SoH is not closed. GCC production/export capacity is not completely zero yet. Iran controls it though. If US doesn't agree to peace, then any food/water imports to GCC and oil exports getting a 10% Iran tax/toll is a better deal for everyone than not letting shipping go through. Gulf oil has hit $165/bbl today. A month ago, GCC was happy getting $65/bbl. They are happy at any number "net" in between, as are their Asian customers. Paying in Yuan is not a "showstopper" problem for any of them.
US language is rapidly de escalating, if you look for it.
