How Do Stablecoin Issuers Hold Their Reserves?
They back each token fully with safe, liquid assets like short-term Treasury bills and hold capital against operational and credit risks.

Stablecoin issuers must hold reserves fully backing each token in short-term, high-quality liquid assets like Treasury bills, and under Fed proposals would also face capital and risk-management requirements.
What are stablecoin reserves?
Reserves are the assets behind every token
Under the GENIUS Act, stablecoin reserves are the assets an issuer holds to back each token in circulation. Reserve Standards vs. Issuer Restrictions: The GENIUS Act's ... Under the GENIUS Act, these assets ensure that anyone who holds a token can redeem it for face value at any time. Reserve Standards vs. Issuer Restrictions: The GENIUS Act's ... Without full backing, a stablecoin would not be stable because its value could fall below the reference currency. The idea is similar to a prepaid gift card, where the card company keeps the money you loaded in a safe bank account.
Full backing means equal value coverage
Under the GENIUS Act, full backing means the issuer holds assets equal in value to the total number of tokens outstanding. Reserve Standards vs. Issuer Restrictions: The GENIUS Act's ... This equal value coverage protects holders because the issuer can sell the assets to honor redemptions. If reserves were partial, a wave of redemptions could force the issuer to sell assets at a loss or delay payouts. The prepaid gift card analogy works because the card company does not spend the money you loaded; it keeps it ready for when you use the card.
Why reserves matter for trust
Stablecoins are meant to hold a steady value, so holders need confidence that they can get their money back. Reserves are the concrete promise behind that confidence. Under the Federal Reserve's proposed GENIUS Act rules, if the reserve assets are safe and liquid, the stablecoin can withstand market stress and large redemption requests.

What assets can issuers hold in reserves?
Short-term government debt is the core
Under the Federal Reserve's proposed GENIUS Act rules, short-term U.S. Treasury bills are considered high-quality and liquid because they can be easily sold for cash. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The Federal Reserve's proposed GENIUS Act rules require holding reserves in such high-quality, liquid assets, which helps ensure the issuer can meet redemptions even in a stressed market. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The idea is to mimic the safety of a prepaid gift card, where the money is kept in a safe bank account rather than risky investments.
Other high-quality liquid assets may be allowed
Under the Federal Reserve's proposed GENIUS Act rules, in addition to short-term U.S. Treasury bills, issuers may hold other high-quality, liquid assets. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers These could include central bank reserves or highly rated short-term securities. The Federal Reserve's proposed GENIUS Act rules require full backing with assets that are both safe and easily convertible to cash. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The goal is to avoid the kind of asset mismatch that could cause a stablecoin to break away from its pegged value.
Full backing is non-negotiable
Under the Federal Reserve's proposed GENIUS Act rules, issuers cannot back tokens with anything less than the full value of circulating tokens. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers Under the GENIUS Act, the reserve portfolio must always be at least equal to the number of tokens multiplied by their face value. Reserve Standards vs. Issuer Restrictions: The GENIUS Act's ... The Federal Reserve's proposed GENIUS Act rules would prevent fractional reserve practices because full backing means holding assets against tokens issued rather than relying on a smaller pool. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The prepaid gift card analogy applies because the card company must keep all loaded funds available, not invest them in illiquid assets.

How does the Fed's proposal make reserves safer?
Capital buffers for credit and operational risk
The Federal Reserve's reserve proposal would require stablecoin issuers to hold capital against potential losses from credit risk and operational failures. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The Federal Reserve's reserve proposal covers credit risk, the chance that a reserve asset loses value, and operational risk, technology or process breakdowns. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The Federal Reserve's reserve proposal would set capital requirements that act like a cushion beyond reserves, absorbing losses before they hit token holders. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers This is like a gift card company keeping extra cash aside to cover fraud or system outages in addition to the loaded funds.
Risk-management standards for issuers
The Federal Reserve's reserve proposal would require issuers to adopt strong risk-management practices for their reserve portfolios. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The Federal Reserve's reserve proposal risk-management standards would require regularly monitoring quality, liquidity, and market risk of reserve assets. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers They would also need plans for how to handle large redemption requests or sudden market moves. The Federal Reserve's reserve proposal risk-management standards make reserves safer because they force issuers to think through worst-case scenarios.

Safekeeping rules for backing assets
The Federal Reserve's reserve proposal would also set rules for firms that safeguard reserve assets on behalf of issuers. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers These custodians would face requirements to keep the assets segregated and protected. If a custodian failed, the stablecoin reserves would still be identifiable and accessible to the issuer. This adds another layer of safety, similar to how a bank keeps gift card funds separate from its own operating money.

How do banks get approval to issue stablecoins with reserves?
A tailored application for banks
Under the Federal Reserve's second proposal, an insured state member bank would need to apply for approval before issuing stablecoins through a subsidiary. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The Federal Reserve's second proposal would require a business plan describing how the stablecoin would operate and how reserves would be managed. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers Under the Federal Reserve's second proposal, financial information and projections would also be required to show the bank can support the new activity safely. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers This tailored process is designed to fit the specific risks of stablecoin issuance rather than using a uniform bank application.
Review focuses on safety and soundness
Under the Federal Reserve's second proposal, the central bank would review the application to ensure the bank has the risk-management capacity and capital to back its stablecoin. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The review would look at the quality of the reserve assets and the bank's plans for liquidity under stress. Approval would come only if the central bank is confident the stablecoin would not threaten the bank's overall safety. This is like a gift card company needing a license to hold customers' funds in a separate account.
Timelines for decisions
Under the GENIUS Act, the central bank has 120 days to decide a complete application, setting clear timelines. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers The GENIUS Act gives the Fed 120 days to decide a complete application, so the bank would submit its complete application and the regulator would have a defined period to approve or deny it. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers Extensions would be possible only if more information is needed or if the applicant agrees. The GENIUS Act's 120-day deadline gives banks certainty about how long the approval process will take. Fed proposes GENIUS Act rules for stablecoin reserves and bank issuers

Why do stablecoin reserves matter for the banking system?
Reserves can draw funds away from bank deposits
If stablecoins become widely used, some money that would otherwise sit in bank deposits may move into stablecoin reserves. Those reserves are often held in government securities, not in bank deposits, so banks lose a source of low-cost funding. This displacement can change how banks fund their lending and other activities. The prepaid gift card analogy shows that money loaded onto a card is no longer in your checking account.
Banks face new liquidity and funding risks
When stablecoin reserves grow quickly, banks may need to replace lost deposits with other, possibly more expensive or less stable funding. That could increase liquidity risk because the new funding may flee in a crisis. Central bank research has highlighted that this shift could change the overall stability of bank funding. A stablecoin issuer holding reserves in government debt does not lend that money back to the economy the way a bank deposit might.
Credit provision could be affected
Bank deposits are a key source of funds for loans to businesses and households. If stablecoin reserves reduce those deposits, banks might have less capacity to extend credit. That could tighten credit conditions or raise borrowing costs for the broader economy. Regulations on stablecoin reserves therefore matter not just for token holders but for the health of the banking system as a whole.
Key Takeaway: Full backing with safe assets
Stablecoin issuers are moving toward holding high-quality liquid reserves such as short-term Treasury bills and bank deposits to fully back tokens. Reserve composition varies widely by issuer, and new Fed rules under the GENIUS Act set full-backing and capital requirements.
