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.

Global demand for dollars as the reserve currency forces the U.S. to run persistent trade deficits to supply them. This strengthens the dollar and boosts import power but hollows out the domestic industrial base. A future decline in dollar demand would create a painful economic transition.
The post-1980s neoliberal consensus of small government and free trade is being replaced by a mercantilist approach. Governments, particularly the U.S., now actively intervene to protect domestic industries and secure geopolitical strength, treating trade as a zero-sum game. This represents a fundamental economic shift for investors.
While U.S. fiscal deficits remain high, new tariffs are reducing the trade deficit. This means fewer U.S. dollars are flowing abroad to foreign entities who would typically recycle them into buying U.S. assets like treasuries. This dynamic creates a dollar liquidity crunch, strengthening the dollar.
The US is not facing a single issue but a convergence of multiple stressors. Unsustainable fiscal policy, fragile funding markets, geopolitical shifts, energy production issues, and leveraged financial players create a highly volatile environment where one failure could trigger a cascade.
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.
A simple framework explains the structural shift to higher interest rates. Retiring Boomers spend savings (Demographics), governments borrow more (Debt), global capital flows fracture (Deglobalization), AI requires huge investment (Data Centers), and geopolitical tensions increase military spending (Defense). These factors collectively increase borrowing costs.
After WWII, the U.S. used its naval dominance to guarantee global trade. In exchange for writing its allies' security policies, it allowed open access to its market. This economic "unfairness" was the strategic cost of building a global coalition against the Soviet Union, effectively bribing nations into an alliance.
The fall of the dollar as the world's reserve currency isn't an abstract economic event. It would have immediate, tangible consequences for citizens, including skyrocketing prices for imported goods like energy and medicine, a sharp drop in living standards, and an exodus of talent and capital to more stable regions.
When countries run large, structural government deficits, their policy options become limited. Historically, this state of 'fiscal dominance' leads to the implementation of capital controls and other financial frictions to prevent capital flight and manage the currency, increasing risks for investors.
As foreign nations sell off US debt, promoting stablecoins backed by US Treasuries creates a new, decentralized global market of buyers. This shrewdly helps the US manage its debt and extend the life of its reserve currency status for decades.
