Tariffs as Demand-Side Disinflationary Shocks: Reassessing Inflationary Risks and Portfolio Positioning in a Trade-War-Driven Economy

The global economic landscape in 2025 is defined by a paradox: tariffs, often framed as inflationary tools, are increasingly acting as demand-side disinflationary shocks in trade-war scenarios. This counterintuitive dynamic has reshaped inflationary risks and forced investors to recalibrate their strategies. As the U.S. and its trading partners navigate the fallout of Trump-era tariffs, the interplay between reduced aggregate demand and supply-side disruptions has created a complex environment for asset allocators.

The Disinflationary Paradox of Tariffs

Tariffs are traditionally viewed as inflationary due to their direct impact on consumer prices. However, empirical evidence suggests a more nuanced reality. According to a report by the San Francisco Fed, higher tariffs often act as aggregate demand shocks, reducing economic activity, raising unemployment, and depressing consumer and investor confidence. This disinflationary effect was historically observed in the U.S. before World War II, where a permanent 4-percentage-point tariff increase reduced inflation by 2 percentage points. The mechanism is straightforward: tariffs reduce trade volumes, dampen business investment, and shrink household purchasing power, all of which curb inflationary pressures in the short term.

Yet this dynamic is not universal. A separate Federal Reserve study highlights that trade disruptions-particularly those affecting intermediate goods-can sustain higher inflation for longer periods. When firms face supply chain bottlenecks, marginal costs rise, and production efficiency declines, leading to persistent cost-push inflation. This duality underscores the importance of context: tariffs on final goods may disinflation, while those on intermediate goods risk prolonging inflationary cycles.

The Trump Tariff Legacy: Economic Drag and Inflationary Tensions

The Trump-era trade war has left a lasting imprint on the U.S. economy. By 2025, the weighted average applied tariff rate had surged to 18.1 percent, the highest since 1941. This policy shift has reduced U.S. GDP by an estimated 0.8 percent, with cascading effects on employment and household budgets. Tariffs have raised $174 billion in revenue by September 2025, but the long-term costs-reduced output, lower incomes, and 715,000 lost jobs-outweigh these gains.

The inflationary implications are equally significant. A 2025 global economic assessment notes that U.S. core CPI inflation is projected to reach 4.1 percent year-over-year by year-end, driven by cost-push pressures from tariff-induced supply chain distortions. This tension between demand-side disinflation and supply-side inflation highlights the fragility of the current economic equilibrium.

Portfolio Positioning: Navigating Uncertainty Through Diversification

Investors have responded to this volatility with a strategic shift toward defensive positioning. JPMorgan recommends an overweight in bonds and a neutral stance on equities, citing elevated valuations and tariff-related risks. Similarly, BlackRock advocates for diversifying risk through bonds and liquid alternatives to offset the sharp pullback in U.S. equities. Defensive factors-low volatility, quality, and yield are now central to managing downside risk in a stagflationary environment.

Commodities have also gained traction as hedges. Gold, in particular, is seen as a safeguard against the rising risk of stagflation-a scenario where high inflation coexists with weak growth. Meanwhile, Invesco highlights opportunities in European and Chinese equities, assuming fiscal stimulus can offset trade-war drag.

Sector Rotation: From Tech to Traditional Value

The most striking portfolio adjustment has been the sector rotation away from high-growth technology and AI stocks toward traditional, undervalued industries. From 2023 to 2025, investors have favored sectors with stable earnings and tangible assets, such as Utilities and Healthcare. Financial services, energy, and industrials have also attracted renewed interest due to their alignment with value and cyclical themes.

This shift reflects a broader recalibration of market dynamics. As global economic growth moderates and central banks adjust policies, the emphasis on earnings over speculative growth has intensified. The cooling of AI-related enthusiasm further underscores this trend, with investors prioritizing fundamental value over long-term hype.

Conclusion: Balancing the Risks

The trade-war-driven economy of 2025 presents a dual challenge: mitigating the disinflationary drag of reduced demand while managing the inflationary risks of supply-side disruptions. For investors, the path forward lies in diversification, defensive positioning, and a nuanced understanding of sector dynamics. As tariffs continue to reshape global trade relationships, the ability to adapt to shifting economic tides will remain paramount.
