The Dollar's Rally in a Trade War World: Navigating Uncertainty with Currency Strategies

As the U.S. navigates a labyrinth of shifting trade policies and unresolved tariff disputes in July 2025, the greenback has emerged as a key beneficiary of the resulting uncertainty. With the specter of 10–46% tariffs looming over trading partners and legal battles complicating the administration's strategy, the U.S. dollar (USD) has strengthened across major pairs, driven by inflationary pressures, terms-of-trade gains, and safe-haven demand. For investors, this volatility presents both risks and opportunities—a dynamic explored below through the lens of technical indicators, central bank policies, and historical precedents.

Policy Uncertainty Fuels USD Strength

The ongoing trade negotiations exemplify a classic “wait-and-see” scenario, where delayed decisions amplify market anxiety. Legal challenges to the Trump administration's tariff authority—such as the Court of International Trade's ruling against “Liberation Day” levies—have introduced further unpredictability. This uncertainty has pushed the Economic Policy Uncertainty Index to record highs, with traders pricing in a 15–18% average tariff rate by year-end.

The USD's ascent is best visualized through its correlation with tariff volatility:

Central Banks: Anchoring or Amplifying the Rally?

The Federal Reserve's response to tariff-driven inflation has been pivotal. Despite a 0.3% GDP contraction in early 2025, the Fed has delayed rate cuts until September 2025, citing sticky core inflation (3.6% as of Q3). This stance has supported the USD's interest-rate advantage over peers like the euro and yen, where central banks face weaker growth and policy constraints.

Meanwhile, the Bank of Japan's 2024 rate hike—a failed attempt to stabilize the yen—highlighted the fragility of carry trades. With the yen plummeting 12% in 2024, USD/JPY has surged to 160, a level last seen during the 2008 crisis.

Technical Indicators: Where Is the USD Headed?

Technical analysis reveals three key trends:
1. USD/CNY: The yuan's devaluation to 7.34 since mid-March .34 has been a USD tailwind, with further depreciation expected as China absorbs retaliatory tariffs.
2. EUR/USD: The euro has fallen to 1.05, nearing parity, as the ECB's policy divergence with the Fed and Eurozone trade deficits weigh.
3. USD/JPY: Resistance at 160 could push toward 165 if yen liquidity strains persist.

Historical Precedents: A Pattern of Dollar Strength in Trade Wars

Past trade conflicts, such as the 2018–2019 U.S.-China tariff war, show a consistent pattern: the USD gains 5–10% against major currencies during escalation phases, then corrects modestly as deals near. For instance, the DXY rose 8% between 2018 Q3 and 2019 Q1 before stabilizing.

Conclusion: Profiting from Policy Crosscurrents

The USD's rally in 2025 reflects a confluence of tariff-driven inflation, central bank divergence, and risk aversion. While the Fed's resolve to combat inflation supports dollar strength, geopolitical developments—such as a potential 90-day tariff reprieve—could trigger corrections. Investors should remain nimble, using technical levels and ETFs to navigate this landscape. As history shows, trade wars may end, but the USD's role as a refuge persists—until policy clarity finally arrives.
