Why do stablecoin yields beat bank savings rates?
Most of the gap is a bank keeping a spread for itself: your savings account pays you a fraction of what the bank earns lending out or investing your deposit, while a tokenized Treasury fund or a well-collateralised lending pool passes closer to the full market rate through to you. The rest of the gap — anything meaningfully above the T-bill rate — is compensation for credit, liquidity or smart-contract risk your bank account doesn't carry.
The spread a bank keeps
A bank takes your deposit, pays you a small rate, and lends or invests the money at a much higher one — that spread is the bank's core business model, and regulation, branch networks and deposit insurance all cost money that comes out of your rate. A tokenized Treasury fund or a direct T-bill exposure has far fewer intermediaries taking a cut, so more of the underlying market rate reaches you.
This is why 'safe' stablecoin-adjacent yield (a tokenized T-bill fund) tends to land close to the actual T-bill rate, while a bank easy-access savings account often pays meaningfully less than that same benchmark.
The part that isn't just 'cutting out the bank'
Any yield meaningfully above the T-bill benchmark is not simply disintermediation — it is payment for a specific additional risk: borrower default and liquidation risk in a lending pool, funding-rate risk in a delta-neutral synthetic, or smart-contract risk in the protocol itself. None of that is insured the way a bank deposit up to the local guarantee limit is.
- Rate near the T-bill yield: mostly disintermediation, low incremental risk
- Rate meaningfully above T-bills: priced-in credit, funding or contract risk
- Bank savings rate below T-bills: the bank's spread, plus deposit insurance you're paying for
Frequently asked
- So is stablecoin yield actually safer or riskier than a bank account?
- Below the deposit insurance limit, an insured bank account is generally safer. Above it, a Treasury-backed tokenized fund and an uninsured bank balance are both credit exposures — just to different entities.
- Why do some stablecoin yields look absurdly high?
- Very high advertised APYs are usually funded by token emissions, not real cash flow, and the token can fall in value faster than the yield accrues — check the source before comparing headline numbers.
