On one side sit the central bank digital currencies. The PBoCs e-CNY has crossed `1.8조 위안` in cumulative volume; the Bank of Korea is running Phase 2 of its CBDC simulation with 100 citizens; the BOJ has wrapped Phase 3 of its digital yen pilot. The ECB is in the Preparation Phase for the Digital Euro (2025-2027) and the Fed has anchored FedNow as a 24/7 RTP rail while making clear it lacks the statutory authority to issue a digital dollar. On the other side sit private stablecoins. USDC, USDT, PYUSD, DAI, GHO, and FDUSD together exceed `$170B` in market cap; details like MiCAs EUR-denominated cap, USDCs T-bill reserves, USDTs redemption tantamount, and PYUSDs ERC-20 issuance are reshaping market structure. BIS Project Agora is wiring up multi-CBDC settlement that bridges wholesale CBDC with tokenized deposits; Project mBridge has demonstrated atomic settlement between four central banks. This piece walks the 2-tier CBDC architecture, e-CNY intent-based payments, MiCA stablecoin rules, Koreas Virtual Asset User Protection Act, and Japans PSC license (Mizuho, SBI, MUFG) in one coherent map.

PBoC e-CNY는 누적 거래액 `1.8조 위안`을 넘었고, 한국은행은 시민 100명을 대상으로 CBDC 모의실험 2단계를 진행 중이며, BOJ는 디지털 엔 실증실험 Phase 3을 마쳤다. ECB는 Digital Euro의 준비 단계(Preparation Phase)를 2025-2027년에 운영하고, Fed는 FedNow를 RTP 인프라로 안착시키되 디지털 달러는 입법 권한이 없다. 다른 한쪽에는 민간 스테이블코인이 있다. USDC·USDT·PYUSD·DAI·GHO·FDUSD를 합한 시가총액이 `$170B`를 넘었고, EU MiCA의 EUR-denominated cap·USDC reserve composition·USDT redemption·PYUSD ERC-20 발행 같은 디테일이 시장 구조를 바꾸고 있다. BIS Project Agora는 wholesale CBDC와 토큰화 예금을 잇는 multi-CBDC 결제 인프라를, Project mBridge는 4개국 중앙은행이 직접 결제하는 atomic settlement를 검증했다. 이 글은 CBDC 2-tier 아키텍처, e-CNY·디지털 위안의 인텐트 기반 페이먼트, MiCA 스테이블코인 규제, 한국 가상자산이용자보호법·KRW 스테이블코인 논의, 일본 PSC 라이선스(Mizuho·SBI·MUFG)를 한 호흡으로 정리한다.
