Decoding the advertising rulebook that governs bank promotions

In 2019 Revolut ran a poster reading "To the 12,750 people who ordered a single takeaway on Valentine's Day. You ok, hun?" The ASA banned it. Offence was part of the complaint, but the ruling turned on something duller: Revolut could not show the figure came from its own transaction data. One unverified number inside a joke, and the campaign came down with a published ruling that anyone can still find by searching the brand.

That is the pattern worth studying. Campaigns rarely die because someone lied about a rate. They die because a claim had no file behind it, because a tone was wrong for the product, or because the firm was not entitled to make the communication at all. This lesson covers what makes a communication a financial promotion, who may lawfully issue one, what the clear, fair and not misleading test actually asks, and the recurring shapes in published rulings.

What counts as a financial promotion

A financial promotion is any communication that invites or induces someone to engage in a financial product or service. The trigger is the invitation, not the format or the budget behind it. In the UK the concept sits in section 21 of the Financial Services and Markets Act 2000 (FSMA) and is policed by the Financial Conduct Authority (FCA). The US has no single label: bank advertising is governed by a stack of rules from the CFPB, the Federal Reserve and the FTC. In the EU, consumer-credit advertising falls under the Consumer Credit Directive.

The perimeter is wider than most marketing teams assume. Cases that catch people out:

• A retweet, share or quote-post from the brand account is a fresh communication in its own right, with the same obligations as the original.
• Image-only posts and short video with no spoken claim still count. A screenshot of an in-app rate is a rate claim.
• "Not financial advice" in an influencer caption removes nothing. Payment or free product makes the post the firm's promotion.
• A shirt-sleeve logo on its own is usually not an inducement. The same logo next to "0% for 12 months" is.
• Referral mechanics count. "Invite a friend, you both get 50" invites engagement with the product.

The two triggers to watch

1. You name a product benefit (a rate, a reward, a "free" perk). This pulls in disclosure rules.
2. You imply a comparison or certainty ("best", "guaranteed", "lowest fees"). This pulls in substantiation rules: you must be able to prove it, and prove it before the ad runs.

Who is allowed to issue one

Under section 21 FSMA, an unauthorised person cannot communicate a financial promotion in the UK unless an authorised firm has approved it or an exemption applies. Breach is a criminal offence carrying up to two years' imprisonment. For a licensed bank this looks like a formality. For everyone the bank works with, it is not.

Since 7 February 2024 an FCA-authorised firm cannot approve promotions for unauthorised third parties unless it holds a specific approver permission. The second-order effect landed on marketing teams rather than lawyers: partner, affiliate and comparison-site copy that a bank's compliance function used to wave through as a courtesy now needs a permission the bank may never have applied for. Distribution partnerships have been paused for exactly this reason, and the honest answer to "can you sign off our landing pagelanding pageA standalone web page built for a single campaign goal, designed to maximise conversions by removing distractions and focusing visitors on one action.View full definition →?" is now often no.

Status claims are the other half of the question. Chime, a US fintech rather than a bank, settled with California's Department of Financial Protection and Innovation in 2021 over marketing that presented it as a bank; it agreed to stop describing itself that way and to make clear that banking services come from its partner banks. The lesson generalises: saying who you are is itself a regulated claim, and "we work with a bank" and "we are a bank" are not the same sentence.

Perimeter also moves. Klarna's core pay-in-three product sat outside FCA regulation for years under an exemption for short-term interest-free credit, which meant its advertising was policed mainly by the ASA under the CAP Code rather than by the FCA rulebook. That gap is being closed as buy-now-pay-later is brought into FCA scope. Any team relying on "we are out of scope" should treat that status as a dated fact, not a permanent one.

The clear, fair and not misleading test

This is the FCA's literal standard and the spirit of every other regime. It is three separate questions, and creative usually fails one, not all three.

Clear is about comprehension by the actual audience, not by a lawyer. Reading age, contrast, exposure time on a six-second pre-roll.

Fair is about balance: benefit and cost visible in the same glance, with the qualifier no less prominent than the claim. Fairness in the wider sense of good outcomes and vulnerable audiences is the fair-treatment lesson's territory, and the campaign-side suppression machinery belongs to the consumer-protection lesson; here, treat balance as a layout and prominence test on the asset in front of you.

Not misleading is judged on overall impressionimpressionThe total number of times an ad or piece of content is displayed, regardless of clicks. Each display counts as one impression, even to the same person.View full definition →. An ad can be literally true in every clause and still fail, because the headline promises a rate that few applicants get, or because a lifestyle image implies a product does something it does not. Substantiation must exist before publication: a document, dated, held on file, that a regulator can be handed the same day it asks. Retro-fitting evidence after a complaint is itself an admission.

How the rate or fee text is then built (headline versus representative example, fee tables, eligibility caveats) is the disclosure-construction lesson's job, and this walkthrough covers the US mechanics:

Ruling patterns that pull campaigns

Published rulings repeat themselves. Four shapes account for most of the damage.

The number nobody can source. The Revolut takeaway poster is the clean case: a specific statistic, presented as customer data, with no evidence behind it. Marketing treated it as a bit of copy; the ASA treated it as a factual claim. If a figure appears in an ad, someone must own the file that produced it.

Tone that is wrong for the product. In December 2020 the ASA banned four paid Instagram posts from influencers for Klarna that connected buying clothes on credit with lifting your mood during lockdown. Nothing in them was factually false. They were ruled irresponsible because they encouraged credit use as an emotional fix. Credit advertising is held to a standard of tone, not only accuracy, and the tighter the audience's finances, the tighter that standard gets.

Saying you are something you are not. Bank, insured, regulated, protected. This is the Chime pattern, and it also covers deposit-insurance implications: referencing coverage you hold through a partner is permissible if stated precisely, while implying the entity itself is insured is not.

Superlatives with no dated file. "Best", "market-leading", "lowest fees", "the UK's number one". Substantiation must match the exact wording and the exact date range the ad ran. A comparison assembled from a rate table pulled the week after the complaint arrives does not save the claim.

The finfluencer variant sits across all four. The FCA interviewed 20 finfluencers under caution in October 2024 and has issued alerts against accounts promoting financial products without authorisation. When money or product changes hands, the creator's post is the bank's promotion, carrying the same qualifiers and warnings, and "just sharing my opinion" is not a defence.

What a withdrawal actually costs

The ASA cannot fine anyone, which leads some teams to underprice its rulings. The costs are elsewhere. The ruling is published, permanent and searchable, and it names the brand next to words like "irresponsible" or "misleading" for as long as the internet remembers. Media owners and ad platforms can refuse the creative, and the CAP compliance route can have paid search ads taken down. The FCA and Trading Standards can be handed the file.

Internally the bill is the sweep. One withdrawn tagline is never one asset: it is every size variant, the app store copy, the affiliate pack, the email footer, the sponsored podcast read already recorded, and the same claim sitting in three other markets.

Scale explains why regulators can afford to be blunt: the FCA has reported roughly 10,000 promotions amended or withdrawn at its request in a single year. Your campaign is not a special case being singled out; it is one line in a quarterly count.

Common failure modes, in the order they show up in reviews:

• A statistic in a headline with no dated source file.
• Comparative claims substantiated after publication rather than before.
• Third-party or affiliate copy issued without a valid approval route.
• Status wording that implies the entity is a bank or is insured when the partner is.
• Credit messaging whose tone treats borrowing as a mood repair.

Key takeaways

• A communication becomes a financial promotion when it invites or induces engagement with a product. Format, budget and channel are irrelevant, and a share or a referral prompt counts.
• Who may issue matters as much as what it says. Section 21 restricts communication, breach is criminal, and since February 2024 approving an unauthorised partner's promotion in the UK needs a specific FCA permission.
• Clear, fair and not misleading is three tests. Comprehension, prominence balance, and evidence held before publication. Overall impression governs, so a technically true headline can still fail.
• Rulings repeat: unsourced numbers, irresponsible tone on credit, status misrepresentation, and superlatives without a dated file.
• The expensive part of a withdrawal is the permanent published ruling plus the sweep across every asset that reused the claim.
