Google has moved to ban adverts that promote contracts for difference (CFD) products, binary options and financial spread betting from its platforms.
Google had been due to introduce the new regulations in June, but has opted to bring this forward.
The ban will also impact cryptocurrencies and related content, including initial coin offerings, cryptocurrency exchanges, wallets and trading advice.
Advertisers offering CFD products, rolling spot forex and financial spread betting will now be required to be certified by Google before they can advertise through its AdWords service.
Certification will only be available in certain countries and advertisers will need to be licensed by the relevant financial services authority in the regions they are targeting.
Advertisers will also be required to ensure their ads and landing pages comply with AdWords policies, as well as comply with the relevant legal requirements.
The move comes after social media network Facebook also recently introduced new rules to ban the advertisement of cryptocurrencies on its platforms.
