Any countries in continued breach of the rules are at risk of hefty EU fines.
Claus Vistesen, an economist at Pantheon Macroeconomics, said bond investors are worried that the French government will struggle to meet EU demands to cut borrowing amid stiff parliamentary opposition.
“Markets have started to sniff out that there is a risk of a big stalemate when nothing gets done in the budget,” he said.
“You can have a prime minister in place, but if there is no big majority behind political decisions, something like the budget is going to be left to drift.”
Mr Barnier last week warned that France is borrowing far too heavily.
“Our country is in a very grave situation – €3 trillion [£2.5 trillion] of debt and €50bn in interest to pay a year,” the Prime Minister said in a TV interview.
“A lot of our debt is on international markets – we must preserve France’s credibility.”
France’s national debt predicted to rise from 110.6pc of GDP to 113.8pc over the next 12 months, fuelling fears across financial markets.
