Treasuries climbed and the dollar weakened after worse-than-forecast US payrolls bolstered the case for keeping interest rates lower for longer. US stock futures tumbled amid concern economic growth softened in the first quarter, Bloomberg said. The yield on 10-year Treasuries dropped 7 basis points to 1.84 percent at 12 p.m. in New York, reaching a two-month low. Standard & Poor’s 500 Index futures lost 1 percent and the Bloomberg Dollar Spot Index slid 0.8 percent. The MSCI Emerging Markets Index topped 1,000 for the first time this year in its biggest weekly gain since 2012. Markets across Asia, the U.S. and Europe were closed for holidays Friday.
