A warning nobody can read is not a warning.

COBS 4.12A.37G and 4.12A.41G: design crypto risk warnings to WCAG and give them in another language where recipients may not read English well.

United Kingdom FCA COBS 4.12A.37G · 4.12A.41G

The rule.

FCA Handbook, COBS (as amended by the Cryptoasset Financial Promotions Instrument 2023, FCA 2023/27) · COBS 4.12A.37G · 4.12A.41G

“should be provided in an appropriate language in addition to English”

Verbatim extract, read on 4 November 2026 from the source below. Everything else on this page is NorthPoint’s plain-English reading.

What it requires.

  • The FCA expects firms to take account of the latest Web Content Accessibility Guidelines (WCAG) when designing digital promotions, in particular how the risk warning is displayed.
  • Where intended or likely recipients are unlikely to understand English well, the risk warning or risk summary is provided in an appropriate language as well as English.

Who it applies to.

Firms designing digital financial promotions — and digital personalised risk warnings and risk summaries — for restricted mass market investments, including cryptoassets.

Common violations in marketing copy.

Violation pattern · low-contrast warning

Grey 9 px risk text on a gradient banner

Fails the contrast and legibility the WCAG reference points to.

Violation pattern · English-only warning

A Polish-language campaign carrying only the English warning

Recipients unlikely to understand English need the warning in their language too.

Non-compliant vs compliant.

Non-compliant · example written by NorthPoint

“A 6-second video ad with the warning on screen for one second in small grey text.”

Compliant · example written by NorthPoint

“The warning in body-size text with WCAG-level contrast, on screen for the whole ad, and in the campaign's language as well as English.”
