Oil prices dropped further on Thursday after US President Donald Trump and his Iranian counterpart signed off on a deal to end four months of war and reopen the Strait of Hormuz to tanker and cargo traffic.
Wall Street was cautiously in the green around a half hour into trading, with the Dow, the broader-based S&P 500 and the tech-heavy Nasdaq up just above 0.5 percent.
