π¦ The Anatomy of a Wire Delay: Why Central Bank RTGS Halts
When you initiate a wire transfer at your commercial bank (such as JPMorgan Chase, Barclays, or Deutsche Bank), your bank does not immediately push physical currency to the recipient's institution. Instead, it dispatches an MT103 or ISO 20022 pacs.008 payment message to the sovereign central bank's Real-Time Gross Settlement (RTGS) system.
Settlement occurs only when the central bank debits the sending institution's reserve account and credits the receiving institution's reserve balance in central bank money. Because central bank reserve accounts require real-time liquidity monitoring, central banks enforce strict daily operating hours:
