$USDC Tech giants (such as Meta and Amazon) issuing stablecoins will have a profound impact on the entire economic sphere:

1. **Reshaping Payment and Clearing Systems:** Giant stablecoins may challenge traditional banking payment and cross-border clearing systems (like SWIFT) due to their network effects and efficiency, significantly reducing transaction costs and time.

2. **Impact on Monetary Policy and Financial Stability:** Large-scale private currencies may weaken central banks' control over money supply and interest rates, with their potential run risks or technical failures possibly triggering systemic financial risks.

3. **Promoting Financial Inclusion and Efficiency:** Providing low-cost financial services to the global unbanked population and improving the cash flow efficiency of economic activities such as supply chains and cross-border trade.

4. **Exacerbating Data Monopoly and Privacy Concerns:** Combining the vast ecosystems of tech giants may result in a more comprehensive grasp of user payment and financial data, leading to stronger data monopolies and privacy protection issues.

5. **Accelerating the Construction of Global Regulatory Frameworks:** Forcing central banks and regulatory agencies (like the Federal Reserve and ECB) to accelerate the R&D of central bank digital currencies (CBDCs) and formulate strict regulatory rules for global stablecoins (covering reserve audits, anti-money laundering, etc.).

**Summary:** This is a "double-edged sword" that may enhance economic efficiency and inclusivity, but also threaten financial sovereignty and stability, while exacerbating the market dominance of tech giants and pushing for a faster transformation of the global financial regulatory system.
