Observability	price: partial — Published margin schedule, benchmark plus tier spread, and therefore reconstructible to depth from the benchmark series plus archived card snapshots (D31) rather than requiring dense capture. Sourced 2026-08-07 from interactivebrokers.com/en/trading/margin-rates.php: IBKR Pro USD tiers 0-100,000 at 5.130% (BM + 1.5%), 100,000-1,000,000 at 4.630% (BM + 1%), 1,000,000-50,000,000 at 4.380% (BM + 0.75%); IBKR Lite 6.130% (BM + 2.5%) across those tiers. NOT YET INGESTED. The rate is the broker general margin schedule and is NOT bitcoin-specific: the same debit balance is charged the same whether the collateral is a BTC ETP or any other marginable security. What IS bitcoin-specific is the collateral - whether the ETP is marginable and at what maintenance requirement. Publishing this as a "BTC borrow rate" without that sentence would imply a product that does not exist. quantity: partial — Market-level only: FINRA publishes monthly aggregate margin debt for the US brokerage industry. Security-level margin debt against any individual BTC ETP is not published by FINRA, the broker or the issuer, so the share of that aggregate financed against bitcoin exposure is unobtainable and is declared rather than estimated (spec section 8.1). composition: none — Loan-level composition is unobtainable in the posted class everywhere (section 8.1), and a broker publishes no breakdown of what collateral secures its margin book. The collateral is etp_share, which is economically bitcoin and legally a security; a holder can never redeem shares for coins, so this is a claim on a trust rather than on the coins (section 6.1, D31).
