Saudi Arabia has refused to cut interest rates in lockstep with the US Federal Reserve for the first time, signalling that the oil-rich Gulf kingdom is preparing to break the dollar currency peg in a move that risks setting off a stampede out of the dollar across the Middle East.
This is big, because it means Middle East oil money now has a reason to flow from the US to Saudi Arabia. More over, as long as the riyal is pegged to the dollar, you can now make more money buying Saudi bonds then US bonds. This inflow of money is why breaking interest rate lockstep means that the riyal will have to revalue at some point.
