How the World Handles Payments: A Deep Dive into Global Clearing Systems
This article explores the architecture of global payment clearing, detailing the roles of SWIFT, CLS, and national systems across China, Hong Kong, the United States, Europe, the UK, Japan, Singapore, Korea, Russia, Australia, Mexico, Brazil, and the emerging multilateral CBDC bridge mBridge, illustrating how payments flow and settle worldwide.
01. SWIFT – Global Bank Financial Telecommunication Association
In cross‑border payment scenarios, transaction information must travel through multiple institutions. SWIFT acts as the core hub, routing messages between banks, agents, and intermediaries, making it essential to understand its basic principles for international settlement.
02. CLS – Continuous Linked Settlement
CLS, launched in 2002 by a consortium of major banks, provides payment‑versus‑payment (PvP) settlement for foreign‑exchange trades. It ensures that funds are exchanged only after both parties have fulfilled their obligations, supporting over 70 members and 18 currencies with daily transaction volumes exceeding $6 trillion.
03. Main Dual‑Track Domestic and International Clearing Systems
Both domestic and cross‑border payments follow a two‑track clearing model: a domestic clearing layer and an international clearing layer, each operating independently yet interconnected.
04. China Payment Clearing System
China’s system consists of a domestic clearing network (e.g., NetClear, UnionPay) and a cross‑border network (CIPS). The core settlement point is the People’s Bank of China’s second‑generation system (CNAPS). Domestic clearing is handled by entities like NetClear and UnionPay, while final settlement occurs at the central bank.
RMB cross‑border payments are processed through CIPS, with settlement completed in CNAPS.
05. Hong Kong Payment Clearing System
Hong Kong’s CHATS comprises four real‑time gross settlement (RTGS) systems for HKD, RMB, USD, and EUR, plus a central securities settlement system (CMU). It also includes the Faster Payments System (FPS) for retail transactions.
06. United States Payment Clearing System
The U.S. system is highly layered, featuring large‑value systems (CHIPS, Fedwire) and retail systems. CHIPS handles most dollar cross‑border clearing, while Fedwire processes domestic fund transfers. SWIFT carries messages, CHIPS clears, and Fedwire settles.
07. European Union Payment Clearing System
The EU operates several systems: TARGET2 for large‑value payments, SEPA for retail euro transfers (including SCT, SCT Inst, and SDD), and T2S for securities settlement, all interconnected with CLS for cross‑border FX.
08. United Kingdom Payment Clearing System
The UK uses CHAPS for high‑value sterling payments, Bacs for batch retail transfers, and FPS for 24/7 real‑time retail payments. A prefunded net‑settlement (PNS) mechanism ensures funds are posted before clearing, reducing credit risk.
09. Japan Payment Clearing System
Japan’s system is led by the Bank of Japan (BOJ‑NET) for large‑value yen transfers, the Foreign Exchange Yen Clearing System (FXYCS) for cross‑border yen, and the Zengin System for retail payments. The JPNS network provides 24‑hour instant yen transfers.
10. Singapore Payment Clearing System
Singapore’s infrastructure includes the large‑value MEPS+ system and the FAST/PayNow retail network, complemented by GIRO and cheque processing, covering all payment scenarios.
11. Korea Payment Clearing System
Korea’s system, overseen by the Bank of Korea (BOK‑Wire+), combines real‑time gross settlement for large‑value transfers with HOFINET for small‑value payments and a 24/7 instant transfer service.
12. India Payment Clearing System
India’s system is driven by the Reserve Bank of India (RBI) and the National Payments Corporation of India (NPCI). It features RTGS for large payments, UPI for instant retail transfers, and CCIL for securities and FX clearing.
13. Malaysia Payment Clearing System
Malaysia’s system, managed by Bank Negara Malaysia, centers on RENTAS for large payments and DuitNow for retail transfers, with IBG for inter‑bank batch processing and FPX for online payments.
14. Russia Payment Clearing System
Russia’s system, led by the Central Bank, includes SPFS as a Swift alternative, BESP as the RTGS platform, and ongoing CBDC pilot projects linked to BRPS.
15. Australia Payment Clearing System
Australia employs a “central bank regulation + industry self‑governance” model. The Reserve Bank of Australia oversees core RTGS (e.g., BESP) while AusPayNet operates retail systems like BECS and the New Payments Platform (NPP).
16. Mexico Payment Clearing System
Mexico’s system, governed by Banxico, combines RTGS (SPEI, DALI) with retail solutions (CoDi, CCEN) and market‑based card clearing (E‑GLOBAL). FX settlement relies on CLS and SPID.
17. Brazil Payment Clearing System
Brazil’s infrastructure, supervised by the Central Bank, features the STR RTGS for large payments and PIX for instant retail transfers, handling billions of transactions daily.
18. mBridge – Multilateral CBDC Bridge
mBridge, a joint initiative by the BIS and several central banks, uses a permissioned Hyperledger Besu blockchain to enable cross‑border CBDC transfers with minute‑level settlement and reduced fees, employing smart contracts and zero‑knowledge proofs for privacy.
