The world-famous broadcaster runs a host of national, international and regional radio stations, but it doesn't have immediate plans to switch exclusively to digital because "audiences want choice".
Speaking at a conference in Vienna, BBC director of radio and music Bob Shennan said: "We need to do more in the UK before we consider a switchover and for that to be genuinely led by the audience.
"We are fully committed to digital and we believe we should review the landscape again in a few years' time."
Later this year, the UK government will undertake a review of FM and DAB.
Shennan thinks it would be "premature" to make the switchover, even though the UK listeners stand on the cusp of becoming predominantly digital.
He explained: "Great progress has been made but switchover now would be premature. For now we believe audiences are best served by a mixed economy.
"Radio is better served by a mixed economy."
The FM spectrum is overcrowded, which is one of the reasons why broadcasters are increasingly attracted to the idea of turning to DAB radio.
On the flipside, the platform can still be patchy, while lots of motor vehicles are still unable to pick up the service.
