It cost a lot of money to suppress oil prices by shorting futures without any physical oil flowing. i.e. sell contract at lower price now then buy physical at whatever price on the physical market when its due.Bruh
This isn't just UAE, Saudi is behind this aren't they? They're using UAE to test the water?
Bailing out UAE is in a way the exact same thing: they either subsidize the petro dollar with treasury or they lose it, but they'll also lose it if they keep subsidizing without physical.
At end of the day you can't out-finance physical lack of energy.
