BlackRock urges OCC to remove 20% cap on tokenized reserves — BUIDL Fund holds $2.6B
BlackRock submitted a 17-page comment letter urging the OCC to eliminate the proposed 20% cap on tokenized reserve assets — arguing that reserve risk should be evaluated on credit quality and liquidity, not on whether assets are held on distributed ledger infrastructure. The GENIUS Act July 18 deadline makes MCI reserve compliance the most urgent infrastructure requirement of 2026.
→ Source: Finance Feeds, May 3, 2026Intro Paragraph:
mcireserve is the reserve identity built for the regulatory standard that the GENIUS Act, BIS FSI Paper No. 27, and BlackRock’s $2.6 billion BUIDL Fund collectively define as the most urgent MCI compliance requirement of 2026.
Multifunction Cryptoasset Intermediaries that accept customer assets, fund lending activities, and manage financial intermediation must demonstrate reserve adequacy that meets BIS prudential standards — the same standards that traditional banks must satisfy but that MCIs have historically operated without.
mcireserve.com/.eth is the Convergence Identity for the institutional infrastructure that documents, verifies, and manages MCI reserve compliance — the namespace that connects BIS prudential reserve requirements with GENIUS Act reserve asset standards and OCC capital treatment guidance in a single institutional-grade identity.
With the GENIUS Act deadline of July 18, 2026 now 57 days away, every MCI managing reserve assets must establish its reserve compliance identity before the first OCC examination cycle begins.
Pillar 1 — Regulation
The BIS FSI Occasional Paper No. 27 (April 23, 2026) identified inadequate reserve management as the primary systemic vulnerability of Multifunction Cryptoasset Intermediaries — institutions that accept customer assets through earn programmes create deposit-like liabilities without the reserve requirements, insurance protection, or central bank backstop that apply to regulated banks.
The paper explicitly cited the Celsius Network and FTX collapses as direct consequences of unmanaged MCI reserve risk.
The FDIC GENIUS Act Proposed Rule (April 7, 2026) establishes 1:1 reserve backing requirements for PPSIs — with permitted reserve assets including US Treasury bills, central bank reserves, and insured bank deposits.
The BlackRock OCC Comment Letter (May 3, 2026) challenged the proposed 20% cap on tokenized reserve assets — demonstrating that the reserve asset debate is the central compliance question for every MCI and PPSI in 2026.
The FRB, OCC, and FDIC Joint FAQ (March 5, 2026) confirmed technology-neutral capital treatment for tokenized reserve assets — creating the regulatory foundation for MCI reserve management that operates across both traditional and distributed ledger infrastructure. Together these four regulatory events define the MCI reserve standard that mcireserve.com/.eth holds the namespace for.
Pillar 2 — The Problem Solved
Every Multifunction Cryptoasset Intermediary managing reserve assets faces the same institutional challenge: how does it demonstrate to the OCC, FDIC, and BIS that its reserve composition, liquidity profile, and custody arrangements meet the prudential standards for MCI reserve compliance — and does it own that identity in both Web2 and Web3?
mcireserve.com is the institutional answer — the compliance portal, the reserve management brand, and the legal identity for any MCI that must document its reserve adequacy under the BIS prudential framework and GENIUS Act reserve standards. mcireserve.eth is the on-chain complement — an ENS-resolvable endpoint where reserve attestations, asset composition records, and liquidity documentation can be stored as immutable distributed ledger entries.
The BIS paper identified the absence of deposit insurance and inadequate reserve safeguards as core MCI vulnerabilities — every MCI that seeks to participate in the institutional financial system must now demonstrate reserve adequacy that matches or exceeds traditional banking standards. The BlackRock challenge to the OCC 20% cap demonstrates that the reserve asset debate will define the regulatory landscape for MCIs through 2026 and 2027.
No existing domain combines the BIS MCI framework with institutional reserve compliance infrastructure as directly and institutionally as mcireserve.
Pillar 3 — System Integration
mcireserve is the reserve compliance core of the PillarsX Multifunction Cryptoasset Intermediary namespace. It connects directly to  mcitreasury.com/.eth — the Treasury asset identity for the primary reserve asset class under the GENIUS Act — and to  mcitbills.com/.eth as the T-Bills identity for the short-duration instruments that form the most liquid reserve asset category.
Beyond the MCI cluster, mcireserve integrates with  permittedreserves.com/.eth as the OCC permitted reserve asset standard that defines which assets qualify for MCI reserve backing,  unifiedreserves.com as the unified reserve standard that connects MCI reserve operations across the BIS Unified Ledger architecture, and  verifiablereserves.com/.eth as the on-chain verification standard that produces cryptographic proof of reserve adequacy.
An institution acquiring mcireserve.com/.eth secures the namespace for the most regulatorily consequential MCI compliance category — the one that determines whether every MCI can demonstrate the reserve adequacy that the BIS, OCC, and FDIC require before the GENIUS Act deadline of July 18, 2026.
