Payment Clearing System
A payment clearing system is the infrastructure and set of rules that facilitate the exchange of payment instructions between banks and the settlement of the resulting obligations. Clearing systems ensure that when you send money from one bank, it reliably arrives at another.
Clearing systems operate in two stages: clearing (exchanging and validating payment instructions between banks) and settlement (transferring the actual funds, typically through central bank accounts). Some systems settle in real time (RTGS), while others batch transactions and settle at fixed intervals. In the US, ACH processes batch payments, while Fedwire handles real-time high-value transfers. In the UK, BACS handles batch processing and CHAPS provides same-day RTGS settlement.
The clearing system a payment travels through determines its speed, cost, and finality. Understanding clearing systems helps you choose the right payment method: batch systems like BACS and ACH are low-cost but slower, while RTGS systems like CHAPS offer immediate finality at a higher fee. Each system also has its own rules for dispute resolution and refunds.
