What’s next for U.S. tariffs?
The ultimate economic impact of the Trump administration’s tariffs will depend less on whether trade restrictions remain in place and more on how they are implemented and sustained over time. While the Supreme Court tariff ruling limits the use of emergency authorities, it does not signal a shift in the broader trade posture. Rather, it reshapes the form of trade policy, not its function, leaving effective trade barriers elevated.
Under President Trump, U.S. tariff policy has remained fluid, with periodic announcements targeting specific countries or industries. In some cases, these actions have resulted in negotiated trade outcomes. In others, proposed measures have been delayed, modified, or replaced, reinforcing uncertainty for businesses and investors around timing and scope—even when the broader posture remains intact.
Legal clarity does not necessarily translate into economic relief. “The key question is not whether tariffs can be imposed, but under which authority and how broadly” says Bovino. “Constraining the use of emergency powers reinforces Congress’s role in trade policy, but it does not eliminate the administration’s ability to pursue its trade objectives.”
Even with clearer legal boundaries, the macroeconomic implications may be limited. “From an economic perspective, it’s not a major game changer,” says Schoeppner. “Tariffs are already embedded into contracts, pricing and supply chain decisions.” While some measures could be adjusted or unwound over time, others – particularly those applied to broad commodity categories or reintroduced under alternative authorities – may remain in place, limiting the immediate impact on growth or inflation.
How tariffs could influence economic growth
It’s important to recognize that tariffs are only one of many forces shaping economic growth and inflation. While they are generally viewed by economists as a drag on activity, their impact to date appears manageable within the context of broader economic fundamentals.
Looking ahead, tariffs could contribute to more persistent – or “sticky” – inflation at the margin, which may lead the Federal Reserve to proceed cautiously with additional interest rate cuts. Even so, at current levels, tariffs alone do not appear sufficient to derail ongoing economic expansion.
