European football's governing body are investigating allegations made in German publication Der Spiegel last month that City's Abu Dhabi owners inflated sponsorship agreements in order to comply with FFP requirements.
In response, Premier League champions City said information had been "hacked" and that they were victims of an "organised and clear" attempt to damage the club's reputation.
Punishment for clubs found guilty of breaking the rules could extend to being excluded from the Champions League.
Guardiola, appointed with the task of trying to win Europe's biggest club prize, said he was calm about the situation.
"We will not be banned, no. That's what I think because I trust in my chairman (Khaldoon al-Mubarak), with my CEO (Ferran Soriano), what they have explained to me. I trust in them," the Spaniard was quoted as saying by British media.
"If it happens, because UEFA decide that, we will accept it and move forward."
Der Spiegel's report, based on documents received by the whistle blower platform Football Leaks and reviewed by Reuters, in partnership with European Investigative Collaborations, a network of international media, alleged that some of City's Abu Dhabi sponsorships were three times more lucrative than independent experts deemed they were worth.
City said the claims were "erroneous conclusions and assertions." (Reporting by Martyn Herman; Editing by Peter Rutherford )
