The US government is making a strategic push to proliferate US Treasury-backed stablecoins, aiming to reinforce the US dollar’s global dominance in the digital era. The idea is to enable more people around the world to transfer and use stablecoins seamlessly via smartphone apps—a move that could redefine global finance.
To achieve this, the US needs scalable, efficient, and widely accessible digital infrastructure. This raises key questions:
- Which blockchains (if any) will the US rely on?
- Will decentralized networks like Solana play a role, or will Big Tech platforms control the stablecoin ecosystem?
- Could the US create its own Ethereum Layer 2 solution?
- How does this all fit into the larger geopolitical battle for financial dominance?
This deep dive explores the technological, economic, and geopolitical angles of the US stablecoin strategy.
Why the US Wants Treasury-Backed Stablecoins
Stablecoins backed by US Treasuries or US dollars offer the US government several key advantages:
1. Maintain Global Dollar Hegemony
- The US dollar currently dominates global trade, but alternative payment systems are emerging (e.g., China’s digital yuan, BRICS’ de-dollarization efforts).
- A digital, blockchain-based dollar ensures the world continues using USD in the digital financial era.
2. Compete with China’s Digital Yuan
- China has been aggressively pushing its Central Bank Digital Currency (CBDC), the e-CNY, especially for cross-border transactions and trade settlements.
- If the digital yuan gains too much traction, the US could lose its ability to sanction nations and control global financial flows.
- A fast, global, and easily accessible US stablecoin system counters this threat.
3. Increase Financial Surveillance & Control
- Unlike cash, stablecoins are traceable, making them a powerful tool for sanctions enforcement, anti-money laundering (AML), and counter-terrorism financing (CTF).
- The US can monitor financial flows in real-time while still allowing “decentralized” usage to attract global adoption.
4. Modernize the US Financial System
- The current US banking system relies on outdated settlement networks like SWIFT and ACH, which are slow and costly.
- Stablecoins settle instantly, 24/7, with lower fees, making them a better alternative for global transactions.
Which Blockchains Could Power Treasury-Backed Stablecoins?
To achieve mass adoption, stablecoins must operate on fast, low-cost, scalable, and secure infrastructure. The Ethereum mainnet is too slow and expensive, making it unsuitable. Instead, viable options include:
| Blockchain | Speed | Cost Per Transaction | Current Stablecoin Usage | Potential for US Adoption |
|---|---|---|---|---|
| Solana | Fast (400ms blocks) | <$0.01 | Strong (USDC, USDT widely used) | High |
| Sui & Aptos | Fast | Low | Small adoption | Moderate |
| Ethereum Layer 2s (Base, Optimism, Arbitrum, etc.) | Fast (via rollups) | Low | Growing | High |
| A Government-Backed Blockchain | Customizable | TBD | Would need adoption push | High |
Solana: The Most Likely Candidate
- Extremely fast & cheap: Handles 65,000 transactions per second with almost zero fees.
- Already used for stablecoins: USDC and USDT on Solana are among the most transferred stablecoins.
- A growing DeFi ecosystem: Many payment services and businesses are already building on Solana.
Could the US Use an Ethereum Layer 2 for Stablecoins?
Ethereum’s Layer 1 is too slow and expensive, but Layer 2 solutions (L2s) offer high-speed, low-cost transactions while benefiting from Ethereum’s security.
How an Ethereum Layer 2 Could Be Used
- The US could launch its own government-backed L2 (e.g., a “FedNet” on Ethereum).
- Banks could launch a regulated L2 (e.g., JPMorgan or Citi-backed layer 2 networks).
- Big Tech could run its own L2 (e.g., Coinbase’s Base becoming the dominant L2 for stablecoins).
Why Ethereum Layer 2s Are an Attractive Option
- Security: L2s inherit Ethereum’s decentralization and security.
- Regulatory Control: The US could enforce compliance at the L2 level.
- Institutional Adoption: Banks and fintech companies already use Ethereum and L2s.
What’s the Most Likely Outcome?
- Stablecoins on Public Blockchains (Solana, Ethereum L2s, etc.)
- Big Tech Payment Integrations (Apple Pay, Meta, PayPal, Google Pay)
- A US-Friendly Financial Infrastructure
- Selective Censorship & Regulatory Control
Final Thoughts
- US Treasury-backed stablecoins will reshape global finance.
- Solana, Ethereum L2s, and Big Tech platforms will likely play a major role.
- The US must balance regulation with decentralization to ensure adoption.
- Geopolitical battles over financial control will intensify.
In short, stablecoins are the next front in the digital financial war—and the US is moving fast to ensure it stays on top.
