Aaron Brown argues the "petrodollar loop" is under strain as the U.S. is seen as an unreliable security partner, and foreign central banks have been learning to "live without the dollar," a process accelerated by the Iran war. The foundational deal where the U.S. provides security for oil shipments in exchange for dollar recycling into Treasuries is fraying. This suggests a long-term, structural decline in dollar demand for reserve assets, despite short-term strength. The direction is WATCH for a long-term strategic weakening, as the geopolitical shift incentivizes diversification away from dollar dependency, though the process will be slow. A swift resolution to the Iran conflict that re-establishes U.S. security guarantees and restores confidence in the existing financial order.
