From Dollar Hegemony to On-Chain Dollars: How Stablecoins Are Reshaping Global Capital Flows

·

May 21, 2025 marked a watershed moment as Hong Kong’s Legislative Council unanimously passed the Stablecoin Ordinance, establishing the world’s first comprehensive regulatory framework for fiat-backed stablecoins. While superficially reinforcing the dollar’s dominance—pegged to USD and backed by U.S. Treasuries—stablecoins fundamentally unshackle the dollar from traditional banking systems, enabling cross-border flows that bypass SWIFT and regulatory layers via blockchain networks.

This is not a challenge to the dollar’s credibility but a revolution in how it circulates globally. Below, we dissect the institutional logic of stablecoins, their impact on U.S. debt dynamics, and the emerging investment opportunities.


Stablecoins: The Interface for "On-Chain Dollars"

Stablecoins extend existing monetary systems into the digital realm by pegging real-world assets to blockchain-based tokens. They bridge traditional finance and crypto ecosystems, enhancing transactional stability and cross-border efficiency. Three primary types exist:

  1. Fiat-Collateralized Stablecoins (e.g., USDT, USDC):

    • Backed 1:1 by fiat reserves (typically USD/short-term Treasuries).
    • Reliant on issuer transparency (e.g., Circle’s audited reserves for USDC).
  2. Crypto-Collateralized Stablecoins (e.g., DAI):

    • Overcollateralized with volatile assets (e.g., 150% ETH抵押).
    • Decentralized but prone to liquidation risks during market turbulence.
  3. Algorithmic Stablecoins (e.g., defunct UST):

    • Peg maintained via supply mechanics (e.g., dual-token models).
    • High susceptibility to death spirals during confidence crises.

The Dollar’s "Rentier" Mechanism: Three Layers of Control

  1. Debt-Driven Monetary Supply:

    • U.S. deficits are globalized via Treasury purchases by central banks/institutions.
  2. Dollar Pricing Power:

    • Commodities (oil, gold) and financial assets (stocks, bonds) are USD-denominated.
  3. SWIFT Monopoly:

    • Controls 90%+ of cross-border payments, enabling U.S. sanctions (e.g., Iran, Russia).

Stablecoins disrupt Layer 3 by enabling peer-to-peer flows outside SWIFT, shifting control from governments to private issuers and smart contracts.
