AI Investment And The U.S. Economy – Analysis

Eurasia Review | Lida R. Weinstock, Marc Labonte

Artificial intelligence infrastructure spending fueled U.S. gross domestic product growth throughout 2025 and early 2026 through massive debt-financed data center and semiconductor expansion. Federal Reserve estimates indicate global trade in AI hardware grew 65 percent in the first half of 2025, offsetting raw domestic output gains through increased import volumes.

This rapid capital allocation puts upward pressure on long-term interest rates while widening the U.S. current account deficit. Goldman Sachs projects chip and electricity demand will increase peak inflation by 0.5 percentage points. Debt risks are compounding. In response, the 119th Congress considered the Ratepayer Protection Act, H.R. 9340, to insulate consumers from utility price spikes. A Bank for International Settlements study estimates current capital allocation exceeds efficient levels by 1.5 times. Rapid capital depreciation and circular financing heighten systemic financial risks. Still, Goldman Sachs forecasts AI investment will expand to 2.8 percent of GDP by 2028.

Comment

Debt-heavy commercial financing for data infrastructure directly competes with federal sovereign debt issuance and defence industrial retooling for private capital. As corporate bond yields rise to absorb massive technology issuance, defence prime contractors such as General Dynamics face higher borrowing costs for long-term shipyard and munitions capacity expansion. This credit tightening reduces the private capital available for facilities funded under Title III of the Defence Production Act.

Higher corporate debt yields subsequently constrain the naval shipbuilding pipeline, where long lead-time platforms rely on multi-year financing structures. Elevated borrowing costs expand the unit financing costs for Columbia-class ballistic missile submarines, forcing trade-offs between hull procurement rates and fleet modernisation budgets. Consequently, high private yield benchmarks reduce the inflation-adjusted purchasing power of the U.S. Navy's shipbuilding account without a formal congressional budget reduction.

Strategic Question for Discussion

If elevated corporate borrowing rates persist, which factor will constrain U.S. defence capital projects more severely — rising yield margins for prime contractors like General Dynamics or reduced purchasing power in Title III Defence Production Act grants?

The available evidence points toward yield margin pressures on defence prime contractors as the primary friction point. Direct federal grants through Title III of the Defence Production Act remain insulated by congressional appropriations, whereas private debt financing for capital-intensive facilities at shipyards directly absorbs rising market rates. My assessment is that this interest rate wedge will disproportionately slow multi-year yard expansions that rely on corporate bond issuance rather than direct Pentagon subsidies.
