"We should stop the championship this year and start again next year, hopefully, because I can't see it's going to be possible to get the right amount of races in that count for a championship," the 89-year-old told BBC Radio.
"There's got to be eight from memory, and I can't see them getting that in. It's a difficult situation."
A minimum of eight races are needed for a championship season to be deemed valid and there are only 14 races left now.
The season is a special one for current champion Lewis Hamilton, who stands a chance at matching Michael Schumacher's record of seven championship wins. Ecclestone said that should the season go through and Hamilton wins a truncated championship, the achievement won't be belittled.
"I don't think it will make a lot of difference to Lewis. He would win whatever the race number, whether it be eight, 16 or 20," said Ecclestone.
"If it's a world championship and he wins, it would go on his record and say he has won a world championship. The terrible thing is he would win all eight races. It wouldn't be a super championship."
