Oil prices jump as US votes: Markets on edge

US stock futures fell on Tuesday as oil prices climbed, reflecting investor concern that Washington and Tehran remain far apart on a peace deal. The uncertainty weighed on markets ahead of the US midterm elections. S&P 500 futures slipped 0.2%. Brent crude rose 1.7% to above $106 a barrel. Reuters reported that major obstacles to ending the conflict remain, despite signals from both capitals that they are open to a diplomatic solution. Nasdaq 100 futures were flat, suggesting a steadier start for technology stocks after the index entered a technical correction. A technical correction means a decline of at least 10% from a recent peak.
