BCA Warns Trade Escalation Could Return in 2027, Cites Iran-Linked Energy Risk Near Term

BCA Research projects that U.S. trade tensions will remain fairly constrained through 2026 due to legal and political checks, but could reopen after the next political cycle in 2027. A recent Supreme Court ruling narrowing the president's emergency-tariff authority, together with midterm election dynamics, makes a large near-term tariff escalation unlikely. Instead, BCA flags geopolitical risks tied to Iran and a roughly 38% probability of a major oil shock as the dominant market threat in the near term, which could keep investors focused on energy markets, inflation, and safe-haven U.S. assets.

Key Points

  • BCA expects U.S. trade tensions to stay fairly contained through 2026, with the risk of renewed escalation increasing in 2027.
  • A recent Supreme Court ruling limited the president's emergency tariff authority, reinforcing Congress' role and constraining aggressive tariff use.
  • Geopolitical risks tied to Iran and oil supply disruptions, with BCA assigning roughly a 38% probability of a major oil shock, are seen as the more dominant near-term market threat.

Overview

BCA Research says U.S. trade tensions are likely to stay relatively muted through 2026 before the risk of renewed escalation rises in 2027. The firm points to recent legal limits on executive emergency tariff powers and political pressures around the midterm cycle as factors that constrain the administration's ability to impose broad, aggressive tariffs in the near term.


Legal and political constraints

In an analysis published by BCA, the firm highlights a U.S. Supreme Court ruling on Friday that curtailed the use of emergency powers to levy wide-ranging tariffs. According to BCA, that decision reinforces Congress' primacy over trade policy and narrows the administration's latitude to unilaterally raise tariffs on a sweeping basis.

Combined with the electoral dynamics of the midterm season, the court's decision contributes to an environment in which a major trade escalation is unlikely this year, even as the president pursues measures aimed at maintaining a tougher trade posture.


Policy tools and likely trajectory for tariffs

Given the constraints, BCA expects policymakers to fall back on narrower instruments. The firm says temporary tariffs implemented under existing statutory trade authorities are the more probable route. Those steps could lift the effective U.S. tariff rate modestly, but any sustained or larger increases would encounter congressional approval hurdles and political friction that may lead to subsequent easing.


Geopolitical energy risk takes precedence

While trade policy remains an area of uncertainty, BCA argues that near-term market attention is more likely to center on geopolitical risks tied to Iran and the potential for disruptions to oil supply. The research shop quantifies the risk by assigning roughly a 38% probability to a major oil shock.

BCA notes that tensions between the U.S. and Iran have risen recently amid stalled nuclear talks and a U.S. military buildup in the Gulf, and that the president has warned of the possibility of limited strikes. Markets have already reacted to those developments, driving oil prices higher amid fears of a broader regional conflict and attendant supply interruptions.


Implications for markets and policy

Given the combined legal, political, and institutional checks from the courts, Congress and the Federal Reserve, BCA suggests policy uncertainty tied to trade could be lower than in earlier phases of the U.S.-China trade confrontation. That institutional framework, the firm says, may reinforce the safe-haven appeal of U.S. Treasuries and the dollar during episodes of global stress.

Nevertheless, BCA warns that tariffs could intensify again once the political cycle shifts. For the immediate horizon, the firm advises investors to prioritize geopolitical energy risks and wider macro conditions. U.S. equities and oil markets are identified as the main domains to watch for signs of shifting risk.


Near-term political considerations

BCA also observes that the president may pursue limited trade truces or small-scale agreements ahead of elections to temper inflationary pressure and steady corporate sentiment. That tack would make tariffs a secondary driver of market moves in the near term, even if the administration retains a posture of trade toughness.

Overall, BCA's view compresses the near-term trade-threat scenario: legal and electoral constraints are likely to moderate tariff escalation through 2026, while energy-related geopolitical shocks, notably those linked to Iran, present a more immediate and material market risk.

Risks

  • Possibility of a major oil shock linked to rising tensions with Iran - impacts energy, inflation, and oil markets.
  • Tariff escalation after political cycle changes could reintroduce trade-driven volatility - impacts U.S. equities and international trade-exposed sectors.
