The seven triggers Banks freeze business accounts for seven repeatable reasons — an AML alert, activity that drifted from your onboarding profile, cash-heavy patterns, a sanctions screening hit, an ignored due-diligence request, third-party money in your account, or a court order. Almost none of them mean the bank thinks you're a criminal; they mean the machinery hit a pattern it must check and locked the account while it does. Knowing the triggers is most of the protection, because nearly all of them are avoidable — and the last one is survivable with structure. This is the banks edition of a question we've mapped for [fintechs](/blog/7-reasons-fintechs-freeze-accounts/) and [payment processors](/blog/processor-froze-funds-mid-project/): same underlying compliance engines, different institution around them — with different handles to pull. ## The seven triggers **1. An AML alert.** Transaction-monitoring software scores every movement against laundering typologies: rapid in-and-out transfers, round numbers cycling, sudden volume, corridors that don't fit the business. Score high enough and [the account locks](https://docs.fynex.ai/payments-api/v1/docs#tag/troubleshooting) while a human reviews — and if the review escalates, the bank may be [legally barred from telling you anything](/blog/fintech-froze-my-funds-what-to-do/) ("tipping off"). **2. Profile drift.** You onboarded as a £5k-a-month consultancy; you're now taking £60k project payments from abroad. The bank's model compares observed behaviour with the declared story — and drift *is* the signal, [exactly as it is for non-resident founders](/blog/banking-for-non-resident-founders/). Growth you never mentioned looks like an account being used for something new. **3. Cash-heavy patterns.** Cash businesses are legitimate; cash is also laundering's favourite input, so deposits that jump in size or frequency draw flags fast. Consistency and documentation (till reports, invoices behind the cash) are the counterweight. **4. A screening hit.** Your name, a director's, or — often forgotten — a *counterparty's* matches a sanctions or watch list, sometimes just fuzzily. One payment from a flagged payer can freeze the receiving account while it's untangled. **5. The ignored letter.** Banks periodically re-verify customers (KYC refresh). The request for updated documents arrives, lands in a spam folder or a to-do pile, the deadline passes — and the account is frozen not for suspicion but for *silence*, which compliance must treat as evasion. This is the most common self-inflicted freeze and the cheapest to prevent: answer immediately, completely, once. **6. Third-party money.** Other people's funds moving through your account — a friend's invoice collected "just this once", a director's personal flows mixed in — reads as money transmission or layering. [Client money deserves its own structure](/blog/how-nested-accounts-work/), not your operating account. **7. A court order.** Garnishments, freezing injunctions, tax authority orders — the one category where the bank has no discretion at all, and the resolution path is legal, not procedural. ## What actually helps, in order **Before:** keep the bank's picture current (tell them about the new market *before* the big payments land — [large inbound outliers are the classic trigger](/blog/bank-blocked-customer-payment/)); answer every document request as if it were payroll; keep flows clean and separated; document unusual money before it moves. **During:** respond to the information request completely and *once* — partial answers restart the queue; reroute incoming payments to another account immediately so new money doesn't pile into the frozen one; use the handles banks uniquely offer — a branch where documents can be presented to a human, a formal complaint, and ultimately the ombudsman or regulator. The [full rescue playbook](/blog/fintech-froze-my-funds-what-to-do/) applies to banks with those additions. **Always:** structure as if the freeze will come anyway. [The two-account rule](/blog/the-two-account-rule/) exists for precisely this: an operating layer for flow, a second institution for the vault, and [certainty about where every pound sits](/blog/where-your-money-sits/) — so one institution's review, however long, never decides whether wages clear. ## The structural note A bank freeze and a fintech freeze feel identical from inside — same silence, same templates — because the AML machinery is the same. What differs is what surrounds it: banks bring deposit insurance and formal recourse; a well-built operating layer brings speed, [multi-rail routing around the blockage](/features/payouts/), and — in Fynex's case — client funds safeguarded at an FCA-authorised EMI with **a named human and an appeal path** on any review, [not a black box](/blog/fintech-with-real-support/). The resilient setup uses both, and lets neither hold everything. Related: [how to actually choose a business bank account](/blog/best-business-bank-account/) applies this list as a selection criterion rather than a post-mortem. A frozen account is rarely an accusation. It's a question asked with the money locked — and the businesses that survive it comfortably are the ones who answered most of the questions in advance.
