The German side are currently still paying off debt for the Allianz Arena, the state-of-the-art stadium which reportedly cost the club €340 million to complete back in 2005.
Hoeness believes that the club will be able to maximise their financial potential when they finish paying off the debt and be able to compete with noveau-riche clubs like Manchester City.
He told Bild: "We will be free of stadium debt in six or seven years, and then we will be the richest club in the world, based on equity.
"A club like Manchester City would be richer, but only because of their owner. We are independent and economically the healthiest team in the world."
The Bayern president then praised the work of Germany coach Joachim Low and named Germany as favourites to dethrone Spain as European champions.
He added: "You have to take your hat off to Joachim Low and his team. The first half against Holland [3-0 win for Germany in November] was football from another planet.
"Based on this game, I am convinced that we will be European champions. The national team has what it takes to beat anyone."
Bayern Munich are currently leading the Bundesliga table by three points into the winter break and will resume their domestic campaign on 20 January against third-placed Borussia Monchengladbach.
