A Federal Reserve interest rate cut in September, the first this year, followed perhaps by another before year-end remains the base forecast for most economists polled by Reuters amid rising concerns about the health of the world's biggest economy.

Inflation held steady in July and ran slightly cooler than expected, increasing the odds of a Federal Reserve rate cut next month.
