The Looming Threat of Stagflation: How Trump’s Tariffs Could Stifle the US and Global Economies

The global economic landscape is facing a period of uncertainty, with concerns mounting over the potential for stagflation – a dreaded scenario characterized by the toxic combination of stagnant economic growth, high unemployment, and persistent inflation. This challenge is particularly concerning in light of the most recent implementation of tariffs by the Trump administration announced on April 2, 2025. A new framework of “reciprocal tariffs” on imports from nearly every country was announced, citing a national emergency due to large and persistent trade deficits. A baseline tariff of 10% will take effect on April 5, 2025, on imports from most countries, including Singapore. This baseline will increase for approximately 57 countries with which the US has the largest trade deficits, with these higher “individualized reciprocal tariffs” ranging from 11% to as high as 50% and taking effect on April 9, 2025. 

To fully grasp the potential dangers of Trump’s tariffs, it’s crucial to first understand the phenomenon of stagflation, a concept that is well covered in our JC Econs Tuition (A-Level). This economic condition is defined by a trifecta of negative indicators: sluggish or non-existent economic growth, high levels of unemployment, and persistently high inflation. This combination is particularly problematic as it deviates from typical economic patterns where slow growth and high unemployment usually lead to decreased aggregate demand and, consequently, lower inflation. 

The simultaneous occurrence of these issues makes recovery exceptionally difficult for policymakers because the conventional tools used to combat either inflation or unemployment can inadvertently worsen the other as illustrated by the Phillips Curve shown below (covered in our IB Economics Tuition programme), which posits an inverse relationship between inflation and unemployment.

This presents a dilemma where measures designed to curb rising prices, such as increasing interest rates, can lead to even higher unemployment, while policies aimed at boosting employment might cause sky-rocketing inflation. This creates a complex challenge for central banks and governments seeking to restore economic stability.

History offers several examples of stagflation, with the most prominent being the experience of the United States during the 1970s oil crisis. This period saw a significant surge in oil prices due to geopolitical events, which acted as a major supply shock, increasing costs across various industries. Coupled with specific government policies, this led to a prolonged period of both high inflation and high unemployment, severely impacting the American economy. Other instances of stagflation include Japan in the late 1990s and, more recently, Zimbabwe. The 1970s experience in the US serves as a stark reminder of how external shocks combined with policy responses can create a sustained period of economic difficulty.

The primary theoretical explanations for stagflation often revolve around supply shocks, such as a sudden increase in the price of a crucial commodity like oil, or misguided government policies that inadvertently hinder production while expanding the money supply. Unlike typical inflationary periods driven by strong demand, stagflation frequently arises from disruptions to the supply side of the economy or from policy missteps that stifle economic activity while still contributing to rising prices.

Tariffs, by their very nature, function as a tax imposed by a government on companies that import goods from other countries. These added costs for importing businesses are often passed on directly to consumers through higher prices for the goods they purchase. This mechanism directly contributes to inflationary pressures within the economy. Furthermore, tariffs levied on intermediate goods and raw materials, which are used by domestic businesses in their production processes, can increase the overall cost of manufacturing. For instance, tariffs on imported steel would raise the cost for American car manufacturers, who would likely then increase the prices of their vehicles for consumers.

The sheer scale and scope of Trump’s “Liberation Day” tariffs, which are being imposed on about 90 countries, suggests the above effects will be amplified many times over, stoking inflation and dampening purchases. In addition retaliation by trading partners such as China will weigh down on US’s exports, and thus likely cause a contraction to or a slowdown of the US economy, realising the nightmare scenario of stagflation.

The potential for the US tariffs to trigger stagflation is not limited to its domestic economy; these policies also carry the risk of having a significant ripple effect on the global economy. When the US imposes tariffs on goods from other countries, countries like China, that retaliates also harm their own economies by increasing prices for consumers and businesses, potentially leading to slower growth and even inflation. Furthermore, disruptions to global supply chains, triggered by US tariffs, can have a cascading effect, impacting multiple economies simultaneously as businesses struggle to access necessary inputs or face higher transportation costs. The interconnectedness of the global economy suggests that the stagflationary pressures originating from US tariffs are unlikely to remain confined within its borders, potentially creating a negative feedback loop that impacts global growth and leads to stagflation in multiple countries.

In conclusion, the tariffs imposed by the Trump administration pose a significant risk of contributing to stagflation both in the United States and across the global economy. The mechanisms through which tariffs fuel inflation, coupled with their potential to disrupt global supply chains and hinder international trade, create a dangerous combination that could lead to a period of slow economic growth and persistently high prices. The historical example of the 1970s stagflation in the US serves as a stark reminder of the potential for such a scenario to inflict lasting economic pain. As nations navigate an increasingly complex global landscape, a careful consideration of the broader economic implications of protectionist measures is crucial to avoid the perils of stagflation.
