# 1.1 穩定幣的演進

* 穩定幣已從最初服務於區塊鏈交易的「價值錨定工具」，演進為全球金融體系的核心基礎設施之一。其功能不再局限於作為交易媒介，更擴展至跨境支付、價值儲存以及支援人工智能與機器經濟的新一代數碼貨幣體系。

#### 全球市場動態

* 截至2025年中，全球穩定幣總市值達2,460億美元
* 美元穩定幣（如USDT、USDC）佔據全球超過九成交易份額
* 穩定幣已逐漸成為自主AI系統與機器對機器（M2M）交易的基礎貨幣

#### 監管架構演變

* **美國：**&#x53C3;議院通過《穩定幣法案》，確立穩定幣與傳統金融融合的監管框架，預計將吸引大規模機構資金進場，並重塑DeFi流動性格局
* 新加坡：根據《支付服務法》監管穩定幣轉帳，XSGD等項目體現政府對「受控創新」的政策導向
* **歐盟：**&#x5BE6;施《加密資產市場規例》（MiCA），依資產類型分類管理穩定幣，並強制全額儲備及透明化，構建統一的數碼資產監管體系
* **離岸人民幣：**&#x65BC;東南亞與非洲貿易結算中的滲透速度加快，特別是在推動RWA場景與跨境B2B物流領域成效顯著
