ブルームバーグの重大予測：ステーブルコインの取引額が2030年に5.6兆ドルに達し、世界の決済システムを再構築

Bloomberg Industry Research’s latest forecast shows that by 2030, stablecoin payment transaction volumes are expected to surge to approximately $56.6 trillion, with stablecoins potentially evolving from crypto financial tools into one of the core payment infrastructures in the global financial system.

Data indicates that in 2025, global stablecoin payment transaction volumes reached approximately $2.9 trillion. To achieve $56.6 trillion within five years, stablecoin transaction volumes would need to maintain a compound annual growth rate of approximately 81%. Bloomberg believes the core driving force behind this high-speed growth comes from the continuous entry of institutional users and strong demand for USD stablecoins in certain countries and regions amid high inflation and currency depreciation.

In terms of specific structure, USDT and USDC present a clear divergence. Bloomberg points out that Tether-issued USDT dominates in centralized finance (CeFi) scenarios, widely used for daily payments, cross-border settlements, and fund storage; while Circle-issued USDC has greater advantages in the decentralized finance (DeFi) sector, being the most commonly used stablecoin in on-chain protocols and applications.

According to statistics from crypto data platform Artemis, stablecoin overall transaction volume grew 81% year-over-year in 2025. Among these, USDC’s annual transaction volume reached $18.3 trillion, higher than USDT’s $13.3 trillion. Despite this, from a market capitalization perspective, USDT remains in first place with a market cap of approximately $186.9 billion, while USDC stands at approximately $74.9 billion. The two combined account for over 95% of the approximately $33 trillion total stablecoin transaction volume last year.

On a macroeconomic level, adoption rates by countries and institutions are accelerating. After US President Trump signed the GENIUS Act in July, countries such as Canada and the United Kingdom have resumed advancing stablecoin regulatory frameworks, planning implementation around 2026. Meanwhile, payment giants like Western Union, MoneyGram, and Zelle are exploring blockchain-based stablecoin settlement solutions, with some systems to be deployed on high-performance networks such as Solana.

In summary, whether from transaction scale, institutional participation, or changes in regulatory attitudes, stablecoins are accelerating their transition from “crypto infrastructure” to “global payment layer,” with their role in the future financial system being repriced.
