🎥IRAN WAR PRIMER
Six days on from the start of this war, what have we learnt about the economic consequences?
Here's our latest primer, covering:
1. Why gas prices are up so much more than oil
2. The ticking timebomb facing Gulf oil producers
3. It's not just oil/gas - we need to talk about helium & sulphuric acid!
4. What does this mean for the 21st century economic model for Gulf states?
All that and much more in 10 mins. Longer than usual. But a lot to cover in this one 👇
