President Donald Trump’s recent order to pull 5,000 U.S. military personnel out of Germany will trigger direct, long-lasting economic damage in the host regions, according to a comprehensive joint study published on Wednesday.
The empirical research, conducted by the ZEW – Leibniz Centre for European Economic Research and the University of Cologne, warns that the drawdown will decimate thousands of regional civilian jobs and destabilize municipal public finances.
The 0.53 Structural Multiplier: How Bases Prop Up German Regions
The study, co-authored by economists Jakob Schmidhäuser (ZEW) and Johannes Kochems (University of Cologne), established a devastating structural formula for local economies: every single withdrawn U.S. soldier costs the host region 0.53 of a local full-time civilian job.

To model the upcoming drawdown, researchers meticulously analyzed empirical data from the historic post-Cold War era in the 1990s, when roughly 200,000 American troops were repatriated from Germany. The historic data reveals that regional economic shockwaves extend far beyond the immediate parameter fences of shuttered military bases.
Severe Municipal Budget Crises and Tax Hikes
The economic contraction will rapidly bleed into local government balance sheets. Historically, when U.S. forces pulled out of German communities, neighboring municipalities suffered an immediate 9% drop in total public revenues.
To balance their budgets, local German authorities have historically been forced into severe economic consolidation measures:
- Public Spending Cuts: Slash municipal infrastructure programs, public services, and community projects.
- Aggressive Tax Multipliers: Artificially spike local property and business taxes by an average of 4.4% to compensate for the missing American capital.
- Long-Term Deficits: Even after desperate fiscal maneuvering, municipal revenue deficits permanently stagnated at 3% below baseline levels over the long term.
Co-author Johannes Kochems on the Fiscal Strain: “Municipalities have historically responded to the sudden loss of purchasing power and tax base by squeezing the remaining civilian population. They raise business and property tax multipliers simply to stay afloat, creating an unfavorable economic environment for subsequent regional investment.”
The Persistent 15-Year Scar on the German Workforce
Perhaps the most alarming finding of the ZEW report is the permanent economic scarring inflicted on displaced local workers. The data proves that individuals laid off due to U.S. military base contractions face immense hurdles adapting to the broader civilian labor market.

The report highlights that the long-term negative impact on labor outcomes is most severe for women, older workers, and those residing in structurally weak regional economies with fewer alternative employment sectors.
Geopolitical Realignment and the Toll on the Ground
The timing of the study is highly relevant, coming just weeks after the Pentagon formalized Trump’s directive to cut active-duty personnel in Germany from 36,000 down to roughly 31,000.
The political decision was triggered by a bitter diplomatic feud between Trump and German Chancellor Friedrich Merz over Europe’s refusal to provide naval support in the U.S.–Iran conflict.
While Berlin and Washington clash over macro-level NATO burden-sharing, the ZEW study proves that it is ordinary German civilian workers, local business owners, and municipal treasuries that will ultimately bear the brunt of the geopolitical fallout.
