Safeguarding Client Assets: Custody of Financial Instruments and the System Your Supervisor Expects

If your firm holds client financial instruments or funds, safeguarding is not a formality: it is a complete system of segregation, records, monitored sub-custodians and reconciliations, capped by the external auditor’s report. We help you build it and test it with evidence.

Four firms, four safeguarding problems

Custody breaks down in different ways depending on the model. These are the scenarios we review most often at investment firms, banks and platforms.

Broker-dealer

The broker-dealer with in-house custody and an international chain

“We hold assets in custody directly and use sub-custodians in three jurisdictions. Our challenge is proving that we monitor the whole chain: due diligence on every link, periodic review and reconciliations that match from end to end.”

Securities broker

The securities broker that deposits everything with a third party

“We don’t hold custody ourselves: the securities are with a custodian bank. We thought that took the burden off us, until we understood that selecting and periodically reviewing the sub-custodian is our obligation, with paperwork to prove it.”

Digital platform

The online broker operating through omnibus accounts

“All client activity runs through omnibus accounts at a foreign custodian. It works and it’s efficient, but we had to strengthen our internal records and reconciliations: if my records don’t say what belongs to each client, nobody does.”

EAF

The EAF that holds no custody (and must keep it that way)

“As an EAF we hold no client funds or securities: we advise, full stop. Our discipline is never to touch the money—not even a one-off transfer as a favor—because crossing that line would take us outside our license.”

The three pillars of safeguarding (and how they fail)

Almost every incident involving client assets can be traced to a failure in one of these three pillars. The supervisor knows this and looks precisely there.

Asset segregation: client instruments and funds must be kept separate from the firm’s own, so that the firm’s insolvency does not drag them down with it. Segregation is proven with an account structure and records, not with statements of intent.

Omnibus accounts under control: pooling client positions in global accounts is an accepted and common practice, but it shifts all the weight onto your internal records: if your client-level breakdown fails or does not reconcile, the omnibus account becomes an opaque box full of other people’s money.

Monitored third parties: depositing with sub-custodians requires due skill, care and diligence when selecting them—financial soundness, applicable legal regime, protection in their jurisdiction—and documented periodic review. Your responsibility to your client cannot be outsourced.

Three core safeguarding obligations: what is expected and what evidence proves it
Obligation What is expected Typical evidence
Segregate client assets Effective separation between the firm’s own assets and client assets, identifiable at all times and resilient to the firm’s insolvency Documented account structure, client-level internal records and clear designation of client accounts as distinct from proprietary accounts
Monitor the sub-custody chain Diligent selection of each third party and periodic review of its financial soundness, legal regime and service quality Due diligence files, sub-custody agreements, a review schedule and minutes with conclusions and measures
Reconcile at an appropriate frequency Regular matching of internal records against positions held at custodians, with investigation and resolution of differences Archived reconciliations, a log of discrepancies with their analysis, resolution deadlines and escalation of incidents

Put your safeguarding to the test before the supervisor does

We review your entire system—segregation, omnibus accounts, sub-custodians, reconciliations, consents to use assets—against what the CNMV expects to see, give you the gap map and close the gaps with you: policies, contracts, controls and support for the external auditor’s report.

Safeguarding client assets: questions firms ask us

What exactly is safeguarding of client assets?

It is the set of obligations that protects the financial instruments and funds that a firm (an investment firm, or a bank in its securities business) holds on behalf of its clients: keeping them separate from its own assets, recording them so that each position can be attributed to its owner, monitoring the third parties with which they are deposited and not using them for its own benefit without consent.

Its ultimate goal is simple: if the firm fails, client assets are identified, separate and recoverable.

What is an omnibus account and what are its risks?

It is a global account at a custodian in which the positions of several clients are pooled under the firm’s name. It is a common and accepted practice—especially in international custody—but it concentrates three risks:

  • Attribution: the custodian sees an aggregate balance; who owns what appears only in your internal records.
  • Knock-on errors: an undetected discrepancy affects every client in the account.
  • Jurisdiction: effective protection depends on the regime applicable to the foreign custodian.

That is why an omnibus account requires flawless records, robust reconciliations and adequate information to clients about this form of custody.

Can I deposit my clients’ assets with a third party?

Yes, and it is the norm: few firms physically hold the entire chain themselves. What you cannot do is wash your hands of it. When choosing a sub-custodian you must act with due skill, care and diligence: assess its financial soundness, its legal regime and supervision, the protection of assets in its jurisdiction and its operational capacity.

After that comes documented periodic review: due diligence is not a snapshot taken at signing, it is a film. The same logic applies as in outsourcing of critical functions, which we cover separately: the third party performs, you remain accountable.

Can the firm use clients’ securities for its own benefit?

Not without permission: using client financial instruments—for example, for securities financing transactions—requires the client’s prior express consent, which must be provable, and only under the conditions set by the rules.

The standard of evidence is high: specific, documented consent, not a clause lost on page forty of a master agreement. Using client assets without that consent is one of the breaches that hurts most in the eyes of the supervisor, because it strikes at the heart of trust in the system.

How often do you have to reconcile?

The rules require reconciliation at a frequency appropriate to the volume and nature of the business: an institutional business with few movements is not the same as a retail broker with thousands of orders a day. In practice, the more intense the activity, the more frequent the reconciliation.

What the supervisor expects to see in any case: systematic reconciliations between internal records and custodians, investigation of every difference, resolution deadlines and escalation of anything that does not match. An old, unexplained discrepancy is an immediate red flag.

What is the external auditor’s report on asset protection?

It is a specific report by the external auditor assessing the adequacy of the firm’s arrangements to protect client assets, on the terms set by the applicable rules. It does not replace your controls: it examines them from the outside.

Our advice is to treat it as an ally in your calendar: if you prepare your safeguarding with an eye on what the auditor will have to verify—segregation, records, reconciliations, consents—you reach the review with the work done and without awkward findings to explain to the CNMV afterward.

Do EAFs hold client assets in custody?

No. An EAF (financial advisory firm) advises: it holds no client funds or securities, and that is precisely one of the reasons why its structure and regime are lighter than those of a broker-dealer (sociedad de valores) or a securities broker (agencia de valores).

The practical consequence for an EAF is one of discipline: never receive money or securities from the client, not even instrumentally or “for convenience.” If your model needs to handle client assets, you don’t need better procedures: you need a different license.

What role does FOGAIN play in all this?

FOGAIN is the last safety net: it covers investors up to €100,000 per investor in the cases provided by law, typically linked to the firm’s insolvency when the assets cannot be returned.

But do not confuse the layers: well-executed safeguarding is the primary protection—the assets are kept separate and returned—and FOGAIN is the parachute for when everything else has failed. A sound custody system aims never to need the fund’s coverage.

How to build (or fix) your safeguarding system

The same method we apply to new firms and in reviews of firms already operating: first understand the flows, then lock down the structure, then prove that it works.

Phase 1

Map of assets and flows

We trace where client instruments and funds are at every moment: accounts, custodians, sub-custodians and jurisdictions. Without this map, any safeguarding policy is just words on paper.

Phase 2

Structure and contracts

We design the segregation (proprietary accounts versus client accounts, individual or omnibus), negotiate sub-custody agreements with the right protections and document the due diligence on each third party.

Phase 3

Controls and testing

We implement reconciliations with their discrepancy workflow, control of consents to use assets and reporting to governing bodies, and we prepare the firm for the external auditor’s report.

10-step safeguarding checklist

  1. Inventory of client assets: identify which client instruments and funds the firm holds, in which accounts and with which institutions they are deposited.
  2. Map of the custody chain: document every link down to the final depositary, including the applicable jurisdictions and legal regimes.
  3. Segregation structure: clearly separate proprietary accounts from client accounts, and define when you use individual accounts and when omnibus accounts.
  4. Internal records: make sure your client-level breakdown lets you attribute every position at all times, including within omnibus accounts.
  5. Sub-custodian due diligence: assess the financial soundness, supervision, asset protection and operational capacity of each third party before depositing.
  6. Periodic review of third parties: schedule the reassessment of each sub-custodian and document conclusions and measures in minutes.
  7. Reconciliations: match internal records against custodians at a frequency appropriate to your business, with a discrepancy workflow and escalation.
  8. Use of client assets: prohibit use for the firm’s own benefit by default and, where appropriate, obtain provable express consents.
  9. External auditor’s report: prepare the evidence the auditor will verify on asset protection and close findings before they escalate.
  10. Governance and reporting: bring safeguarding to the governing bodies: indicators, incidents and decisions documented in minutes.

If you are setting up the firm, build safeguarding into the application from the start with our investment firm authorization service. If you are already operating, we review it as part of your risk management framework under CNMV supervision.

Working glossary

The vocabulary of custody, without empty jargon

Nine terms that come up in every safeguarding review. If your operations team and your compliance team don’t use them the same way, that is your first gap.

SafeguardingConcept

Protection of client assets

A system of segregation, record-keeping, third-party monitoring and limits on use that protects client instruments and funds.

It is proven with evidence, not with manuals.
SegregationPillar

Yours and the client’s, kept apart

Legal and accounting separation between the firm’s own assets and client assets, resilient to the firm’s insolvency.

The account structure is its key proof.
Omnibus accountOperations

The pooled client account

An account at a custodian that pools the positions of several clients. Permitted, but it requires flawless internal records and reconciliation.

The custodian sees the total; you must see each client.
Sub-custodianThird parties

The next link in the chain

An institution where client assets are deposited. Selecting it requires due diligence; keeping it requires periodic review.

You delegate the deposit, not the responsibility.
Due diligenceSelection

The check before depositing

Assessment of the third party’s financial soundness, supervision, legal regime and asset protection before entrusting positions to it.

If it isn’t documented, it didn’t happen.

Reports from previous years, a findings remediation plan and minutes tracking closure.

Safeguarding governance

An identified responsible function, periodic indicators and genuine board awareness of incidents.

Appointment of responsible persons, a custody dashboard, committee minutes and documented escalations.

Signs that your custody would struggle in an inspection

None of these situations can be fixed the week before the supervisor’s visit. Spot them now and turn them into a work plan.

  • No one can sketch from memory the full custody chain down to the final depositary, jurisdiction by jurisdiction.
  • The due diligence on your sub-custodians dates from the year you hired them, with no documented reviews since.
  • There are recurring reconciliation discrepancies that are “regularized” without investigating the root cause.
  • The use of client securities relies on a generic clause in the master agreement, not on express consents.
  • The findings of the auditor’s latest report on asset protection are still open, with no plan or date.

Safeguarding client financial instruments and funds: obligations and supervisory practice

When an investment firm or a bank provides securities services involving client assets, it takes on a set of obligations that the MiFID II framework places among the most sensitive in the entire system: the safeguarding of client financial instruments and funds. The logic is one of insolvency protection and trust: client assets must be segregated, recorded in the client’s name in the firm’s books, deposited with monitored third parties and free from unauthorized use, so that a crisis at the firm does not turn into a loss for the client. Here we explain each piece and, above all, how to evidence it.

Asset segregation and records: the foundation of everything

The first obligation is structural: separate client assets from the firm’s own, with an account structure that identifies what belongs to whom and internal records capable of attributing every position to its owner at any time. This requirement becomes critical in omnibus accounts, where the custodian only sees an aggregate balance in the firm’s name: all attribution lives in your books. Omnibus arrangements are permitted and efficient, but the trade-off is flawless records, adequate information to clients and enhanced reconciliations. It is one of the areas we document when preparing the authorization of an investment firm with custody in its program of operations.

Depositing with third parties: sub-custodian due diligence and review

Depositing client assets with sub-custodians—often in international chains—does not transfer responsibility: the firm must select them with due skill, care and diligence (financial soundness, supervision, legal regime and protection of assets in their jurisdiction) and subject them to documented periodic review. On top of this come reconciliations between the firm’s own records and positions at custodians, at a frequency appropriate to the business and with a serious process for investigating discrepancies. The broker-dealer (sociedad de valores) with in-house custody and the securities broker (agencia de valores) that deposits with third parties share the same standard here: demonstrable oversight of the entire chain.

Use of assets, external auditor and guarantee net

Two limits complete the system. First, the firm cannot use client instruments for its own benefit without express consent, given in advance and provable, under the conditions set by the rules: a generic consent hidden in a master agreement does not meet the standard. Second, the system is verified from the outside through the external auditor’s report on asset protection, whose findings should be closed with a plan and a date before an inspection inherits them. And as a final layer, FOGAIN covers up to €100,000 per investor in the cases provided by law: the parachute that well-built safeguarding aims never to need.

And an important clarification: EAFs do not hold custody

This set of obligations does not extend to financial advisory firms: an EAF holds no client funds or securities; it only makes recommendations, and that absence of custody explains its lighter structure. The operating rule for an EAF is one of absolute hygiene: never accept cash or instruments from the client, not even in passing. If your business model needs to handle client assets, the answer is not to stretch the license but to step up—to a securities broker or a broker-dealer—with the safeguarding system designed from the application stage. We build that design into the risk management framework under CNMV supervision of every firm we work with.
