International Stocks Beat US by 9% in 2026 on Weak Dollar

International equities have outpaced US shares by roughly nine percentage points in 2026, as a structurally weaker dollar, global capital rotation, and resurging non-US corporate earnings combine to deliver the clearest challenge to American equity dominance in more than a decade.

What Happened

The outperformance gap has been building since the US Dollar Index (DXY) shed 9.4% in 2025 — its worst annual decline in over a decade — dragged lower by the economic uncertainty generated by the sweeping tariff regime imposed in April 2025 and its subsequent reversal. That structural re-rating of the dollar has continued to benefit international investors in 2026 even as the DXY has partially recovered, trading at 100.91 on July 14, still well beneath the multi-year highs of 114 set in 2022.

The math is straightforward: when the dollar weakens, foreign-currency earnings, dividends, and capital gains convert to more dollars upon repatriation. A US investor holding iShares MSCI EAFE ETF (EFA) or Vanguard Total International Stock ETF (VXUS) captures both local market gains and currency translation benefits. Over the trailing 12 months through early March 2026, the iShares Core MSCI EAFE ETF (IEFA) returned 22.88%, outpacing the S&P 500's 17.69% over the same stretch — and the year-to-date 2026 gap has since widened further.

Regional Breakdown

Japan has been the headline performer. The Nikkei 225 has surged 33.6% year-to-date through mid-July in local currency terms, lifting the MSCI EAFE's developed-market aggregate. Canada's TSX has added 11.2%. European bourses have broadly extended multi-year runs, with the pan-European Stoxx 600 hitting fresh 52-week highs in early July.

Emerging markets delivered a powerful first-half performance, with the iShares MSCI Emerging Markets ETF (EEM) gaining approximately 23.8% through June 30. Within that cohort, Taiwan and South Korea — the world's dominant AI hardware manufacturers — delivered the strongest equity returns globally, as surging demand for advanced semiconductors tied to artificial intelligence infrastructure buildout created durable earnings tailwinds outside the United States.

Technology has been the sector that most starkly illustrates the reversal of leadership. The MSCI Emerging Market Technology index gained more than 90% in the first six months of 2026, while European technology shares climbed 44.8% — both dwarfing the 19.4% advance posted by their US counterparts.

The Dollar Dynamic

The dollar's structural shift is central to the story. The DXY plunged to a four-year low in early 2026 before recovering partially, and as of February 2026 it remained 7.6% weaker than its December 2024 average. The euro held near $1.14 through mid-July 2026, pulling back from highs near $1.19 reached in late winter. The yen, meanwhile, has stayed soft — 100 yen converts to approximately $0.62, compared to $0.68 a year earlier — which partially offsets Nikkei gains in dollar terms but still positions Japanese equities well ahead of US benchmarks in USD-adjusted return calculations.

The mechanism is structural. Trade policy uncertainty surrounding the sweeping tariffs introduced in April 2025 — many of which were later struck down by the US Supreme Court in February 2026 — generated persistent questions about the credibility of the dollar as a reserve-currency anchor. Research published through the National Bureau of Economic Research has confirmed that tariff escalation, particularly when met with retaliation, correlates with immediate dollar depreciation, as risk premia and precautionary savings flows weigh on the currency even as import costs rise.

Capital Rotation

The investment community has responded with a meaningful reallocation. Bank of America research characterized 2026 as a "new world order" for international equity investors, as global institutions systematically reduce US exposure and build positions across European, Japanese, and Asian markets. The rebalancing reflects both valuation differentials — international markets have traded at a persistent discount to US multiples — and renewed earnings growth outside the United States, particularly in European industrials and Asian semiconductors.

What Comes Next

Three variables will determine whether international equity leadership persists through the second half of 2026. First, the dollar's trajectory: a sustained recovery in the DXY would compress international returns in USD terms and close the performance gap. Second, earnings delivery in Europe and Asia — the first half's gains partly reflect expansion in price-to-earnings multiples rather than purely fundamental earnings growth, which raises the bar for continuation. Third, the macroeconomic growth divergence between the United States and the rest of the world: consensus expectations project stronger growth momentum outside the US, particularly in Asia, supported by domestic stimulus and AI-linked capital investment.

Outlook

The nine-percentage-point gap between international equities and the S&P 500 in 2026 reflects a confluence of dollar weakness, capital rotation, and a broadening of technology leadership beyond US borders. Nikkei 225, European technology, and emerging market semiconductors have all posted returns that dwarf their American equivalents. Whether the gap narrows in the second half hinges on whether the dollar stabilizes, earnings in international markets validate current valuations, and global growth continues to outpace US economic expansion. For the first time since the 2010s, the default case for US-centric equity allocation faces sustained structural challenge.
