Oil benchmarks Brent and WTI fell by about 5% in trading on June 15, with WTI briefly falling below $80 per barrel for the first time since March, after the announcement of the U.S.-Iran memorandum of understanding that extends their ceasefire by 60 days and removes restrictions on shipping through the Strait of Hormuz. While U.S. officials have said Iran cannot charge a toll for ships passing through the strait, Iran's foreign ministry said it will charge ships a "maritime service fee."
