#科技巨头入场稳定币 Tech giants (such as Meta and Amazon) issuing stablecoins will have a profound impact on the entire economic sphere:

1. **Reshaping the payment and settlement system:** Giant stablecoins may challenge traditional bank payment and cross-border settlement systems (such as SWIFT) due to their network effects and efficiency, significantly reducing transaction costs and time.

2. **Impacting monetary policy and financial stability:** Large-scale private currencies may weaken central banks' control over money supply and interest rates, with potential risks of runs or technical failures that could trigger systemic financial risks.

3. **Promoting financial inclusion and efficiency:** Providing low-cost financial services to the global unbanked population and enhancing the efficiency of capital flows in economic activities like supply chains and cross-border trade.

4. **Exacerbating data monopolies and privacy concerns:** Coupled with the giants' vast ecosystems, they may possess more comprehensive 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 bodies (such as the Federal Reserve and ECB) to expedite the development of central bank digital currencies (CBDCs) and establish strict regulatory rules for global stablecoins (covering reserve audits, anti-money laundering, etc.).

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