# Synthetic dollars: a dollar target built from positions A synthetic dollar targets dollar value through a portfolio or trading strategy rather than only a cash reserve. A common mechanism pairs an asset with a short derivative to offset price changes. The hedge can reduce directional exposure while leaving funding, execution, custody, exchange and liquidation risks.

([Ethena Overview](https://docs.ethena.fi/)) - **Funding:** A perpetual-futures hedge can receive or pay funding. ([Funding Risk](https://docs.ethena.fi/protocol-overview/risks/funding-risk)) - **Scope:** A synthetic-dollar token and its savings wrapper are distinct products. ([Ethena Overview](https://docs.ethena.fi/)) ## A simple hedge, with the assumptions visible Suppose a portfolio holds one asset worth $100 and a short derivative covering one unit. If the asset price rises to $110, the asset gains $10 while the short loses approximately $10. If it falls to $90, the asset loses $10 while the short gains approximately $10. Ignoring costs and margin mechanics, the combined value remains near $100. The example assumes an exact hedge, matched prices and a counterparty that pays what it owes. Real positions can differ in settlement asset, margin requirements, expiry and liquidity. Dollar exposure is a property of the whole portfolio, not of the asset held on one side. Evidence: [Ethena Overview](https://docs.ethena.fi/) ## A hedge is not a guaranteed income stream Perpetual contracts exchange funding payments to connect derivative prices to spot markets. Depending on the sign of the rate, a short position may receive funding or have to pay it. Holding a short therefore does not lock in a permanent positive yield. Ethena’s funding-risk documentation describes a reserve buffer and changing allocations as mitigations. Those are responses to a cost that can persist; they do not remove the underlying obligation. Historical averages should not be presented as a promised future rate. Evidence: [Funding Risk](https://docs.ethena.fi/protocol-overview/risks/funding-risk) ## Read the actual portfolio, not only the original design Ethena’s documentation accessed on 2 October 2026 describes USDe alongside its separate sUSDe savings product and multiple backing strategies, including basis trades, lending and real-world assets. It also distinguishes open-market acquisition from direct minting and redemption for approved counterparties. This is a description of that documentation, not an independently verified portfolio valuation. A complete review must follow where positions are held, how collateral is controlled and how proceeds become available during exchange stress. Off-chain custody and derivatives can remain essential even when the token itself moves on a public blockchain. The current allocation and terms must be checked separately from this mechanism lesson.

No. It describes offsetting sensitivity to an underlying price. It does not settle funding, custody, basis, liquidation or counterparty risk.

No. Ethena identifies USDe as its synthetic dollar and sUSDe as a separate savings asset with its own access and reward mechanics.
