Q01.How does CLS payment-versus-payment (PvP) eliminate Herstatt settlement risk?
CLS simultaneously settles both currency legs of an FX transaction across central bank accounts during a 5-hour CET window, ensuring neither counterparty releases principal unless the contra-currency leg is funded.
Q02.Why does a negative EUR/USD or USD/JPY cross-currency basis occur?
A negative cross-currency basis means non-U.S. institutions pay a premium beyond textbook covered interest parity to borrow synthetic USD via FX swaps, driven by offshore USD balance-sheet demand and quarter-end G-SIB constraints.
Q03.What is the standard settlement cycle for G10 spot FX pairs?
Most G10 spot FX pairs (including EUR/USD, GBP/USD, and USD/JPY) settle on T+2, whereas USD/CAD and USD/TRY settle on T+1.
Q04.How is the 4pm London WM/Refinitiv FX Fix calculated?
The WMR 16:00 London Fix captures executed trades and top-of-book quotes over a 5-minute window (+/- 2.5 minutes around 16:00 UK time) across primary interdealer matching venues and computes a median mid-rate.
