"$90 a barrel is tolerable for the global economy," says Stewart Glickman when referring to crude oil prices, though he believes consistency above $100 will create substantial pressure. He adds that even current prices aren't sustainable long-term. Stewart points to attacks on Saudi oil infrastructure as a significant headwinds to restoring previous trading volume through the Strait of Hormuz. He makes the case that heightened crude prices will opened a trap door for a recession.
