The spreads
Two gaps say more about this market than any single rate: what you pay for someone else to hold your Bitcoin, and what borrowing against Bitcoin costs over the risk-free rate. The first is wide for structural reasons rather than pricing ones, which we set out in CeFi vs DeFi Bitcoin loans.

On-chain depth · collected history
Market-wide daily totals across every on-chain protocol we track, not just this day.
TVL is total supplied across every tracked market, with pools listed under more than one collateral type counted once. Utilization is total borrowed divided by total supplied, which weights each pool by its own size rather than averaging protocols equally. Both series are also available in the CSV and JSON feeds.
Common questions
Answered from this day's figures, so an archived page stays accurate.
What is the BoB Bitcoin Rate Index?
It is a single blended rate for borrowing against Bitcoin, published daily. On 4 August 2026 it stood at 10.42% APR. It combines two indices we publish separately on this page: the custodial (CeFi) index at 10.42%, an average of the effective APR charged by 6 US-available lenders, and the on-chain (DeFi) index at n/a, a TVL-weighted average of variable USDC borrow rates across 0 Bitcoin-collateral protocols. Both components are shown above the blend so anyone can check the arithmetic or re-weight it themselves.
Why are on-chain Bitcoin loan rates so much lower than custodial ones?
On 4 August 2026 the gap was wide (custodial 10.42% against on-chain n/a), and it is structural rather than a pricing anomaly. A custodial lender underwrites you, runs KYC, arranges custody of your Bitcoin, lends you actual dollars, and usually gives you a fixed rate and a window to cure a margin call. An on-chain protocol does none of that: your Bitcoin is wrapped into a token a smart contract can hold, you receive a stablecoin rather than dollars, liquidation is automatic with no grace period, and the rate is variable and reset continuously by supply and demand with no ceiling. The lower number buys you less protection, and it is a snapshot rather than a quote.
What loan size and LTV are the custodial rates quoted at?
A reference loan set by the running average size and loan-to-value of the real loan enquiries submitted to borrowonbitcoin.com to date, rather than a round number we picked. Each enquiry's LTV is fixed at the Bitcoin price on the day it was made, so past figures do not rewrite themselves when the market moves, and a page for a given day uses the pool as it stood the night before, so a published figure is settled for the whole of that day.
Are these rates fixed or variable?
The custodial rates are the lenders’ own published terms and are typically fixed for the loan term, and they are effective APRs with origination fees included rather than headline interest rates. The on-chain rates are variable by design: they are read from the protocols and change continuously, so the figure here is what the rate was at the daily snapshot and not a rate you can lock in.
How does this compare to borrowing without Bitcoin collateral?
On 4 August 2026 the index sat 6.34 points above the 1-year US Treasury at 4.08%. The benchmark table on this page carries the wider context: the Fed funds target range, SOFR, the 3-month, 1-year and 10-year Treasury, the prime rate, and both Freddie Mac mortgage rates, each with its own publication date.
How current is this page, and where do the numbers come from?
The snapshot is taken daily at 14:00 UTC. Custodial rates are verified against each lender’s own published terms; on-chain rates are read from the protocols; benchmark rates come from their original publishers and arrive on different calendars, which is why each row carries its own date. The blend weights come from Galaxy Research’s quarterly measurement of open crypto-collateralised borrows and are held fixed between releases. Change columns on this page compare against 3 August 2026.

Methodology. With no DeFi rate available today, the index reports the CeFi index alone.
Reference loan.The CeFi index is priced at the mean loan size and mean LTV of real loan enquiries submitted to borrowonbitcoin.com to date. This is our own first-party data: the reference loan is set by what people actually came here to borrow, not by a round number we chose. Each submission's LTV is fixed at the Bitcoin price when it was made, so past values do not move when the market does.
Sources. Published by borrow/on/bitcoin, a Sypher Capital publication. Inputs: sleeve weights from Galaxy Research, The State of Crypto Leverage Q1 2026. Custodial rates verified daily against each lender's published terms; on-chain rates read from protocol contracts. Benchmark rates are published by Federal Reserve, New York Fed, US Treasury, WSJ survey and Freddie Mac, and redistributed by FRED.
