Tariffs to Slow US Economic Growth Without Significantly Cutting Trade Deficit

The effect on inflation will vary based on tariff scope, fiscal policy, and the Fed's actions.

Tariffs have long been a subject of debate in economic policy, with concerns about their effects on growth, inflation, and trade balances. As discussions around tariff policies continue, it's important to understand their potential consequences. This article explores the economic impact of tariffs, their influence on GDP, trade deficits, and inflation, as well as the broader implications for the US economy.

Tariffs and Their Impact on US Economic Growth

Higher tariffs are expected to slow down real GDP growth, affecting overall economic output and living standards. If tariffs reach significant levels, the economic impact could be severe, potentially leading to a recession.

According to economic projections, implementing a uniform 10% tariff increase along with a 60% tariff hike on Chinese imports could reduce the long-term level of US GDP by approximately 1.6%. This decline results from reduced trade efficiency, increased production costs, and disruptions to global supply chains.

The US economy grew at an annual rate of 2.5% in 2023, but analysts suggest that aggressive tariff policies could bring growth down to 1.3% in 2025. While these tariff hikes remain uncertain, even partial implementation could negatively affect the economy. Market analysts are already factoring in a potential GDP slowdown in their forecasts.

The Effect of Tariff Hikes on GDP Growth

Economic models predict that higher tariffs will unambiguously lower GDP growth. Specifically:

• A 10% uniform tariff increase is estimated to reduce GDP by 1.1%.
• A 60% tariff increase on Chinese imports is expected to lower GDP by 0.5%.
• Combined, these tariff hikes could permanently reduce the GDP level by 1.6%.

The likelihood of implementing China-specific tariffs is relatively high due to bipartisan support for policies aimed at reducing reliance on Chinese imports. However, businesses may mitigate these effects by shifting production to other countries, softening the overall economic impact.

According to a 2024 Congressional Budget Office (CBO) report, if tariffs on key industrial imports increase beyond 15%, US manufacturing output could decline by 3.2% over the next five years, with employment in the sector falling by 450,000 jobs.

Why Tariffs Won’t Reduce the US Trade Deficit

One of the primary goals of tariff policies is often to reduce the trade deficit. However, increasing tariffs is unlikely to achieve this objective.

The US trade deficit stood at $945 billion in 2023, the second highest on record. Despite previous tariff implementations, the deficit has not significantly declined due to capital inflows sustaining high levels of imports.

Tariffs may initially reduce imports, but the US dollar is likely to appreciate in response, making US exports less competitive and ultimately offsetting the intended effects. A historical example of this can be seen in the shale oil boom of the 2010s. While the US became a net exporter of oil and gas, the overall trade deficit did not shrink because the stronger dollar made other imports cheaper and exports less attractive.

For a meaningful reduction in the trade deficit, the US would need to focus on decreasing capital inflows rather than imposing trade restrictions.

How Tariffs Could Impact Inflation

Inflation is another critical factor influenced by tariff policies. The extent to which tariffs drive up prices depends on the fiscal and monetary policy response.

• If tariff revenue is used for tax cuts, inflationary pressures could rise, prompting the Federal Reserve to increase interest rates.
• Currency appreciation could counteract inflation but may harm US exporters by making their goods less competitive.
• Foreign retaliation in the form of counter-tariffs would likely lead to higher prices for US consumers.

Based on current projections, average inflation is expected to be around 2.0% from 2025 to 2029, with a slight increase to 2.2% in 2025 before dipping below the Federal Reserve’s 2.0% target in subsequent years. The full implementation of tariffs could push inflation up by another 1-2% over the long run.

A study by the Peterson Institute for International Economics found that the last round of trade tariffs raised consumer prices by 0.5% to 1.0%, costing the average US household an additional $500 per year in increased costs.

The Long-Term Consequences of Tariff Policies

Historically, the US has maintained relatively low average tariff rates, hovering around 2.5% in 2024. However, a full-scale tariff increase could push this rate above 15%, the highest level since the early 1930s.

While it's more likely that tariffs will increase modestly to around 5%, this would still be the highest rate since the 1960s. As of early 2025, market predictions estimate a 40% probability of this occurring.

Higher tariffs could also disrupt major US trading partnerships. The European Union and Canada, which collectively account for over $1.2 trillion in annual trade with the US, could impose retaliatory tariffs, further dampening economic growth.

Given these potential shifts, policymakers must weigh the trade-offs between protecting domestic industries and fostering long-term economic growth. Businesses, investors, and consumers alike should prepare for potential shifts in trade policy and their broader economic ramifications.

Conclusion: What Lies Ahead?

Tariff policies carry significant implications for economic growth, trade balances, and inflation. While they may serve as a tool for economic protectionism, their broader effects could slow GDP growth and push inflation higher without significantly reducing the trade deficit.

As the global trade landscape evolves, it remains crucial for businesses and policymakers to navigate these changes strategically. Whether tariffs will be fully implemented, modified, or repealed remains uncertain, but their economic consequences are clear: higher costs, lower growth, and complex trade dynamics.
