mcitbills.com & .eth | MCI T-Bills Identity
MiCA's full enforcement from 1 July 2026 establishes strict reserve composition standards: ARTs must hold at least 30% of reserves in segregated accounts at regulated credit institutions, rising to 60% for significant tokens; EMTs must maintain 100% reserves in similar accounts, with EBA-approved quarterly audits. US Treasury bills and notes are among the primary reserve-eligible instruments under both MiCA and GENIUS Act frameworks. DTCC begins limited production trades of tokenized US Treasuries in July 2026 under SEC No-Action Letter authorization — the highest-custodial-scale Treasury tokenization deployment to date. The convergence of MiCA reserve mandates and DTCC's tokenized Treasury infrastructure defines the institutional environment in which the mcitbills namespace operates — the identity layer for MCI Treasury bill reserve and settlement infrastructure under simultaneous EU and US regulatory enforcement.

Fidelity's FYMXX explicitly caps T-Bill holdings at 93-day maturity — the fourth major asset manager fund to operationalize the exact statutory eligibility window mcitbills anchors
Fidelity's Reserves Digital Fund (FYMXX), launched June 15, 2026, invests exclusively in Treasury bills, notes, and bonds with remaining maturities of up to 93 days — the precise statutory threshold the GENIUS Act establishes for direct T-Bill holdings as permitted reserve assets. This follows BlackRock and State Street/Anchorage Digital's parallel fund launches built around the same 93-day window, confirming that the eligibility standard mcitbills documents is now the operative product specification across at least four major institutional fund managers competing for stablecoin issuer reserve mandates. mcitbills.com & .eth anchors the namespace for this 93-day eligibility standard as the institutional fund ecosystem around it consolidates further.

OCC GENIUS Act Final Rules 37 days — T-Bills reserve backing becomes binding statutory requirement as DTCC tokenized T-Bills infrastructure launches H2 2026 for 50+ institutional participants
The OCC and FDIC GENIUS Act Final Rules deadline is July 18, 2026 — 37 days from today. The FDIC NPRM establishes US Treasury bills as the primary permitted reserve asset class for all PPSIs with strict maturity, liquidity, and custody documentation requirements. Simultaneously the DTCC DTC tokenization pilot launching H2 2026 — cleared by SEC no-action letter — will bring US Treasury securities including T-Bills onchain for 50+ institutional participants on pre-approved blockchains. Every MCI holding T-Bills as GENIUS Act reserve backing must document its T-Bills identity in a format satisfying OCC examination standards, FDIC BSA requirements, and BIS prudential standards simultaneously before July 18, 2026.
→ Source: FDIC GENIUS Act Proposed Rule — T-Bills Reserve Requirements, April 7, 2026mcitbills is the T-Bills identity built for the reserve asset standard that the GENIUS Act places at the foundation of every compliant stablecoin issuer. US Treasury bills — short-duration, highly liquid, credit-risk-free instruments — are the primary permitted reserve asset class under the GENIUS Act FDIC Proposed Rule, the OCC capital treatment guidance, and the BIS FSI Paper No. 27 prudential framework simultaneously.
Multifunction Cryptoasset Intermediaries that hold T-Bills as reserve backing face a precise institutional challenge: documenting that their T-Bills holdings meet the duration, liquidity, and custody standards that distinguish compliant MCI reserve management from the opaque earn-product structures that caused the Celsius and FTX collapses of 2022.
mcitbills.com & .eth is the Convergence Identity for this infrastructure layer — the institutional namespace that signals MCI-compliant T-Bills reserve management to the OCC, FDIC, and BIS simultaneously.

Why T-Bills Reserve Documentation Becomes a Binding GENIUS Act Requirement in 37 Days
The FDIC GENIUS Act Proposed Rule establishes US Treasury bills as the primary permitted reserve asset class for PPSIs — requiring 1:1 backing with instruments meeting strict maturity, liquidity, and credit quality standards. T-Bills issued by the US government with maturities of 90 days or less are the gold standard reserve asset under this framework.
The BIS FSI Occasional Paper No. 27 identified maturity mismatch between short-term customer liabilities and longer-term asset deployments as a core MCI vulnerability — T-Bills as reserve assets directly address this risk by matching the short-duration liability profile of stablecoin redemptions. The FRB, OCC, and FDIC Joint FAQ of March 5, 2026 confirmed that the capital rule is technology neutral — eligible tokenized T-Bills receive the same capital treatment as non-tokenized forms, creating immediate demand for MCI T-Bills infrastructure operating both on and off-chain. The permitted reserves standard governing T-Bills eligibility under the GENIUS Act is documented at permittedreserves.com & .eth.
The DTCC DTC tokenization pilot launching H2 2026 will bring US Treasury securities including T-Bills onchain for over 50 institutional participants — establishing the operational infrastructure within which MCI T-Bills reserve management will function. Every institution participating in the DTCC pilot and holding tokenized T-Bills as GENIUS Act reserve backing must establish a documented T-Bills identity before both the July 18, 2026 GENIUS Act deadline and the H2 2026 DTCC pilot launch converge. The clearing intent documentation standard for DTCC tokenized T-Bills transfers is documented at clearingintent.com & .eth.
How MCI T-Bills Reserve Documentation Distinguishes Compliance from Opacity
Every Multifunction Cryptoasset Intermediary managing T-Bills as reserve backing faces the same institutional challenge: how does it demonstrate to the OCC, FDIC, and BIS that its T-Bills holdings meet the duration, liquidity, and custody standards for MCI reserve compliance — and does it own that identity in both Web2 and Web3?
mcitbills.com is the institutional answer — the compliance portal, the T-Bills infrastructure brand, and the legal identity for any MCI that must document its short-duration Treasury reserve management under the GENIUS Act and BIS prudential standards. mcitbills.eth is the on-chain complement — an ENS-resolvable endpoint where T-Bills holdings attestations, maturity records, and reserve composition documentation can be stored as immutable distributed ledger entries.
The critical distinction between compliant MCI T-Bills management and the opaque structures that failed at Celsius and FTX is precisely this documentation layer — the ability to prove at any moment that T-Bills holdings are segregated, liquid, and match the duration profile of outstanding stablecoin liabilities. The PPSI settlement infrastructure executing T-Bills-backed redemptions is documented at ppsisettlement.com. The MCI ledger infrastructure recording T-Bills reserve attestations as immutable entries is documented at mciledger.com & .eth.
The MCI T-Bills Ecosystem — From Reserve Backing to Tokenized Treasury Settlement
mcitbills is the short-duration reserve core of the MCI namespace. It connects directly to mcitreasury.com & .eth as the broader Treasury identity encompassing all US government securities within the MCI reserve stack, and to mcisettle.com & .eth as the settlement layer executing T-Bills movements within the MCI infrastructure.
Beyond the MCI cluster, mcitbills integrates with permittedreserves.com & .eth as the OCC permitted reserve asset standard governing T-Bills eligibility, clearingintent.com & .eth as the clearing intent documentation standard for DTCC-tokenized T-Bills transfers, fhetbills.com & .eth as the FHE privacy-preserving layer for confidential T-Bills reserve management, and atomictbills.com & .eth as the atomic settlement standard for instantaneous T-Bills transfer and redemption.
An institution acquiring mcitbills.com & .eth secures the namespace for the most operationally critical MCI reserve asset category — the short-duration Treasury instrument that every GENIUS Act-compliant stablecoin issuer must hold as its primary reserve backing.
