Synthetic Dollar
A dollar-pegged asset that maintains its peg through a derivatives-based hedging strategy, such as a delta-neutral position, rather than through direct fiat or crypto collateral reserves.
A synthetic dollar is a dollar-pegged asset that maintains its peg through an active derivatives-based hedging strategy rather than simply holding fiat currency or crypto collateral in reserve the way a traditional algorithmic stablecoin (see Kaavon's "Algorithmic Stablecoin" glossary definition) or fiat-collateralized stablecoin does. A common approach holds a long spot position in a crypto asset while simultaneously holding an offsetting short position in that same asset's perpetual swap (see Kaavon's "Perpetual Swap" glossary definition) market, constructing a delta-neutral position whose combined value stays roughly stable in dollar terms regardless of the underlying asset's own price movement.
Yield for a synthetic dollar's holders is typically generated from the funding rate (see Kaavon's "Funding Rate" glossary definition) earned by holding the short perpetual position, plus any staking yield on the underlying spot collateral, which can make synthetic dollar yield attractive during periods of persistently positive funding rates but can turn negative during periods of sustained negative funding, distinguishing its risk profile sharply from a simple fiat-collateralized stablecoin. Because a synthetic dollar's stability depends on the hedging strategy and derivatives market functioning correctly rather than on holding directly redeemable collateral, it carries a meaningfully different, more complex risk profile than a traditional collateral-backed stablecoin.
Examples
- A synthetic dollar might maintain its peg by holding a long spot position in an asset alongside an offsetting short perpetual swap position, rather than holding directly redeemable fiat or crypto reserves.
- A synthetic dollar's yield, often derived from perpetual swap funding rates, can turn negative during periods of sustained negative funding, unlike a traditional fiat-collateralized stablecoin's more predictable backing.
