World-Wide Wednesday: AI Leadership, Energy Relief and the Return of Country Selection

International equity ETFs rallied selectively over the past month as investors balanced geopolitical relief, lower energy-risk premiums, and continued evidence that the AI infrastructure cycle is spreading beyond U.S. mega-cap technology. The latest headlines around a potential US-Iran framework, reopening of the Strait of Hormuz, immediate oil sanctions relief, and a rebound in tanker traffic helped reduce global macro tail risk. At the same time, semiconductor, data-center, and AI supply-chain news continued to support countries with direct exposure to chips, hardware, automation, and advanced manufacturing.

The strongest 1-month country ETF returns were concentrated in two groups: AI-linked Asia and cyclical/geopolitical rebound markets. South Korea (EWY) and Taiwan (EWT) led the universe, rising 15.12% and 13.71%, respectively, underscoring how much international equity leadership remains tied to the semiconductor and AI hardware cycle. South Korea (EWY) is more exposed to memory, high-bandwidth memory, displays, and electronics supply chains, while Taiwan (EWT) remains the clearest single-country proxy for advanced semiconductor manufacturing.

That leadership comes with an important caveat: the best AI-linked performance did not always come with fresh buying. South Korea (EWY) lost $913M over 1 month despite retaining $3.88B of YTD inflows, while Taiwan (EWT) lost $130M over 1 month and remains in YTD outflow. Investors are still paying for AI exposure, but they are also managing concentration risk, geopolitical risk, and profit-taking after a powerful run.

Top 10 and Bottom 10 Country ETF Performers — 1M Return

The table shows that performance and flows are sending different signals. The AI leaders, South Korea (EWY) and Taiwan (EWT), generated the strongest 1-month returns but saw 1-month outflows. That does not mean investors are abandoning the AI trade. It suggests they are becoming more tactical, using strength to rebalance rather than blindly adding exposure. The same dynamic is visible in Brazil (EWZ), which remains a major YTD flow winner but suffered nearly $900M of 1-month outflows as investors took profits or reduced cyclical emerging-market risk.

Japan (EWJ) remains the cleaner international AI-adjacent story even though it did not make the top 10 1-month return table. Japan (EWJ) gained 3.90% over 1 month while attracting $728M of 1-month inflows and $4.26B YTD. That flow consistency matters. Japan (EWJ) offers exposure to semiconductor equipment, factory automation, electrical equipment, robotics, and advanced manufacturing, but with a more diversified developed-market structure than Taiwan (EWT) or South Korea (EWY).

The AI footprint is largest in markets tied to chips, equipment, memory, and data-center infrastructure. Taiwan (EWT), South Korea (EWY), Japan (EWJ), the Netherlands (EWN), Germany (EWG), and China (MCHI) sit closest to that investment chain. Taiwan (EWT) is the foundry and advanced manufacturing proxy. South Korea (EWY) is the memory and hardware beta vehicle. Japan (EWJ) and the Netherlands (EWN) are more equipment- and industrial-enabler exposures. Germany (EWG) is more indirect, tied to automation and industrial cyclicality. China (MCHI) has AI scale, but remains constrained by export controls, national-security policy, and weak investor confidence.

Supplemental research reinforces that point. MSCI recently noted that Taiwan became the largest weight in the MSCI Emerging Markets Index at 24.8% as of April 30, 2026, driven by AI semiconductor demand, while emerging-market information technology rose to nearly 37% of the index. That means the AI trade is no longer just a U.S. mega-cap theme; it has become a major driver of emerging-market index composition and relative performance.

The AI theme also has a power and infrastructure dimension. The IEA estimates that the U.S. and China will account for nearly 80% of global data-center electricity-demand growth through 2030, with Europe and Japan also seeing meaningful increases. That supports the case for AI-linked countries with power infrastructure, equipment, and grid-investment exposure, but it also introduces a constraint: AI leadership may increasingly depend on electricity availability, permitting, cooling, and infrastructure execution rather than just chip demand.

The countries less dependent on AI to outperform are equally important for portfolio construction. Canada (EWC), the UK (EWU), Switzerland (EWL), Chile (ECH), Peru (EPU), UAE (UAE), Singapore (EWS), and parts of Latin America and the Middle East can work through commodities, financials, defensives, rate sensitivity, domestic policy improvement, or geopolitical normalization. These markets may become more valuable if investors begin to question AI profitability, semiconductor capacity, export controls, or power availability.

Canada (EWC) remains one of the clearest non-AI developed-market allocation stories, with $494M of 1-month inflows and $1.72B YTD. The UK (EWU) and Switzerland (EWL) also continue to attract capital, supported by quality, dividends, healthcare, financials, and defensive global revenue exposure. Chile (ECH) and Peru (EPU) are more commodity-sensitive, while UAE (UAE) benefits from geopolitical relief, energy normalization, and regional capital-market development.

The bottom 10 table also shows that weak performance does not always mean investors are leaving. Indonesia (EIDO), Hong Kong (EWH), Israel (EIS), and Finland (EFNL) all lagged on a 1-month basis but still attracted 1-month inflows. That pattern suggests some investors are using weakness to build exposure in countries where the medium-term story remains intact. By contrast, China (MCHI), Turkey (TUR), Denmark (EDEN), Malaysia (EWM), and Norway (ENOR) showed weaker performance with negative 1-month flows, making them less compelling from a near-term momentum and allocation perspective.

The conclusion is that international equity leadership is no longer simply about owning broad EAFE or emerging-market beta. The market is separating countries into AI beneficiaries, AI-adjacent infrastructure enablers, and non-AI diversifiers. If the AI trade keeps leading, Taiwan (EWT), South Korea (EWY), Japan (EWJ), and the Netherlands (EWN) should remain key international transmission channels. If the AI trade cools, the better relative opportunities may shift toward Canada (EWC), the UK (EWU), Switzerland (EWL), Chile (ECH), Peru (EPU), UAE (UAE), and Singapore (EWS), where outperformance does not require another leg higher in semiconductor enthusiasm. The international tape is therefore best described as selective risk-on: investors still want AI exposure, but they are also starting to pay for diversification away from AI concentration.
