Economic activity expanded across all 12 Federal Reserve districts in June, according to the central bank's Beige Book report, published on Wednesday.
The report said the pace of growth in these districts since the last Beige Book survey in May ranged from slight to moderate and most districts expected modest to moderate growth in the months ahead.
Consumer spending rose across the majority of regions thanks to gains in retail sales and tourism, although several areas reported softening in sales of motor vehicles.
Manufacturing and services activity continued to grow and construction activity expanded or was flat in most districts.
Labour markets tightened and wages increased at a modest to moderate pace, with companies surveyed reporting rising wage pressures among both low- and high-skilled positions.
Low level inflation, however, looked likely to cause the Fed further concerns, as "a few districts noted that price pressures had eased slightly". The majority reported prices rising modestly.
Earlier, chair Janet Yellen struck a more dovish tone than Fed-watchers have been used to in recent weeks when she said inflation remained an uncertainty.
Speaking in front of Congress, Yellen said: "Considerable uncertainty always attends the economic outlook. There is, for example, uncertainty about when, and how much, inflation will respond to tightening resource utilisation."
