Who’s on the Other Side?
Every lender needs a borrower.
It sounds obvious, but most depositors never ask the question. They see a yield, they see a vault, they deposit. The number goes up. Who cares where it comes from?
You should care. Because the answer tells you whether the yield is real.
Yield has a source
DeFi yield comes from somewhere. It’s not magic. Someone is paying for it.
In lending, that someone is a borrower. They’re taking your capital, paying you interest, and doing something with it that they believe will earn more than the cost of borrowing.
If you don’t know what that something is, you don’t understand your risk.
The borrower’s trade
Different collateral types attract different borrowers with different strategies.
A borrower posting ETH to borrow stablecoins might be leveraging long. They believe ETH will go up, so they borrow dollars against it instead of selling.
A borrower posting a yield-bearing token might be looping. They deposit, borrow, redeposit, borrow again — stacking yield on top of yield until the spread compresses or liquidation risk gets uncomfortable.
A borrower posting RWA collateral might be financing real economic activity. Trade finance, working capital, inventory. They need liquidity now and they’ll pay for it.
Each of these has a different risk profile. Each tells you something different about where your yield comes from.
Leverage borrowers
The classic DeFi borrower is someone who wants leverage without selling.
They hold an asset. They believe it will appreciate. Instead of selling to access liquidity, they borrow against it. If the asset goes up, they win twice — appreciation plus whatever they did with the borrowed funds.
The risk: if the asset drops, they get liquidated. Your principal is protected by the collateral buffer, but utilization spikes when markets move. Everyone wants out at the same time.
This borrower is procyclical. They borrow more in bull markets, less in bear markets. Yield follows sentiment.
Loop borrowers
The more sophisticated DeFi borrower is running a loop.
They find a spread between borrowing cost and yield. They deposit a yield-bearing asset, borrow against it, use the borrowed funds to get more of the yield-bearing asset, deposit that, borrow again.
Each loop amplifies their exposure. If the yield-bearing asset pays 8% and borrowing costs 5%, the spread is 3%. Loop it three times and now you’re earning 9% on your original capital.
The risk: loops unwind violently. If the yield-bearing asset depegs, drops in value, or if borrowing costs spike, the whole structure collapses at once. Liquidations cascade.
This borrower is fragile. The strategy works until it doesn’t.
Real economy borrowers
The newest DeFi borrower is financing something offchain.
Trade finance. A company needs to pay a supplier today and will receive payment from a customer in 60 days. They borrow onchain to bridge the gap.
Working capital. A business has receivables that haven’t converted to cash yet. They tokenize them, post them as collateral, borrow against them.
Arbitrage. A desk sees a price discrepancy across markets. They need capital to capture it. They borrow, execute, repay.
These borrowers are doing something with the money that generates return regardless of crypto market conditions. The yield source is disconnected from token prices.
The risk: credit risk, operational risk, counterparty risk. These are real businesses that can fail. The collateral is only as good as the underlying economic activity.
This borrower is countercyclical. They borrow based on real-world opportunities, not crypto sentiment.
Why it matters
The borrower profile tells you about yield sustainability.
Leverage borrowers pay more when markets are hot, less when markets are cold. Your yield follows the cycle.
Loop borrowers pay consistent spreads until they don’t. Your yield is stable until it collapses.
Real economy borrowers pay based on the cost of capital in their business. Your yield is tied to economic activity, not crypto speculation.
None of these is inherently better. But they’re different. And knowing the difference helps you understand what you actually own.
The curator’s job
This is where curation matters.
A curator who understands who’s on the other side can build vaults that match depositor expectations. High yield from leverage borrowers for those who want cycle exposure. Stable yield from real economy borrowers for those who want consistency.
The mistake is mixing them without knowing it. Promising stable yield backed by loop borrowers. Promising high yield backed by conservative RWA.
The collateral tells part of the story. The borrower tells the rest.
The bottom line
Yield has a source. That source is a borrower.
Before you deposit, ask: who’s on the other side? What are they doing with the capital? Why are they willing to pay this rate?
If you can’t answer those questions, you don’t understand your risk. And if you don’t understand your risk, you can’t price it.
