France's consumer confidence index fell by 5 points to 80 in October, hitting a 13-year low and falling short of the median forecast of 85, due to multiple shocks including a bond market sell-off and protests escalating into riots, the French statistics agency Insee said on Tuesday. Respondents expressed increased concerns about their financial situation, living standards, and unemployment. The indicator has remained below its long-term average of 100 for five consecutive years.
