The decision by BMW to pull out of the Formula One competition backs up the governing body's case for a budget cap, says FIA president Max Mosely.
BMW Sauber has confirmed it will pull out at the end of what has been a disastrous season for the German car manufacturer.
BMW drivers Nick Heidfeld and Robert Kubica are 13th and 15th respectively, while the BMW Sauber team is eighth with just eight points.
But Mr Mosely believes the decision is prompted more by the financial crisis than BMW's results.
He is sure there will be significant reductions in spending in Formula One, though no budget cap - a battle he lost with teams participating in the competition.
Meanwhile, Michael Schumacher has announced his comeback.
The German F1 legend, who will fill in for injured Felipe Massa until the Brazilian is fit enough to return, retired in 2006 as a seven-time drivers' world champion.
