Where USDT earns the most — safely.

When an exchange pays interest on your USDT, that money has to come from somewhere. The largest source is margin lending: traders borrow USDT to open leveraged positions and pay a borrowing fee for it, and the exchange passes part of that fee to depositors in its flexible-earn or savings products. This is why USDT — the default collateral and quote currency in crypto trading — tends to earn more than smaller stablecoins: borrowing demand for it is constant.

The second source is open lending markets, where exchanges run pooled order books matching lenders and borrowers directly. The third is promotional subsidies: platforms compete for deposits and will pay above-market rates out of their own marketing budget to attract new users or new capital. Subsidized rates are real money, but they are temporary by design.

One honest point that often gets missed: Tether itself earns billions on the Treasury bills backing USDT, but that interest goes to the issuer, not to holders. Holding USDT in a plain wallet earns exactly zero. The yield you see on an exchange is the exchange paying you for the use of your USDT — it is not Tether sharing its reserve income.

Because the main driver is borrowing demand, the rate floats. In bull markets traders pay heavily for leverage and USDT rates climb; in sideways or fearful markets demand dries up and rates compress. A rate you lock in today reflects today's market mood, not a promise about next quarter.

Open our USDT table and you will see rates from roughly 1.4% to 16% on the exact same asset. That spread is not a mistake — it reflects three structural differences between offers.

First, base rates versus promo tiers. A headline like "6% APY" often applies only to the first 200–500 USDT, with everything above that earning a much lower base rate — Binance and Gate both structure their flexible products this way. YieldScope shows the base tier, because that is what your actual balance earns once you deposit more than pocket money.

Second, platform grade. As a rule, the highest rates come from venues that have passed fewer of our checks — newer platforms, lighter regulation, less proof of reserves. The extra yield is compensation for extra risk, not free money. A 14% offer from an unproven venue and a 4% offer from an established one are not the same product at different prices; they are different products.

Third, locked versus flexible. Locking your USDT for 30–120 days typically adds a few percentage points, paid for with the inability to exit. The practical advice: compare rates only within the same risk grade, and treat a big rate gap inside one grade as a question worth answering before you deposit.

Yield on USDT carries three distinct layers of risk, and it helps to keep them separate in your head.

The first and largest is platform risk. When you deposit USDT on an exchange, it stops being your asset and becomes a claim on the platform. If the venue fails — FTX being the defining lesson — depositors stand in line with other creditors, and earn-product balances have no special protection. This risk dwarfs the others in practice: most money lost on stablecoin yield has been lost to failed platforms, not to the stablecoin itself.

The second layer is the peg. USDT has briefly traded below $1 several times in its history, with episodes reaching roughly $0.95 before recovering. The peg has always come back so far, but the underlying question — how solid are Tether's reserves — remains only partially answered: Tether publishes quarterly attestations from BDO, which are snapshots, not a full audit. A holder earning 5% a year has thin margin against even a small permanent depeg.

The third layer is regulatory. The EU's MiCA framework has already pushed regulated European venues to delist or restrict USDT, and similar pressure can appear in other jurisdictions. This usually does not threaten the funds themselves, but it can shrink where you are able to earn on USDT — and forced migrations between platforms have their own costs and risks.
