BlackRock’s IB1T Gains Ground in Europe

IB1T gives investors exposure to Bitcoin through a listed product. It sits within Europe’s exchange-traded product market, where crypto products have traded for years. The product adds BlackRock’s name to a crowded field of Bitcoin ETP issuers.

The fund’s reported holdings of about 14,200 BTC place it among notable European Bitcoin products. Its assets have moved above $1.1 billion since launch. That rise came as more institutions reviewed crypto exposure through regulated market venues.

BlackRock’s move into Europe follows strong demand for spot Bitcoin funds in other markets. The firm has built its crypto strategy across Bitcoin and tokenized assets. However, IB1T remains focused on direct Bitcoin exposure for European investors.

OCC Reserve Cap Draws BlackRock Response

BlackRock also filed a comment letter with the Office of the Comptroller of the Currency. The letter addressed draft rules tied to the GENIUS Act. The firm asked the OCC to remove a proposed 20% cap on tokenized reserve assets.

The proposed limit could affect BlackRock’s BUIDL fund. BUIDL holds nearly $2.6 billion in assets, according to reported RWA.xyz data. The fund supports reserves used by stablecoin projects, including Ethena’s USDtb and Jupiter’s JupUSD.

BlackRock called the proposed cap “extraneous” in its letter. The firm said reserve risk depends on credit quality, duration, and liquidity. It argued that ledger use should not decide whether an asset qualifies.

BUIDL, Stablecoins, and Eligible Reserves

BlackRock also asked the OCC to confirm that Treasury ETFs can count as eligible reserves. The request would cover ETFs that invest only in allowed assets. The firm also pushed for two-year U.S. Treasury floating-rate notes.

These notes reset coupons weekly and usually carry lower price swings. BlackRock said they should fit within permitted reserve assets. Its request links tokenized funds with more traditional Treasury market tools.

The OCC proposal is part of broader rulemaking across several U.S. agencies. The FDIC, Treasury, FinCEN, and OFAC are also working on related rules. Firms face a January 2027 deadline for compliance under the framework.
