Economic forecast shows trade war's short-lived inflationary impact

The OECD forecasts that President Trump's trade war will cause economic growth to slow, particularly in the U.S. where growth is expected to fall to 1.6% this year, while inflation will temporarily rise to 3.9% by the end of 2025 due to higher import prices. Economists at Goldman Sachs similarly anticipate weak economic growth will prevent prolonged high inflation, although they caution that further tariff escalations into 2026 could alter this outlook; Fed Governor Waller expects any inflationary effects from tariffs to be temporary and most apparent in the second half of 2025.

Analysis

The macroeconomic outlook is increasingly shaped by trade policy, with forecasts pointing towards a period of stagflation, albeit potentially short-lived, as stagnant growth may counteract persistent inflationary pressures. The Organisation for Economic Co-operation and Development (OECD) projects U.S. economic growth to decelerate significantly to 1.6% this year from 2.8% last year, with further slowing anticipated into 2026, directly attributing this to trade war impacts. Concurrently, the OECD anticipates headline inflation to reach 3.9% by the end of 2025 due to higher import prices, before easing throughout 2026 as moderate GDP growth and higher unemployment take effect. This view is partially corroborated by Goldman Sachs economists, who expect weak GDP growth of just 1% this year to prevent prolonged high inflation, though they caution that renewed tariff escalations could extend inflationary pressures. Federal Reserve Governor Christopher Waller also anticipates that tariff-induced inflation will be a temporary phenomenon, primarily impacting the second half of 2025, while expressing optimism about underlying inflation trends and labor market resilience. The core dynamic suggested is that while tariffs may initially elevate prices, the resultant economic slowdown and rising unemployment could dampen wage demands and corporate pricing power, effectively causing the 'stag' component of stagflation to mitigate the 'flation'. The OECD's projections notably assume the extension of 2017 tax cuts and are sensitive to changes in U.S.-China tariff rates, underscoring the pivotal role of ongoing trade policy decisions in shaping economic outcomes.

Key Decisions for Investors

• Investors should closely monitor developments in U.S. trade policy and tariff implementations, as these are identified as primary drivers of the forecasted economic slowdown and inflation spike.
• Consider adjusting portfolio allocations to account for a potential U.S. GDP growth slowdown to 1.6% or lower, and a temporary rise in inflation to near 3.9%, which may favor assets less sensitive to economic cyclicality or those that perform well in disinflationary environments once the initial price shock subsides.
• Evaluate the impact of potentially higher unemployment and moderate wage growth on consumer demand and corporate earnings, particularly for sectors sensitive to discretionary spending.
• Factor in the consensus view that tariff-induced inflation will be temporary, peaking in late 2025 and easing in 2026, when assessing fixed income duration and inflation-protected security valuations.
