The Rate Differential: The Structural Engine of Dollar Strength

The divergence in monetary policy between the US Federal Reserve and the European Central Bank has reached levels in mid-2026 rarely observed since the eurozone crisis of 2011-2012. On one side, the ECB cut its deposit rate to 2.25% in June, signalling a possible second reduction in September to support a European economy whose growth remains fragile. On the other, the Fed is keeping its rates at elevated levels, constrained by persistent US inflation that refuses to durably converge toward the 2% target.

This transatlantic monetary gap constitutes the primary fuel behind dollar strength. In international finance, the uncovered interest rate parity (UIP) model predicts that a currency offering superior yield — in this case the dollar — tends to appreciate, all else being equal. The reality of capital flows confirms this theory: institutional investors and sovereign wealth funds are massively reallocating toward dollar-denominated assets, attracted by US bond yields that substantially exceed those offered by their European equivalents.

By way of comparison, a 10-year US Treasury bond currently offers a yield of approximately 4.50%, while the French OAT at the same maturity stands at 3.72% and the German Bund at 2.93%. This spread of more than 150 basis points versus the Bund — the eurozone benchmark — represents a substantial premium that portfolio managers cannot ignore over time.

EUR/USD: Anatomy of Persistent Pressure

The EUR/USD pair has had a turbulent trajectory since the start of the year. After displaying some resilience in the first half, supported by the relative vigour of the European economy and hopes of commercial de-escalation with Washington, it came under sharp pressure during June. The hawkish tone confirmed by the Fed’s monetary policy committee, combined with the adoption of the Turnberry commercial agreement by the European Parliament on June 16 — an agreement that maintains US surcharges on steel and aluminium through 2029 — reminded markets that the geopolitical and commercial context remains a structural source of volatility for the euro.

In early July, the pair is stabilising around 1.14, after having printed lows below 1.10 during peak periods of tension. The key technical resistance sits at 1.15, with immediate support at 1.13-1.12. Major investment banks display very divergent views: Capital Economics anticipates a return toward 1.10 by end-2026, while ING and BNP Paribas Wealth Management instead judge that a rebound toward 1.18-1.22 is plausible if the Fed were to pivot more quickly than expected.

This dispersion of forecasts reflects a fundamental reality: the dollar strength of 2026 rests on solid but fragile pillars. The rate differential is real and powerful; however, the US federal budget deficit — now exceeding 6% of GDP — and political tensions surrounding the Fed’s independence represent counterforces capable of eroding foreign investors’ confidence in the greenback over a 12-to-24-month horizon.

Sector and Geographic Impact: Winners and Losers

A structurally strong dollar produces asymmetric effects across asset classes and geographies. For a wealth management investor based in Europe, it is worth distinguishing three categories of effects.

European exporters — a contrasting picture. A weakened euro mechanically improves the price competitiveness of companies exporting outside the eurozone. Major groups in luxury, aerospace, and precision manufacturing benefit from a favourable conversion effect when repatriating revenue denominated in dollars. However, this advantage is partially neutralised by the US tariff surcharges still in force on certain sectors (steel, aluminium, automobiles), which weigh on the margins of exporters to the United States.

Emerging markets — under pressure. A strong dollar traditionally constitutes a headwind for emerging countries whose external debt is denominated in greenbacks. Servicing this debt mechanically becomes more expensive in local currency. Currencies like the Mexican peso, Brazilian real, or Indian rupee face depreciation pressure, with cascading effects on local equity markets and direct investment flows.

Commodities — the currency effect not to overlook. Gold, oil, and industrial metals are denominated in dollars. When the greenback strengthens, these assets become mechanically more expensive for non-US buyers, which can weigh on marginal demand. For a European investor, the euro-denominated performance of a gold ETF or commodities fund will therefore be reduced by however much the dollar has appreciated against the euro over the holding period.

Allocation Strategies in the Face of the Greenback

Faced with this context of a durably strong but potentially unstable dollar, three adaptation axes merit consideration from a medium-term wealth management perspective.

Capture the carry on US Treasuries without currency hedging. Short-to-medium term US Treasuries (3-7 years) offer an actuarial yield superior to their European equivalents, with AAA credit quality. For an investor anticipating a stabilisation or slight further strengthening of the dollar, maintaining an unhedged exposure on this sleeve allows capturing both the bond yield and the positive currency effect. This strategy does however carry a non-negligible exchange rate risk if the dollar were to reverse sharply.

Select resilient European exporters. Rather than broad exposure to the European equity market, the approach should target companies whose revenue structure directly benefits from a weaker euro — particularly in the luxury, pharmaceutical, and precision manufacturing sectors — while avoiding those whose supply chains are exposed to remaining US tariff surcharges.

Maintain a hedge position via gold. Despite the mechanical negative effects of a strong dollar on the gold spot price, the yellow metal plays its role as a safe-haven asset in scenarios of geopolitical stress or distrust toward the US financial system. Goldman Sachs maintains a target of $4,900/oz by end-2026, which, even accounting for the currency effect, offers attractive valuation potential for a European investor over a 12-month horizon.
