Macro environment 'challenging' for Mondelez: CEO

Mondelez: Pressure from currencies & input costs

Despite offering products that sell so well around the world, Mondelez International has been hit hard by several external factors recently, the company's CEO said.

"Input costs have been exceptionally volatile. We're with the largest cocoa producer in the world, and cocoa has been an exceptionally volatile input over the last 12 months," Irene Rosenfeld told CNBC's "Squawk on the Street" on Tuesday.

Another factor affecting Mondelez is the recent volatility in world currencies, Rosenfeld said. Eighty percent of the company's revenues come from outside the U.S.

Nevertheless, the company remains in good shape because of its large snacks portfolio, Rosenfeld said. "[Snacks] are growing around the world even when markets slow down a little bit," she said. "The good news is ... we have an advantage set of snacks within our portfolio."

Mondelez's snacks portfolio includes Oreo cookies, Cadbury chocolate and Ritz Crackers.
