What happened
BlackRock has cut the minimum threshold for in-kind Bitcoin conversions into its iShares Bitcoin Trust (IBIT) from $25 million to $1 million, a 96% reduction. The move lets authorized participants swap Bitcoin directly for IBIT shares instead of settling in cash, making the mechanism accessible well beyond the large market makers and institutional desks it was originally designed for.
Why it matters for the market
Robbie Mitchnick, BlackRock's head of digital assets, said on Bloomberg Television that Bitcoin holders can now use the in-kind route from a $1 million minimum. Previously the higher bar effectively restricted the feature to big trading operations. Lowering it could broaden participation in the ETF's primary market and potentially smooth the link between Bitcoin spot liquidity and ETF share creation.
The update arrives as IBIT has been seeing notable inflows. Over three consecutive days last week, the fund pulled in $479 million, roughly 76% of combined inflows across all U.S. spot Bitcoin ETFs during that stretch. That momentum follows a five-day run of net inflows for the U.S. spot Bitcoin ETF complex in early August, with weekly additions exceeding $750 million.
What traders should watch
From an intraday trading perspective, a lower in-kind conversion threshold may encourage more efficient arbitrage between Bitcoin's spot market and IBIT shares. If authorized participants use the mechanism more often, spreads and price dislocations could narrow, though flows remain sensitive to broader risk appetite and crypto volatility. Traders will likely watch whether the easier conversion route attracts fresh ETF demand or simply shifts how existing positions are structured.
