The S&P 500 and Nasdaq ended lower, while the Dow closed up slightly. All three indexes registered declines for the week. Rising coronavirus deaths are causing fresh business restrictions in many U.S. states and increasing layoffs, making investors anxious to hear whether more fiscal relief is coming.

The dollar rose with safe-haven buying as investors’ risk appetite soured. The dollar index was last up 0.2%. Sterling slipped as bets on further volatility in the currency grew over the increasing likelihood of a disorderly Brexit. Sterling was last trading at $1.3222, down 0.53% on the day. Britain is likely to complete its journey out of the European Union in three weeks without a trade deal, British Prime Minister Boris Johnson and European Commission chief Ursula von der Leyen said on Friday.
