It is the lowest since the board began tracking consumer sentiment in 1967.

"This news does not bode well for retailers who are already bracing for what is shaping up to be a very challenging holiday season."
The fall in consumer confidence followed three consecutive months of modest gains.
But Ms Franco said: "In assessing current conditions, consumers rated the labour market and business conditions much less favourably, suggesting that the fourth quarter is off to a weaker start than the third quarter.
"Looking ahead, consumers are extremely pessimistic and a significantly larger proportion than last month foresees business and labour market conditions worsening."
