Core Insights - Stablecoins have evolved from a conceptual tool in the cryptocurrency ecosystem to a crucial infrastructure for real-world payments, trading, and asset allocation [1] - The appeal of stablecoins lies in their operational logic and the associated risks, which vary across different types [1] Group 1: Traditional vs. Decentralized Financial Systems - The global financial system is at a crossroads, with traditional banking systems showing high costs and low efficiency, while a decentralized wave driven by blockchain technology seeks to eliminate intermediaries [4] - The 2008 financial crisis led to a fundamental questioning of the need for intermediaries, giving rise to Bitcoin as a peer-to-peer transaction experiment [4] Group 2: Types of Stablecoins - Stablecoins are categorized into four main types: 1. Fiat-backed stablecoins, which are pegged to currencies like the US dollar at a 1:1 ratio [7] 2. Commodity-backed stablecoins, such as those pegged to gold, which can still experience price volatility [8] 3. Crypto-collateralized stablecoins, which use cryptocurrencies as collateral but often require over-collateralization to maintain stability [8] 4. Algorithmic stablecoins, which aim to maintain value through smart contracts and algorithms without any backing assets [8] Group 3: Market Dynamics and Challenges - The stablecoin market has seen significant growth, with a total market cap exceeding $300 billion as of mid-2025, and on-chain transaction volumes surpassing $8.9 trillion in the first half of 2025 [9] - A core challenge in the stablecoin market is the "impossible trinity," where achieving decentralization, price stability, and capital efficiency simultaneously is difficult [9] Group 4: Regulatory and Geopolitical Implications - Stablecoins, particularly fiat-backed ones, face risks related to centralization and trust in issuers, as demonstrated by the USDC crisis following the Silicon Valley Bank collapse [11] - The rise of stablecoins poses a threat to monetary sovereignty, especially in high-inflation countries where citizens prefer stablecoins over local currencies [12] - The U.S. has strategically mandated stablecoins to be pegged to the dollar, potentially positioning them as major holders of U.S. Treasury bonds by 2030 [12] Group 5: China's Strategic Response - China is exploring the issuance of offshore RMB stablecoins and has initiated the digital RMB project to maintain control over its monetary policy while leveraging blockchain efficiency [14] - A dual strategy of promoting both digital RMB and offshore stablecoins could enhance market applications and support international payment needs for SMEs [14]
