"We are seeing some evidence that the weakness in the first-quarter has spilled over to this quarter, but I'm not concerned that US consumer spending for the year is at risk," Jeremy Zirin, head of investment strategy at UBS Wealth Management in New York, told Reuters.
John Ryding, chief economist at RDQ Economics in New York, agreed.
"We remain puzzled by the softness in retail sales given the gains in employment, real incomes from lower energy prices, and wealth, but we continue to look for consumer spending to pick up this year," Ryding told Reuters.
Meanwhile, the pressure on rates continued in the bond market, pushing yields on the 10-year US benchmark bond to the highest level in nine months. Higher yields make fixed-income securities more appealing to investors.

A report showed the euro-zone economy expanded 0.4 per cent in the first quarter, its best clip in nearly two years. Still, the pace of growth in Germany, the region's engine economy, disappointed as it slowed to 0.3 per cent, down from 0.7 per cent in the previous period.
The euro benefited.
"On the European side, we have had some good numbers, and on the other side, people have been disappointed in the performance of US data, and that is weighing on the [US] dollar and allowing the euro to trade higher," Sonja Marten, a currency strategist at DZ Bank in Frankfurt, told Bloomberg.
