The era of a strong, passive dollar designed to attract foreign capital is over. The US now actively manipulates the dollar's value to suit strategic needs, rewarding allies and punishing enemies. The currency has been drafted into foreign policy as a tool of statecraft, moving from a stable 'King' to an active 'General'.

The decline in the U.S. net foreign asset position is often attributed solely to trade deficits. However, a major driver was the appreciation of foreign investments in the U.S. equity market, which outperformed global markets and thus increased the value of U.S. liabilities to the world.

While a major sell-off in AI stocks would likely cause an initial "knee-jerk" strengthening of the US dollar due to risk aversion, the subsequent focus would shift to the US's twin deficits, leading to a multi-year dollar weakening trend once volatility subsides.

Banning US oil exports would reduce the global supply of dollars needed to purchase those commodities. This decline in demand for dollars could cause the currency to fall, creating unintended domestic inflation and risking destabilizing capital outflows from US assets.

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.

A government's repeated efforts to defend its currency paradoxically weaken it. Each intervention signals to the market that the country is in economic trouble, eroding investor confidence and creating a self-reinforcing downward spiral. The only sustainable defense is not intervention, but genuine, underlying economic growth and structural reform.

In a regime of fiscal dominance, where government spending dictates policy, the currency, not bond yields, becomes the primary release valve for economic pressure. While equities and yields may appear stable, the true cost of stimulus will be reflected in a devaluing dollar, a risk often overlooked by bond vigilantes.

The classic "stocks down, dollar up" correlation is weakening. A J.P. Morgan model shows that relative US equity underperformance (dollar-negative) is currently offsetting the effect of an outright global equity decline (dollar-positive). This dynamic leads to only modest moves in the dollar despite stock market stress.

The U.S. Dollar's value has been driven less by conventional factors like growth expectations and more by an unconventional "risk premium." This premium reflects market reactions to policy uncertainty, such as talk of FX intervention or tariffs. This has caused the dollar to weaken far more than interest rate differentials alone would suggest, creating a significant valuation gap.
