How do stablecoins make money?
Fiat-backed stablecoin issuers make money almost entirely from interest on the reserves backing the token — the 'float' — while paying holders 0%. At scale this is extremely profitable: Tether reported over $13B in profit for 2024, mostly from Treasury interest on roughly $100B+ of low-cost, non-interest-bearing liabilities.
The float model
When you send an issuer $1 for a stablecoin, they invest that dollar in Treasury bills or bank deposits and keep the interest. You hold a token worth $1 that pays no interest; the issuer earns the risk-free rate on your money for as long as you hold the token. This is the same economic model banks use on non-interest checking accounts, just without deposit insurance or the deposit-taking license.
The scale makes it lucrative: with tens of billions of dollars in circulating supply and short-term rates around 4-5%, issuers earn billions annually just from Treasury interest, with minimal operating costs relative to that income.
Why issuers don't pay yield to holders
Paying interest directly to token holders would likely reclassify the token as a security or deposit-like product in most jurisdictions, triggering banking or securities regulation the issuers have structured to avoid. That's why yield-bearing dollar tokens (tokenized Treasury funds, or yield-sharing designs) are built as distinct, more regulated products rather than being bolted onto USDT or USDC directly.
What happens if rates fall
Issuer profitability is directly tied to short-term interest rates. If the Federal Reserve cuts rates toward zero, as it did in 2020, float income compresses sharply even if circulating supply stays flat. Some smaller issuers with thinner margins would come under real pressure in a sustained low-rate environment; the largest, with the biggest scale advantages, would simply earn less.
Frequently asked
- Do stablecoin issuers charge fees?
- Some charge redemption or minting fees above certain thresholds, but float income from reserve interest dwarfs fee revenue for the major issuers.
- Why doesn't USDT pay interest to holders?
- Paying interest directly would risk the token being classified as a security or bank deposit in many jurisdictions, which issuers have structured to avoid.
- How much profit does Tether make?
- Tether reported over $13B in profit for 2024, driven mainly by Treasury interest income on its reserves.
- Is this different from how a bank makes money?
- Economically similar — both lend out or invest deposited funds and keep the spread — but banks are regulated deposit-takers with insurance schemes; stablecoin issuers generally are not.
