Oil prices held steady Tuesday as Iran conducted war games in the Strait of Hormuz, a trade chokepoint that is vital for international crude supplies.

U.S. crude

oil rose 53 cents, or 0.84%, to $63.42 per barrel by 8:45 a.m. ET. Global benchmark Brent

was down 29 cents, or 0.42%, to $68.36.

Traffic through the strait was suspended for several hours Tuesday as the Islamic Revolution Guard Corps (IRCG) held naval exercises, according to Iran’s semi-official Tasnim news agency.
