You might think that a stablecoin issuer spreading reserves across multiple banks would definitely have stronger redemption capability — if one bank fails, others can still cover.
But the reality is: what truly determines single-day redemption capability is not the number of banks, but regulatory rules and the liquidity of underlying assets. According to the OCC's proposed rules implementing the GENIUS Act, when single-day redemptions exceed 10% of circulating supply, issuers are allowed to extend the redemption period to 7 days. Bank diversification does not change this limit, but it does affect how closely an issuer can approach that limit.
First, Look at the Rules: The Legal Ceiling for Single-Day Redemption
The OCC's proposed rules set the following redemption timelines:
Under normal conditions: Redemption requests are completed within 2 business days.
Triggering the extension mechanism: If single-day redemption requests exceed 10% of total circulating supply, the redemption period automatically extends from 2 business days to 7 calendar days.
No early redemption: During the extension period, redemptions cannot be processed early unless specifically approved by the OCC.
The original intent of this mechanism is to give issuers time to sell assets in extreme situations. But American Banker's analysis pointed out a side effect: once market participants know this threshold, they may rush to redeem before it is triggered, actually accelerating a bank run.
Bank Diversification Solves a Different Type of Risk
Spreading reserves across multiple banks mainly addresses single-bank failure risk — in 2023, USDC depegged to $0.87 precisely because Circle had $3.3 billion in reserves held at Silicon Valley Bank, and the bank's collapse froze those funds.
If reserves are spread across multiple banks, the impact of a single bank failure on redemption capability would be smaller. But this does not change the 10% redemption threshold rule.
What Truly Determines Single-Day Redemption Capability Is the "Speed of Reserve Liquidation"
To verify single-day redemption capability, focus on two questions:
Question One: How much of the reserves can be "moved instantly"
Cash and bank demand deposits: Can be redeemed immediately and are not subject to the 7-day window.
Short-term U.S. Treasury bills: Liquid market, but may face discounts during large-scale sell-offs. BIS research shows that selling $30 billion in Treasury bonds at low prices can move yields by 6.4 basis points.
Overnight repurchase agreements: Can also be liquidated quickly.
Circle's reserves are primarily held through the Circle Reserve Fund managed by BlackRock, which currently has no liquidity fees or redemption gates (though the board can modify policies with advance notice). The cash portion is spread across multiple regulated banks, such as BNY Mellon.
Differences Between Issuers
| Issuer | Reserve Structure | Single-Day Redemption Capability |
|---|---|---|
| USDC | Cash + short-term U.S. Treasuries, managed by BlackRock, with monthly attestation reports from Deloitte | Normal redemptions within 2 business days; reserves spread across multiple banks, lower single-bank risk |
| USDT | Approximately 77% cash equivalents, remainder in gold and Bitcoin, total over-collateralized by 3% | Historical records show full redemption during 20-25% redemption waves, but reserves include volatile assets such as gold and Bitcoin |

How Should You Evaluate This?
[What to do]: Verify the single-day redemption capability of the stablecoin you hold, rather than just looking at "how many banks."
[How to do it]:
Check the reserve composition report: Download the latest reserve report from the issuer's official transparency page. Focus on two numbers: the proportion of cash and overnight assets (this portion can be redeemed directly), and the maturity distribution of short-term Treasury bills (the shorter, the better).
Confirm bank concentration: If reserves are concentrated in a few banks, single-bank failure risk is higher. USDC reserves are spread across multiple U.S. banks — the 2023 depeg was precisely due to SVB concentration risk being exposed.
Understand historical redemption performance: Tether fully redeemed during a 20-25% redemption wave, which is a record of actual stress testing.
[Completion standard]: You can clearly explain how much of your held stablecoin's reserves are "immediately accessible" assets, and what proportion would require 7 days to liquidate in a worst-case scenario.
