NEWS: With the Iran deal signed, oil futures fell to their lowest since the conflict began.

Back in action: The US has agreed to remove its naval blockade from the Strait of Hormuz and drop sanctions on Iran oil and petroleum exports. Now, ships appear to be trickling out of the Persian Gulf again (and turning on tracking devices after months of no signal).

The market reacts: Yesterday, Brent futures reached their lowest price since the conflict began, and WTI hit its lowest since early March.
