Direct answer

What the evidence supports

Client-money segregation is the legal and operational separation of client funds from the firm’s own money under the rules that apply to the firm, product, account, and jurisdiction. Technology supports this obligation by classifying accounts and transactions, maintaining complete ledgers, reconciling internal records to banks or custodians, controlling transfers, recording acknowledgements and approvals, detecting shortfalls or excesses, escalating exceptions, and preserving an audit trail. Software does not create regulatory permission or replace the responsible firm’s judgment.

A reliable design begins with the applicable rulebook and legal account structure, not with a generic “segregated” checkbox. Map every deposit, withdrawal, fee, trade cash flow, margin movement, interest item, chargeback, reversal, transfer, currency conversion, correction, and insolvency-relevant record. Define internal and external reconciliation methods, frequency, cut-off, source systems, responsibility, tolerance, shortfall funding, approval, notification, retention, and business-continuity procedure.

Original control example

Client-money resource reconciliation trace

The applicable legal calculation must come from qualified advisers and the relevant rules. This simplified trace only illustrates exception handling.

Internal requirement

Complete client-level records total $2,400,000 at the documented cut-off after valid postings, currencies, fees, and adjustments are normalized.

External resource

Designated external accounts total $2,380,000. A validated $15,000 timing item is separately evidenced and due within the approved process.

Unexplained difference

$2,380,000 + $15,000 − $2,400,000 = −$5,000. Escalate, fund, investigate, correct, approve, and retain the evidence required by the applicable regime rather than hiding the shortfall inside tolerance.

Client-money, safeguarding, custody, margin, and payment-services regimes differ. Do not use this arithmetic as a legal calculation or substitute it for current rules, permissions, account acknowledgements, and counsel-reviewed procedures.

Technology requirements for client-money controls

The exact requirement differs by regulatory regime, but the control design should make classification, movement, reconciliation, and exception handling explicit.

Client and account classification

Store legal entity, jurisdiction, client category, product, account status, protection treatment, currency, bank or custodian, trust or statutory designation, contractual terms, and effective dates. Changes need approval and history.

Complete books and records

Maintain client-level entitlements and transaction history with balanced entries, value and booking dates, source references, currency, fees, corrections, and links to bank, custodian, payment, trading, and general-ledger records.

Controlled money movement

Enforce permitted source and destination accounts, verified beneficiary changes, dual control where required, limits, sanctions or fraud holds, release approval, payment status, rejection, recall, reversal, and immutable audit history.

Internal and external reconciliation

Implement the regulator-approved or counsel-reviewed calculation using complete source records and defined cut-offs. Distinguish timing differences from breaks and retain the inputs, output, reviewer, and corrective action.

Shortfall, excess, and incident handling

Set materiality and escalation without using tolerance to hide errors. Define funding authority, withdrawal of excess where permitted, investigation, senior notification, regulator or client communication, remediation, and recurrence prevention.

Design from rule to daily evidence

  1. 01

    Translate the legal model

    Qualified counsel and compliance owners identify applicable rules, permissions, exclusions, bank or custodian account structure, acknowledgements, calculation method, frequency, records, notifications, and responsible officers.

  2. 02

    Map every source and posting

    Trace payment providers, bank statements, wallets where permitted, trading accounts, margin, fees, commissions, adjustments, chargebacks, CRM, back office, subledgers, and general ledger. Assign authoritative source and owner.

  3. 03

    Build controlled reconciliations

    Validate source completeness, normalize identifiers and currencies, calculate required resources and records, match balances and transactions, classify exceptions, and prevent silent overwrite or unsupported netting.

  4. 04

    Review, fund, and certify

    Independent reviewers investigate breaks, approve corrections, arrange shortfall funding under documented authority, record any permitted excess transfer, certify completion, and escalate aged or material issues.

  5. 05

    Rehearse disruption and insolvency access

    Test missing statements, provider outage, incorrect file, cyber incident, staff absence, bank failure, platform recovery, record export, contact lists, and the ability to produce current client entitlements.

Control evidence to retain

Retention periods and exact records follow the applicable rules, but the evidence must support independent reconstruction and supervisory review.

Account and acknowledgement records

Keep bank or custodian account details, designation, trust or statutory acknowledgements where applicable, signatories, permissions, opening and closure, and periodic verification.

Daily source and calculation pack

Preserve source completeness checks, statements, ledgers, exchange rates, cut-off, calculation version, balances, matching output, exceptions, reviewer, certification, and timestamps.

Exception and correction trail

Record cause, client impact, amount, currency, age, owner, escalation, funding, accounting correction, approval, communication, closure, and prevention action.

Access and segregation-of-duties review

Evidence who can change bank details, classify clients, post journals, release payments, approve adjustments, run reconciliation, fund shortfalls, and certify completion.

Continuity and retrieval tests

Retain test dates, scenarios, source restoration, manual fallback, staff roles, recovery time, record integrity, export success, issues, and remediation.

Boundaries and limitations

  • Client-money, safeguarding, custody, margin, payment-services, and trust-account regimes are not interchangeable.
  • Applicability depends on the legal entity, permissions, product, client type, contract, flow of funds, and jurisdiction.
  • A label such as “segregated account” is not sufficient evidence; review the legal arrangement, bank acknowledgement, records, controls, and reconciliations.
  • RTX5 can support technology workflows only within an approved operating model; it does not provide legal authorization or regulator approval.

Questions readers ask

Does a segregated bank account prove compliance?

No. The firm also needs the correct legal designation, complete books and records, controlled movements, required calculations and reconciliations, shortfall procedures, governance, and evidence.

Can the trading platform balance be the client-money ledger?

Only if the approved design and applicable rules support it and it contains all required transactions and controls. Many firms need separate accounting or subledger records and external reconciliation.

Who is responsible when a vendor hosts the system?

Outsourcing can allocate operational tasks, but the regulated firm generally retains obligations and oversight. The contract and responsibility matrix should define data, access, incidents, evidence, continuity, and exit.
