Key takeaways
-
Tether runs a cash and repos rich balance sheet, holding $181.2 billion in reserves against $174.5 billion in liabilities, leaving $6.8 billion in surplus.
-
High interest rates have turned these reserves into profits, generating over $10 billion in interest income so far in 2025, which is rare for a typical crypto issuer.
-
It exercises political leverage by freezing sanctioned wallets, moving supported blockchains, and allocating up to 15% of profits to Bitcoin.
-
Comparing central banks has limits. Tether has no public mandate or safety net, relies on attestations rather than comprehensive audits, and relies on private counterparties.
Tether no longer looks like just a stablecoin company. Its balance sheet is filled with short-term US Treasuries, reverse repos, gold and even Bitcoin (BTC). It mints and redeems dollars on a large scale and can freeze addresses at the request of law enforcement.
Its latest attestation shows $181.2 billion in reserves against $174.5 billion in liabilities, leaving $6.8 billion in surplus and more than $174 billion in USDt (USDT) in circulation. With high interest rates, this treasure-rich wallet has generated over $10 billion in profits so far in 2025, a figure more typical of a financial institution than a crypto startup.
This is why critics and supporters argue that Tether behaves like a private, dollar-linked central bank for parts of the crypto economy, but without a sovereign mandate or safety net.
Acting like a central bank: what does that mean?
In practice, Tether does four things that resemble the behavior of a central bank.
First, it issues and redeems money on demand. Verified customers create new USDT by wiring them to fiat and exchange them by sending USDT back to dollars. This primary market expands or reduces supply, while secondary market trading takes place on exchanges. The actual balance sheet changes take place within this money and redemption pipeline.
Second, it manages the reserves like a fixed-income desk, placing most assets in short-duration U.S. Treasuries and repos, with some gold and Bitcoin. A Treasury-heavy portfolio preserves liquidity and adds steady demand for Treasuries, which bond offices now actively track when identifying major buyers of U.S. debt.
Third, it generates what looks like seigniorage in a high-rate environment. Users hold a non-interest-bearing token, while Tether collects interest on treasuries, which generated over $10 billion in profits and $6.8 billion in excess reserves in the third quarter of 2025. This revenue stream is why the “private central bank” comparison resonates.
Finally, it uses policy-like tools such as contract functions that can freeze addresses at the request of law enforcement or sanctions authorities. It also has the ability to add or remove blockchains, for example terminating Omni, BCH-SLP, Kusama, EOS and Algorand, to manage operational risk.
Although this is not sovereign monetary policy, it nevertheless represents active intervention in a dollar asset used by hundreds of millions of people.
Did you know? Tether was initially launched as Realcoin in July 2014 and renamed Tether in November of the same year. It remains one of the oldest stablecoins still in active use today.
Develop policy levers that resemble central bank tools
Tether now intervenes in its own dollar system in a way that resembles political tools.
On the compliance side, it can freeze addresses linked to sanctions or repressive actions. It first introduced a proactive wallet freezing policy in December 2023 and has since used it in specific cases, such as wallets linked to the sanctioned Russian exchange Garantex. These are issuer-level interventions that immediately affect who can move dollar liquidity on-chain.
On the market operations side, Tether’s reserves are managed as a short-term fixed income portfolio, heavily weighted in US Treasuries and reverse repos. This structure allows minting and redemption activities to align with highly liquid assets that earn interest while maintaining flexibility.
According to Tether’s latest affidavit, this combination has helped generate billions of dollars in profits and a large buffer of excess reserves. These mechanisms are similar to open market type management, even if Tether remains a private issuer rather than a central bank.
Tether also defines its own operational scope. It has added and removed blockchains to focus activities where usage and infrastructure are strongest, ceasing minting and later supporting existing networks such as Omni, BCH-SLP, Kusama, EOS and Algorand, while continuing buyouts during a transition period.
Additionally, it diversifies reserves by allocating up to 15% of earned operating profits to Bitcoin, a policy introduced in 2023 that represents another issuer-level decision with system-wide effects.
From stablecoin issuer to infrastructure player
Over the past 18 months, Tether has grown from a single token company to a broader financial infrastructure group.
In April 2024, it reorganized into four operating divisions: Tether Finance, Tether Data, Tether Power and Tether Edu. These divisions manage Tether’s digital asset services, data and AI projects (such as Holepunch and Northern Data), energy initiatives and educational programs. The restructuring formalized a strategy that goes well beyond the issuance of USDT.
On the energy side, Tether has committed capital and expertise to El Salvador’s Volcano Energy, a 241-megawatt wind and solar farm designed to power one of the world’s largest Bitcoin mining operations. The project directly supports the availability of payments and settlements. The company also ended support for several existing blockchains in order to concentrate liquidity where tools and demand are strongest, a network operating decision with ecosystem-wide effects.
To directly address the US market, Tether announced USAT (USAT), a US-regulated dollar token that will be issued by Anchorage Digital Bank under domestic rules, alongside its existing offshore USDT. If launched as described, USAT would provide Tether with a compliant onshore platform, while USDT would continue to serve global markets.
Why the analogy is broken
It is important to note that Tether is not a sovereign monetary authority.
It does not set interest rates, act as a lender of last resort, or operate under a public mandate. Its transparency still relies on quarterly certifications rather than a full financial audit, although the company says it has been in discussions with one of the big four firms about auditing its reserves.
This gap between attestation and audit is one reason critics reject the “central bank” label.
There are also balance sheet issues. Tether has at times maintained a portfolio of collateralized loans after previously saying it would reduce that exposure. This asset category attracts attention because the conditions and rewards are important. More broadly, the company relies on private banking, custody and pension counterparties rather than a sovereign safety net, meaning that market trust and infrastructure remains outside its direct control.
Finally, some of Tether’s most political actions are primarily compliance measures, such as proactively freezing addresses listed by sanctions authorities.
Did you know? In December 2023, Tether said it had assisted more than 140 law enforcement agencies in 45 jurisdictions to freeze $835 million linked to scams and illicit activities.
Tether’s place overall
Ultimately, Tether looks less like a typical stablecoin issuer and more like a dollar-denominated private central bank for crypto. It expands and shrinks supply through large-scale minting and redemptions, holds short-term Treasuries and repos, generates billions of dollars in interest income, and can intervene in compliance actions as necessary.
However, the analogy only goes so far. There is no public mandate or safety net, transparency still depends on certifications, and its policy actions are largely focused on compliance rather than macro management.
Keep an eye on reserve composition, earnings, buybacks, audit progress and, in the US, how the USAT plan with Anchorage is playing out, because that’s where the story will continue to look central bank-like or start to diverge.
