The danger to the U.S. dollar is not a dramatic replacement by the Euro or RMB, but a slow erosion of its primacy. This is visible in central banks increasing gold reserves, greater hedging activity, and China’s de-dollarization campaign. This gradual shift ultimately raises borrowing costs for the US government and American consumers.

America's ability to deficit spend relies on the world's appetite for US debt, which allows it to export inflation. If countries dump this debt, the US can no longer "tax the world," triggering immediate domestic austerity and creating a global power vacuum likely to be filled by China.

The U.S. economy's ability to consume more than it produces is not due to superior productivity but to the dollar's role as the world's reserve currency. This allows the U.S. to export paper currency and import real goods, a privilege that is now at risk as the world diversifies away from the dollar.

The "yield smile" theory posits that bond yields rise in both very strong and very weak economies. In good times, inflation pushes yields up. In bad times, worsening deficits and increased bond supply cause a sell-off, also pushing yields up, trapping policymakers.

The U.S. dollar's decline is forecast to persist into H1 2026, driven by more than just policy shifts. As U.S. interest rate advantages narrow relative to the rest of the world, hedging costs for foreign investors decrease. This provides a greater incentive for investors to hedge their currency exposure, leading to increased dollar selling.

The US dollar reached its peak global dominance in the early 2000s. The world is now gradually shifting to a system where multiple currencies (like the euro and yuan) and neutral assets (like gold) share the role of reserve currency, marking a return to a more historically normal state.

The surge in gold's value isn't just about uncertainty; it's a direct signal that foreign central banks and major investors are losing confidence in U.S. treasuries as a safe asset. This shift threatens the global dominance of the U.S. dollar.

Despite conditions that typically strengthen the US dollar (rising oil prices, war), its recent performance has been weak. This suggests a structural erosion of its safe-haven status and global dominance, potentially due to declining use in global trade, which has long-term inflationary implications for the US.

For decades, a tacit global agreement existed: the U.S. buys the world's goods and provides security, and in return, the world finances U.S. debt by buying Treasuries. As U.S. policy shifts towards protectionism and reduced global policing, other nations may no longer feel obligated to fund U.S. deficits, pushing borrowing costs higher.
