Container ships at port representing US trade and tariff policy

Trump's 10% global tariff program has been struck down a second time in 2026, this time by a federal trade court that concluded the administration misread the law it used to justify the sweeping import tax. The ruling lands on a Friday morning when US stock futures are already higher on tech earnings optimism and traders prepare for the monthly jobs report, but it adds a fresh layer of policy uncertainty that traders and businesses will need to price over the coming days. This article is for educational purposes only, not financial advice.

TL;DR

  • The US Court of International Trade ruled 2-1 on Thursday May 7 that Trump's 10% across-the-board tariffs are unlawful, concluding the administration misread Section 122 of the Trade Act of 1974.
  • The ruling is the second major legal blow to Trump's tariff regime this year. The Supreme Court struck down an earlier set of tariffs in February 2026.
  • The court granted an injunction for two small businesses and the state of Washington. The larger coalition of states was dismissed on standing grounds.
  • US stock futures were rising Friday morning as traders also weighed tech sector earnings and awaited the monthly jobs report. The tariff ruling removes one layer of import-cost uncertainty for businesses, but Trump can appeal, seek a stay, or attempt yet another legal authority.
  • The tariff by statute was already set to expire in late July 2026, which limits but does not eliminate the near-term market significance of this ruling.

What happened

The Court of International Trade delivered a 2-1 decision Thursday ruling that Trump's 10% global tariff is unlawful. ABC News and the New York Times both confirmed the ruling Thursday evening. The judges found that the Trump administration misread the phrase "balance-of-payments deficits" in Section 122 of the Trade Act of 1974, the legal provision used to justify the tariff after the Supreme Court had already struck down an earlier tariff round.

The majority wrote that Congress in 1974 identified specific deficit measures, not the current-account measure the administration had relied on, and that the administration's interpretation was incorrect. The court granted injunctive relief for the two small business petitioners and the state of Washington, but dismissed the broader coalition of states for lack of standing, which limits the immediate scope of the ruling's practical effect.

Politico reported that the ruling came just months after the Supreme Court affirmed a prior Court of International Trade decision blocking Trump's first-round tariffs. In plain terms, this is the administration's second attempt at a legal basis for sweeping global import taxes, and the second time a federal court has concluded that basis was not valid. CNN and The Guardian independently confirmed the same outcome Thursday evening.

The 10% tariff had taken effect in February 2026 and was set by statute to expire in late July. Bloomberg reported the ruling in a video segment Friday morning, framing it against a backdrop where US stock futures were still moving higher as traders also focused on the tech sector earnings outlook and the monthly jobs report.

Trump tariffs ruled unlawful: why markets moved

The immediate reaction in futures is constructive, but the picture is more complex than a simple relief rally. US stock futures were already rising Friday morning driven largely by tech earnings momentum, and Bloomberg's markets wrap described investors weighing the tariff ruling alongside other drivers including the monthly employment report.

The ruling matters to markets because the 10% global tariff had been adding to input-cost uncertainty for importers, manufacturers, and retailers since February. A court ruling that removes or suspends the tariff, even if the practical window is narrow before the July statutory expiry, reduces that uncertainty in the near term. Earlier analysis by Wells Fargo had estimated that a ruling against the tariffs would boost S&P 500 earnings before interest and taxes by approximately 2.4% in 2026 versus the prior year.

However, the market cannot yet treat this as a fully resolved event. Trump retains other legal options for trade policy, including other tariff statutes. The administration could seek a stay of the injunction, pursue an appeal, or use a different authority to reimpose the tariff or a similar measure. Bloomberg noted the ruling context in the same breath as the Trump administration's push for a peace deal with Iran, reflecting how many simultaneous risk variables traders are currently managing alongside the cross-asset setup covered in US-Iran Hormuz Fire Exchange Puts Ceasefire at Risk and Sends Oil Back Above $100.

Implications for the most impacted trader cohorts

US equity and index-futures traders: The ruling is a modest positive for stocks on the margin because it removes one form of cost pressure on US importers and supply chains. Consumer discretionary, industrials, and tech hardware names that source heavily from abroad stand to benefit most if lower import costs flow through to margins. The key qualification is that the tariff was already set to expire in July, so the incremental impact compared with what the market had already partly priced is limited.

Sector-rotation traders: Companies with heavy import exposure, such as electronics assemblers, apparel retailers, and auto parts suppliers, face less near-term cost uncertainty. However, if Trump moves quickly to reimpose similar tariffs through an alternative legal channel or executive action, that benefit can reverse just as fast.

Fixed income and macro traders: The ruling removes one inflationary input. If import costs ease, it becomes marginally easier for the Federal Reserve to consider rate cuts later in the year. That said, the jobs report due Friday and persistent energy-price pressure from the Iran conflict are likely more important near-term drivers of rate expectations than this ruling alone.

Global trade and FX traders: Trading partners and foreign governments will also watch whether the administration finds another path to tariff enforcement. A clean legal defeat with no clear replacement would weaken the dollar as a tariff-threat vehicle and ease pressure on currencies of export-heavy economies. A rapid legal appeal or substitute tariff announcement would reduce that dollar-softening effect.

Potential positives vs negatives

Potential positives

  • The ruling removes a legally contested 10% tax on most imports and reduces cost uncertainty for thousands of businesses that had been absorbing or passing on those costs since February.
  • If the ruling stands, S&P 500 earnings estimates may be revised modestly higher for sectors with meaningful import exposure.
  • Reduced tariff pressure also eases one inflationary input, which could marginally improve the Federal Reserve's policy flexibility over the next few quarters.
  • The ruling adds to legal precedent that constrains the executive branch's use of emergency trade statutes for broad sweeping tariffs, which may reduce the risk of similar unilateral moves in the near term.

Potential negatives

  • The injunction is narrow in scope. It applies to the two small business petitioners and the state of Washington. Broad market relief depends on how quickly the ruling is applied more widely or how the administration responds.
  • Trump can appeal, seek a stay, or use another statutory authority. CNN noted that this is the second time a replacement tariff plan has been struck down, which may prompt a more aggressive search for an alternative legal basis.
  • The 10% tariff was already set to expire in late July, so the practical relief window before the statutory expiry is short even if the ruling holds.
  • Trade policy uncertainty does not disappear. Markets may still price residual risk that a new tariff instrument appears before or after the July expiry date.

What could happen from here

Base case: The ruling stands for now, the administration files an appeal but does not immediately reimpose the tariff through another mechanism, and markets treat the outcome as a modest positive for import-sensitive sectors while staying focused on the jobs report and energy backdrop. Would be confirmed by: No rapid executive action or replacement tariff order within the next few days, the injunction remaining in effect, and equity futures holding or extending their Friday gain into the regular session. Would be invalidated by: A rapid administrative response, a new executive order targeting similar trade flows, or a stay granted to the administration that keeps the tariff in effect while the appeal proceeds.

Upside case: The administration chooses not to fight the ruling and Congress does not move quickly to pass a legislative tariff replacement. In that scenario, markets reprice import costs lower across affected supply chains, S&P 500 earnings estimates move up modestly, and the dollar faces mild depreciation pressure as the tariff threat premium unwinds. Would be confirmed by: Quiet response from the White House, no rapid legal challenge to the injunction, and sector rotation toward import-heavy consumer and tech hardware names. Would be invalidated by: Any credible new tariff announcement or expedited appellate review that signals the administration is moving quickly to preserve a similar trade barrier.

Downside case: The administration files for an emergency stay, argues for appellate reversal, and signals it will use an alternative tariff authority. In that scenario, the ruling's practical effect is limited or eliminated before it can change business behavior, and markets return to pricing continued import cost uncertainty. Would be confirmed by: A rapid court filing for a stay, public statements from senior White House officials pledging to restore equivalent tariff levels through another route, and commodity and supply-chain sector prices giving back any post-ruling gains. Would be invalidated by: A measured or muted White House response that concedes legal ground and avoids an immediate replacement measure.

What to watch next

  • Whether the Trump administration files for an emergency stay of the injunction or announces an appeal within the next 24 to 48 hours.
  • Whether the White House signals any intent to reimpose equivalent tariffs through a different statutory authority, executive order, or Congressional action.
  • The April jobs report due Friday, which alongside the tariff ruling and the Iran situation shapes the full macro context for the US equity open.
  • How import-heavy sectors, including consumer electronics, apparel, and industrial components, trade in the Friday regular session compared to the broader market.
  • Any appellate-court or Supreme Court scheduling moves that could alter the timeline of the ruling's practical effect.

FAQ

Why were Trump's 10% tariffs ruled unlawful?

The Court of International Trade concluded that the administration misread the phrase "balance-of-payments deficits" in Section 122 of the Trade Act of 1974. The court found that Congress defined balance-of-payments deficits in specific technical terms in 1974 that do not match the current-account measure the administration relied on.

Does this ruling end Trump's tariff policy?

Not necessarily. The ruling strikes down the specific 10% global tariff enacted under Section 122. The administration can appeal, seek a stay, or attempt to reimpose tariffs through a different legal authority. The tariff was also set to expire in late July 2026 by statute, so the practical window for relief before expiry was already limited even before the ruling.
