BlackRock has lowered the minimum bitcoin swap threshold for its iShares Bitcoin Trust (IBIT) to $1 million from $25 million, a reduction disclosed in the fund’s regulatory filings that governs how large in-kind bitcoin transactions with authorized participants can be. The change to the IBIT minimum bitcoin swap threshold narrows the entry point for these creation and redemption transactions, the mechanism through which the spot bitcoin ETF gains or sheds underlying BTC.
What Changed in BlackRock’s IBIT Bitcoin Swap Threshold
The core change is numeric: the floor for an IBIT in-kind bitcoin swap moved down to $1 million, a twenty-fivefold reduction from the prior threshold. The revision appears in IBIT’s ongoing disclosures filed with the U.S. Securities and Exchange Commission, including the trust’s quarterly filing.

These swaps are the in-kind creation and redemption transactions between the trust and its authorized participants, settled in bitcoin rather than cash. The earlier $25 million minimum was described in IBIT’s prior registration materials filed with the SEC, among the trust’s 2025 prospectus supplements.
Why the Lower Threshold Matters for IBIT and Bitcoin Market Watchers
A lower minimum threshold can signal a change in transaction accessibility or operational flexibility for the parties that create and redeem IBIT shares. It does not, on its own, indicate a change in fund flows, and the filing does not attach any price or demand projection to the revision.
The move draws attention because it comes from BlackRock’s IBIT, the largest spot bitcoin ETF by assets and a vehicle that has repeatedly dominated daily bitcoin ETF inflows. Earlier reporting also described BlackRock executing large bitcoin-to-ETF swaps through the same in-kind machinery that this threshold governs.
For bitcoin-focused readers, the practical reading is measured: a smaller minimum ticket size widens who can participate in an individual in-kind swap, without confirming any effect on liquidity, spreads, or net creation activity. Those outcomes are not stated in the filing and should not be inferred as established.
What to Watch After the Threshold Cut
The next signal is whether subsequent IBIT disclosures report changed creation and redemption activity following the lower threshold. IBIT’s filing history is indexed through the SEC’s EDGAR system, on the trust’s filings page.
Readers can also watch aggregate flow data, given IBIT’s outsized role in weeks when spot bitcoin ETFs have added hundreds of millions in a single session and stretches when the funds pulled close to $2 billion in a week. Whether the threshold change coincides with any shift in that pattern will only be visible in later filings and flow reports.
Beneath the ETF wrapper, the asset itself continues to be governed by bitcoin’s fixed monetary schedule: a supply issuance that halves roughly every four years and a difficulty adjustment that retargets block production about every two weeks. Those network fundamentals set the terms for the BTC that any IBIT swap, at $1 million or the old level, ultimately settles in.
