Wholesale prices advanced 0.4% in June, according to the U.S. Labor Department, more than many analysts were expecting.

Core prices, which exclude food and energy, increased 0.3% in June, the biggest hike since October.

“From the Federal Reserve's perspective, stronger prices will help bolster the argument for a near-term [interest] rate increase, however, there is still a long way to go before we can talk about inflationary concerns,” said Lindsey Piegza, chief economist at Stifel Fixed Income.
The Federal Reserve has been looking to push short-term interest rates higher, which have been near zero since late 2008, but in the past has indicated the overall U.S. economy needs to show signs of steady growth, including having inflation of 2% annually. This has yet to happen, while there was negative overall economic growth in the first quarter of the year.
