On Monday, we brought you "Saudi Default, Devaluation Odds Spike As Mid-East Careens Into Chaos," in which we outlined the jump in riyal forwards and widening of CDS spreads that Riyadh witnessed in the aftermath of the kingdom's move to cut diplomatic ties with Iran.

In short: the market is getting worried that Riyadh is about to careen into crisis. In the face of slumping crude, the Saudis are staring down double digit budget deficits and the prospect of having to once again tap debt markets in order to offset the SAMA burn and keep the kingdom from having to implement further subsidy cuts.

The open hostilities with Iran all but guarantee the war in Yemen will escalate (just today for instance, Tehran accused the Saudis of bombing the Iranian embassy in Sana'a) and that entails a further drain on the kingdom's finances as the monarchy will be forced to fund a prolonged and intractable struggle with the Houthis.
