The Bank for International Settlements (BIS) has declared that stablecoins, despite their technical advantages, have failed to meet the essential criteria of unity, elasticity, and integrity necessary for forming the core of a future monetary system. In its latest annual report, the BIS highlighted that stablecoins' issuance structures limit their scalability and lack unified settlement standards across different issuers. Additionally, discrepancies in anti-money laundering and compliance measures pose risks to national monetary sovereignty and financial system stability.
