The cost of the US-Iran conflict continues to escalate, estimated at between 800 million to @E1@ 2 billion per day, which exacerbates America's fiscal deficit and increasingly underscores the urgency of establishing a BRICS currency unit to challenge dollar dominance. Market reactions have reinforced this trend, with 30-year US Treasury yields approaching 4.90%, as investors have priced in war-induced inflation and higher debt issuance. Meanwhile, the de-dollarization infrastructure of BRICS nations is operational, including the mBridge platform, which has processed over @E2@ 55 billion in transactions, and bilateral trade settlements conducted in local currencies. The proposed BRICS currency unit, backed by gold reserves at 40%, poses an increasingly severe structural threat to the dollar's status as the global reserve currency amid sustained US fiscal pressures.
