Formula One needs an urgent discussion of its budget cap as teams are squeezed by inflation, high energy costs and rising interest rates, Red Bull boss Christian Horner said on Friday.
The sport's current cap is $140 million a year per team, with some items such as driver salaries not included, down from $145 million in 2021. It is due to drop to $135 million next season.
Horner told reporters during pre-season testing in Bahrain that jobs could be at risk as tightly-controlled budgets were eroded.
Most of the teams are based in Britain, where inflation is set to reach its highest level since the early 1980s and energy prices have surged.
