Stablecoins and the Relationship with Dollar Hegemony: Digital Extension and the Possibility of Cracks

Key Summary

Stablecoins do not replace dollar hegemony; rather, at present they more often extend it digitally. The reason is simple: the vast majority of dollar-pegged stablecoins build their reserves with U.S. Treasuries, repo, and cash-equivalent assets, and fix the basic unit of payment, remittance, and transaction settlement to the dollar. On-chain dollars provide overseas users with cheaper and faster access to dollars than traditional banking networks, but that access operates largely through private issuers like USDC/USDT and the U.S. regulatory framework. In other words, infrastructure that appears decentralized is in fact re-tethered to the dollar, U.S. Treasury bonds, and regulatable issuers.

However, possibilities for cracks do exist. Non-dollar stablecoins, on-chain payments based on national currencies, decentralized settlement rails, regulatory fragmentation, issuer run risk, and liquidity problems in reserve assets could weaken dollar centrality. But the real-world data from 2024–2026 still points to the opposite. The United States has established a regulatory framework for payment stablecoins via the GENIUS Act, and the Treasury is pushing forward with implementation rules. The market has fragmented more deeply into USDT, USDC, PYUSD, and FDUSD, yet the global settlement unit remains the dollar.

1. Conclusion

  • Stablecoins tend to strengthen dollar hegemony rather than weaken it.
  • The core of this strengthening is: (a) expanded demand for U.S. Treasuries, (b) on-chain transplantation of dollar payment infrastructure, (c) low-cost proliferation of dollarization abroad, (d) expansion of sanctions and surveillance capacity, and (e) the re-absorption of informal finance into dollar-centered private infrastructure.
  • Paths toward weakening exist but remain limited. The share of non-dollar stablecoins is small, and most major market participants and exchanges use dollar-pegged assets as the standard.

2. Mechanisms by Which Stablecoins Strengthen Dollar Hegemony

2.1 They Directly Create Demand for U.S. Treasuries

Dollar-pegged stablecoins place a significant portion of their reserves in U.S. Treasuries, repo, and cash-equivalent assets. This is essentially a structure in which the reserves of privately issued digital dollars are converted into demand for U.S. government short-term debt.

  • USDC is known—through public reports and market coverage—for a reserve structure centered on U.S. Treasuries and repo.
  • Tether’s 2025 attestation reportedly mentioned approximately $135.2 billion in U.S. Treasury exposure.
  • Market coverage repeatedly analyzes that stablecoin growth alone could generate massive future demand for U.S. Treasuries.

From a political economy perspective, the more the private sector wants dollar liquidity, the more the short-term borrowing capacity of the U.S. fiscal state is strengthened behind that liquidity. This thickens the financial foundation of dollar hegemony.

2.2 They Extend Payment Infrastructure on-Chain

Stablecoins provide a simpler payment layer than bank accounts. They are particularly strong in cross-border payments.

  • 24/7 settlement
  • No need for counterparty bank networks
  • Improved settlement speed compared to card networks and SWIFT
  • Programmable payments

This structure does not merely digitalize the dollar; it transplants dollar payment infrastructure onto the blockchain. As long as the settlement unit is the dollar, improvements in user experience expand the domain of dollar usage.

2.3 They Expand Dollarization Abroad

In Asia, Latin America, Africa, and elsewhere, stablecoins function as a form of legal/quasi-legal internet dollar.

  • Savings vehicle in inflationary countries
  • Payment for imports
  • Remittances for freelancers/remote workers
  • Base currency on exchanges

This is the on-chain version of the traditional Eurodollar market. When dollar demand arises outside a country, that demand—whether more informal or more formal—ultimately gets absorbed into dollar assets.

2.4 They Strengthen Sanctions and Surveillance Capacity

On-chain dollars are often advertised as “censorship-resistant,” but in practice major stablecoin issuers can perform freezes, blocks, and blacklisting.

  • Issuers can block addresses
  • Exchanges/on-ramps can apply KYC/AML
  • Traceability by analytics firms and investigative agencies is high

In other words, even if informal workarounds increase, the large channels become re-centralized. This paradox is important: the more decentralized infrastructure is used, the more actual funds come under centralized control.

2.5 Workarounds Actually Produce Re-Centralization

Users turn to stablecoins to bypass banks, but large-scale transactions again require:

  • Major issuers
  • Major exchanges
  • Payment service providers
  • Regulatory licenses in the U.S., Singapore, Hong Kong, etc.

Thus it is not “disintermediation” but relocation of intermediaries. Dollar hegemony does not disappear; only the owners of financial infrastructure change. Politically and economically, this amounts to a re-expansion of the U.S.-centered private monetary sphere.

3. Paths That Could Weaken Dollar Hegemony

3.1 Non-Dollar Stablecoins

Euro, Singapore dollar, Hong Kong dollar, and yuan-based stablecoins could create cracks in dollar monopoly. According to Forbes reporting, the total size of non-dollar stablecoins as of March 2026 was mentioned at approximately $1.2 billion. Still small.

The problem is twofold:

  • Liquidity is shallow
  • The standard for exchanges and payment networks remains the dollar

Thus non-dollar stablecoins have symbolic significance but their systemic substitutive power is still weak.

3.2 Decentralized Settlement

Some protocols try to reduce dependence on centralized issuers. But full decentralization is difficult.

  • Collateral asset problems
  • Oracle problems
  • Clearing/settlement rail problems
  • User on-ramp/off-ramp problems

The larger the real usage, the more it converges toward centralized gateways. So in the current market, decentralized settlement does not dismantle dollar hegemony; it largely supplements on-chain dollar-based settlement.

3.3 Regulatory Risk

If the U.S. fully co-opts stablecoins, dollar hegemony is strengthened, but excessive regulation could fragment the market simultaneously.

  • Enhanced KYC/AML
  • Prohibition of interest payments
  • Issuer licensing
  • Reserve and disclosure requirements

Such regulation can increase market trust, but may also slow the pace of innovation. However, so far regulation moves toward co-optation rather than closure.

3.4 Reserve Asset Dependency and Run Risk

Stablecoins are inherently parasitic banking: they perform maturity and liquidity transformation.

  • Promise of instant redemption
  • Holding long/short-term assets
  • Concentrated redemptions during panic

If reserve assets are insufficiently safe or market confidence shakes, large-scale redemptions can occur. In that case, the result would be not strengthened dollar hegemony but collapse of trust in private digital dollars.

4. Case Comparisons

4.1 USDC

  • Issued by Circle
  • Reserves centered on U.S. Treasuries, repo, cash-equivalent assets
  • Regulation-friendly
  • Representative on-chain dollar for payments, remittances, institutional use

Assessment: The clearest case of dollar hegemony strengthening effect. Rapid integration into the institutional framework.

4.2 USDT

  • Issued by Tether
  • Market dominance remains overwhelming
  • Reported at approximately $186 billion at end of 2025
  • 2025 Q3 attestation mentioned U.S. Treasury exposure of about $135.2 billion

Assessment: Institutionally more of a gray area, but in practice it supplies dollar liquidity most broadly worldwide. Core of informal dollarization.

4.3 PYUSD

  • Issued by PayPal
  • On 2026-03-17, PayPal announced expansion of access to 70 markets
  • Direct integration with consumer payment networks

Assessment: A case of a large payment platform internalizing dollar stablecoins. Consumer-level expansion of dollar hegemony.

4.4 FDUSD

  • Heavily utilized within the Binance ecosystem
  • Strong character as a liquidity asset for trading
  • Closer to a dollar token for trading infrastructure than a “dollar replacement”

Assessment: An auxiliary asset maintaining dollar-centered trading liquidity.

4.5 Non-Dollar Stablecoins

  • Total volume still small
  • Experiments with national currency units in some countries/regions are meaningful, but weak as a global reserve replacement

Assessment: A crack factor in dollar hegemony, but currently at the level of peripheral experiments.

5. 2024–2026 Regulatory and Policy Trends

United States

  • GENIUS Act: Establishes a regulatory framework for payment stablecoins.
  • Reportedly enacted in July 2025.
  • On 2026-04-01, the Treasury began public comment on implementation rules.
  • Congress is concurrently discussing market structure bills such as STABLE Act, CLARITY Act.
  • Common direction is not “prohibition” but management of licensed private dollars.

Global

  • EU MiCA works favorably for compliant assets like USDC.
  • Singapore and Hong Kong are moving to broaden the allowable scope for dollar-based/multi-currency stablecoins.
  • As a result, global regulation is not eliminating stablecoins but relocating them as institutional settlement assets.

6. Political Economy Interpretation: Digital Extension of Dollar Hegemony

From a Marxist-Leninist/political economy perspective, stablecoins are not merely a payment innovation. They represent the process by which the dollar, as the dominant money form, combines with digital platform capital to reconstruct itself as a global capture apparatus.

The core is threefold.

  1. Digitalization of the value-form
  • The dollar is no longer confined to bank accounts.
  • It gains global circulation in token form.
  1. Imperialization of private intermediaries
  • The state does not build all payment networks directly.
  • Private actors such as Circle, Tether, PayPal, and Coinbase effectively take charge of quasi-public infrastructure.
  1. Making hegemony invisible
  • To users, it appears “decentralized.”
  • In reality, it is backed by U.S. regulation, U.S. Treasuries, and dollar clearing networks.

Therefore, stablecoins are not an anti-dollar technology; at the present juncture, it is more accurate to see them as a platformized extension of dollar hegemony.

7. Final Assessment

  • Strengthening factors dominate: Treasury demand, payment expansion, dollarization abroad, sanctions/surveillance, re-centralization of private infrastructure.
  • Weakening factors exist: Non-dollar assets, decentralized settlement, regulatory fragmentation, run risk.
  • But as of 2026, the market center remains dollar stablecoins.
  • Hence, current stablecoins are not a technology that undermines dollar hegemony but a technology that globalizes dollar hegemony more cheaply, faster, and more deeply.

9. One-Line Conclusion

Stablecoins are not the end of dollar hegemony; they are that hegemony repackaged on the blockchain.
