What lenders are actually earning on Bitfinex margin funding — the volume-weighted median of real trades, not the asking price. These are the exact numbers our engine prices against. Rates are set by borrower demand and are not guaranteed.
Rate spikes are when locking long loans pays best — and they fade within hours. Leave an email and we'll ping you the moment the market crosses your line. Free, no account needed.
Lending on Bitfinex is a queue: offers at a lower rate get borrowed first, and equal rates fill in the order they were placed. This is the actual queue right now — the amount of money waiting at each rate, and how much is ahead of it. Price yourself too high and you wait; too low and you leave yield on the table. This is exactly the trade-off our engine automates.
LendFox lends automatically at the market's going rate, around the clock, and locks in the spikes. Non-custodial — your account, your keys.
Borrower demand for leverage. Traders borrow USD or USDt to open margin positions, and the funding order book matches them with lenders — cheapest offers first. When markets move fast and traders lever up, demand surges and rates spike; in quiet markets rates drift down. No platform sets the rate; supply and demand do.
FRR is a weighted average of loans that are already open, so it reflects the past, not the current market. The rates on this page are volume-weighted medians of recent actual trades — the price at which money is really changing hands right now. In falling markets FRR sits above the traded rate, which is why FRR-pegged offers often sit unfilled.
The headline rates and charts refresh every 5 minutes from live Bitfinex trade data, and the order book below refreshes every 30 seconds. The 30-day history is built from daily volume-weighted medians.
Yes. Bitfinex discontinued its built-in Margin Funding Pro dashboard, leaving lenders who relied on it without an official automation tool. LendFox is an independent, non-custodial replacement: it automates funding offers inside your own Bitfinex account through a funding-only API key, prices from real trade data instead of the lagging FRR, and locks long terms only when the rate is a measured premium. Free during beta.
Lending is secured by borrowers' collateral and margin calls, and lenders don't take market direction risk. You do take exchange counterparty risk — your funds are on Bitfinex — and rate risk, since yields move with demand. Bitfinex also keeps 15% of earned interest as its fee. Never lend money you can't afford to keep on an exchange.
