The Hidden Business Behind Stablecoins: It’s All About Treasury Yields

For users across the crypto ecosystem, a stablecoin is merely a safe haven with a guaranteed peg to the dollar. However, the true financial engine of giants like Tether and Circle operates off-chain. The profitability of these issuers does not stem from high transaction fees, but rather from the yield spread generated by holding massive volumes of U.S. sovereign debt.

Market Context: Treasury Bills as the Engine of Revenue

Under the fiat-backed issuance model, maintaining equivalent reserves in highly liquid assets with minimal credit risk is paramount. To fulfill this requirement, companies channel the bulk of their capital into short-term U.S. Treasury bills. These financial instruments combine the immediate convertibility needed to process redemptions with the capacity to accrue consistent institutional interest.

Under this operational dynamic, end token holders receive strict digital liquidity at face value, without directly participating in the underlying yield. Meanwhile, the issuing entities retain 100% of the coupons generated by this multi-billion-dollar collateral. This spread transforms passive reserve portfolios into interest-generating engines, cementing one of the most lucrative operational models in modern finance.
