U.S. Price Pressures Percolate With Surging Sales, Input Costs

The U.S. economy is starting to display pockets of price pressures, further stoking the debate among economists and market participants over the future path of inflation.

Among reports Wednesday, retail sales powered ahead with the strongest advance in seven months, topping all estimates and indicating hearty consumer demand at the start of the year.

Meanwhile, a measure of producer prices surged last month by the most in records dating back to 2009, while a private survey of homebuilders showed growing concern about soaring costs of building materials after a robust year for home sales.

While inflation gauges are expected to pick up steam this year, most notably in the second quarter, many economists -- including those at the Federal Reserve -- anticipate that annual price gains exceeding the central bank’s 2% target will prove temporary amid still-high unemployment.

Yet recent economic data and expectations of a potential $1.9 trillion in additional fiscal stimulus present upside risks to inflation expectations.
