American consumers borrowed less for a record eighth straight month in September amid rising unemployment and tight credit conditions. Economists worry the declines in borrowing will drag on the fledgling recovery.

The Federal Reserve said Friday that borrowing fell at an annual rate of $14.8 billion in September. That's the biggest decline since July and was larger than the $10 billion drop economists expected.

Americans are borrowing less as they try to repair cracked nest eggs and replenish rainy day funds in a dismal job market. Many are finding it hard to get credit as banks, hit by the worst financial crisis in decades, have tightened lending standards.

Borrowing by consumers for revolving credit, including credit cards, fell at an annual rate of 13.3 percent in September, the same as August. This category has declined for a record 12 straight months.

Borrowing for non-revolving loans, including auto loans, dropped at an annual rate of 3.7 percent in September after edging up 0.1 percent in August. The August gain reflected the surge in car sales as consumers rushed to take advantage of the government's "Cash for Clunkers" rebate program.

The $14.8 billion overall decline in borrowing left total consumer credit at $2.46 trillion in September. The 7.2 percent annual rate of decline followed a 4.8 percent drop in August. The Fed's report doesn't include mortgages or other loans secured by real estate.

While economists have worried for years about the low rate of U.S. savings, the concern is that consumers could derail the recovery if they begin socking away too much of their incomes. Consumer spending accounts for 70 percent of total economic activity.

The government reported last week that the overall economy grew at an annual rate of 3.5 percent in the July-September quarter, the first growth after a record four straight declines and the strongest signal yet that the recession has ended.
