Synthetic Replication
Synthetic replication is the practice of creating an investment position that mimics the performance of an underlying asset using a combination of other financial instruments. Instead of holding the asset directly, a trader uses derivatives such as options, futures, or swaps to achieve the same risk and return profile.
This is often done to bypass liquidity constraints, reduce transaction costs, or gain exposure to assets that are difficult to hold physically. In decentralized finance, synthetic assets are created by locking collateral into smart contracts to issue tokens that track the price of real-world assets.
The No Arbitrage Principle dictates that the price of this synthetic position must remain linked to the underlying asset, otherwise, traders will profit from the difference. This process relies heavily on automated oracles and liquidation mechanisms to maintain the peg.
It allows for the democratization of access to various markets without requiring direct ownership of the underlying assets.
