WisdomTree Short USD Long EUR 3x Daily is a leveraged exchange traded product (ETP) designed to deliver three times the daily inverse performance of the US Dollar (USD) relative to the Euro (EUR). It tracks the MSFX Triple Short US Dollar/Euro Index (TR), employing synthetic replication through unfunded swaps backed by collateral to provide leveraged short exposure to USD via rolling currency forward contracts. Launched in 2011 and domiciled in Jersey, this fully collateralised instrument offers UCITS eligibility, transparent fees with a management fee of around 0.39% to 0.98%, and daily swap adjustments. Structured as a debt security rather than equity, it enables on-exchange trading with liquidity from authorised participants and market makers, without requiring investors to hold derivatives or margin accounts. In currency markets, it plays a key role for tactical positioning on EUR/USD fluctuations, incorporating interest rate differentials while capping losses at the invested amount, subject to market, liquidity, currency, and counterparty risks.
