Model the migration from SWIFT correspondent rails to tokenized A2A settlement — corridor by corridor.
An interactive simulator for multinational treasurers. Select a cross-border corridor, dial in your monthly flow, and watch the trapped working capital release into a waterfall. Compare nostro pre-funding economics against token-settled A2A on the same chart, with FX spread savings benchmarked to current 2026 corridor volatility.
STEP 01 Select Cross-Border Corridor
Each corridor carries embedded 2026 volatility, SWIFT spread, and tokenized A2A pilot pricing from the FX Hedge Optimizer dataset. Pick a lane to drive the rest of the model.
STEP 02 Dial in Flow Parameters
Monthly corridor flow, average pre-funding days, and pilot scope. Every figure on the page below recomputes live.
STEP 03 Trapped Capital Rescue · Waterfall
Starting from the nostro balance you pre-fund today, watch each component of the migration peel capital back to the corporate balance sheet.
STEP 04 Rail Comparison · SWIFT vs Tokenized A2A
Same flow, same corridor, same period — modeled across legacy correspondent banking and a tokenized A2A pilot.
STEP 05 FX Spread · 2026 Volatility Benchmarks
Per Tool 76's corridor dataset. Tokenized A2A compresses the FX spread by netting the conversion onto a single book — the chart below shows where the squeeze comes from.
Spread bars scaled to the SWIFT baseline for the selected corridor. Bps shown are all-in (mid-to-bid + fee load).

Trapped capital · Monthly corridor flow × (pre-funding days ÷ 30). This sits in the nostro / vostro account at the correspondent and earns nothing for the corporate.
Capital release · T+0 atomic settlement unlocks ~95% of the nostro float; T+1 net settlement releases ~70%. The residual is a working buffer for retries and exceptions.
FX spread savings · (SWIFT spread bps − Token spread bps) × annual corridor flow at pilot scope. Spread vintages are 2026 corridor-level all-in marks.
Annual P&L lift · Released capital × cost-of-capital + (SWIFT fees − A2A fees) + FX spread savings. Annualized at 12× monthly cadence.
