account-based money versus token-based money.
That difference affects everything from deposit insurance to how the money moves.
Bank Deposits Depend on the Bank, Stablecoins Depend on Reserves
Commercial banks do not normally keep every deposited dollar sitting untouched in a vault. Deposits form part of the banking system’s funding base, while banks hold assets including loans, securities and reserves.
Stablecoin issuers use a different model.
For example, Circle says USDC is backed by dollar-denominated reserve assets and can be redeemed 1:1 for U.S. dollars. Its reserves include cash and highly liquid instruments such as short-term Treasuries and overnight Treasury repos.
That reserve structure is also how many stablecoin businesses make money. Instead of paying most of the yield to token holders, issuers can earn income on the securities backing their tokens: a model explored in our breakdown of stablecoin reserves.
Deposit Insurance Is a Major Difference
In the United States, qualifying deposits at an FDIC-insured bank are generally protected up to $250,000 per depositor, per insured bank, per ownership category. The FDIC explicitly says crypto assets themselves are not covered by deposit insurance.
Holding a stablecoin therefore does not provide the same protection as holding money directly in an insured bank account.
Stablecoins introduce different risks, including issuer failure, problems with reserve assets, temporary loss of the dollar peg, blockchain failures and mistakes involving private keys or wallet addresses.
This is one reason why bank stablecoins and tokenized deposits should not be treated as interchangeable. A tokenized deposit may use blockchain technology, but it remains a bank liability rather than becoming a separate reserve-backed token.
