Settle the difference, not the gross.
Multilateral netting compresses cross-subsidiary FX settlement volume by 60–85% versus gross settlement on representative books. This lab models a synthetic 4-subsidiary × 3-currency book, lets you switch between gross / bilateral / multilateral settlement modes, and surfaces the resulting savings in FX spread paid, nostro capital freed, currency-pair compression, and Herstatt-style settlement-risk reduction. Exports as an AP2 treasury-policy mandate the runtime can enforce on every netting cycle.
The BIS Triennial Survey 2022 measured global FX turnover at $7.5 trillion per day. CLS Bank — the central PvP settlement infrastructure — settles roughly 50% of eligible FX volume and is itself a netting service. The Bank for International Settlements identified FX settlement risk (the Herstatt-style "one leg settled, counterparty fails before second leg" exposure) as the largest residual systemic risk in its 2022 Statement on Settlement Risk. Basel III LCR treats nostro deposits at correspondent banks as level-1/level-2 HQLA depending on jurisdiction — freeing nostro capital via netting directly improves the institution's LCR ratio.
Who owes whom, by currency
Cell at row A, column B = subsidiary A owes subsidiary B in the selected currency, monthly aggregate (USD millions, FX-converted at internal rate). Diagonal is zeroed. Switch the currency tab to edit other-currency books.
Choose the netting mode
Gross settles every cell. Bilateral nets each pair (A→B − B→A). Multilateral nets each subsidiary to a single net position per currency vs. a netting centre.
