Stablecoin Yields: Where Does the Money Actually Come From?

If You Can't Identify the Yield Source, You Are the Yield

This is the single most important rule in DeFi, and most people ignore it. When a platform offers you 10% APY on your USDC, the first question should always be: where does this money come from? If you can't answer clearly, you're probably the exit liquidity for someone else.

Legitimate Yield Sources

1. Borrowing Demand (3-8% APY)

The most honest yield in DeFi. Traders and investors borrow stablecoins and pay interest. You earn a cut of that interest. Platforms like Aave and Compound facilitate this. The yield fluctuates with market demand — high during bull markets, low during bears.

2. Trading Fee Revenue (2-15% APY)

When you provide liquidity on DEXs, you earn a share of trading fees. This is real revenue from actual economic activity. The catch is impermanent loss, which I've covered in a separate post.

3. Treasury Bill Yield (4-5% APY)

Some protocols invest stablecoin reserves in US Treasury bills and pass the yield to users. This is as "real" as yield gets — the US government is paying interest on its debt. Protocols like Ondo Finance and Mountain Protocol do this transparently.

4. Futures Funding Rates (5-25% APY, variable)

When most traders are long, they pay funding to short sellers. Protocols like Ethena capture this yield through delta-neutral strategies. It's real but highly variable and can go negative.

Red Flag Yield Sources

1. Token Emissions (the "Printer")

Many protocols boost yields by emitting their own governance token. The 50% APY you see is mostly paid in tokens that are being inflated into existence. When you sell these tokens, someone else loses. This is a wealth transfer, not yield creation.

2. Ponzi Mechanics (the "Pyramid")

New deposits paying old depositors. Terra's Anchor was the most famous example. If a protocol's yield can't be traced to real economic activity, it's likely this.

3. "Points" and Airdrop Farming

Not technically yield, but many people park stablecoins hoping for future airdrops. This can be profitable but you're essentially doing unpaid work (providing liquidity/TVL) for a speculative future reward.

My Framework for Evaluating Yields

• Can I trace the yield to a real economic activity? (borrowing, trading, treasury bills)
• Is the yield sustainable at current levels? (20% on stablecoins is almost never sustainable)
• What happens if deposits double? (Sustainable yields decrease with more deposits; Ponzi yields increase to attract them)
• Is the majority of the yield in the stablecoin itself or in a volatile token?

The Bitcoin Comparison

Bitcoin doesn't offer "yield" — and that's a feature. You don't need yield when the asset itself appreciates faster than any sustainable stablecoin yield. Chasing 10% APY on stablecoins while Bitcoin does 50%+ annually over 4-year cycles is a losing trade.
