The United States’ conflict with Iran has triggered a shock to the global trading framework. Market participants see the war as a catalyst that could permanently reshape the dollar’s dominance. For the first time in decades, gold reserves have overtaken central bank dollar assets when both are measured on a valuation‑adjusted basis, signaling a rare shift in reserve preferences.

Investors have already responded by reallocating portfolios toward tangible stores of value, driving up bullion prices and pressuring sovereign wealth funds to reconsider their dollar‑heavy allocations. Analysts argue that the war’s impact on oil shipments and sanctions has amplified uncertainty, making alternative assets more attractive. The shift could erode the dollar’s low‑cost financing edge for emerging markets reliant on cheap credit.

Central banks now face a strategic dilemma: continue to rely on a currency whose geopolitical risk profile has risen, or diversify into precious metals that have just surpassed dollar holdings. With U.S. war with Iran altering risk calculations, policymakers may need to adjust reserve management rules to safeguard liquidity. The emerging hierarchy suggests a more fragmented reserve system is already taking shape.
