Americans borrowed less for a 10th consecutive month in November with total credit and borrowing on credit cards falling by the largest amounts on records going back nearly seven decades.

The dramatic declines raised new worries about whether consumers will cut back further on spending, making it harder for the economy to mount a sustained rebound.

The Federal Reserve said Friday that total borrowing dropped by $17.5 billion in November, a much bigger decline than the $5 billion decrease economists had expected.
