Bitfinex FRR vs fixed funding rates
FRR and fixed offers can show nearly identical APRs when you place them, yet behave very differently after they fill. The useful question is not which rate is universally better. It is whether you want the contract to follow the market or preserve the rate that was matched.
The choice is about repricing
Bitfinex describes the Flash Return Rate (FRR) as an amount-weighted average of active fixed-rate funding. It updates once per hour. A funding contract at FRR therefore moves with that benchmark instead of preserving one daily rate for its whole life.
A fixed-rate contract keeps the agreed rate after matching. That can protect a lender when rates fall, but it can also leave the lender below market when rates rise. Neither option guarantees a fill, a duration, or a return.
FRR, FRR Delta and fixed offers
FRR: the rate follows the hourly benchmark after matching. This removes manual repricing inside the contract, but exposes income to every downward FRR move as well as every upward move.
FRR Delta: Bitfinex supports a variable form that keeps an offset to FRR and a fixed form that follows FRR while the offer rests, then becomes static when matched. The latter separates queue pricing from contract pricing.
Fixed: you choose a daily rate and maximum period. The offer must still meet compatible borrower demand. Once taken, the provider cannot recall it; the borrower may return it before the maximum period ends.
What changes for the lender
FRR is updated once per hour, so its displayed APR is a moving snapshot rather than a promised annual return.
A fixed contract preserves its matched daily rate until the funding is returned or reaches its maximum term.
The selected period is a maximum. It controls compatibility and exposure, but the borrower may return funds early.
Compare net interest after Bitfinex’s standard funding fee, and include idle time between contracts.
A practical decision framework
Use live market context and your own constraints rather than treating one order type as a permanent winner:
- Prefer FRR when tracking the market matters more than locking today’s rate and you accept hourly income changes.
- Prefer fixed when the current rate is high relative to its history and preserving that matched rate justifies waiting for a compatible borrower.
- Consider FRR Delta Fixed when you want an offer to stay relative to FRR while waiting, but become fixed after execution.
- Measure realized results: net rate, actual funded seconds, early returns and idle time. Headline APR alone cannot compare the choices.
FRR vs fixed FAQ
Is FRR always better than a fixed rate?
No. FRR benefits when the benchmark rises and loses income when it falls. A fixed contract does the opposite: it preserves the matched rate in either direction.
Can I close fixed funding before the selected period ends?
Not as the provider after it has been taken. Bitfinex states that the borrower may return it early, or the system returns it when the maximum period expires.
Does an FRR offer fill faster?
Not automatically. Fill timing still depends on borrower demand, period compatibility, available supply and queue position. Inspect the live book before choosing.
Compare the market before placing an offer
Use the live funding book for current FRR, fixed bids, asks and queue depth, then compare the rate with three years of history.
