What it is
One cycle, starting from an asset that earns yield:- Supply the asset as collateral.
- Borrow a stablecoin against it.
- Swap the borrowed stablecoin back into the first asset.
- Supply the proceeds as additional collateral.
Mechanics on AGI3
- The loop is built by hand from supply, borrow, and swap. Each leg is its own transaction with its own network fee, and the swap leg’s price impact recurs every cycle.
- Each cycle is bounded by the market’s max borrowable LTV, so the amounts shrink geometrically. At the 80% max LTV of a blue-chip market, the theoretical ceiling on total exposure is 5× your starting capital.
- The ceiling is unreachable in practice. The 3% safety margin trims every borrow, swap costs consume part of each cycle, and approaching the ceiling drives the health factor to 1.00 and then below it. The last cycles add little exposure and most of the fragility.
When it fits
Conviction in a yield-bearing asset, a spread wide enough to survive the per-cycle costs, and a mandate that tolerates leveraged single-asset exposure with no automated backstop. Looping is a leveraged position in a single asset; size it as you would size any leveraged single-asset trade.What it costs
- Swap fees and price impact on every cycle, compounding across the loop.
- The floating borrow rate on the full recursive debt.
- Network fees on every leg, several legs per cycle, in both directions: the exit repeats the legs in reverse.
How it fails
- The health factor compresses with every cycle, and this is the defining risk. A single position at half its ceiling absorbs a price move that liquidates a looped book sitting near the maximum.
- Losses are leveraged too. At 5× exposure, a 10% fall in the collateral is a 50% loss of equity, before liquidation penalties.
- The spread inverts. Both rates float, and if the borrow cost rises above the collateral’s yield, the loop bleeds at leveraged scale; the mechanics are the yield spread’s inversion, multiplied.
- Concentration earns no credit. Looping concentrates the book in one asset by construction; the portfolio health score scores that near zero on concentration, and its crash-day scenario shocks every derivative of an asset together, because wrappers of the same asset do not diversify.
- Unwinding is not symmetrical. The loop is built at leisure in calm markets, while unwinding means repaying debt to release collateral, which can mean swapping at exactly the moment spreads widen and liquidity thins. The exit is slower and more expensive than the entry, and there is no automated unwind to fall back on.
- A depeg breaks the premise. Looping a derivative against its underlying assumes the two track each other; if that relationship breaks, LTV moves sharply with no move in the underlying at all.
