Reading Bitfinex funding-rate trends: sources and measurement
Funding-rate analysis starts by separating offers, fills and credited interest. This guide explains how to compare observable data without treating quotes as account returns.
Correction to the earlier article
This URL previously contained a 2026 Q1 review. Its quarterly ranges, time-of-day percentages and return multipliers lacked reproducible sources and have been removed. This article does not claim to validate actual Q1 statistics.
Three different measurements
| Data | What it shows | What it does not establish |
|---|---|---|
| Order-book quotes | Conditions requested at that moment | A rate every lender can obtain |
| Executed rates | Terms of particular fills | Whole-account annual net returns |
| Credited interest | Recorded income for a period | Future rates or income |
Peak quotes, volume-weighted rates and medians can differ substantially. Compare the same currency, timezone, fee treatment and sampling method across periods.
Keep a reproducible observation log
Record source, retrieval time, period boundaries, missing intervals, rate units and fee treatment. Decide whether hourly samples form a time average or a volume-weighted measure. Do not fill no-trade intervals with invented execution rates.
Changes in supply and duration can be informative, but a BTC price rise does not prove every funding asset’s demand must rise with it.
Before publishing a quarterly report
Provide complete period coverage, traceable data, formulas and missing-data disclosure. A single account describes that account, not the entire market or all customers. Use the report methodology before drawing performance conclusions.
