No there were 2 money in the bank matches. Each match was for a specific title. Zigglers briefcase was for the World Title.
Cena peviously had the brief case for the WWE Title. He cashed it in against CM Punk and lost. He however was a tool and with his whole Hustle, Loyalty, Respect schtick told Punk he was gonna cash it in a week ahead of time so he got zero advantage from it.
