US stock markets sink again following Brexit vote

Major markets see biggest two-day fall in 10 months, but Moody's analyst says referendum result may not cause real damage to US economy

US stock markets were rocked again on Monday by the aftershocks of the UK's referendum decision to quit the European Union.

Since the results became known on Thursday, the major US markets have suffered their biggest two-day fall in 10 months. Monday's dips came as the pound collapsed to its lowest point since 1985 and the UK lost its triple-A credit rating.
