The CCY State Chain

Canonical state numbering from quotation through consolidation appears across `/states/` reference tiles and the grid beneath; AccountCcy also publishes defined terminology where treasury and controllers collide.

Ordered below as custody checkpoints—not reranking authoritative accounting sequence—you trace meanings ERP postings confuse unless custody vocabulary disciplines interfaces among treasury, accounting, consolidation, and disclosure owners.

1. 1 · Transaction currency

   Names obligation denomination and measurable commercial duties encoded before postings stabilize ledger custody; dominates invoicing, contract clauses, AR/AP recognition debates. Mistaken for ERP account assignment or reporting narration early—obligation currency survives unchanged while custody hops distort reconciliation silently beneath dashboards.

   Reference: Transaction currency

2. 2 · Account currency

   Assigns ERP chart custody—balances reconcile inside subsystem postings bounded by configuration—not interchangeable with obligation denomination alone nor synonymous with ledger measurement conventions downstream.

3. 3 · Settlement currency

   Governs cash rails clearing counterparties—rates diverge from transactional obligation when corridors net differently; treasury proves settlement artifacts while controllers tie postings back to obligation currency where FX differences crystallize into realized outcomes.

   Reference: Settlement currency

4. 4 · Ledger currency

   Materializes entity trial-balance measurement where close discipline accumulates FX differences before translation refracts narratives outward; confusion with functional currency governance invites misaligned policy debates across controllers.

   Reference: Ledger currency

5. 5 · Functional currency

   Determines economic-environment measurement lens anchoring primary amounts before translation reshapes disclosure—distinct from ledger configuration artifacts yet tightly coupled inside SAP-class stacks and equivalents.

   Reference: Functional currency

6. 6 · Reporting currency

   Frames outward management, investor, or regulatory lenses—presentation choices can diverge sharply from ledger custody without naming where translation policy intervened; currency exposure narratives amplify when visibility layers detach from measurement lineage.

   Reference: Reporting currency

7. 7 · Currency translation

   Executes methodology converting measured results into presentation currencies—translation adjustments memorialize equity-side governance distinct from rate-driven restatements at period boundaries when teams mislabel translation runs as ‘just FX.’

8. 8 · FX revaluation

   Restates monetary balances still denominated foreign at period ends—period-end revaluation governs unrealized FX on open monetary items until settlement or derecognition shifts economics toward realized classification.

   Reference: FX revaluation

9. 9 · Audit reconstruction

   Terminal posture requiring replayable monetary paths governed by contiguous audit trails—rates, postings, reconciliations, subsystem extracts—so monetary reconstruction proceeds without heroic spreadsheets storytelling audit committees tolerate briefly.

   Reference: Audit reality

Treat transactional obligation currency as ERP account assignment—or reverse them—and reconciliation scopes detach before cash settles.

Treat ledger measurement currency as interchangeable with functional currency governance—or vice versa—and policy debates mis-target controls while postings obey opposing conventions.

Confuse revaluation mechanics, remeasurement populations, and translation methodology—classic vocabulary drift—and teams debate variance narratives disconnected from actual pipeline transforms.

Allow reporting currency narration to obscure earlier custody hops—management packs polish outcomes while auditors hunt lineage upstream.

Leave audit teams unable to reconstruct originating obligation currencies through settlements into postings—assurance escalates into qualitative storytelling instead of artifact replay.

Preserve numeric balances while shedding subsystem state context—values survive while forensic narrative collapses—the silent precursor to material weakness conversations.

Quoted currency precedes obligations commercially—anchor quotation discipline before transactional duties crystallize; consolidation currency still absorbs group reshaping prior to terminal audit posture across canonical `/states/` navigation.

Currency state vocabulary explains why ISO equality masks institutional inequality; account currency control names governance over custody assignments at State 04.
