US economic growth in the fourth quarter has been revised down to a 0.5% annualized rate, according to the Commerce Department's Bureau of Economic Analysis. This is due to downgrades to business investment, including inventory accumulation, and decreased consumer spending. Corporate profits also increased, rising at a rate of $246.9 billion. The shutdown of the government was a key driver of the slowdown. Despite this, the U.S.-Israeli war on Iran is affecting the economy.
