Latest backtest update (2026-04): Based on FuNi’s historical rate database (data range 2019-04 to 2026-03, USD pool samples, year-by-year walk-forward windows (2020 to 2026)), our latest backtest shows that the APEX III strategy produced a pre-fee annualized return of roughly 8%–16% over about 180–365 days across the USD and USDT lending markets, and a USD pool average of about 11% after the 15% platform fee, with peaks around 80% (extreme outliers tied to systemic events like LUNA or FTX, not the norm); the baseline ran around 6%–7% long-term. Across the multi-year time windows (2019–2026, seven yearly windows per currency), the APEX III backtest return was higher than the baseline in all seven yearly windows for the USD pool, and in six of seven for USDT. ...

Risk warning: This article is based solely on publicly available information and does not constitute investment advice or any buy/sell signal. Crypto lending involves exchange platform risk, stablecoin de-pegging risk, the risk of prolonged low interest rates, and policy-change risk. There is no such thing as a zero-risk financial product — only commit funds you can afford to lose 100% of. One of the most common questions in Bitfinex lending is: what rate should I actually set? Set it too high and your offer never fills; set it too low and you feel like you left money on the table.
