The Dollar in a Trade War: Why the Reflex Bullish Trade May Be the Wrong One

The conventional wisdom about the US dollar in a trade war is that it strengthens. The logic is straightforward: tariffs reduce import volumes, narrow the trade deficit, and reduce the supply of dollars flowing to foreign exporters, driving up the currency’s value. That logic is correct — in the short run and under simplified assumptions. The 2026 tariff environment is neither short-run nor simple, and the dollar’s medium-term trajectory is considerably more uncertain than the reflex trade suggests.

Why the Reflex Dollar-Positive Trade May Be Wrong This Time

The immediate market reaction to tariff announcements typically produces dollar strength as risk-off flows dominate. That dynamic is playing out again in April 2026. But three structural factors distinguish the current episode from previous tariff cycles and create meaningful headwinds to sustained dollar appreciation.

First, the tariff regime is genuinely multilateral — not targeted primarily at one country. When the EU, Japan, Canada, and emerging market economies are all simultaneously facing tariff barriers, the retaliatory response is coordinated rather than fragmented. Coordinated retaliation means coordinated reduction in dollar-denominated trade settlement, which is the foundation of structural dollar demand. Several bilateral trade agreements have already begun denominating settlements in local currencies specifically to reduce dollar dependency; the current tariff environment accelerates that already-underway structural shift.

Second, the US current account deficit does not narrow overnight when tariffs are imposed. Supply chains take time to redirect. Consumption patterns take time to adjust. In the interim, Americans continue paying higher prices for the same goods but now with a tariff premium — a transfer of purchasing power to the government rather than foreign producers, but not a reduction in import volumes sufficient to meaningfully alter the balance of payments in the near term.

Third, foreign holders of US Treasury securities — the financing instrument of the current account deficit — now have additional political motivation to reduce their dollar reserve holdings. The tariff regime signals that the US is willing to weaponise economic relationships with allies; that signal accelerates the already-ongoing process of reserve diversification away from dollar assets by sovereign wealth funds and central banks in affected countries.

The Euro’s Ambiguous Position

The euro faces competing forces. On one side, EU retaliatory tariffs against US goods reduce dollar demand from European trade settlement. On the other side, the EU economy faces its own tariff-driven growth headwind, limiting the European Central Bank’s room to raise rates — which would normally support the currency. The net result is a EUR/USD pair that is likely to remain volatile and range-bound rather than trending in either direction, which benefits options traders more than directional investors.

The more interesting currency within the European context is the Swiss franc, which typically attracts genuine safe-haven flows in geopolitical stress environments without the growth headwind of the euro area’s export exposure. CHF positions have historically outperformed both EUR and USD in sustained trade conflict environments — the 2018–2019 cycle produced approximately 5–7% CHF appreciation against the dollar on a trade-weighted basis.

Emerging Market Currencies: The Commodity Divide

Not all emerging market currencies are equal in a tariff environment. Commodity exporters — particularly those supplying inputs that the US cannot easily source domestically — carry a structural advantage. Brazilian real, Chilean peso, and Indonesian rupiah each have commodity export backing that provides partial insulation from trade war dynamics. Commodity importers facing higher energy costs and weaker demand from their major trading partners sit in a fundamentally different position; the Pakistani rupee and Turkish lira face the most acute combined pressure.

The Chinese yuan deserves specific attention. Beijing has multiple currency management levers available and has historically deployed managed depreciation as a partial offset to tariff impacts on Chinese export competitiveness. A yuan depreciation of 5–8% would offset a significant portion of a 20–25% tariff on Chinese goods. The question is whether Beijing chooses that path — which risks capital outflow acceleration — or accepts the growth hit. The answer will shape the entire Asian currency complex in the months ahead.

Gold: The Currency That Is Not a Currency

Gold’s performance in the current environment reflects its dual role as an inflation hedge and a dollar alternative. Central bank gold buying, which reached multi-decade highs in 2022–2024 as geopolitical risk elevated, provides a structural demand floor. Tariff-driven inflation expectations provide the inflation premium. Dollar uncertainty provides the currency alternative premium. All three are simultaneously active in April 2026, which is why gold has outperformed both equities and bonds year-to-date.

The contrarian case against gold at current levels is that a rapid de-escalation of both the tariff regime and the Middle East conflict would simultaneously remove all three premium components. That is a genuine risk, but the probability of rapid, comprehensive resolution on two separate geopolitical fronts simultaneously is low enough that the gold premium appears fundamentally supported rather than speculative.

Outlook

Currency markets in 2026 are pricing a world in transition — away from dollar hegemony at the margin, toward multipolar reserve management, and through a period of tariff-driven trade disruption that has no clean historical template. Investors who maintain rigid dollar-centric assumptions about safe-haven behavior may find that the map no longer matches the terrain. Diversified currency exposure, inflation-linked assets, and selective commodity currency positions offer better risk-adjusted characteristics than either concentrated dollar longs or outright dollar shorts. The dollar’s role is changing, not ending — and the speed of that change has just accelerated.
