On Friday, February 20, the Supreme Court struck down a major portion of the tariffs enacted last year.

On Saturday, February 21, a new 15% “global” tariff on all countries was announced.

  • What exactly happened?
  • What does this mean for markets and the economy?
  • What could happen next?

Providing clarity during uncertain moments is part of our commitment to simplifying the complex and helping you and your family make informed decisions with confidence. The following perspective is intended to break down the situation in a straightforward way.

 

What Happened?

After taking office last year, President Trump announced sweeping “reciprocal tariffs” — up to 50% on imports from certain countries and a baseline 10% tariff on imports from most other nations. These “Liberation Day” tariffs were not well-received on Wall Street and contributed to a sharp market correction. Many were later delayed or reduced, but the nation’s overall average tariff rate still reached approximately 13% by year-end — the highest level since before World War II.

People can reasonably disagree about whether tariffs represent good policy. However, at their core, tariffs function as a tax on imported goods and services. When U.S. businesses purchase products from overseas, that tax becomes an added cost alongside the purchase price. While some industries benefit from protection, others face higher expenses.

As a result, businesses and several states filed lawsuits challenging the legality of the tariffs, and those cases ultimately reached the Supreme Court.

The legal issue centered on the law used to impose the tariffs: the International Emergency Economic Powers Act (IEEPA). Passed in the 1970s, this law allows a president to declare a national emergency in response to unusual threats to national security, foreign policy, or the economy and grants certain authority over international commerce.

However:

  • The IEEPA does not specifically mention tariffs.
  • It had never previously been usedto impose tariffs.
  • Tariffs are considered a form of taxation, and taxation authority belongs to Congress.

Because of these factors, the Supreme Court concluded that the President exceeded his authority. The Court stated that IEEPA’s authority to “regulate importation” does not include the power to impose taxes such as tariffs. As a result, all reciprocal tariffs enacted under that law were declared null and void.

 

The End of the Story?

The Court’s decision struck down tariffs implemented under IEEPA — but not all tariffs in general.

Several other laws allow presidents to impose tariffs through different procedures. Just one day after the ruling, a new 15% global tariff was announced under another legal authority. Some countries now have lower tariff rates than before, while others are higher.

 

What This Means for Markets and the Economy

Markets reacted negatively to major tariff announcements last year, and volatility returned following the recent developments. Additional tariff announcements are possible, so investors will continue monitoring policy changes closely.

However, there are reasons to expect a more muted long-term market reaction:

  • Laws currently being used provide less flexibilitythan IEEPA.
  • The new 15% tariff includes a 150-day expiration, after which Congress must decide whether to extend it.
  • Other tariffs may take time to implement because they require formal government investigations.

Economic implications are more complex.

Potential positives:

  • The Congressional Budget Office estimated tariff revenue could reduce the national deficit by approximately $3 trillion over ten years.
  • Tariffs may have helped support negotiations with countries such as Japan, South Korea, India, and the United Kingdom.

Potential challenges:

  • The U.S. goods trade deficit increased over the past year.
  • Federal Reserve research suggests nearly 90% of tariff costs were borne by U.S. businesses and consumers.

If tariffs decline, the resulting effects on growth and inflation could ultimately be supportive for markets.

 

A Major Unknown: Possible Refunds

Another unresolved issue involves refunds.

Because tariffs imposed under IEEPA were ruled illegal, businesses that paid them may be entitled to reimbursement. The total potential refunds are estimated at approximately $175 billion.

That outcome would represent both a significant injection of money into the economy and a substantial impact on the federal deficit.

The Supreme Court did not decide this issue, so further court action is likely. Timing and outcomes remain uncertain.

 

What Comes Next

More tariff-related volatility is possible. However, one principle remains consistent: A thoughtful, long-term financial strategy remains the most effective tool in both favorable and challenging market environments.
