Your bank's compliance team has your license, your corporate documents and your business plan. Then comes the request that stalls more forex applications than any other: show us the flow of funds. Where does a client's money arrive, where does it sit, and how does it leave?
The reason is simple. A bank or EMI does not underwrite "a forex broker." It underwrites each stream of money the broker generates, and it decides account by account whether it understands the stream, can screen it and is willing to hold it. A broker that cannot draw that map in one page looks like a broker that has not thought about it.
This guide lays out the map. It covers the four flows every brokerage runs, where each belongs, what the EU rules say about client money, and the points where forex broker settlement banking tends to break first.
Direct Answer
A forex broker runs four money flows: client deposits, client withdrawals, liquidity-provider funding, and the firm's own operating cash. Client money must be segregated from firm money, and banks underwrite each flow separately. The core of any banking application is a clear map of which account handles which flow, in which currency, over which rail.
What Are the Four Money Flows in a Forex Brokerage?
Every brokerage, whatever its size or jurisdiction, moves money in four streams. They have different risk profiles, different counterparties and different rules, which is why they rarely belong in one account.
| Flow | Direction | Typical rails | Where it should sit | What breaks first |
|---|---|---|---|---|
| Client deposits | In | Cards, alternative payment methods, bank wires, crypto on-ramps | A collecting account, then promptly a client-money account | The acquirer or processor pauses settlement |
| Client withdrawals | Out | Return to the original method, bank wires | The client-money account | Payout limits or trapped liquidity |
| Liquidity and margin | Both | Multi-currency wires to liquidity providers or prime brokers | Firm funds in a dedicated account, unless your regulator permits otherwise | Corridor restrictions and correspondent screening |
| Operating money | Both | Wires, cards, payroll, local transfers | The operating account | The operating account closes because of one of the flows above |
A fifth movement sits between them: transfers from the client-money account to the firm's own account for earned fees and realized results. Regulators and banks both look hard at that step, because it is where client money and firm money touch.
What to Consider:
- One account per purpose. An account that does two jobs becomes an account that cannot be explained cleanly to an underwriter or an auditor.
- Currency by flow. Match account currencies to client currencies and liquidity-provider currencies, so conversions happen once and on purpose.
- A named owner per flow. Someone in the firm should own reconciliation of each account, not the finance team in general.
- Volumes you can defend. Expected monthly in and out per flow, by currency, is the first number a bank will ask for.
Final Takeaway: Draw the four flows before you approach any institution, and give each its own account, currency and owner.
Where Does Client Money Sit, and What Do the Rules Require?
In the EU, the starting point is MiFID II, Article 16(9): a firm holding client funds must make adequate arrangements to safeguard client rights and, unless it is a credit institution, prevent the use of client funds for its own account. The detail sits in Delegated Directive (EU) 2017/593.
Three of its requirements shape the banking structure. Records must distinguish each client's assets from other clients' and from the firm's own. The firm must reconcile its internal records against third-party records regularly. And client funds held at a credit institution or bank must sit in accounts identified separately from the firm's own.
Article 4 then restricts where client funds can go. On receiving client funds, a firm must promptly place them with a central bank, a credit institution, a bank authorized in a third country, or a qualifying money market fund. It must exercise due skill, care and diligence in selecting and periodically reviewing the institution, and it must consider the need to diversify the funds.
| Where client funds are held | Listed in Article 4(1)? | Practical note |
|---|---|---|
| Central bank | Yes | Rarely used by brokers in practice |
| Credit institution authorized under EU banking law | Yes | The usual home for a client-money account |
| Bank authorized in a third country | Yes | Relevant to non-EU structures where the regime allows it |
| Qualifying money market fund | Yes | Requires the client's explicit consent |
| Electronic money institution | No | Generally suits operating, settlement or payout flows, not client money |
That last row matters for planning. An EMI is not a credit institution, so under the EU rules a safeguarded EMI account is generally not itself an eligible home for client money, even though it can be very useful for other flows. Regulators outside the EU, including the offshore regimes that license brokers, set their own rules. Confirm in writing what yours accepts before you design the structure around it.
The UK has its own regime: the FCA's client money rules in CASS 7 set detailed requirements for holding and reconciling client money. For the practical side of segregated accounts, trust letters and reconciliation, see our guide to secure forex payment processing.
Reality Check
An account that is "segregated" in name only fails the first underwriting question. Banks and regulators do not ask what the account is called. They ask whether you can prove, today, that every cent in it belongs to clients and reconciles to your records.
What to Consider:
- Eligibility first. Check that the institution holding your client-money account is one your regulator accepts for that purpose.
- Diversification. The EU rules ask firms to consider spreading client funds, which is also the strongest argument for a second client-money institution.
- Prompt placement. Money that belongs to clients should not linger in a collecting or operating account longer than your rules allow.
- Written confirmation. Keep your regulator's or auditor's confirmation of the structure on file. Banks ask for it.
Example
A new brokerage kept client deposits and its own fee income in one account for its first quarter because reconciliation was manual. At its first audit it could not show which balances belonged to clients on three of the sampled days, and it had to separate the accounts and automate daily reconciliation before the audit closed.
Final Takeaway: Confirm what your regulator accepts as a client-money home before you build, because a structure that works commercially but fails eligibility has to be rebuilt.
How Do Card and Alternative-Payment Deposits Reach Your Account?
Most retail deposits arrive through a card acquirer or payment processor, which collects the funds and settles them to a registered account after a delay. Settlement commonly runs from one to several business days, and the account it settles into is a decision with regulatory consequences.
If the deposit is client money, it must reach a client-money account promptly. If your acquirer settles into an operating account, you need an orderly, documented and fast internal transfer. Many brokers design the opposite problem by accident: processor settlement lands in an account that is neither clearly operating nor clearly client money.
Then there is reserve exposure. A rolling reserve holds back a share of card volume for a set period against chargebacks. For a broker, that money is neither available operating cash nor sitting in the client account, so it has to be in your liquidity model from day one. The rolling reserve calculator shows how a reserve changes available cash, and our guide to forex merchant accounts covers reserves and licensing for this sector.
Chargebacks carry a forex-specific twist. A client who loses on a trade and then disputes the deposit as unauthorized creates a loss the broker carries. Processors watch this closely, which is why deposit dispute ratios belong in your internal dashboard before they appear in an acquirer's warning letter.
What to Consider:
- Settlement destination. Decide in advance where each rail settles and how fast funds move on to the client-money account.
- Reserve in the model. Include reserve holdbacks in your liquidity forecast, not just in your processor contract.
- Alternative methods. Local payment methods, wires and crypto on-ramps each have their own settlement account and screening profile.
- A second acquirer. Single-processor dependency is the most common way a settlement flow stops overnight.
Example
A mid-sized brokerage collected card deposits through one acquirer that settled into its operating account on a three-day cycle. When the acquirer paused payouts for a review, client withdrawals were still due, and the firm had to fund them from operating cash while 12 days of deposits sat in limbo. A second collecting rail and a defined internal transfer rule removed the dependency.
Final Takeaway: Decide where each deposit rail settles and how quickly it moves on, then put the reserve in your liquidity model.
What Happens on the Way Out: Withdrawals, Profits and Commissions?
Withdrawals are where regulators and banks look for money-laundering patterns, and the standard defence is the return-to-source principle: money generally goes back to the method and account it came from, up to the amount deposited, with profits routed through a verified alternative. That keeps outgoing flows explainable, and it limits chargeback exposure on cards.
Client withdrawals should be paid from the client-money account. Payments to introducing brokers and affiliates are different: they are the firm's own costs, paid from operating money, usually in many currencies and to many individuals across several jurisdictions. Banks treat that pattern with extra scrutiny, because it looks like a distribution network.
A bank taking on a broker is also assessing whether its correspondent banks will clear the pattern. Frequent, multi-currency, trading-related transfers can sit awkwardly against correspondent risk models, which is why some corridors are restricted even at banks that actively want forex business. Our guide to the forex company bank account explains the correspondent chain in detail.
What to Consider:
- Method match. Pay withdrawals back through the original deposit method wherever possible, and document the exception path.
- Commission payments. Keep partner and affiliate payments in the operating account, with contracts and screening files behind them.
- Corridors. Ask each prospective institution which currencies and countries it can clear without added friction.
- Payout capacity. Confirm payout limits and processing times before launch, not after the first large withdrawal.
Final Takeaway: Pay clients back through the route they came in on, from the client-money account, and keep commission payments in the operating account.
How Do Liquidity Providers and Margin Fit In?
Funding a liquidity provider or prime broker is a high-value, multi-currency transfer from the firm to a counterparty, and banks treat it as its own corridor. Margin is posted and returned as positions move, so this flow is lumpy and can be large relative to the rest of the business.
Whether margin for hedged client positions can be funded from client money depends on your regulator's rules, so confirm the position before designing the flow. In many structures the firm funds hedging from its own capital, which makes the operating or a dedicated treasury account the natural home for it.
Currency is the practical complication. Liquidity providers usually settle in a handful of major currencies, while clients fund in many. Every conversion adds cost, a screening step and a possible delay, so the cleanest structures convert once and hold the right currencies in the right accounts.
| Question | Why a bank asks | What a clear answer looks like |
|---|---|---|
| Which entity funds the liquidity provider? | To see who bears the counterparty risk | A named firm entity, funded from firm capital |
| In which currencies? | To assess corridors and conversion exposure | A short list matched to account currencies |
| At what size and frequency? | To size screening and limits | A monthly range with peak days explained |
| What happens if a transfer is delayed? | To judge continuity risk | A funded buffer and a second route |
What to Consider:
- Entity and capital. Fund the liquidity provider from the entity and capital your regulator expects, and document it.
- Currency match. Hold liquidity-provider currencies in accounts that need no extra conversion.
- A funded buffer. Keep enough cash to meet a margin call or a delayed transfer without touching client money.
- A second route. Confirm that another institution or corridor could carry a liquidity transfer if the first is delayed.
Example
A firm funded its prime broker from one multi-currency account that also handled client-withdrawal conversions. A delayed margin transfer in a currency it did not hold forced a same-day conversion at a poor rate and briefly pushed the operating balance below payroll needs. A separate liquidity account, pre-funded in two currencies, removed the pressure.
Final Takeaway: Treat liquidity funding as its own corridor with its own account and currency plan, and confirm margin rules with your regulator first.
Which Flows Break First, and How Do You Prevent It?
When a brokerage's banking fails, it almost never fails everywhere at once. One flow breaks and the others follow. Knowing the usual order lets you protect the weakest link first.
| Failure point | Typical cause | Prevention |
|---|---|---|
| Settlement stops | One acquirer or one collecting bank, then a policy change or review | A second collecting rail with real volume on it |
| Client-money breach | Commingling, late transfers or a reconciliation gap | Daily reconciliation and a named owner |
| Withdrawal delays | Cash trapped in reserves, holds or margin | A liquidity buffer and a reserve-aware forecast |
| Corridor restrictions | A correspondent bank refusing a currency or country | Multiple institutions with different corridor coverage |
| Operating account closure | Scrutiny of high-volume flows routed through it | Keep client and liquidity flows out of the operating account |
What to Consider:
- Rank your weakest link. For each flow, name the single institution whose decision could stop it.
- Test the failover. Move a small real volume through the backup rail on a schedule, so you know it works before you need it.
- Watch the early signals. Rising dispute ratios, reserve changes and payout delays usually appear before a closure.
- Write down the repair path. Decide who does what if a settlement account closes on a Friday afternoon.
Two of our anonymized cases show the repair side of this. In the segregated-accounts case, a regulated broker went live with a compliant segregation structure inside its regulatory deadline. In the settlement redundancy case, a broker running operating and client-money banking through one bank added a second relationship on separate rails in 27 days, before scaling its marketing.
Final Takeaway: Protect the settlement and operating accounts first, because they are the first to fail and the last thing you can afford to lose.
How Do You Present the Flow of Funds to a Bank or EMI?
Bring a one-page map and a short narrative. The map shows each account, its legal owner, its currency, its purpose, the rails that feed it and the rails that drain it. The narrative explains how money moves between accounts, who reconciles each one and how often.
What to Consider:
- Account register. A table of every account by entity, currency, purpose and institution.
- Flow arrows. Deposits in, withdrawals out, liquidity funding and operating costs, with approximate monthly volumes.
- Control points. Who approves transfers between client and firm accounts, and what evidence they keep.
- Evidence. Your regulatory confirmation of the client-money structure, the latest reconciliation report and processor statements.
The same file, prepared once, answers the questions that stall most applications. It also shows an underwriter that your compliance function owns the structure instead of discovering it during the review.
Final Takeaway: A one-page flow map and a short narrative answer more underwriting questions than a long business plan.
Conclusion: Draw the Map Before You Apply
A forex broker's banking is four streams of money with four different rules: deposits in, withdrawals out, liquidity funding and operating cash. The brokers that get banked cleanly give each stream its own account, currency and owner, and can show that on a single page.
The structure has to start from your regulator's client-money rules, because eligibility decides where client funds can sit. It then has to survive its first failure. Settlement and operating accounts fail first, so a second rail carrying real volume belongs in the design from day one.
A bank that can see the map, the controls and the backup is underwriting a business it understands. That is what moves an application from a polite decline to a serious review.

Frequently Asked Questions
Can a forex broker keep client money in an EMI account?
Under EU MiFID rules, client funds must be placed with a central bank, a credit institution, a third-country bank or a qualifying money market fund. An EMI is not on that list, so an EMI account generally suits operating or payout flows instead. Other regulators differ, so confirm in writing.
Where should card deposits settle?
That depends on whether the money is client money under your rules. Client funds must be placed in a client-money account promptly, so many brokers settle into a collecting account and transfer on quickly under a documented rule. Avoid settlement into an account that is neither clearly operating nor clearly client money.
How many bank accounts does a forex broker need?
At minimum, one operating account and one client-money account, usually separated by currency and purpose. Most brokers add a collecting account for processor settlement, a liquidity-funding account, and a backup institution so that one closure cannot stop the business. The right number depends on volumes, currencies and license conditions, not a fixed rule.
Why do banks ask for a flow-of-funds diagram?
Because they underwrite money movements, not company names. A diagram lets the bank check each flow against its screening, its correspondent coverage and its appetite. It also shows whether your compliance team understands and controls the structure, which is often the deciding factor when two files look similar on paper.
Does BankMyCapital hold or move client money?
No. We are not a bank, an EMI or a payment processor, and we never take custody of client funds. We assess your file, prepare it for underwriting, and match it to institutions whose appetite fits. We do not guarantee approval.
