Eight Takeaways from the Supreme Court’s Tariff Ruling

On February 20, the U.S. Supreme Court ruled that the Trump administration’s tariffs issued under the International Emergency Economic Powers Act (IEEPA) are illegal. The ruling invalidates a big component of President Trump’s sweeping tariff program, including reciprocal tariffs and drug‑related tariffs on Canada, China, and Mexico. These measures were imposed under national emergency declarations.

While the Court did not explicitly order refunds to be paid — instead sending that decision to the lower courts — by some estimates this decision opens the door to potentially as much as $175 billion in tariff reimbursements to U.S. importers.

Here are some of our key takeaways.

1. Short-term stimulus jolt. Though mostly expected, the U.S. economy, key U.S. trading partners, and corporate America just found out they are getting a short-term stimulus boost. IEEPA had been used for an estimated roughly half of the tariffs imposed by the Trump administration. While the precise amounts are unclear, countries and companies will now play less. An overall U.S. tariff rate that had been expected in the low teens just a few months ago is now unlikely to reach double-digits, even after new replacement tariffs are imposed under different legal authority.
2. Intermediate-term effects are likely to be minimal. President Trump already revealed his tariff pivot, from IEEPA to Section 122 (which allows for 15% tariffs for 150 days) and Section 301 (which takes several months to investigate). LPL Research believes most of the IEEPA tariffs can be replaced by summertime (Evercore ISI’s policy research team believes 90% of tariffs could potentially be restored).
3. Trade policy uncertainty remains. While companies paying smaller tariffs is positive for profit margins and the Supreme Court ruling offers more clarity on the future path of tariffs, a lot of uncertainty remains. Markets will continue to debate whether lower courts will force the Treasury to issue refunds. In addition, it’s not clear what this decision means for trade negotiations and completed trade frameworks with other countries (notably, given the USMCA, this news doesn’t mean as much for imports from Canada and Mexico).
4. Inflation impact is murky. If tariffs have not affected inflation much on the way in, then it follows that they won’t affect prices much coming out. So, while benefits to inflation will likely be minimal, taking a point or two away from expectations for where tariff rates will eventually land can reasonably be expected to lower inflation by a few basis points.
5. Don’t expect Fed rate cut expectations to move much. The removal of tariffs reduces a source of friction in the real economy. Tariffs were expected to raise input costs, tighten profit margins, and weigh a bit on economic growth — slowing economic conditions are generally supportive for Treasuries. With that drag removed, growth may stabilize at the margin, and inflationary pressures embedded in the bond market could ease faster than markets previously expected. This changes the balance of risks around the Fed’s rate path and may lead to some modest repricing of rate cut expectations and incremental U.S. dollar weakness.
6. We would fade the stock market bounce in tariff losers. Given tariffs are already in the process of coming back in with President Trump’s announcement of a new 10% global tariff (that didn’t take long), we wouldn’t chase any rebounds in import-heavy consumer retailers. Given mixed post-decision reactions in retailers in Friday’s trading, it appears the market is onboard with this assessment. Among tariff losers, our preference would be to play homebuilders, industrials, and technology hardware/semiconductors over apparel retailers and automakers.
7. Treasury may face additional short-term funding pressure. For the Treasury market, this trade policy shift removes a meaningful — though not dominant — support to federal revenues and reopens questions about funding pressures at a time when deficits were already poised to remain in excess of $1.8 trillion annually. With less tariff income, the Treasury may need to increase issuance modestly, particularly in bills and shorter ‑dated notes, to offset the lost cash flow. This could put upward pressure on yields at the margin, especially in an environment where supply and demand dynamics were already being tested. The initial selloff in the Treasury market on the news was minimal, pushing 2-year and 10-year yields up by just 2-3 basis points (U.S. 10-year Treasury yield is 4.09% as of 3pm ET on February 20).
8. Refunds may introduce more near-term financing needs. Another key implication stems from the prospect of tariff refunds. Because the Court found the tariffs unlawful, many importers may now file refund claims, potentially up to $175 billion. Even if processed gradually, this creates a new near ‑term financing need for the federal government. Any meaningful issuance to bridge refund ‑related outflows would likely concentrate in the front end of the curve, steepening it modestly.

That’s where we see things now, but this situation is fluid. We will continue to bring updates as more information becomes available.
