PMR-2026-0603-GLBL-001 · Blockchain & Digital Asset Markets
USD stablecoin issuers now constitute a non-bank, under-supervised demand block at the structural scale of mid-sized foreign sovereign holders of US Treasury bills. Tether alone reports direct and indirect T-bill exposure in the rank-band of named G20 holders. The binding stress vector for a treasurer or supervisor is not the Treasury auction; it is the deposit-bank custodian, and the March 2023 USDC episode at SVB is the empirical proof.

Key Judgments
Seven judgments anchor this assessment. Each is tied to cited evidence in the body of the brief and carries an explicit confidence level. The four below are the load-bearing four.
- High confidence. The aggregate stablecoin sector functions as a non-bank holder block of US Treasury bills at the rank-order scale of a mid-sized foreign sovereign. Tether alone sits at the rank-band of named G20 holders on the most recent TIC release.
- High confidence. The binding transmission channel is the cash-deposit side, not the asset side. A stress event is more likely to start with a deposit-bank failure or sanctions disruption at a custodian than with a Treasury auction price move.
- High confidence. Circle and Tether sit in two materially different evidentiary tiers. Any supervisor or allocator treating them interchangeably is mispricing the disclosure gap.
- Moderate confidence. The GENIUS Act (signed 2025-07-18) and the OCC NPR architecture together create a federal qualified issuer designation that materially raises the cost of operating outside the regime, but does not by itself force convergence inside one budget cycle.
