The rule.
Section 21 of the Financial Services and Markets Act 2000 restricts who may communicate a financial promotion — an invitation or inducement to engage in investment activity. Since October 2023, qualifying cryptoassets are controlled investments, so crypto marketing aimed at UK consumers is a financial promotion. The format is irrelevant: the rule turns on what is being communicated, not on whether it is called “sponsorship,” “a partnership,” or “an ambassador deal.”
“We have seen an increase in football club partnerships with unauthorised firms, some of which appear to be operating unlawfully … a number of unauthorised firms, including crypto businesses, are using sponsorship to target consumers.”
Paraphrasing the FCA’s June 2026 press release and letter to clubs. The FCA flagged legal liability, money-laundering and reputational risk, and said it expects clubs to conduct due diligence on financial-services sponsors before signing and on an ongoing basis.
The commercial backdrop is why the FCA moved: crypto and blockchain firms spent a reported £130m on Premier League sponsorships last season, with 14 of 20 top-flight clubs carrying a crypto or blockchain partner — up from eight a year earlier. A live World Cup multiplies the reach of every one of those assets. The perimeter does not relax for a tournament; it is tested hardest during one.
When a partnership crosses the perimeter.
Not every sponsorship is a financial promotion. The question is whether the asset contains an inducement to engage in investment activity. Use the substance test, surface by surface.
Likely inside the perimeter. A shirt, board or social post that pairs the sponsor’s brand with a call to act on a cryptoasset — “trade,” “buy,” “earn,” a token ticker, an app-download CTA, a referral or sign-up offer, or a QR code that lands on a buy/trade page. The fan is being moved toward investment activity.
Often a grey zone. A bare logo with no claim and no call to act. It may still be a financial promotion if the surrounding context (the landing experience a fan reaches, the social copy around it, the ambassador’s message) supplies the inducement. A logo is rarely sponsored in isolation — trace the journey it opens.
Outside the perimeter. A genuine non-financial product or a pure brand placement with no inducement to invest and no funnel into one. The further the asset sits from a buy/trade/earn action, the safer it is.
Who carries the liability.
The most common misconception is that only the financial firm is exposed. Section 21 catches whoever communicates the promotion — and a sponsorship deal usually has three hands on it.
The crypto firm (the sponsor).
If the firm communicates, or causes to be communicated, a financial promotion to UK consumers without being authorised, having its content approved by an authorised person, or fitting an exemption, it breaches Section 21. Communicating an unlawful promotion is a criminal offence under FSMA s25, carrying up to two years’ imprisonment and an unlimited fine. The February 2026 FCA High Court action against HTX, an offshore exchange targeting UK users, shows reach into the UK matters more than where the entity sits.
The club or rights-holder.
A club is not a passive billboard. When it posts the sponsor’s message, displays the asset, or lends its owned channels to the promotion, it can itself be a communicator inside the perimeter. Beyond Section 21, the FCA’s June 2026 letter spells out the wider exposure clubs accept by signing an unauthorised financial sponsor: legal liability, money-laundering risk, and reputational damage — with due diligence expected before signing and on an ongoing basis.
The agency or intermediary.
An agency that produces, places or activates the campaign can also be communicating the promotion. “We were only running the creative” does not move the liability elsewhere if the agency’s hands are on the asset that reaches UK fans.
Common patterns.
“It’s just a logo on the board — that can’t be a financial promotion.”
The logo is the entry point to a funnel that ends on a buy/trade page. The perimeter follows the inducement, not the pixel. Trace where the asset sends the fan before assuming it is outside scope. Citation: FSMA s21; PERG 8.
A non-UK exchange sponsors a UK club and runs UK-targeted matchday social with a sign-up offer.
Being incorporated offshore does not place the promotion outside the UK perimeter when it is communicated to UK fans. Reach beats entity location. Citation: FSMA s21(3); PERG 8.
A club ambassador posts “proud to partner with [token] — download and trade” to a UK following.
An individual communicating an inducement to invest is inside Section 21 too. The personal-account framing does not lift the post out of the perimeter. Citation: FCA finfluencer guidance; FSMA s21.
The deal is signed and live; nobody has identified which Section 21 gateway the promotional assets rely on.
If the sponsor is not authorised, the content is not approved by an authorised person, and no exemption genuinely applies, there is no lawful gateway — the assets should not run to UK consumers. Citation: FSMA s21(2); COBS 4.12A.
How to structure a compliant partnership.
Before signing, confirm the firm’s status: is it FCA-authorised with the relevant permission, or does it have an authorised person ready to approve its promotions for cryptoassets specifically? MLR registration is not authorisation for financial promotions. Re-check on an ongoing basis, as the FCA expects.
List each asset — shirt, board, programme, club socials, ambassador posts, hospitality, app placements — and decide, surface by surface, whether it carries an inducement and which lawful gateway it relies on (authorised, approved, or genuinely exempt). Surfaces with no clear gateway should stay brand-only or not run.
Where a promotion is approved, the visible approval marker — approver name and FCA reference — must appear on the asset itself. An approval you cannot see on the shirt, the post or the landing page is, for enforcement purposes, not there.
Put compliance warranties, an indemnity, status-change notification and a kill-switch into the sponsorship contract, and brief the agency and any ambassadors on what they can and cannot say. The contract does not remove the club’s communicator exposure, but it forces the diligence and creates the audit trail.
If the sponsor cannot clear a UK gateway, keep the promotional assets out of the UK in substance — not just a line in the terms. That means UK-targeting exclusions on paid and social, no UK-language calls to invest, and ambassador-contract restrictions, not a “UK users excluded” disclaimer over a UK-facing campaign.
