The US is signaling a major shift from its long-standing 'King Dollar' policy. By being willing to devalue the dollar, it can strategically intervene in currency markets to bolster allies like Japan while simultaneously hurting economic adversaries like China by making US manufacturing more competitive.

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.
Unlike the past, where economics dictated a strong yen despite loose policy, markets are now driven by politics. The Japanese government is allowing the yen to devalue to manage its debt, even as interest rates rise. This weakens the yen, strengthens the dollar, and could fuel a US equity boom via carry trades.
Despite official statements against rapid currency depreciation in Japan and Korea, policymakers likely view a weaker currency as a beneficial stimulus. With negative output gaps and competition from China, the goal is not to reverse the trend but to manage its pace to avoid market disorder and US Treasury scrutiny.
Modern global conflict is primarily economic, not kinetic. Nations now engage in strategic warfare through currency debasement, asset seizures, and manipulating capital flows. The objective is to inflict maximum financial damage on adversaries, making economic policy a primary weapon of war.
The US freezing Russian assets and cutting SWIFT access during the Ukraine war demonstrated the risks of relying on the dollar. This prompted countries like China to accelerate their diversification into gold, viewing it as a geopolitically neutral asset to reduce their vulnerability to US foreign policy and sanctions.
A weakening dollar reduces the credit risk for dollar-borrowers, which encourages more dollar-denominated lending. This credit is the lifeblood of intricate global supply chains. As a result, exports of sophisticated goods, like semiconductors, can thrive even during periods of dollar weakness.
The yen is nearing 160 against the dollar, a key level that has historically triggered intervention. A decisive break could lead to a 'dollar wrecking ball' scenario, causing a cascade of volatility across global currency, bond, and equity markets. This creates a high-stakes 'widowmaker trade' environment.
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.
Each time the U.S. uses financial sanctions, it demonstrates the risks of relying on the dollar system. This incentivizes adversaries like Russia and China to accelerate the development of parallel financial infrastructure, weakening the dollar's long-term network effect and dominance.
The aggressive, go-it-alone tactics of the 'America First' doctrine alienate both allies and adversaries. This pushes them to build alternative payment systems and trade alliances, speeding up the very de-dollarization and decline in U.S. influence that the strategy aims to prevent.
