America's Economic Arsenal: Why Trade Policy Is the New Deterrent

The Old Firewall Between Trade and Defense

For most of the post-Cold War era, American strategists treated the economy as something the Treasury managed and the Pacific as something the Pentagon patrolled, but that firewall never made sense, and in 2026 it is dangerous because the tools of national power now sit on the same ledger, and ignoring that fact is a luxury no strategist can afford.

Consider the numbers. The Census Bureau reported that United States goods trade with China reached $582.4 billion in 2024, while the goods trade deficit with Beijing hit $295.4 billion. Those are not abstract figures on a spreadsheet. They represent leverage. Every dollar of dependence is a pressure point the Chinese Communist Party can exploit in a crisis over Taiwan, the South China Sea, or rare-earth supply.

The Department of Defense understands this better than many in Congress. The Pentagon's fiscal year 2026 budget request exceeds $850 billion, yet a significant portion of that spending is devoted to mitigating risks created by civilian supply chains. Missiles need semiconductors. Ships need steel. Satellites need rare earths. When those inputs flow from a strategic competitor, defense procurement becomes a hostage arrangement.

Conservatives have traditionally favored free markets, and rightly so. But free markets require reciprocity and security. Beijing does not believe in either. The Commerce Department's Bureau of Industry and Security has spent the last several years tightening export controls on advanced semiconductors, chipmaking equipment, and artificial-intelligence hardware bound for China. Those controls are economic policy. They are also defense policy. The line between the two has vanished.

China's Economic Leverage Is a Strategic Weapon

Beijing's economic toolkit goes far beyond tariffs and trade barriers, because its most potent weapon is structural dominance over the raw materials and industrial inputs that power modern military technology, including the rare-earth refining capacity that the United States Geological Survey estimates China controls at roughly 87 percent globally.

That dominance gives Beijing the ability to throttle production during a conflict or embargo, turning a peacetime market into a wartime chokepoint. The Treasury Department publishes monthly data on foreign holdings of United States debt. As of early 2026, China holds roughly $765 billion in Treasury securities. That is down from the peak of over $1.3 trillion in 2013, but it remains large enough to matter. Beijing has demonstrated a willingness to reduce those holdings during periods of tension, and even gradual sales can raise borrowing costs for Washington at the worst possible moment.

The Congressional Budget Office has warned that rising interest costs will crowd out discretionary spending over the next decade. In 2024, net interest on the federal debt already reached $892 billion, exceeding defense outlays of $841 billion. Add a foreign creditor using debt sales as leverage, and the problem becomes strategic as well as fiscal. Dependence on Chinese financing limits American freedom of action in the Pacific.

Semiconductors tell the same story. The CHIPS and Science Act allocated $52.7 billion in subsidies to restore advanced chip manufacturing in the United States. That legislation was framed as industrial policy, but its purpose is inseparable from defense. Advanced chips power everything from guided munitions to signals intelligence. Allowing those supply chains to concentrate in Taiwan and South Korea, within range of Chinese missile threats, is a risk no serious strategist can accept.

What Washington Should Do Differently

The first step for Washington is to stop pretending that trade policy and defense policy are different departments, since they are not, and every tariff, export license, and procurement rule should be judged first by its effect on national security rather than quarterly earnings. The second step is to rebuild the industrial base that makes independent action possible.

That means expanding domestic mining and refining of critical minerals under reasonable environmental rules, not the regulatory regime that currently keeps American deposits idle while China controls global supply. It means completing the CHIPS Act buildout on schedule and demanding accountability from recipients who take federal money. It means streamlining defense procurement so new technologies reach the field before they become obsolete.

Allies matter too. Japan, Australia, South Korea, and the Philippines share an interest in resilient supply chains. The United States should lead a coalition that diversifies rare-earth refining, semiconductor packaging, and maritime logistics away from China. Economic integration among free nations is a force multiplier. Economic dependence on Beijing is a liability.

Finally, fiscal discipline is itself a strategic asset. A nation that borrows heavily from its chief competitor cannot afford to deter it. Reducing the deficit, controlling entitlement growth, and restoring federal balance sheets are conservative priorities that happen to be foreign-policy necessities. The Pacific balance of power will be shaped as much by bond markets as by battleship hulls.

The old argument pitted free traders against national-security hawks. That debate is over. The only question now is whether Washington can build an economic arsenal to match its military one. If it cannot, the weapons will be there, but the supply lines will not.
