Prediction surface
Tell me what happens next, and what to do about it.
The tape desk, the hub exchange board and the corridor pricing ledger each reported a table of what had already happened. Folded into this one surface they answer the only question a treasury asks: how long will this take, what will it cost, what can move against me, and what should I do first. Every number carries a p50, a p90, the drivers behind it and the manual-desk comparator — and the three reporting desks now live behind the forecast, as evidence for it rather than as work of their own.

Charges model: AD Category-1 margin of 5–22 bps by corridor depth, correspondent ₹1,850 and cable ₹1,100 per instruction and a simplified 18% GST assumption on modelled bank charges, not a bank quote or actual FX GST determination. Investment principal carries no generic withholding. Income tax applies only to the separately identified chargeable component; catalogued treaty ceilings require residence, beneficial ownership, applicable documentation and treaty/PPT/LOB review. Uncatalogued countries or unconfirmed entitlement remain unpriced, not tax-free. Rates are reference scenarios, not certified current-law tax advice. Saved older investment cases are recalculated without the legacy principal tax; their FX stamps are unchanged.
