U.S. economy is coping with high inflation

Consumer spending snapped back in August after a brief lull, adding to mounting evidence of an acceleration in the U.S. economy despite a series of strains.

Personal spending increased surged 0.9% last month, the government said, after barely any increase in July. Americans bought more new cars and increased spending at restaurants and clothing stores.

Yet the necessities of life - gas, health care, auto repair - were also more expensive.

Incomes also rose 0.3% in the month to keep up with inflation, if just barely.

Key details: New car sales drove much of the increase in spending last month. People buy more big-ticket items like cars when they have confidence in the economy or security in their own jobs.

On the downside, spending also got a boost from an increase in gas prices after the U.S. and Iran resumed hostilities.

The savings rate fell to 4.1% from 4.6% in the prior month and is on the lower side historically. Households have had to dip into savings more to offset the high rate of inflation.

Consumer spending is the main engine of the U.S. economy. Spending in the spring grew at a surprisingly strong pace and it looks like the third quarter will follow suit.

Big picture: The economy is still growing steadily after six years of expansion - even stubborn inflation hasn't been able to slow it down much.

Yet a series of shocks - tariffs, war, high oil prices, rising interest rates - have kept the economy from performing even better.

Market reaction: The Dow Jones Industrial Average DJIA and S&P 500 SPX were set to rise in Wednesday trading.
