Brexit jitters send US stock futures down in early trade, pound reels

Brexit spills into global markets

U.S. stock futures opened to the downside in early trading Sunday, as investors grew increasingly restive in the wake of the U.K.'s decision to extricate itself from the European Union.

Risk aversion also sent the reeling to near $1.34, within view of its lowest in 30 years around $1.32. Early Sunday, Goldman Sachs issued a research note predicting that Britain could enter a recession by next year, and the bank sharply downgraded global growth expectations.

Dow futures fell, with the implied opening signaling a 150-point drop, while S&P 500 futures pointed to a 21-point decline and NASDAQ futures indicated a 43-point drop. Gold futures rose, in a reflection of sustained demand for safe-haven assets.

Despite a rough day Friday, in which the Dow tumbled 610 points and each of the major averages fell at least 3 percent, the mood heading into Monday was downbeat but not panicky.

The pound's loss against the dollar amounted to about 1.3 percent.while the euro was off 0.75 percent. U.K. government bond yields were mixed with the 10-year edging higher just a bit.

Asian stocks fell at the open, with Japan's Nikkei off 1.5 percent. Futures for the U.K.'s FTSE indicated a drop of 3 percent at the open.
