Brent was $105.19 in Asia. That is not a New York close.

NEW YORK — Investors were weighing a possible shift in control of Congress as Election Day arrived, Reuters reported, and whether a strong Democratic showing would add volatility, particularly in the trade that has driven markets. Scott Chronert, U.S. equity strategist at Citigroup, wrote: “While probabilities increasingly favor a Blue sweep, several tightly contested Senate races leave open some possibility of Republican control of the Senate or, conversely, a greater than expected Democratic foothold in the Senate.” He added: “Equity market reaction is likely positive in the former case and negative in the latter.” UBS Global Wealth Management assigned a 50 percent probability of a Democratic sweep, 40 percent to Democrats taking the House while Republicans keep the Senate, and 10 percent to Republicans holding both. Those are the strategists’ figures. They are not a vote count.

In a separate Reuters note, Brent crude was 0.4 percent higher at $105.19 in Asian trading. Reuters said crude had fallen about 7 percent on Monday as investors weighed reports of mediation, before the strikes on Qeshm. This $105.19 is Asia’s print. It is not a New York close, and it is not Friday’s $117.64. The strikes themselves are in the war note. They are not retold here as a new toll.

While probabilities increasingly favor a Blue sweep, several tightly contested Senate races leave open some possibility of Republican control of the Senate or, conversely, a greater than expected Democratic foothold in the Senate.
