In plain English: ISO20022
The new messages remove the shadows where sloppy reporting, hidden fees, miscoded transfers, and “creative accounting” once lived.
That part is absolutely fair discernment.
But here’s the even bigger point
ISO 20022 doesn’t directly expose fraud —
it forces the systems that receive the data to expose it.
Under MT, a message might say only:
“Funds transfer - details on file.”
Under ISO 20022, the same transaction must specify:
• exact source of funds
• exact economic purpose
• exact ownership structure
• exact intermediary chain
• exact fees, spreads, FX rates
• exact regulatory category
• exact counterparty information
Machine-readable → machine-auditable → machine-reconcilable.
The opacity dies, not because ISO 20022 accuses anyone,
but because everything is finally described in forensic detail.
This is the transparency upgrade.
This blows open hidden flows, skimming, off-ledger pools, errors, mismatches, misallocated collateral, etc.
Banks, correspondent networks, FX desks, and clearing houses have relied for decades on:
• omnibus accounts
• blended fee buckets
• net-settlement “smoothing”
• miscoded purpose fields
• internal suspense accounts
• delayed reconciliation
ISO 20022 wipes out the shadows where these techniques lived.
Not by accusation - but by precision.
The post-cutover world becomes deterministic, not probabilistic
Under MT:
“Trust us, it balances.”
Under ISO 20022:
“Prove it. Every field. Every hop. Every custodian. Every fee. Every spread. Every timestamp.”
This is an audit-grade digital paper trail.
The only ones who fear this level of illumination are those who depend on opacity.
