Following the end of a horrible week for petroleum importers (not to mention shale producers) despite WTI briefly dipping under $40 (wasn’t this supposed to be great news for the US economy?) we have the start of a just as ugly week for the Persian Gulf oil exporters, whose Sunday market open can be described as a continuation of last week’s broad risk carnage, and where Saudi Arabia, until recently the region’s best performing market, is now down 10% for the year and down 30% compared to 12 months ago.
