WASHINGTON, May 14 (UPI) -- U.S. wholesale prices rose for the second month in a row, suggesting that pricing pressures are building despite an extended period of low inflation.
The producer price index rose by a seasonally adjusted 0.6 percent for the month of April, up from 0.5 percent in March, according to the Labor Department. Economists surveyed by MarketWatch estimated a 0.2 percent increase.
