Stephen Roach Warns “America First” Protectionism Could Drive U.S. Toward Stagflation

In a recent MarketWatch opinion piece, economist and columnist Stephen Roach warns that the United States’ shift toward an “America First” trade stance could push the economy into an extended period of stagflation — a damaging mix of sluggish growth and elevated inflation. Roach frames this risk as a consequence of protectionist policies that amount to a structural decoupling from global trade networks rather than a temporary disruption.

From Temporary Shocks to Permanent Decoupling

Roach contrasts the short-term supply-chain interruptions experienced during the COVID-19 pandemic with a more fundamental, lasting change driven by protectionist trade policy. While pandemic-related problems were episodic and tied to specific disruptions in production and logistics, the kind of policy-driven decoupling Roach describes would be permanent in nature. That distinction matters because temporary shocks usually recover as supply chains normalize; a permanent decoupling would systematically reduce the efficiency gains that globalization has delivered.

He highlights China as a primary example of where decoupling efforts have real consequences, and he suggests that decoupling pressure could extend even to closer partners in North America. The policy shift away from integrated, international production networks undermines decades of specialization and cost advantages that helped keep goods affordable and inflation lower.

Lost Efficiency and Inflationary Pressure

One concrete point Roach emphasizes is the loss of a persistent disinflationary effect that globalization once provided. Over the past decade, increased global integration and sourcing efficiencies contributed to roughly a 0.5 percentage point annual reduction in trend inflation for the U.S. economy. According to Roach’s argument, reversing that integration would eliminate that modest but meaningful downward pressure on prices.

The implication is straightforward: if the structural forces that helped restrain inflation are dismantled, inflationary pressures are likely to rise and remain elevated. At the same time, the protective measures intended to bolster domestic industry may not produce rapid productivity gains or immediate increases in output, leaving growth prospects muted. That combination — persistent inflation with lackluster growth — matches the classic definition of stagflation.

Why Reshoring Manufacturing Is Difficult

Roach also points out that reshoring production to the United States is neither quick nor easy. Establishing new production platforms, rebuilding supplier networks, and scaling industrial capacity all require time, capital, and technical know-how. These are complex undertakings that typically take many years to reach full maturity.

Furthermore, reshoring initiatives can be undermined by policy uncertainty. If firms face an uncertain regulatory and trade policy environment, they may delay or cancel planned investments. The result can be a slower and more fragmented reshoring process, which raises costs without delivering rapid increases in domestic manufacturing output. That lag exacerbates the risk of higher prices without commensurate growth.

Policy Uncertainty and Investment Behavior

Roach’s diagnosis also touches on how businesses respond to uncertainty. Companies weigh the costs and risks of relocating production, and unstable or unpredictable policy signals can dissuade long-term capital commitments. Even when governments offer incentives for reshoring, inconsistent or protectionist rhetoric can shrink the effective window for investment decisions, reducing the likelihood that reshoring will proceed at the speed or scale needed to offset the negative side effects of decoupling.

Economic Outlook and the Stakes

The central risk that Roach identifies is that protectionist trade policies could transform what were once manageable, transitory price effects into a permanent structural problem. The loss of global supply-chain efficiencies combined with delayed or insufficient reshoring would likely raise the baseline for inflation while failing to generate the robust growth needed to offset higher prices.

For policymakers and business leaders, the key takeaway from Roach’s analysis is the importance of weighing the long-term trade-offs of protectionism. Policies aimed at strengthening domestic industries must consider the time horizons, investment dynamics, and supply-chain realities involved. Otherwise, the United States may face a prolonged period in which economic growth falters while inflation remains stubbornly high.

Stephen Roach’s MarketWatch opinion serves as a caution: reversing globalization is not simply a political choice with immediate wins and losses. It can fundamentally reshape the balance of inflation and growth in ways that are hard to reverse, making the careful design and clear communication of trade and industrial policy essential to avoid the specter of stagflation.
